+ + +Similar to text fields discussed in the last chapter, PyPDFForm gives you the ability to +modify some styles of checkboxes and radio buttons without changing the template.
+You can change the size of the selection by specifying a float value. Consider
+this PDF:
from PyPDFForm import PdfWrapper
+
+form = PdfWrapper("sample_template.pdf")
+form.widgets["check"].size = 50
+form.widgets["check_2"].size = 40
+form.widgets["check_3"].size = 60
+
+form.fill(
+ {
+ "check": True,
+ "check_2": True,
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+The button style is the shape of the selection on a checkbox or radio button. PyPDFForm lets you pick
+three different button styles: check, circle, and cross. Consider
+this PDF:
from PyPDFForm import PdfWrapper
+
+form = PdfWrapper("sample_template_with_radio_button.pdf")
+form.widgets["radio_1"].button_style = "cross"
+form.widgets["radio_2"].button_style = "circle"
+form.widgets["radio_3"].button_style = "check"
+
+form.fill(
+ {
+ "radio_1": 0,
+ "radio_2": 1,
+ "radio_3": 2,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+The coordinate system on a single page of a PDF starts at the bottom left of the page as the origin. The unit of +the coordinates is called "points" and there are 72 points/inch. PyPDFForm utilizes this coordinate system in +some of its APIs so that widgets, texts, or images can be created on a PDF.
+To allow a better user experience with the coordinate system, PyPDFForm implements a grid view so that there is a +better idea on where stuffs should be placed on a PDF.
+Consider this PDF, the +coordinate grid view can be generated like this:
+from PyPDFForm import PdfWrapper
+
+grid_view_pdf = PdfWrapper(
+ "sample_template.pdf"
+).generate_coordinate_grid(
+ color=(1, 0, 0), # optional
+ margin=100 # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(grid_view_pdf.read())
+The generate_coordinate_grid method takes two optional parameters. The first one is color which allows you to pick
+a color for the grid view. The default color is red. The second one is margin which allows you to change the
+coordinate grid view's margin in points. The default margin is 100 points.
PyPDFForm allows you to draw certain elements on a PDF. The purpose is in case there is a missing widget on your PDF +form, and you need to put certain texts on it, or if you need to draw images.
+This section of the documentation will use +this PDF as an example.
+This section of the documentation requires a basic understanding of the PDF coordinate system.
+All optional parameters will have a comment # optional after each of them.
NOTE: Due to a known bug in a dependency, it is advised that these draw methods are called after +a PDF form is filled. Otherwise, part (most noticeably radio buttons) or even all widgets of the PDF form might +get removed after drawing things on it.
+from PyPDFForm import PdfWrapper
+
+pdf = PdfWrapper("sample_template.pdf").draw_text(
+ text="random text",
+ page_number=1,
+ x=300,
+ y=225,
+ font="your_registered_font", # optional
+ font_size=12, # optional
+ font_color=(1, 0, 0) # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(pdf.read())
+from PyPDFForm import PdfWrapper
+
+pdf = PdfWrapper("sample_template.pdf").draw_image(
+ image="sample_image.jpg",
+ page_number=1,
+ x=100,
+ y=100,
+ width=400,
+ height=225,
+ rotation=0 # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(pdf.read())
+PyPDFForm uses a single depth, non-nested dictionary to fill a PDF form. As a result of this process, the filled +PDF form will be flattened and no longer editable. This is to prevent future encoding issues, especially when +multiple PDF forms with overlaps on widget names are combined together.
+As seen when we
+inspected this PDF, a text
+field can be filled with a value of string, whereas a checkbox can be filled with a boolean value:
from PyPDFForm import PdfWrapper
+
+filled = PdfWrapper("sample_template.pdf").fill(
+ {
+ "test": "test_1",
+ "check": True,
+ "test_2": "test_2",
+ "check_2": False,
+ "test_3": "test_3",
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(filled.read())
+A radio button group on a PDF form is a collection of radio buttons that share the same name.
+A PDF form
+with radio button groups can be filled using integer values where the value indicates which radio button to select
+among each radio button group:
from PyPDFForm import PdfWrapper
+
+filled = PdfWrapper("sample_template_with_radio_button.pdf").fill(
+ {
+ "radio_1": 0,
+ "radio_2": 1,
+ "radio_3": 2,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(filled.read())
+Similar to radio buttons, a dropdown choice can be selected by specifying an integer value of the choice. Consider
+this PDF:
from PyPDFForm import PdfWrapper
+
+filled = PdfWrapper("sample_template_with_dropdown.pdf").fill(
+ {
+ "dropdown_1": 1
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(filled.read())
+A signature field widget allows you to sign a PDF form in a handwritten format. PyPDFForm lets you use a signature image to populate +any signature field widget.
+Consider this PDF +and this signature image:
+from PyPDFForm import PdfWrapper
+
+signed = PdfWrapper("sample_template_with_signature.pdf").fill(
+ {
+ "signature": "sample_signature.png"
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(signed.read())
+NOTE: As described here, the value of the signature in your dictionary can be
+a file path shown above, but also an open file object and a file stream that's in bytes.
NOTE: This is a beta feature, meaning it still needs to be tested against more PDF forms and may not work for +some of them.
+An image field widget can be filled similarly to a signature field, by providing a value of file path, file object, or +file stream.
+Consider this PDF +and this image:
+from PyPDFForm import PdfWrapper
+
+filled = PdfWrapper("sample_template_with_image_field.pdf").fill(
+ {
+ "image_1": "sample_image.jpg"
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(filled.read())
+PyPDFForm is a free and open source pure-Python 3 library for PDF form processing. It contains the essential +functionalities needed to interact with PDF forms:
+It also supports other common utilities such as extracting pages and merging multiple PDFs together.
+After a PDF form is prepared, PyPDFForm can be used to inspect names of all its widgets so that the data +that's needed to fill it can be determined. There are several different methods this can be done with and feel free +to choose the way that fits your needs the most.
+This section of the documentation will use +this PDF as an example.
+The first method of inspecting a PDF form is to generate a preview document. Each PdfWrapper object contains an
+attribute .preview which is a file stream that can be written to any disk file or memory buffer. Consider the
+following snippet:
from PyPDFForm import PdfWrapper
+
+preview_stream = PdfWrapper("sample_template.pdf").preview
+
+with open("output.pdf", "wb+") as output:
+ output.write(preview_stream)
+The generated preview PDF will have the name of each widget labeled on top of it in red.
+The dictionary that's used to fill a PDF form can be described using a JSON schema. For example:
+import json
+
+from PyPDFForm import PdfWrapper
+
+pdf_form_schema = PdfWrapper("sample_template.pdf").schema
+
+print(json.dumps(pdf_form_schema, indent=4, sort_keys=True))
+The above snippet will yield the following output:
+{
+ "properties": {
+ "check": {
+ "type": "boolean"
+ },
+ "check_2": {
+ "type": "boolean"
+ },
+ "check_3": {
+ "type": "boolean"
+ },
+ "test": {
+ "type": "string"
+ },
+ "test_2": {
+ "type": "string"
+ },
+ "test_3": {
+ "type": "string"
+ }
+ },
+ "type": "object"
+}
+In this case sample_template.pdf has three text fields named test, test_2, and test_3 because they all have
+a type of string. It also has three checkboxes check, check_2, and check_3 due to their boolean type.
The JSON schema generated by PyPDFForm can be used to validate against the data you use to fill a PDF form.
+Lastly, PyPDFForm can generate some sample data that can be directly used to fill a PDF form:
+from pprint import pprint
+
+from PyPDFForm import PdfWrapper
+
+pprint(PdfWrapper("sample_template.pdf").sample_data)
+The above snippet will give you a sample dictionary:
+{'check': True,
+ 'check_2': True,
+ 'check_3': True,
+ 'test': 'test',
+ 'test_2': 'test_2',
+ 'test_3': 'test_3'}
+PyPDFForm is hosted on PyPI and any tool that supports downloading from it can be used. +The most common option is to use pip.
+PyPDFForm requires Python 3.8+.
+It is advised that a virtual environment is always created beforehand. Then you can run the following command to install:
+pip install PyPDFForm
+To upgrade PyPDFForm as well as all its dependencies, run:
+pip install -U PyPDFForm
+There are two classes provided by the library that abstract a PDF form. The FormWrapper class allows you to fill a
+PDF form if you don't need any other API. More info about FormWrapper can be found
+here.
The class that implements most of PyPDFForm's APIs is PdfWrapper. It takes various optional parameters to instantiate,
+with the most important one being the PDF form "template".
For example, if you download this PDF, +you will want to instantiate your object like this:
+from PyPDFForm import PdfWrapper
+
+pdf = PdfWrapper("sample_template.pdf")
+PyPDFForm does implement an adapter for different ways Python interacts with files. So you can pass your PDF form to
+PdfWrapper in three different ways: a file path, an open file object, and a file stream that's in bytes.
This means the following two snippets are equivalent to the above:
+from PyPDFForm import PdfWrapper
+
+with open("sample_template.pdf", "rb+") as template:
+ pdf = PdfWrapper(template)
+from PyPDFForm import PdfWrapper
+
+with open("sample_template.pdf", "rb+") as template:
+ pdf = PdfWrapper(template.read())
+This adaptation is universal across all APIs of PyPDFForm. So in later sections of the documentation whenever you see +a function parameter that's a file path you can safely switch them for a file object or file stream.
+Lastly, PdfWrapper also implements itself similar to an open file object. So you can write the PDF it holds to another
+file:
from PyPDFForm import PdfWrapper
+
+pdf = PdfWrapper("sample_template.pdf")
+
+with open("output.pdf", "wb+") as output:
+ output.write(pdf.read())
+And it doesn't have to be a disk file, it can be a memory buffer as well:
+from io import BytesIO
+
+from PyPDFForm import PdfWrapper
+
+pdf = PdfWrapper("sample_template.pdf")
+
+with BytesIO() as output:
+ output.write(pdf.read())
+The most common tool to create a PDF form is Adobe Acrobat. A tutorial can be found +here. +There are other free alternatives like DocFly that support similar functionalities.
+Given a PDF that's not a form yet, PyPDFForm also supports +creating a subset of PDF form widgets on it through coding.
+This section of the documentation will use +this PDF as an example.
+This section of the documentation requires a basic understanding of the PDF coordinate system.
+All optional parameters will have a comment # optional after each of them.
NOTE: For some PDF prep tools, creating widgets on their PDF forms may result in their original widgets getting +flattened (e.g., this PDF +which was prepared using Sejda). So it is advised that you fill them first +before creating any widget using PyPDFForm.
+A text field widget can be created by downloading the PDF and running the following snippet:
+from PyPDFForm import PdfWrapper
+
+new_form = PdfWrapper("dummy.pdf").create_widget(
+ widget_type="text",
+ name="new_text_field_widget",
+ page_number=1,
+ x=57,
+ y=700,
+ width=120, # optional
+ height=40, # optional
+ max_length=5, # optional
+ font="Courier", # optional
+ font_size=15, # optional
+ font_color=(1, 0, 0), # optional
+ bg_color=(0, 0, 1), # optional
+ border_color=(1, 0, 0), # optional
+ border_width=5 # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(new_form.read())
+A checkbox widget can be created using the same method with some changes to the parameters:
+from PyPDFForm import PdfWrapper
+
+new_form = PdfWrapper("dummy.pdf").create_widget(
+ widget_type="checkbox",
+ name="new_checkbox_widget",
+ page_number=1,
+ x=57,
+ y=700,
+ size=30, # optional
+ button_style="check", # optional
+ tick_color=(0, 1, 0), # optional
+ bg_color=(0, 0, 1), # optional
+ border_color=(1, 0, 0), # optional
+ border_width=5 # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(new_form.read())
+The button_style parameter currently supports three options: check, circle, and cross.
A dropdown widget shares a similar set of parameters as a text field, with the only significant difference being
+a list of options needs to be specified:
from PyPDFForm import PdfWrapper
+
+new_form = PdfWrapper("dummy.pdf").create_widget(
+ widget_type="dropdown",
+ name="new_dropdown_widget",
+ page_number=1,
+ x=57,
+ y=700,
+ options=[
+ "foo",
+ "bar",
+ "foobar",
+ ],
+ width=120, # optional
+ height=40, # optional
+ font="Courier", # optional
+ font_size=15, # optional
+ font_color=(1, 0, 0), # optional
+ bg_color=(0, 0, 1), # optional
+ border_color=(1, 0, 0), # optional
+ border_width=5 # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(new_form.read())

There are several different methods this can be done with and feel free to choose the way that fits your needs the most. This section of the documentation will use this PDF as an example. Generate a preview PDF The first method of inspecting a PDF form is to generate a preview document. Each PdfWrapper object contains an attribute .preview which is a file stream that can be written to any disk file or memory buffer. Consider the following snippet: from PyPDFForm import PdfWrapper preview_stream = PdfWrapper(\"sample_template.pdf\").preview with open(\"output.pdf\", \"wb+\") as output: output.write(preview_stream) The generated preview PDF will have the name of each widget labeled on top of it in red. Generate a JSON schema that describes a PDF form The dictionary that's used to fill a PDF form can be described using a JSON schema. For example: import json from PyPDFForm import PdfWrapper pdf_form_schema = PdfWrapper(\"sample_template.pdf\").schema print(json.dumps(pdf_form_schema, indent=4, sort_keys=True)) The above snippet will yield the following output: { \"properties\": { \"check\": { \"type\": \"boolean\" }, \"check_2\": { \"type\": \"boolean\" }, \"check_3\": { \"type\": \"boolean\" }, \"test\": { \"type\": \"string\" }, \"test_2\": { \"type\": \"string\" }, \"test_3\": { \"type\": \"string\" } }, \"type\": \"object\" } In this case sample_template.pdf has three text fields named test , test_2 , and test_3 because they all have a type of string . It also has three checkboxes check , check_2 , and check_3 due to their boolean type. The JSON schema generated by PyPDFForm can be used to validate against the data you use to fill a PDF form. Generate sample data Lastly, PyPDFForm can generate some sample data that can be directly used to fill a PDF form: from pprint import pprint from PyPDFForm import PdfWrapper pprint(PdfWrapper(\"sample_template.pdf\").sample_data) The above snippet will give you a sample dictionary: {'check': True, 'check_2': True, 'check_3': True, 'test': 'test', 'test_2': 'test_2', 'test_3': 'test_3'}","title":"Inspect a PDF form"},{"location":"inspect/#inspect-a-pdf-form","text":"After a PDF form is prepared, PyPDFForm can be used to inspect names of all its widgets so that the data that's needed to fill it can be determined.

The most common option is to use pip. Install using pip PyPDFForm requires Python 3.8+. It is advised that a virtual environment is always created beforehand. Then you can run the following command to install: pip install PyPDFForm To upgrade PyPDFForm as well as all its dependencies, run: pip install -U PyPDFForm Create a PDF wrapper There are two classes provided by the library that abstract a PDF form. The FormWrapper class allows you to fill a PDF form if you don't need any other API. More info about FormWrapper can be found here . The class that implements most of PyPDFForm's APIs is PdfWrapper . It takes various optional parameters to instantiate, with the most important one being the PDF form \"template\". For example, if you download this PDF , you will want to instantiate your object like this: from PyPDFForm import PdfWrapper pdf = PdfWrapper(\"sample_template.pdf\") PyPDFForm does implement an adapter for different ways Python interacts with files. So you can pass your PDF form to PdfWrapper in three different ways: a file path, an open file object, and a file stream that's in bytes . This means the following two snippets are equivalent to the above: from PyPDFForm import PdfWrapper with open(\"sample_template.pdf\", \"rb+\") as template: pdf = PdfWrapper(template) from PyPDFForm import PdfWrapper with open(\"sample_template.pdf\", \"rb+\") as template: pdf = PdfWrapper(template.read()) This adaptation is universal across all APIs of PyPDFForm.

Similar to the PdfWrapper class, the FormWrapper also supports widgets including text fields, checkboxes, radio
+buttons, dropdowns, and paragraphs. However, it does NOT support signature or image widgets.
Consider this PDF:
+from PyPDFForm import FormWrapper
+
+filled = FormWrapper("sample_template_with_dropdown.pdf").fill(
+ {
+ "test_1": "test_1",
+ "test_2": "test_2",
+ "test_3": "test_3",
+ "check_1": True,
+ "check_2": True,
+ "check_3": True,
+ "radio_1": 1,
+ "dropdown_1": 1,
+ },
+ flatten=False, # optional
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(filled.read())
+The optional parameter flatten has a default value of False, meaning PDF forms filled using FormWrapper will by
+default remain editable. Setting it to True will flatten the PDF after it's filled, making all widgets read only.
PyPDFForm gives you the ability to modify certain styles of text fields through code. This allows you to manipulate +appearances of the texts without having to make changes to your PDF form template.
+All these style changes can be done both globally upon instantiating a PdfWrapper object and individually for each
+text field widget.
This section of the documentation will use +this PDF as an example.
+Some fonts, for example Courier and Helvetica, are builtin as part of the PDF standards. These fonts can be set
+without registration:
from PyPDFForm import PdfWrapper
+
+form = PdfWrapper("sample_template.pdf", global_font="Courier")
+form.widgets["test"].font = "Helvetica"
+
+form.fill(
+ {
+ "test": "test_1",
+ "check": True,
+ "test_2": "test_2",
+ "check_2": False,
+ "test_3": "test_3",
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+Other non-standard fonts, for example Liberation Serif, will need +a TrueType file +to be registered before they can be set:
+from PyPDFForm import PdfWrapper
+
+PdfWrapper.register_font("new_font_name", "LiberationSerif-Regular.ttf")
+
+form = PdfWrapper("sample_template.pdf", global_font="new_font_name")
+form.widgets["test"].font = "new_font_name"
+
+form.fill(
+ {
+ "test": "test_1",
+ "check": True,
+ "test_2": "test_2",
+ "check_2": False,
+ "test_3": "test_3",
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+PyPDFForm allows setting font size using a numerical float value:
from PyPDFForm import PdfWrapper
+
+form = PdfWrapper("sample_template.pdf", global_font_size=20)
+form.widgets["test"].font_size = 30.5
+
+form.fill(
+ {
+ "test": "test_1",
+ "check": True,
+ "test_2": "test_2",
+ "check_2": False,
+ "test_3": "test_3",
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+PyPDFForm allows setting font color using an RGB numerical tuple:
from PyPDFForm import PdfWrapper
+
+form = PdfWrapper("sample_template.pdf", global_font_color=(1, 0, 0))
+form.widgets["test"].font_color = (0.2, 0, 0.5)
+
+form.fill(
+ {
+ "test": "test_1",
+ "check": True,
+ "test_2": "test_2",
+ "check_2": False,
+ "test_3": "test_3",
+ "check_3": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(form.read())
+There are some additional utilities PyPDFForm provides similar to many other PDF libraries.
+This section of the documentation will use +this PDF as an example.
+Each PdfWrapper object has an attribute .pages. It's a list of PdfWrapper objects where each one of them is a
+single page:
from PyPDFForm import PdfWrapper
+
+first_page = PdfWrapper("sample_template.pdf").pages[0]
+first_page.fill(
+ {
+ "test": "test_1",
+ "check": True,
+ },
+)
+
+with open("output.pdf", "wb+") as output:
+ output.write(first_page.read())
+More than one PDF files can be merged by simply adding their PdfWrapper objects. Consider
+this PDF:
from PyPDFForm import PdfWrapper
+
+pdf_one = PdfWrapper("dummy.pdf")
+pdf_two = PdfWrapper("sample_template.pdf")
+merged = pdf_one + pdf_two
+
+with open("output.pdf", "wb+") as output:
+ output.write(merged.read())
+Or if you wish to re-organize your pages:
+from PyPDFForm import PdfWrapper
+
+pdf_one = PdfWrapper("dummy.pdf")
+pdf_two = PdfWrapper("sample_template.pdf")
+merged = pdf_two.pages[0] + pdf_one + pdf_two.pages[1] + pdf_two.pages[2]
+
+with open("output.pdf", "wb+") as output:
+ output.write(merged.read())
+PyPDFForm supports modifying PDF version up to 2.0:
+from PyPDFForm import PdfWrapper
+
+new_version = PdfWrapper("sample_template.pdf").change_version("2.0")
+
+with open("output.pdf", "wb+") as output:
+ output.write(new_version.read())
