4 years ago Hi Stanley,
I ran into the same issue, and Michael brayent helped me. This is the working code:
-- coding: utf-8 --
""" Creation date: 02 sep 2020
author: Eyal Michaeli, Eyalmichaeli98@gmail.com purpose: for studies annotations inputs: protocol name
- SDTM Excel file
- ALS Excel file
-
Study PDF file to be annotated outputs: Annotated PDF file
What this function does:
This function gets:
- text_to_annotate: the annotation content
- page number
- locations x1, y1, x2, y2.
- backColor: background color(e.g: blue = [0.75, 1, 1])
- type: the type of annotation content(gets domain, cat, scat). The rest is a 'normal' annotation
-
bold: boolean, True if you want the annotation content to be bold. False is the default. note: is makes the annotation bold by adding one more annotation.

Font size:

Background Colors:

Font Colors:
black = [0, 0, 0] red = [1, 0, 0]
def add_text_with_rect(text_to_annotate, page, x1=20, y1=750, x2=135, y2=775, backColor=blue, type='', bold=False): font_size = regular_font_size font_color = red # can be changed
# Adds the annotation:
content_stream = ContentStream([
Save(),
FillColor(backColor[0], backColor[1], backColor[2]),
Rect(x1, y1, x2 - x1, y2 - y1),
Fill(),
BeginText(),
FillColor(font_color[0], font_color[1], font_color[2]),
Font('MyFont', font_size),]) content_stream.extend(get_text_commands( x1, y1, x2, y2, text=text_to_annotate, font_size=font_size, wrap_text=True, align=constants.TEXT_ALIGN_LEFT, baseline=constants.TEXT_BASELINE_TOP, line_spacing=1.2, )) content_stream.extend([ EndText(), StrokeColor(0, 0, 0), Rect(x1, y1, x2 - x1, y2 - y1), Stroke(), Restore(), ]) appearance = Appearance( appearance_stream=content_stream, fonts={'MyFont': FreeText.make_font_object()}, ) crf.add_annotation( 'square', location=Location(x1=x1, y1=y1, x2=x2, y2=y2, page=page), appearance=appearance, )
If you want the annotaion content to be BOLD:
if bold == True:
crf.add_annotation(
'square',
location=Location(x1=x1, y1=y1-5, x2=x2, y2=y2, page=page),
appearance=appearance,
)
content_stream.extend([
FillColor(0, 1, 0),
StrokeAndFill()
])
Thanks for this excellent package development and sharing!
I got a question and not sure whether there is any configuration that could be used to configure the background color of the text type annotation. As the snapshot below shows, the filling color was not set, I assume the parameter "fill" for text type means the font color, I also tried to change stroke color but does not take effect. Is there any metadata parameter for this purpose? I checked the source code but not find the approriate configure. Please advise. Thanks a lot for any idea sharing!
Here is the annotation code used for this demo:
