Add a square with the text

[EyalMichaeli]

Hi

I didn't understand if I can add a square automatically with the text annotation. and if so, how?

Yes, you can.

Attaching a working code that can make a box and a background color.

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:
blue = [0.75, 1, 1]
yellow = [1, 1, 0.75]
green = [0.75, 1, 0.75]

Font Colors:
black = [0, 0, 0]

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(),

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()
])

I just did similar things and hope my script could help you a bit.

            a.add_annotation(
                'square',
                Location(x1=x1, y1=y1, x2=x2, y2=y2, page=page),
                Appearance(stroke_color=(1, 0, 0), stroke_width=2),
            )
            a.add_annotation(
                'text',
                Location(x1=x1+5, y1=y1, x2=x2, y2=y2, page=page),
                Appearance(
                    fill=[0.4, 0, 0],
                    stroke_width=1,
                    font_size=10,
                    content=filename,
                ),
            )

The +5 in the text annotation is for a left padding of 5 points from the outer border.

The difference between x1 and x2 could be calculated by the number of characters x (font_size / 2).

The difference between y1 and y2 is font_size.
