[reportlab-users] Strange rendering of radio buttons

Tue Oct 8 07:12:22 EDT 2024

The below dummy code should be enough to demonstrate the problem. Please note I am setting the size to 12 explicitly. Based on my testing, this is the part that causes the trouble. Once the PDF is generated, I am opening it up with Adobe Acrobat.

from reportlab.pdfgen import canvas
from reportlab.pdfbase import pdfform

def create_simple_radios():
    c = canvas.Canvas('simple_radios.pdf')

    c.drawCentredString(300, 700, 'Radio demo')
    form = c.acroForm

    form.radio(name='radio1', value='value1', x=110, y=650, size=12)
    form.radio(name='radio1', value='value2', x=110, y=600, size=12)
    form.radio(name='radio1', value='value3', x=110, y=550, size=12)

    c.save()

if __name__ == '__main__':
    create_simple_radios()

Hello Martynas,

You're welcome, that's interesting, in which case could you please share the code you're using to generate the radio buttons?

Kind Regards,
Ben Hassell

Hi Ben,

Thank you for your kind suggestion. Based on my test, "forceBorder" does not have any impact on this behaviour. It was previously set to a default value (I assume it defaults to False). I also tried setting it explicitly both to True and False. It results in a mis-rendered radio button.

Thank you.
Martynas

Hello Martynas,

Could you please see if the forceBorder is set and if so try unsetting it?

Kind Regards,

Hi Andy,

Thank you for responding so quickly. I must admit that this is the first time I am using reportlab, I do not have any prior experience.

For reference, this is how the problem looks like on my side (only if the radio button is smaller than 20 points).

Hi Brijunas,

Thanks for reporting this. We have not changed any code relating to form widgets in many years.  Which version were you using previously which worked OK? We can investigate

Hi,

I have noticed a strange behavior of radio buttons with reportlab 4.2.5. The problem shows only when the size of a radio button is set to less than 20 points. If a resulting PDF document is opened in Adobe Acrobat afterwards, strange rendering artifacts can be seen once the button is hovered over or clicked. I would appreciate any advice in this matter.

Thank you.
