[reportlab-users] bug with image transparency?!

[Volker Haas]

Hi,

I guess I just ran into an image which is not rendered correctly using 
reportlab (version 2.1).
All black pixels are rendered white (or transparent on a white background).
The image displays correctly in a browser or image viewer.

This is what PIL tells me about the image:

In [1]: from PIL import Image
In [2]: img = Image.open('MergeSampleStep1.png')
In [3]: img.mode
Out[3]: 'P'
In [4]: img.info
Out[4]: 
{'Software': 'Paint.NET v3.35',
 'gamma': 0.45455000000000001,
 'transparency': 255}


Sample code:


from reportlab.platypus import BaseDocTemplate, PageTemplate, Frame, Image
from reportlab.rl_config import defaultPageSize

doc = BaseDocTemplate("test.pdf")

frame = Frame(0,0,defaultPageSize[0], defaultPageSize[1])
doc.addPageTemplates(PageTemplate(frames=frame))

Story = [Image("MergeSampleStep1.png")]
doc.build(Story)
