[reportlab-users] Problem with transparent png's

[Tamonash Roy]

Hi !
I've created a pdf document which has a lot of images in it. These images
are transparent png images. In my development machine I have windows with
python 2.5 and reportlab2.2, whereas in the server it is debian linux,
python2.5 and reportlab2.2. The problem is I have a perfect pdf document
while I use my development machine, but when the pdf is generated in the
server and downloaded, the transparent images have a black background. I got
to use these images in the document but dont know how. please help!

Sample code used to generate pdf is as follows:

        f2 = Frame( inch*1.75, inch*7.6,  inch*4.75, inch*2.95,
leftPadding=0, bottomPadding=0,rightPadding=0, topPadding=2, showBoundary=1)
        f3 = Frame( inch*1.25, inch*5.75,  inch*3.85, inch*1.7,
leftPadding=0, bottomPadding=0,rightPadding=0, topPadding=2, showBoundary=1)

mainPage = PageTemplate(frames=[f2, f3])
doc = BaseDocTemplate('report_1.pdf',  pageTemplates=mainPage, leftMargin=72
,title=Title, author=Author, showBoundary=0)

story = []
story.append(Image("a.png"))
story.append(FrameBreak())
story.append(Image("b.png"))

doc.build(story)

Thanks,
Tamonash Roy
