  Subject: pdf renders garbled png image

Hi,

I am evaluating pd4ml and have run into a problem where, when my test html file references a png image, the image in the resultant pdf file comes out garbled.

I've tested converting the png image to gif, and then the resultant pdf file renders the image correctly, so I'm wondering if there are known bugs regarding png images?

Thanks.

An HTML document sample and its PDF output, sent to support pd4ml com would help us to analyze the problem reasons.

Sure, here's the sample html I'm using (just using wikipedia's png logo to test):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Test</title>
</head>
<body>
<img src="http://upload.wikimedia.org/wikipedia/commons/6/63/Wikipedia-logo.png" />
</body>
</html>

And I've attached the pdf output.

Well, it seems to be .NET specific issue. I've just tested with Java version - everything is ok. See attached.

Which version of PD4ML do you use?

As I see the issue impacts PNG24 images with alpha (translucency) layer only. We've been working on a bugfix.
