There is a problem with this jPedal library in the way that it renders images from PDF documents. I have an example PDF document in which a white image that is layered above a colored image renders transparently when the entire document is converted to an image.
I used the jPedal library that was originally shipped with CF9 and it works fine; this hotfix and the jPedal library that ships with CF10 do not work. Is there any way that you can get a newer version of jPedal? I can send you an example of what is happening. Thank you.
Here is some more information about what is happening:
I have a relatively simple PDF. It is located at:
As you can see, there is a colored circle, and inside it is a white icon. These were created by layering images.
Using jPedal getPageAsHiRes(), the image is converted to a PNG. The PNG file can be found here:
As you can see, the white icon was converted to transparency in the conversion.
This behavior does NOT happen with a previous jPedal version that was shipped with ColdFusion 9. It occurs with the version that ships with CF10 as well as the CF9 Hotfix version.
Does anyone from Adobe read these forums?
Occasionally, but not officially.
If you need to open a support ticket with them, you need to actually do that: open a support ticket.
These forums are basically community-driven.
I saw your questions, but did not know the answers, so ignored them I'm afraid.
registered as bug #3584640. To users who don't use jPedal directly, it affects cfpdf, action="thumbnail" also.
