Below is a copy of email sent to your email address (alrewards.com) on Apr. 07, 2011

I had no problems to convert an HTML with your image to PDF (see attached).

Is it exactly the same image, that caused the problem? As I see in your HTML sample there is no test_png.png reference.

Also in the servlet code please try to invoke
http://pd4ml.com/api/org/zefer/pd4ml/PD4ML.html#useHttpRequest(HttpServletRequest,%20HttpServletResponse)
method before pd4ml.render()

Does it change anything?

#28474

hello

ok i will try again to do the change that you are refering to but please tell me exactly what do you mean by this

Also in the servlet code please try to invoke
http://pd4ml.com/api/org/zefer/pd4ml/PD4ML.html#useHttpRequest(HttpServletRequest,%20HttpServletResponse)
method before pd4ml.render()

can you please clarify

thanks

Before

pd4ml.render();

call in your servlet code you need to invoke

pd4ml.useHttpRequest(httpRequest, httpResponse);

(where parameters are HttpServletRequest httpRequest and HttpServletResponse httpResponse)

#28477

hello
i tried that but its not working , i get the same error . i am sure its the png image i mean if i change the type of the image to any other type then its ok but when i try png its not working

please help me

#28478

hello

this issue has been hanging for long time . please can i get an answer

thank you

#28479

As we wrote you before, the problem is caused by a corrupted PNG file. The original file seems to be ok, but probably it is damaged on the way to PD4ML. PD4ML only states that during parsing of the image by particular offset if found garbage instead of a numeric value.

Today we’ll prepare a version with a binary data dump, to check what is actually returned by PNG request. We’ll send you the version by email.

#28480
