Problem with RenderPageToStream

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   We have QuickPDF 5.11, we use .dcu in Delphi. We are using the RenderPageToStream function to get a Preview of a Pdf Page, but with some pdf we have memory problems, in debug time we get an "out of memory" error in uPDFFlate, in the computers that have few memory (256 or 512 Mb) the application hangs up, in the computers that have more memory (1Gb) the application continues after this error and few time later the preview image appears. The problem is that we cannot capture this "out of memory" error because it is handled internally and the application goes on and the program hangs up, if we can capture this error whe could show an advetising message to the user.

We try:
use the SetTempFile  ---> no results.
use RenderToFiles instead of RenderToStream  ---> same problem
use all the image formats (jpg, git, bmp, wmf,...) ---> same problem
use SavePagePreview ----> poor quality

Help please.

	Carlos, I have sent an email direct to you. As I told you there you should test your PDF file with the latest version of QuickPDF (5.22). Your file works fine on my machine so I believe you have to do an upgrade. If it does not work with the newest version write me back and I will do more intensive tests for you.
