Hello,

I am trying to convert multiple PDF files into images.

After a certain number of convertions, i constantly got "Out of memory" errors.

I convert my PDF like this  : 

UnicodeString cible = repDiapo + "Diapositive.jpg";
PDFLibrary->LoadFromFile(filename.c_str(), L"");
int nbPages = PDFLibrary->PageCount();
PDFLibrary->RenderDocumentToFile(300, 1, nbPages, 1, cible.c_str());

Do you have any idea how I could avoid this kind of errors ? 

Thanks.
Bye.

Hi Seb,

it depends on what's behind the original pdf.
How many pages... what dimensions?
Regarding this 300 dpi can be too much?
What you can see looking into the task manager while running the function (how much ram needed)?
Perhaps it's better to split this job into parts (keep the actual pagenumber in mind... then a Free... then a new instance)?
I would prefer another idea: Using the DA-functions!

Completely a different way:
What you really wanna do?
Rendering any pdf-pages with text, small pictures and so on?
Or do you want to render images which were inserted into pdf as single pages?
If this is what you want then you can export these images with the original dimensions from pdf page by page without much ram needed.
If this is what you want you should read here:

Cheers and welcome here,
Ingo
