PdfAddTrueTypeFont OutOfMemory

[payne296]

Hey all,

I'm creating a massive batch of pdfs, and about 6000 in I get an OutOfMemory exception when trying to add a font. This isn't actually a memory issue, and my assumption is that the GDI handles aren't being disposed for the fonts and it's running out of handles. I add three fonts per PDF, and if I comment one of them out I can make it to around 8,000 before the error occurs.

I call PdfEndPdf at the end of every PDF, but is there some other way to dispose of all PDF resources or all GdPictureImaging resources so I can avoid this issue?

Hi,

I identified a small unreleased GDI resource in this method .
Maybe it is the cause of the problem. The next update, which will be published within 5 days will include the fix.

Kind regards,

Thanks Loic, I'm not sure why GDI has to be so finnicky.

The problem still exists. I don't think the issue is actually with the PdfAddTrueTypeFont method, but with the fact that the font that is added with that method is not disposed with PdfEndPdf. Here is, in short, what I'm doing.

Code: Select all

for (int i = 0; i < paths.Length; i++)
{
   int pdf = gdPictureImaging.PdfNewPdf(paths[i]);
   int arialBold = gdPictureImaging.PdfAddTrueTypeFont(pdf, "Arial", true, false);
   int arialPlain = gdPictureImaging.PdfAddTrueTypeFont(pdf, "Arial", false, false);
   int timesNewRoman = gdPictureImaging.PdfAddTrueTypeFont(pdf, "Times New Roman", false, false);

   ... pdf code...

   gdPictureImaging.PdfEndPdf(pdf);
}

I leak three GDI objects every iteration. My assumption was that PdfEndPdf would deallocate those fonts, but that doesn't seem to be happening. Is there any other way for me to deallocate those resources?

Any help would be appreciated, this is a huge issue for me.

OK perfect,
I made the test with 1.000.000 of documents with 0 byte of memory leak
