SaveAsImage returns Image with incorrect size under Debugger

[kulov]

Hi,

I am using FreeSpire.PDF to load PDF document using new PdfDocument().LoadFromFile(filename);
Then I call SaveAsImage(0, 300, 300) to create Image object.
It all used to work fine until recently when I found that the returned Image object differs if the program is run with the Debugger or without.

When I run the application using F5 I get Image object that is 6000x8587.
Same file, same code - just rerun this time with Ctrl+F5 and I get Image object that is 2400x3437.

The same code works on another machine with F5 and with Ctrl+F5 and returns the correct object size of 2400x3437.

Any idea what could be reason that under debugger the image object is 2.5 times larger?

Can it be related to any High DPI settings?

Thank you,
Martin

Hi Team,

we are getting the stack overflow exception on the saveasImage method, when we try to extract the image of the PDF.

Dear Rachel,

It seems that the issues is replicated with any pdf on my machine.
I am using Microsoft Surface laptop with Windows 10 with 250% font increase.

Please see attached wikipedia.pdf to replicate the issue using FreeSpire.PDF 5.10.0 NuGet package.
Attached are also output png files as a result of SaveAsImage(0, 300, 300) for both with and without debugger.
I have made screenshot of my Windows font scaling settings which correspond to the 2.5 times increase of dimensions between two output image files.
Thank you,
Martin
