New issue 1318 by psaravi...@gmail.com: Picture and Table border overlaps
https://bugs.chromium.org/p/pdfium/issues/detail?id=1318

Hi team,

The image and table border has been overlap. we found that the image generated in the Pdfium have the same behavior at different magnification values. We exported the images in Pdfium at 100 and 200 percentage zoom values.
The Pdf document and output images was attached for reference.

We had used the below code:

Int Width, Height = 0;

IntPtr data;

For 100 Percentage =>Width = 1836; & Height = 2372; data = 0x12120000;

For 200 Percentage => Width = 3672; & Height = 4748; data = 0x13be0000;

IntPtr createdpages = PdfiumViewer.FPDFBitmap_CreateEx(Width, Height, 4, data, bitmapImage.Width * 4);

PdfiumViewer.FPDFBitmap_FillRect(createdpages, 0, 0, Width, Height, background);

PdfiumViewer.FPDF_RenderPageBitmap(createdpages, pages, 0, 0, Width, Height, 0, 0);

Kindly check this issue with the above code and let me know the solution to resolve this issue.

OS details: Windows 10 Pro Version 1809 (OS Build 17763.379).

Please let me know if you have any concern.
Regards,
Aravindh Ps.

I didn't accept the bug. Comment 4 did.

Based on my testing, I cannot reproduce this issue. Attached is the rendering output I see at 1836x2372. Here, the image is right next to the table. There's no excessive overlap as seen in AtZoomPercentage100.png.

Hi the...@chromium.org ,

Thank you for the clarification. The issue was previously mark as accepted [https://bugs.chromium.org/p/pdfium/issues/detail?id=1318#c4] and later it was changed to Available. Can you please let me know if this was fixed in the recent versions of PDFium. If so, please share the version details.

Since the original bug reporter did not specify what version of PDFium they used, I tried PDFium from early June, 2019. The rendering is the same as comment 11. While the overlap does happen at smaller image dimensions, at 1836x2372, there is no overlap. So AFAICT, this bug can't be reproduced with the given parameters.

Original bug reporter: So are you happy with the current PDFium rendering at 1836x2372?

Hi the...@chromium.org,

I am following it up this issue on behalf of the original bug reporter. We have used the version which is older to the June, 2019. Currently I am building the latest source for Windows to confirm the issue is fixed in the recent versions.

Hi the...@chromium.org

Just for your kind information. I am yet to test it in the latest version and I am still building the dll for Windows. I will update the results here once I tested it successfully.

Confirmed that rendering this PDF with the build of pdfium_test at the scale of 100% and 200%, borders are not overlapping.
However when opening the PDF in the latest build of chrome PDF viewer ( version 88.0.4316.0) at scale level 100%, overlapping is still happening.
