I'm using Debenu Quick PDF Library 11.14.

I have a Delphi code that injects a raster image to PDF page. It works as expected on most PDFs, but one PDF causes an issue. Here is the code:

---

PDF := CoPDFLibrary.Create;

PDF.LoadFromFile('d:\TestDocs\EasyRecovery622 User Guide_EN.pdf', '');

PDF.SelectPage(1);

Height := PDF.PageHeight;

Width := PDF.PageWidth;

PDF.AddImageFromFile('d:\TestDocs\test.png', 0);

ImgHeight := PDF.ImageHeight;

ImgWidth := PDF.ImageWidth;

PDF.DrawImage(10, Height - 10, ImgWidth, ImgHeight);

PDF.SaveToFile('d:\TestDocs\embedded.pdf');

---

I expect that the image will be embedded at the left top corner of the page and will be fully visible. With the attached PDF I can see only a small part of the image after saving the target 'embedded.pdf' doc. Is it a bug of the library or something is wrong with my source 'EasyRecovery622 User Guide_EN.pdf' doc?

Here is the problem PDF and sample PNG image:

Thank you in advance.

Hi Olo,

if you wanna tell QuickPDF where to draw an image

you should tell where the starting point should be.

With SetOrigin you can do this:

An additional thing you should have an eye on is that sometimes

pdf-pages are made in portrait mode and later rotated to landscape.

So a NormalizePage first should be always good:

Cheers and welcome here,

Ingo

Hi Ingo,

Normalization worked like a charm! Thanks a lot.

Best regards,
