Low quality on first page of png from PDF

[rodcas_1]

We currently have a problem, we are using the Spire.Officefor.NETStandard + SkiaSharp.NativeAssets.Linux.NoDependencies library.
This is because the Docker image is on Linux. The problem is that when we save the first page as image and we need to put a stamp, if there is previously another stamp, the quality of the previous stamp image looks very low.

Here is my code.

Code: Select all

Stream stream_img = pdfDoc.SaveAsImage(0);

We converted directly to stream because we used an image in Docker Linux and left out Drawing

Do you have any suggestions on how to improve the quality of an image that already has a previous stamp?


Thank you very much in advance

Kind regards
Rod
