Why are some GIFs drawn incorrectly?

[G-e-C-i]

Hello everyone,

I have the following question. I have GIFs that are displayed incorrectly in the PDF (pages with A4). And I can't find a way to draw them correctly.

I embed the images as follows:
using var bitmap = SKBitmap.Decode(gifBytes);
canvas.DrawBitmap(bitmap, 10, 10);

Data from the GIF:
182x42 96dpi 8Bit

Even if I do the following, the image is blurred:
canvas.DrawBitmap(bitmap, SKRect.Create(10, 10, 182f * 72f / 96f, 42f * 72f / 96f));

My question now is, why is the image so blurred?

Best regards and many thanks

Edit:
Here is a sample file that does not work either:

I have found the error. I had created a new SKDocumentPdfMetadata for SKDocument.CreatePdf(...) but not set EncodingQuality, so the images were not saved without loss.

Sorry for the inconvenience.
