[WD20] PDF to Images

Hi everyone

I'm trying to convert a PDF to Images using PDFExtractPage and dSaveImagePNG in WinDev 20, but sometimes the image is wrong, I think is because of the way the PDF was created, I think the wrong images belong to PDFs created with several PNG images.

Can anyone help me?
TIA

Here are the Images
