Hello,

I'm using SaveImageListItemDataToFile to extract images from a pdf.

It works great for non transparent images, but I don't know how to extract as PNGs.

If an image has one mask, it's detected as JPG or BMP in GetImageListItemIntProperty(h,i,400), and I lost mask information.

How to extract a mask linked to an image?

In what cases GetImageListItemIntProperty(h,i,400) will return 4 (PNG) ?

Thank you,

Jordi

Well, based on the link try using the forum search feature and search for "Extracting images png tiff issues" without the quotes.
