I am getting odd image issues when I export to pdf (or anything) some images are squished, some pngs lose their alpha…? Thoughts?
I just did a quick test .odp file and all images checked out, PNGs were transparent. “Pre-flight” your document, open those images in an image editor (GIMP, Photoshop, etc.) and make sure they are displaying correctly there (you never know what can go wrong! ). If everything checks out externally, your images are ok in your ODP, but the PDF is still wrong, let us know what version of LO, which OS and any other pertinent info.
