Description: Tested with writer. When i insert a PNG file (on purpose, e.g. a scanned signature) without a background, a PDF export file shows still a slight grey background. Also, printings of the .odt file with colour show that grey background. Even a PNG with a paper white background will produce that grey background. That makes an signature looking ugly and non professional. Steps to Reproduce: 1.Create a PNG(e.g. a handwritten signature) without background 2.Insert it in a L.O.writer page 3.export to PDF or print the page in colour mode Actual Results: Instead of only seeing the signature alone, you will see the signature with a grey background in size of the whole PNG Expected Results: I want to only see the handwritten signature Reproducible: Always User Profile Reset: No, i happens on may three different Linux PCs Additional Info: User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:54.0) Gecko/20100101 Firefox/54.0

Note a bug! Problem occurs when the background of a Picture e.g. JPEG is removed with GIMP, by using "Colour to Alpha" which is translated in German as "Colour to transparence". If you use that function and export the picture as an PNG File without a background it seems to work. I used my scanned signature that way with Microsoft Word (at work) for years. But you have delete the background explicitly in Gimp to make it work as desired. It's been my fault, but I wanted only to help, by reporting that bug Sorry!
