Bug ID: 93462 Summary: Lossless compression in ‘Export as PDF’ doesn’t work—PNG images get distorted Product: LibreOffice Version: 4.4.4.3 release Hardware: x86-64 (AMD64) OS: Linux (All) Status: UNCONFIRMED Severity: normal Priority: medium Component: Draw Assignee: libreoffice-bugs@lists.freedesktop.org Reporter: presentmeaninv...@gmail.com Paste a PNG image into drawing via ‘Insert’ → ‘Image’. I’ve used this one: https://mega.nz/#!4o8mCaAJ!uEioSdvzNAv2cZULRF0IZhnnlRKqQyvVotlB2IzvMkw Then try to ‘File‘ → ‘Export as PDF…’ and then choose ‘Lossless compression’ under ‘Images’ in the ‘General’ tab. Uncheck ‘Reduce image resolution’ if it’s set. Open the resulting PDF in the viewer of your choice. Then save the image to a file. Open the file in GIMP. Go to ‘Image’ → ‘Image properties’, the file type should be detected as PNG. Check the file size and notice how it changed. Use a colour picker tool to compare backgrounds—in the image I’ve used the background colour was #CCDED8 and after export to PDF it became #CFE0DA. This isn’t what ‘lossless compression’ should do. -- You are receiving this mail because: You are the assignee for the bug.
