Bug ID: 425916 Summary: Black lines on the top and left edges appear when rotating a video by 180 degrees Product: kdenlive Version: unspecified Platform: Manjaro OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Video Display & Export Assignee: j...@kdenlive.org Reporter: secretagent0...@gmail.com Target Milestone: --- Created attachment 131249 --> https://bugs.kde.org/attachment.cgi?id=131249&action=edit Attachment contains image before and after rotation by 180 degrees SUMMARY When rotating a video by 180 degrees, on top and on left edge black lines appear that are 1 pixel wide. The same happens if an image is rotated (See Attachment) STEPS TO REPRODUCE 1. Load image (with exact dimensions as project) 2. Rotate that image by 180 degrees using Rotate (keyframable) 3. Extract frame, or render as image sequence to get rotated image OBSERVED RESULT On top and on left 1 pixel wide lines appear, and on bottom and right image is cropped by 1 pixel. The color of those lines that appear is the background color chosen in rotation (it is black when the background is transparent). EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION It seems that the center of rotation is a particular pixel, and not the center of image, which would be on the line between pixels. -- You are receiving this mail because: You are watching all bug changes.
