patshi Posted July 29, 2021 Share Posted July 29, 2021 Hi, I recently run in a bug with _WinAPI_StretchBlt. If I scale an image over a specific size (SourceImage: 1860x77524) to a destination size of 1860x58143 pixels the function fails with an error (error: true, extended: 0). Below this size (for example as source size 1860x66114) works. I dont know where exactly the threshold of error is, but the lower resolution works and the higher not. It seems to be connected to the function _WinAPI_SetStretchBltMode($hCompDC, $STRETCH_HALFTONE). If I create the WinAPI buffer without the better antialiasing $STRETCH_HALFTONE, the _WinAPI_StretchBlt function does not fail. I used beta v3.3.15.4 What could cause this? Any help appreciated. Thanks, Patrick. Link to comment Share on other sites More sharing options...
