New commits: commit 6ca971ca3a4b767fdc75cd2dde022a878dd583a1 Author: Miklos Vajna <[email protected]> AuthorDate: Wed Dec 9 17:32:06 2020 +0100 Commit: Miklos Vajna <[email protected]> CommitDate: Wed Dec 9 17:32:14 2020 +0100 vcl: fix logic size of metafile from Graphic vector-7.0 has bitmap import filters which set both the preferred size and the preferred pixel size on a BitmapEx. This means that when ImpGraphic::ImplGetGDIMetaFile() gets the bitmap size, it can use maEx.GetPrefSize() directly. Interestingly, the "fall back to pixel size from logic size" logic is still there at other places, e.g. at ImpGraphic::ImplGetPrefSize(). However, on this branch, the bitmap import filters (e.g. PNG import) only sets the preferred pixel size and set the map mode to pixel. This means that directly getting the preferred size results in a zero size, so exporting such a bitmap to WMF/EMF will result in a white rectangle. Fix the problem by using ImplGetPrefSize() (which has the fallback logic) instead of maEx.GetPrefSize() directly -- both for the metafile action and for the preferred size of the metafile.
