New commits: commit 77d2bbaa18e0be5347d7bd7167b245264789e0a4 Author: Miklos Vajna <vmik...@collabora.com> AuthorDate: Tue Jan 4 16:28:03 2022 +0100 Commit: Miklos Vajna <vmik...@collabora.com> CommitDate: Tue Jan 4 19:02:03 2022 +0100 sc export chart as graphic: handle PDF The context menu for Calc charts would call into GraphicFilter::ExportGraphic(), which has explicit code for e.g. SVG, but not for PDF. The graphic exporter to PDF is only meant to work with images backed with PDF data, not with all shapes. Fix the problem by explicitly handling PDF in GraphicHelper::SaveShapeAsGraphic() in svx/, and invoking the normal PDF export in that case. Continue to fall back to XGraphicExportFilter for other formats. This requires passing down the current document from sc/.
