Description: I have a 16"x9" chart in a spreadsheet I created years ago. (Chart originally resized by Right-Clicking chart > Position and Size > **Size** Width: 16" Height: 9".) If I "Export As Image", the resulting PNG is very low resolution compared to how it used to be. Steps to Reproduce: 0. Open attached ODS document. 1. **Right-Click** the chart > **Export As Image**, then output a PNG. Actual Results: A 943x530 PNG. Expected Results: A 1536x864 PNG.

I can confirm this. Works OK in "lastest" of the 6.1 repo, and broken in "oldest" of 6.4 repo, thus this is a regression in 6.2 or 6.3. Need someone who has these two repos to bibisect.
Exporting with the context menu, doesn't ask for the parameters, what does Menu/File/Export, can that help?
This seems to have begun at the below commit. Adding Cc: to Armin Le Grand; Could you possibly take a look at this one? Thanks 5c3d2b64707bda48d657225e0fbd744f70ada793 is the first bad commit commit 5c3d2b64707bda48d657225e0fbd744f70ada793 Author: Jenkins Build User <tdf@pollux.tdf> Date: Fri Aug 17 21:35:11 2018 +0200 source 046df0a876b3d948bb1e14443c00c180bc8cccaa https://git.libreoffice.org/core/+/046df0a876b3d948bb1e14443c00c180bc8cccaa tdf#105998: Enhanced fix for MetafileToBitmap at better place
*** This bug has been marked as a duplicate of bug 126319 ***
Hey Armin, I don't believe this exact bug was ever fixed. Looks like the: - "Duplicate" bug 126319 was fixed/closed. - Fixed in 7.3.2 + 7.4.0. - I just tested on 24.2.1, and it was still good. - raal's Comment 7 bisected THIS issue to the THAT same commit. But this specific "low resolution" export issue is still broken. - - - I can still reproduce my comment 0 in: Version: 24.2.1.2 (X86_64) / LibreOffice Community Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac CPU threads: 8; OS: Windows 10.0 Build 22631; UI render: Skia/Raster; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded I even bibisected everything in: - win64-24.2 - linux-64-24.2 - linux-64-7.6 - linux-64-7.4 - [...] and then: - linux-64-6.2 leads me to the exact commit raal hit in comment 7. - - - Steps to Reproduce: In Calc: 0. Open attachment 177579 [details]. 1. "Right-Click > Export as Image" on the chart. 2. Name your file + save as PNG. Actual Results: - A 943x530 PNG. Expected Results: - A 1536x864 PNG. (16"x9" * 96 dpi)
Indeed, the exported image is still 943x530 pixels, so it seems the issue isn't fixed. Tested with LO 24.8.0.0.alpha1+ (71f3be3bee2e8a07f85594c02a9b44627b219e95) / Ubuntu.
This bug happened long time before 2022. I have been waiting for this bug to be fixed for a decade. I remembered that, since 2015, I used Draw to create a banner with mixed images and exported it with customized settings of output size or resolution and I always get the output with exactly the same dimension. I also used Calc to do many things with the need of exporting as images and I got the same results. Still waiting for the feature. And still wonder why the importance of this bug is set to minor or medium. I find that one of the most important feature in LibreOffice is the PDF Export which is available long before MS Office has it. And I find that many times we need to export something as nice as PDF but without the possibility for anyone to extract embeded images from it so Image Export is nearly as important as PDF export.
