The issue can be reproduced. Need change the bug status to CONFIRM
A first look, seem the table bg color with transparent had issue. The transparent value can not be set correctly. I will dig into the issue.
reproduce the issue
After more investigation, I have found the root cause. There is a function named as: void ApplyCellAttributes( const SdrObject* pObj, Reference< XCell >& xCell ) in main\filter\source\msfilter\svdfppt.cxx The function will apply the attributes for the cell of tables in SD application. Here is the codes for processing the transparent of the background cell color --------------------------------------------------------------------------- sal_Int16 nFillTransparence( ( (const XFillTransparenceItem&)pObj->GetMergedItem( XATTR_FILLTRANSPARENCE ) ).GetValue() ); if ( nFillTransparence != 100 ) { nFillTransparence *= 100; static const rtl::OUString sFillTransparence( String(RTL_CONSTASCII_USTRINGPARAM( "FillTransparence" ) ) ); xPropSet->setPropertyValue( sFillTransparence, Any( nFillTransparence )); } ------------------------------------------------------------------------ The var nFillTransparence is ranged from 0(solid) to 100(completed transparent). So the nFillTransparence *= 100; is complete wrong. It should be removed. And when nFillTransparence == 100 need to be set the value too, otherwise, the color will be solid, not transparent.
Created attachment 78095 [details] tablebg_transparent_sample In the sample file, there is a table with one row and three cell. The first cell bg color transparent value is 0(solid); The second one is 100 and last one is 50.
Created attachment 78100 [details] patch for ppt table background transparent color issue I have test the patch with tablebg_transparent_sample file. Open and save to ppt and ods format, then open again with AOO. It works well.
Reviewed, tested, and applied the patch. SVN revision is 1347577.
confirm fixing the bug on ver 1351249 onn Win7 ,pass
