1 2Differences in borders between Excel and LibreOffice Calc. 3 4The sources for this Document is: 5 - sc/qa/unit/data/ods/test_borders_export.ods (new Test-Document) 6 - sc/qa/unit/subsequent_export-test.cxx (ScExportTest::testBordersExchangeXLSX) 7 8 - sc/source/filter/excel/xestyle.cxx (void lclGetBorderLine) 9 - sc/source/filter/oox/stylesbuffer.cxx (Border::convertBorderLine) 10 11 Bug-Ticket: tdf#79787 12 13 14In LibreOffice the lines are defined by two information: the style and the width of the line. There are seven different line styles available. And the following line width can be selected: 0.05 pt, 0.25 pt, 0.50 pt, 0.75 pt, 1.0 pt, 1.25 pt, 1.50 pt, … until 9pt. 15In Excel you can only define the style of the line. There are 13 different styles available. The width cannot be entered explicitly, instead you have different styles for a solid line with different width (s. Screenshots below). 16The question is now: how to map the borderlines of LibreOffice to Excel and vice versa. 17In the overview below you can see the mapping as it is and some suggestions how to improve it. As the borders are defined different, it will not be possible to define a 1:1 mapping." 18 19The current mapping is mainly defined of the width, but i think better is the line-style, i think user see that first 20 21Base for the evaluation is LibreOffice master (commit [bbfeab3b13b48c99cfa2f94c8c34bc3efef7faa9] ) and Excel 2013 22 23 EXCEL || LIBREOFFICE 24Excel-Line Name Value || LO-Line Name Value 25 None EXC_LINE_NONE 0 || none table::BorderLineStyle::NONE 32767 (-1) 26 1 EXC_LINE_HAIR 7 || 1 table::BorderLineStyle::SOLID 0 27 2 EXC_LINE_DOTTED 4 || 2 table::BorderLineStyle::DOTTED 1 28 3 EXC_LINE_THIN_DASHDOTDOT 11 || 3 table::BorderLineStyle::DASHED 2 29 4 EXC_LINE_THIN_DASHDOT 9 || 4 table::BorderLineStyle::FINE_DASHED 14 30 5 EXC_LINE_DASHED 3 || 5 table::BorderLineStyle::DASH_DOT 16 31 6 EXC_LINE_THIN 1 || 6 table::BorderLineStyle::DASH_DOT_DOT 17 32 7 EXC_LINE_MEDIUM_DASHDOTDOT 12 || 7 table::BorderLineStyle::DOUBLE_THIN 15 33 8 EXC_LINE_MEDIUM_SLANT_DASHDOT 13 || 34 9 EXC_LINE_MEDIUM_DASHDOT 10 || 35 10 EXC_LINE_MEDIUM_DASHED 8 || 36 11 EXC_LINE_MEDIUM 2 || 37 12 EXC_LINE_THICK 5 || 38 13 EXC_LINE_DOUBLE 6 || 39 40In the following cases a 1:1 mapping is not possible. 41 42 Excel -> LibreOffice: Create in Excel and open it in LibreOffice. || LibreOffice -> Excel: Create Sheet in LibreOffice and save as XLSX. 43Create in| In Excel save as XLSX, | In Excel save as ODS,|| Created in | Load saved xlsx-file | Load saved xlsx-file 44Excel2013| Load in LibreOffice | Load in LibreOffice ||LibreOffice with | in LibreOffice | in Excel 45_______________________________________________________________________________________________________________________________________________________ 46 Line |current transformation|new suggestion|current transformation||Line Width |current transformation|new suggestion|current|new suggestion 47 | Line Width | Line Width | Line Width || | Line Width | Line Width | Line | Line 48 13 | 7 2,50 | 7 1,75 | 1 0,05 || 2 0,05 -
