Bug ID: 150875
Summary: Hatch pattern scaling depends on DPI (screen scaling)
on PDF export
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: [email protected]

Export with screen scaling 100% vs 150%
Using the unit test document for tdf#147027, run this command line:
> soffice --convert-to pdf vcl/qa/cppunit/pdfexport/data/tdf147027.ods
Depending on current desktop scaling, the hatch pattern used in the chart would
have different scale in the output PDF.
The attached screenshot shows the difference with two screen scaling values
using
Version: 7.4.1.1 (x64) / LibreOffice Community
Build ID: 0a046a10cbf1679eea5538bd3ab63156caa3a036
CPU threads: 12; OS: Windows 10.0 Build 19044; UI render: Skia/Raster; VCL: win
Locale: ru-RU (ru_RU); UI: en-US
Calc: CL
The same result would be with documents created from scratch:
1. In a new Writer document, insert a shape;
2. In its area properties, select a hatch pattern;
3. Use toolbar button to export to PDF.
Before a workaround implemented in commit
3801a45eb8e82095d5f1a65ad1646e300a900bdd, the respective unit test failed on
screen scaling other than 100% with:
> C:/lo/src/core/vcl/qa/cppunit/pdfexport/pdfexport.cxx(2253) : error :
> Assertion
> Test name: `anonymous namespace'::testTdf147027::TestBody
> equality assertion failed
> - Expected: 778
> - Actual : 1754
