Description tilde 2006-10-13 06:21:48 UTC
Horizontal- and vertical-only shadows of a text frame in a PDF export are displayed incorrectly in acroread 7 for GNU/Linux (KPDF displays them correctly). Printing to .ps is affected apparently. Steps to reproduce: Start oowriter Create a text document Add a text frame Go to context menu, Area Choose Fill -> Color -> White Choose Shadow -> [X] Use Shadow Direct shadow to a single edge (i.e. left, right, top or bottom, not a corner) Export to PDF View in acroread for GNU/Linux, current version is 7.0.8 => the display renders artefacts, thin lines at unintended edges. In the example (see below) a thin line is visible spanning the textframe at the lower edge from the right edge minus the width of the shadow. Further tests: A sample .odp, .pdf and .ps and a .png screenshot of the incorrect render taken from acroread are at http://linuxfoo.de/tech/ooo/broken-shadow/ The same problem occurs for example with speech bubbles or pie charts at their horizontal resp. vertical lines as well as for rectangular shapes. Printed to file, the artifacts show in gs 8.15.3 (ESP Ghostscript) and gv 3.6.2. The artifacts do not show in KPDF 0.5.4 (KDE 3.5.4). My theory is that KPDF employs either adaptive or incorrect calculation. Theory: A calculation error during export to either PS or PDF renders unidirectional shadows one pixel too tall/wide orthogonally to the direction of the shadow. Thus, the shadow rectangle is becoming visible at unintended horizontal resp. vertical edges of the frame.

I checked with "2.0.2 German version WIN XP: [680m5(Build9011)]" and can confirm those artifacts (seen with AR 7.0.9, FoxitReader and GV) for PDF export from reporter's test file 'broken-shadow.odt' and also for PDF-export from own WRITER and DRAW documents. It seems that the problem is not limited to uni-oriented shadows.
