Apache OpenOffice (AOO) Bugzilla – Issue 83399
Jagged and unsteady lines on screen display
Last modified: 2008-10-07 19:45:21 UTC
When using polygons for more complex curves the lines on screen display often look jagged and unsteady as if they got some wrong points caused by rounding errors or similar or as if not the full given resolution from the screen was used for rendering. Examples are e.g. circle shapes, pie charts, linear regression curves in charts, free hand curves in draw, a lot of custom shapes, etc. I'll attach a document containing examples.
Created attachment 49493 [details] example with living shapes
Created attachment 49495 [details] screenshot from draw and pdf export
In the attached screenshot I marked the points where you can see wrong pixels. As comparison I added how Adobe reader displays the PDF export. This is a strong indication that not the geometry information itself is wrong but instead there is an error on the way to the screen.
->Armin, you told me that this will probably be solved with the primitives with aw033. Can you please take care of this issue. Not sure, maybe there is something more to do in vcl or in the canvas implementations or so? Thanks a lot!
AW: Yes and No. For 3.0, we will have the primitives and will be able to support AntiAliasing (AA) on different systems. Initially, we will probalbly have Unix/Linux and Solaris. For Windows, support from VCL-Team is needed. Since this is not clarified (the time constraints for the needed ressources are not clarified) i cannot promise this for 3.0 (depending on the System), but we are working on this intensively. Setting the decision makers on copy, changing to enhancement.
AW: Adapting target to primitive move to 3.1.
AW: With aw033 and primitives (since DEV300 m30), the basics for this task are implemented. The missing rest of this task is double to #i28526# to which i will set this one double. *** This issue has been marked as a duplicate of 28526 ***
AW: Closing.
