#650 new defect/bug

OSD transparency in some cases does not work

Reported by: niccolo Owned by: KaZeR
Priority: minor Milestone: version 0.6.0
Component: core Version: git master
Severity: Keywords: alpha, transparency, map, style, design


I have navit svnr3535 on OpenMoko FreeRunner, using internal gui.

It seems that the osd transparency works only if RGB components are 00 or FF.

An example:

background_color="#ff0000a0" works (get semi-transparent red). background_color="#fe0000a0" does not work (get opaque red).

May be it is related to bg #584

This is true for gtk graphics. For exmple I tried #111111aa which does not work, however if I change the base color to #000000 it works flwlessly in gtk graphics.

It works with sdl graphics, though.

Another example, where transparancy does not work: background_color="#000000ff" (it should be black without transparence).

With minimal change to background_color="#000000fe" it works fine.

Testet with build 3794 on WinCE.

  • Keywords alpha transparency map style design added
  • Milestone set to version 0.5.1

IMHO this is heavy related to #1136. The alpha is buggy because of the way we currently implement the processing.

Will schedule it to 0.5.1
