Description Regina Henschel 2012-08-17 21:50:43 UTC 
Draw a rectangle and fill it with a rectangular gradient e.g. "Gradient 6".
Context menu > Area > Gradients
Set border and rotation to 0.
Set Center X to 10% and Center Y to 100%.

Notice that the center of the gradient does not move to the bottom of the shape.
Center Y is always the same as Center X, independent from your entry in the field.
I see the same error with style ellipsoid, but not with style radial.

I see this defect only in AOO3.4.1 not on trunk.

ALG: Tried with rev 1372282 AOO3.4.1, could not reproduce. Works the same as with (pretty current) trunk version.

File with picture of the wrong and of the correct display.

The settings are cx="25%" and cy="75%". You can proof it via context menu > Area > Gradient.

The display is cx="25%" and cy="25%".

I've got German AOO 3.4.1 (r1372282) with en-US language pack for Windows.

My new trunk build (r1374948) has the error too.
My build r1370716 has a correct display.

Export to bitmap is OK, only display is broken.
Comment 3 Armin Le Grand 2012-08-23 15:55:04 UTC 
ALG: The AOO3.4.1 shows the correct display (using the test file under Win7). My new trunk build also shows the correct display. Both have Cx=25 and cy=75. Sorry, cannot reproduce.
Comment 4 Regina Henschel 2012-08-23 16:31:53 UTC 
Hi Armin,

please switch off "Anti-Aliasing". If I turn it on, the display is correct; if I turn it off, the display is wrong.
Comment 5 Armin Le Grand 2012-08-23 18:00:39 UTC 
ALG: Hi Regina,
this explains it: when switching off, the old direct V L renderers are used; as explained these may be buggy in some respects. Do you think it needs fixing, who is working without AA? I even think we will remove AA someday. If fix is needed, it could be done using the primitives, though.
BTW: out for one week from now...
Comment 6 Regina Henschel 2012-08-23 18:54:30 UTC 
I personally like to work without Anti-Aliasing. Using it makes lines look blurred and I try to focus.
