Hi,
Concerning drawAlphaRect, Damien implemented this functions some time
ago, but hasn't commited it yet.
I read your patch Michael, and some things have to be changed/corrected.
For example, for the transparency you use: 1.0f/nTransparency, but
according to the win32 implementation, nTransparency is between 0 and
255, so here's what we have to do: ((float)(255-nTransparency)/255)
because the OOo transparency value of 0 corresponds to the quartz
transparency value of 1, and the OOo transparency value of 255
corresponds to the quartz transparency value of 0. Also, in your patch
it seems that you don't use the current fill color value (which belongs
to the aquasalgraphics class).
I propose that you merge your patch with damien's because these 2
patches have both good things and uncompleted parts that are completed
by the other patch.
Here's damien patch:

Hi Michael,
I noticed in the console that RefreshRect is called sometimes when
there is not a valid mrView, and also that drawAlphaRect was not
implemented.
Yes, indeed.
So I have created a patch that addresses these issues.
Thanks :)
It is attached. Check it out if you have some time.
Hmmm ... no, it isn't attached
Maybe because we have stu^^^strong anti-viruses filtering mails ;)
