Re: Fwd: [gsl-dev] replace the .bmp splashscreen

Hi Philipp,

Philipp Lohmann a écrit :

The intro bitmap does not involve any SalObject; mpSysObj will always be 
NULL here.

Ok, thank you very much for the information. This will save me a lot of 
time !


 >  From my side, I'd finaly prefer the clipping solution suggested by 
Thorsten, and that I mentioned in a previous mail


That is the right thing to do IMHO; it will work out of the box on all 
platforms. For performance reasons it might be advisable to set a mask 
instead of a region, but we'd need additional code to do that.

Ok, so I started with the first methode  (make it work first ;-)  And I 
think I progressed.

Here is my code (with a very good explanation from Thorsten, about how 
to proceed) : http://paste.lisp.org/display/79096#1

Everything is put in loadPng(), just after the line :  _aIntroPng = 
vcl::PNGReader(*s).Read();
.. but it does not work. Probably something dumb, I don't know exactly.

After some investigations, it seems that my problems are :

- what exact Rectangle use ? e.g. Rectangle()  without anything seems to 
work
- when using a Point, nothing is shown if the cooredinates are inferior 
(both x and y) to 100 ??
- Does  Window::SetWindowRegionPixel( aOpaqueRegion ) really work as 
expected

Any help is of course appreciated :)

Thanks in advance !

Eric
