--------- I want to control the drawing text size inside GeUserArea, is this possible? I don't see this in the header functions so it may be hidden somewhere else?

Hi Mohamed,
I don't know any option to influence the font size for GeUserArea::DrawText(). Instead I recommend to use a GeClipMap. There you have full control over the font and its size.

@Andreas , thanks a lot for the hint
any idea where to use it in the GeUserArea as there is no examples at all!! "I need a minimum example of just where to use it, may be 2~4 lines of code will do it"

I think I forgot to search, found some examples here on the forums, I guess there won't be a problem now, will ask again here if there is any problem.

Would be nice if you linked the examples here for the others

it draws the text with red background, I want the background to be transparent, what should I do?

no one knows if this is a bug or not? the Bitmap should be empty, but for unknown reason it fills the Bitmap with the last pen color, any idea how to solve this?

I've also experienced this. DrawBitmap() seems to use the last pen color instead of mixing alpha pixels with the pixels that are already on the GeUserArea.

No need for the explicit additional bitmap and alpha channel allocation. You can set the transparency value with SetColor(r,g,b,a).
i.e. cm->SetColor(r,g,b,128) will give a half transparent output.

yea Samir, but it remains with an unavoidable bug!! , background is not transparent.

I can't confirm. It works. Here is the code:
OffScreenOn(); Int32 w = 100; Int32 h = 100; AutoAlloc<GeClipMap> bmp; bmp->Init(w,h,32); bmp->BeginDraw(); bmp->SetDrawMode(GE_CM_DRAWMODE_COPY,255); bmp->SetColor(255,255,255,0); //Fully transparent bmp->FillRect(0,0,w,h); //Set the whole bitmap transparent bmp->SetDrawMode(GE_CM_DRAWMODE_COPY,255); bmp->SetColor(255,255,255,128); //50% transparent bmp->TextAt(10,10,"Katachi rocks.. :-D"); //Draw text bmp->EndDraw(); DrawBitmap(bmp->GetBitmap(),0,0,w,h,0,0,w,h,BMP_ALLOWALPHA);

Hi Samir,
try to add DrawSetPen(Vector(0.8, 0.2, 0.2)); "or any other color" after OffScreenOn(); and you will find the bug, I tested your code and the same problem appears.

Then don't. Why are you using DrawSetPen?

drawing other stuff prior to texts, should I draw everything in one clipmap? not sure about performance, I will test, it may worth a shot!!

yes, if you don't have a good reason, you should stay with the clip map drawing functions.

after using GeClipMap in all drawings it worked perfectly , thanks all for the help, you can mark this as solved
