display masked AND scaled bitmaps

[michael.schrenk]

hi all

i'm doing my first steps in symbian-programming for SX1.

is it possible to display bitmaps which are masked AND scaled?


i only found:
BitBlt - to draw unscaled and unmasked bitmaps
BitBltMasked - to draw masked bitmaps
DrawBitmap - to draw scaled bitmaps


is there any function or workaround to draw a masked bitmap every frame in a new size?

thx in advance!

Nope, only way to do it is to scale the image & mask before drawing them.

Anyway, was just looking into SDK docs for CPAlbBitmap and its GetAnimFrameWithMaskL()- function. it seems that it might be able to scale the images & masks during loading them. I never tried scaling on this class, but I think it could be worth of trying anyway.

thx yucca!

i have to scale the masked images in every frame of an animation ... so i think i'll have to do it as you sai in two steps ...

right now i made two offscreen bitmaps. on the first one i draw the correctly scaled bitmaps with DrawBitmap.
on the second one i draw all the masks withe the according position and scale.
after that i draw the two offscreen bitmaps to the display with BitBltMasked.

that works ... but its slow

any better approaches?

but thx for your help so far!!
