Icon to BitMap

Posted on: 2016/9/5 19:52 #1

Just popping in

How do I get an icon's render image copied to a bitmap?


struct DiskObject *icon = NULL;

icon = IIcon->GetIconTags(NoInfoBuffer,

    ICONGETA_FailIfUnavailable, TRUE,

    ICONGETA_UseFriendBitMap, TRUE,

    ICONGETA_Screen, PID->Screen,

TAG_END);



PID->OrigWidth=64;   // get the icon's dimensions

PID->OrigHeight=64;  // not use these defaults



if (!(PID->OrigBM=IGraphics->AllocBitMapTags(PID->OrigWidth,PID->OrigHeight,32,

    BMATags_PixelFormat, PIXF_A8R8G8B8,

    BMATags_Clear, TRUE,

    BMATags_Displayable, TRUE,

TAG_DONE)))

{

// error

}

How do I get the icon->do_Gadget.GadgetRender copied to the PID->OrigBM? I always end up with a solid grey block.

I want to use a bitmap because down the road there could be some scaling (I know it can be done above in loading).

And I want no border/text.

Not too shy to talk

do_Gadget.GadgetRender has no meaning on OS4, it only contains some kind of legacy image for compatibility with old programs.

You can use IconControl to read the pixel data of the real image.

Or just use DrawIconState to render the icon into the bitmap.
