BitmapSize

Action

Specify the Screen Drawing Bitmap Size (for the current Bitmap Handle)

 

 

Syntax

BitmapSize Filter, Wrapx , Wrapx ,Width, Height 

 

 

Remarks

Filter	Bitmap Filtering Mode, NEAREST or BILINEAR
Wrapx	Bitmap x wrap mode, REPEAT or BORDER
Wrapx	Bitmap y wrap mode, REPEAT or BORDER
Width	Drawn bitmap Width, in Pixels
Height	Drawn bitmap Height, in Pixels

 

This command controls the drawing of bitmaps: the on-screen size of the bitmap, the behavior for wrapping, and

the filtering function. Please note that if Wrapx or Wrapy is using REPEAT then the corresponding memory layout dimension

(BitmapLayout linestride or height) must be power of two, otherwise the result is undefined.
