Action
Specify the A-F coefficient of the Bitmap Transform Matrix.
Syntax
BitmapTransform CoefValue , CoefName
Remarks
|
CoefValue |
Coefficient value of the Bitmap Transform Matrix in signed 8.8 bit fixed-point form. The initial value is 256. |
|
CoefName |
Coeeficient name. There are coefficient A-F. You need to specify a capital letter A,B,C,D,E or F. |
BitmapTransform A-F coefficients are used to perform bitmap transform functionalities such as scaling, rotation and translation.
Example
' Pseudocode ' A value of 0.5 (128) causes the bitmap appear double width: BitmapSource 0 BitmapLayout RGB565, 128,64 BitmapTransform 128, A BitmapSize Nearest, Border, Border Begin_G Bitmaps Vertex2II 16,0,0,0
' Pseudocode' A value of 2.0 (512) gives a half-width bitmap: BitmapSource 0 BitmapLayout RGB565, 128,64 BitmapTransform 512, A BitmapSize Nearest, Border, Border Begin_G Bitmaps
Vertex2II 16,0,0,0
