The Bitmap class
Use the function GetBitmap(name) to get a read only instance of the
class. It is not possible to change any of the attributes of an
image retrieved by name.
Use the function GetBitmap() to get a writeable instance
of the class, or use the clone() method of an instance to get a
writeable instance.

| matr |
R [/W] |
|

GetImageMatr/SetImageMatr |
| Method |
Returns |
Description |
| load(filename) |
bool |
loads image from given filename (bmp/jpg). Only
possoible for writeable instances. |
| save(filename) |
bool |

| clone() |
Bitmap |
creates a copy of the bitmap. The cloned bitmap
may be modified |
Example 1: Convert an image from color to greyscale
bmp=GetBitmap('Image').clone() #get a copy of the origin bitmap
bmp.pixelFormat = 3 #force greyscale
SetImageMatr('Image',bmp.matr) #writeback the modified image
Example 2: Create a new bitmap
import myImageLib
bmp=GetBitmap()
bmp.pixelFormat = 3 #set greyscale
bmp.height = 480 #set dimensions
bmp.width = 640
myImageLib.foo( bmp.handle ) #modify the image in some 3'rd party library using the bitmap's HBITMAP
SetImageMatr('Image',bmp.matr) #write back the modified image
