This function sets the pixels of a texture element. It can be used with a standard texture, render target or screen source. Only 'plain' format pixels please.
Performance note:
- This function is slow and not something you want to be doing once a frame.
- It is very slow when setting pixels to a render target or screen source.
- And is very slow indeed if the texture format is not 'argb'
Syntax
bool dxSetTexturePixels ( [ int surfaceIndex = 0, ] element texture, string pixels [, int x = 0, int y = 0, int width = 0, int height = 0 ] )
Required Arguments
- texture : The texture element to set the pixels of
- pixels : The 'plain' format pixels to use
Optional Arguments
- surfaceIndex: Desired slice to set if the texture is a volume texture, or desired face to set if the texture is a cube map. (Cube map faces: 0=+X 1=-X 2=+Y 3=-Y 4=+Z 5=-Z)
By default the pixels are set starting at the top left corner of the texture. To set a different region, define a rectangular area using all four of these optional arguments:
- x: Rectangle left position
- y: Rectangle top position
- width: Rectangle width
- height : Rectangle height
Returns
Returns a string if successful, false if invalid arguments were passed to the function.
