This function fetches the pixels from a texture element. It can be used with a standard texture, render target or screen source.
Performance note:
- This function is slow and not something you want to be doing once a frame.
- It is slower when reading pixels from a render target or screen source.
- And is very slow indeed if the texture format is not 'argb'
Syntax
string dxGetTexturePixels( element texture [, int x, int y, int width, int height ] )
Required Arguments
- texture : The texture element to get the pixels from
Optional Arguments
By default the pixels from the whole texture is returned. To get only a portion of the texture, 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 'plain' format pixels string if successful, false if invalid arguments were passed to the function.
