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( [ int surfaceIndex, ] element texture [, int x, int y, int width, int height ] )

Required Arguments

  • texture : The texture element to get the pixels from

Optional Arguments

ADDED/UPDATED IN VERSION 1.3 r4021:
  • surfaceIndex: Desired slice to get if the texture is a volume texture, or desired face to get 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 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.
