`Abstract:¬
`11
`¬12
` Transforms the image's pixels from their current encoding to a new
`13
`one. This¬
`…
` is useful for compressing an image and altering the pixel format¬
`14
` for the end display device.¬
`15
`¬16
` A new encoding is specified as a path attribute with the name¬
`17
` "newencoding". It should be a 32 Integer.¬
