Description

This object is a simple ICC transform that allows mapping of simple RGB spaces to other simple RGB spaces using one, two or three ICC profiles.

This object is not supposed to re-implement LCMS, and if you need anything more complicated then you are better off using lcms2 directly.

                                                         gpointer data_in,

                                                         GError **error);

Processes a block of data through the transform. Once the transform has been setup it is cached and only re-created if any of the formats, input, output or abstract profiles are changed.

`transform` :	a CdTransform instance.
`data_in` :	the data buffer to convert
`data_out` :	the data buffer to return, which can be the same as `data_in`
`width` :	the width of `data_in`
`height` :	the height of `data_in`
`rowstride` :	the rowstride of `data_in`, typically the same as `width`
`cancellable` :	A `GError`, or `NULL`
`error` :	A `GCancellable`, or `NULL`
Returns :	`TRUE` if the pixels were successfully transformed.
