the source Babl format

 

dest_profile

the destination GimpColorProfile

 

dest_format

the destination Babl format

 

rendering_intent

the rendering intent

 

flags

transform flags

 

Returns

the GimpColorTransform, or NULL if no transform is needed to convert between pixels of src_profile and dest_profile .

Since: 2.10


gimp_color_transform_new_proofing ()

GimpColorTransform *

This function transforms a contiguous line of pixels.

Parameters

transform

a GimpColorTransform

 

src_format

Babl format of src_pixels

 

src_pixels

pointer to the source pixels

 

dest_format

Babl format of dest_pixels

 

dest_pixels

pointer to the destination pixels

 

length

number of pixels to process

 

Since: 2.10


gimp_color_transform_process_buffer ()

void
gimp_color_transform_process_buffer (GimpColorTransform *transform,
                                     GeglBuffer *src_buffer,
                                     const GeglRectangle *src_rect,
                                     GeglBuffer *dest_buffer,
                                     const GeglRectangle *dest_rect);

This function transforms buffer into another buffer.

Parameters

transform

a GimpColorTransform

 

src_buffer

source GeglBuffer

 

src_rect

rectangle in src_buffer

 

dest_buffer

destination GeglBuffer

 

dest_rect

rectangle in dest_buffer

 

Since: 2.10


gimp_color_transform_can_gegl_copy ()

gboolean
gimp_color_transform_can_gegl_copy (GimpColorProfile *src_profile,

TRUE if pixels can be correctly converted between src_profile and dest_profile by simply using gegl_buffer_copy(), babl_process() or similar.

Since: 2.10

Types and Values

enum GimpColorTransformFlags

Flags for modifying GimpColorTransform's behavior.

Members
