Coding
How pixels are coded.
Normally, pixels are uncoded and can be manipulated as you would expect. However some file formats code pixels for compression, and sometimes it's useful to be able to manipulate images in the coded format.
The gaps in the numbering are historical and must be maintained. Allocate new numbers from the end.
Constructors

Instances
DemandStyle
data DemandStyle Source #
See vips_image_pipelinev(). Operations can hint to the VIPS image IO
system about the kind of demand geometry they prefer.
These demand styles are given below in order of increasing
restrictiveness. When demanding output from a pipeline,
vips_image_generate()
will use the most restrictive of the styles requested by the operations
in the pipeline.
VIPS_DEMAND_STYLE_THINSTRIP --- This operation would like to output strips
the width of the image and a few pels high. This is option suitable for
point-to-point operations, such as those in the arithmetic package.
This option is only efficient for cases where each output pel depends upon the pel in the corresponding position in the input image.
VIPS_DEMAND_STYLE_FATSTRIP --- This operation would like to output strips
the width of the image and as high as possible. This option is suitable
for area operations which do not violently transform coordinates, such
as vips_conv().
VIPS_DEMAND_STYLE_SMALLTILE --- This is the most general demand format.
Output is demanded in small (around 100x100 pel) sections. This style works
reasonably efficiently, even for bizzare operations like 45 degree rotate.
VIPS_DEMAND_STYLE_ANY --- This image is not being demand-read from a disc
file (even indirectly) so any demand style is OK. It's used for things like
vips_black() where the pixels are calculated.
See also: vips_image_pipelinev().
Constructors
| DemandStyleError | No description available in the introspection data. |
| DemandStyleSmalltile | demand in small (typically 64x64 pixel) tiles |
| DemandStyleFatstrip | demand in fat (typically 10 pixel high) strips |

Extend
See vips_embed(), vips_conv(), vips_affine() and so on.
When the edges of an image are extended, you can specify how you want the extension done.
VIPS_EXTEND_BLACK --- new pixels are black, ie. all bits are zero.
VIPS_EXTEND_COPY --- each new pixel takes the value of the nearest edge
pixel
VIPS_EXTEND_REPEAT --- the image is tiled to fill the new area
VIPS_EXTEND_MIRROR --- the image is reflected and tiled to reduce hash
edges
VIPS_EXTEND_WHITE --- new pixels are white, ie. all bits are set
VIPS_EXTEND_BACKGROUND --- colour set from the background property
We have to specify the exact value of each enum member since we have to keep these frozen for back compat with vips7.
See also: vips_embed().
Constructors
