Top-level structure describing raster layout for all separations, frames, planes, channels, and colorants in a page.
| unsigned int RASTER_LAYOUT::bandheight |
The number of lines in a regular band, in pixels. The last band in each frame may contain fewer lines than this.
| unsigned int RASTER_LAYOUT::bands_per_frame |
The number of bands in each frame of each sheet. This is ceiling(height/bandheight).
| unsigned int RASTER_LAYOUT::height |
The height of the raster, in pixels (equivalently, the number of lines represented in the raster).
| uint32 RASTER_LAYOUT::layout_id |
The layout identifier changes whenever there are significant changes to a layout. It may be used as a first check to determine if layouts are different, but should not be used as a definitive equality check. Copies of a raster layout may share the same ID until modified. The ID zero is never used by the RIP.
| unsigned int RASTER_LAYOUT::n_rendered_sheets |
The number of non-omitted sheets in the page. This is the number of separations that will be rendered.
| unsigned int RASTER_LAYOUT::n_sheets |
The number of sheets in the layout. A sheet is a unit of output. There will always be at least one sheet in a raster layout.
| hq_atomic_counter_t RASTER_LAYOUT::refcount |
Reference count for the raster layout. References to the raster layout may be acquired to prevent pointers to the sub-structures becoming invalid. All references acquired must be released. This field should not be manipulated directly by the user, only through the provided function calls.
| RASTER_SHEET** RASTER_LAYOUT::sheets |
An array of RASTER_LAYOUT::n_sheets pointers to sheet structures.
| unsigned int RASTER_LAYOUT::width |
The width of the raster, in pixels. This excludes any padding for alignment or strides.
