#include "swhtm.h"
Data Fields | |
| const sw_htm_raster_info * | dst_raster_info |
| Information about the destination raster (page or separation). | |
| unsigned int | src_bit_depth |
| The source raster bit depth to be used. | |
| float | screen_rotation |
If a screening module wishes to honor the /ScreenRotate systemparam (a Harlequin extension), this is the number of degrees of rotation present in the pagedevice, and by which any screen should be rotated. It is zero if /ScreenRotate is false. | |
| sw_htm_coord | phasex |
The x (horizontal) value from the sethalftonephase operator, or its equivalent. | |
| sw_htm_coord | phasey |
The y (vertical) value from the sethalftonephase operator, or its equivalent. | |
| unsigned int | max_render_threads |
| The maximum number of renderer threads the RIP will use. More... | |
| const sw_data_api * | data_api |
| An implementation pointer for access to the sw_datum values in this structure. | |
| sw_datum | colorantname |
| A string sw_datum containing the name of the component screen for which this halftone is being selected. More... | |
| sw_datum | halftonedict |
| A dictionary sw_datum that represents the halftone dictionary. More... | |
| unsigned int | src_values_per_component |
| The number of color values for each component of the source raster. More... | |
| unsigned int | colorant_index |
| Index of the colorant in sw_htm_raster_info::colorant_infos. More... | |
Information passed to the screening module for sw_htm_api::HalftoneSelect().
| unsigned int sw_htm_select_info::colorant_index |
Index of the colorant in sw_htm_raster_info::colorant_infos.
Contains the index for the colorant for which this halftone is being selected. This will refer to the actual spot colorant, even if the halftone dictionary only has a /Default for it. However, the /Default screen will also be set up, and on that call, this will be SW_HTM_DEFAULT_INDEX (not an index of any colorant in the array). This information allows the module to select a specific screen for any spot colorant or provide a shared default.
| sw_datum sw_htm_select_info::colorantname |
A string sw_datum containing the name of the component screen for which this halftone is being selected.
This can be an explicit name from a type 5 dictionary, or the name of a process colorant implicitly declared, or (Default) for spot colorants not explicitly named (but see colorant_index).
| sw_datum sw_htm_select_info::halftonedict |
A dictionary sw_datum that represents the halftone dictionary.
Note that some keys in halftone dictionaries are consumed by the RIP and not passed on to the screening module. These include DetectSeparation, InheritAngle, InheritFrequency, Override, OverrideAngle, OverrideFrequency and TransferFunction.
| unsigned int sw_htm_select_info::max_render_threads |
The maximum number of renderer threads the RIP will use.
| unsigned int sw_htm_select_info::src_values_per_component |
The number of color values for each component of the source raster.
This is determined by the value of the ScreenLevels system parameter at selection time.
If the module cannot work with this setting, it should return SW_HTM_ERROR_UNSUPPORTED_SRC_BIT_DEPTH.
