Embodiment Construction
[0029] In the embodiment of the present invention, in order to improve the accuracy of image path trap generation and improve the applicability of image path trap generation, as figure 1 As shown, a method for generating a trap for an image path is provided, which specifically includes the following steps:
[0030] S101: According to the intersecting path between each image object and an adjacent primitive object, extract effective data for trap generation from the image object and the primitive object, and determine attribute information of the effective data.
[0031] In the embodiment of the present invention, the primitive objects include: text objects, graphics objects, gradient objects and image objects. In the user space, that is, in each page space, according to the coordinate value of each primitive object point and the bounding box (Bounding Box, BBox) parameter of each primitive object, determine the relationship between each image object and the adjacent image obje...

The invention discloses a method and a device of generating trapping by an image path, aiming at solving the problems existing in the prior art that the precision of processing the trapping generated by the image path is low and the use range of the method of generating the trapping by the image path is narrow. The method of generating trapping by an image path comprises the following steps: effective data for generating trapping are extracted according to the intersected paths of image objects and adjacent graph element objects, the attribute information of the effective data is determined and the graph element objects for generating trapping on all points of the intersected paths are determined; the points of the intersected paths are divided into at least one trapping region according to the graph element objects for generating trapping on all points of the intersected paths; the trapping region is divided into at least one sub-trapping region according to the change of the color gradients of the images on all points of the intersected paths in the trapping region with image objects; and the trapping is generated by the image path according to the trapping principle in each sub-trapping region. The technical scheme can be adopted to effectively improve the precision of processing the trapping generated by the image path and enable the use range of the method of generating the trapping by the image path to be wider.
Description
technical field [0001] The present invention relates to the technical field of trapping processing, in particular to a method and device for generating traps on an image path. Background technique [0002] In the printing process, two adjacent graphic elements with color difference are superimposed, and the graphic elements in the front of the overlapping part will cover the graphic elements in the back. In the printing technology, the graphic elements in the front are called " Foreground", the graphic element behind is called "background". If the colors of the upper and lower graphic elements are different in the superimposed part, then the colors of the upper and lower graphic elements are required to be accurately aligned during the printing and imposition process. Wherein, the primitives may be graphics, text, images, gradient colors, and the like. However, in the actual printing process, due to the instability of the continuous paper, the relative position between the ...
