When the coordinates of one of the images are adjusted from (X2, Y2) to (X2+ C, Y2+ D) in response to an operation on the other image, the coordinates of the template primitive 200 remain as (X1, Y1) and the coordinates of the other image remain as (X3, Y3).

Based on the characteristic, the content imported through the template graphic element can be synchronously adjusted quickly and efficiently in response to the adjustment of the template graphic element, and the attributes of each content can be independently adjusted in response to the adjustment of the content, so that various printing requirements are realized. In addition, the setting of the template graphic elements, such as editing image fillets and the like, can be changed by responding to the operation on the template graphic elements, namely, the image processing function is integrated in the RIP, so that the redundant process of cooperation of a plurality of pieces of software is optimized when the printing data is edited and generated, particularly, when the image to be printed needs to be repeatedly adjusted, the image to be printed can be directly adjusted in the RIP and directly subjected to rasterization processing in the RIP without frequently transmitting the image to be printed obtained by vector graphic software or image processing software to the RIP, the exchange frequency of the data is greatly reduced, and the generation efficiency of the printing data is improved.

In an embodiment of the present invention, the height and width of the template primitive 200 may be set as the height and width of the printing medium, and the outer border corresponds to the outer edge of the printing medium, and when the setting of the template primitive is changed, whether the printed image exceeds the range of the printing medium may be correspondingly determined by whether the image exceeds the outer border. In another embodiment of the present invention, the outer border also facilitates fast alignment between the stencil primitives 200. In one embodiment of the present invention, at S40: the method for obtaining the printing data for printing by carrying out rasterization processing on the template primitive comprises the following steps: only the content of the template primitive positioned in the outer frame is subjected to rasterization processing, so that the size of the printed image is ensured to be consistent with that of the template primitive 200, and the technical effect of accurately controlling the size of the printed image is realized. In one embodiment of the invention, a warning message is generated in response to the contents of the template primitive exceeding the outer border.
