The invention discloses a two-dimension image rotation processing method and a processing device The two-dimension image rotation processing method includes steps of computing to obtain a source matrix according to an original image; generating a target matrix corresponding to the source matrix according to the rotation angle; scanning the target matrix by sub matrixes, reading element data fromthe source matrix according to the scanning results and element corresponding relationship between the target matrix and the source matrix, and performing assignment operation to elements in the sub matrixes according to the read element data Matrix elements in the source matrix correspond to pixels of the original image one by one, the number of lines of the sub matrixes, which is larger than or equal to 2, is smaller than that of the target matrix The two-dimension image rotation processing method and the processing device increase data utilization rate in two-dimension image rotation processing

The invention provides a rotating tag creating method and a rotating tag creating system, wherein the rotating tag creating method comprises the following steps that a located region of a rotating tag to be created is controlled to rotate by a prestored rotating angle, and in addition, the rotating tag to be created is controlled not to rotate along with the region; the rotating tag to be created is controlled to be restored to an initial position before the region rotation along with the region for completing the rotating tag creation. Through the technical scheme provided by the invention, the effect of dynamically loading the rotating tag is achieved, the code processing quantity for creating the rotating tag is reduced, and in addition, according to the method and the system, the attributes of data sources of the tag can be conveniently and fast set and modified in the rotating process, so that a user can flexibly, conveniently and fast carry out attribute setting and modification on the created rotating tag, and the user experience is improved.

The partial image rotating device includes the first buffer memory, frame buffer memory, drawing module, rotating object determiner and rotating module. The buffer memory is used to store the first rotating picture corresponding to the first virtual picture. The drawing module is used to draw based on the received second cirtual picture information and store the second virtual picture in the first buffer memory. The rotating object determiner is used to determine the varying object in the second virtual picture based on the first virtual picture and the second virtual picture, and the rotating module is used to rotate the varying object into one rotating object, and replace the partial image of the varying object with rotating object.
