The invention relates to a processing method for drawing a large pixel picture. The processing method comprises the following steps: according to the size of the drawn picture, dividing the picture into a plurality of canvases capable of completely drawing the picture; calculating the offset distance between the coordinate origin of the segmented picture and the coordinate origin of the actual large picture; drawing the local images of each canvas in turn, and generate BMP format files respectively; loading data of each BMP file and integrating each BMP file format to obtain a final picture file format; intercepting bitmap data of each BMP file and splicing each part of bitmap data; outputting the preset picture header and the bitmap data after stitching and saving to the final BMP file tocomplete the output of the mosaic. The processing method can overcome the problem that the large pixel picture is difficult to be drawn completely at one time, and the processing method is simple tooperate and convenient to realize.
Description
Technical field [0001] The invention relates to the field of software image processing, in particular to a processing method for drawing large-pixel pictures. Background technique [0002] The program uses the common drawing tool library to draw pictures. There are often certain restrictions on the pixel size of the picture. When the pixel size of the picture exceeds its limit, the program can only draw a part, not a complete picture, which becomes a drawing The technical bottleneck of oversized pixel images. For example, using the drawing tool library provided by C# and C++ to draw a 61250*17710 pixel BMP format two-color image can only draw a partial image of 61284*8778 pixels or 30642*17555 pixels. Refer to the attached drawings for details, where figure 1 Is the goal to draw pictures, figure 2 with image 3 Actually draw an incomplete picture. Summary of the invention [0003] Based on this, it is necessary to deal with the problem that the drawing software in the prior art...
