Problems solved by technology

[0005] Compared with the prior art, the beneficial effects of the present invention are: solve the problem of low resolution of the existing drawing bitmap export method in AutoCAD, solve the problem that the large image export high-pixel graphics file capacity is too large, and subsequent graphics processing operations are very time-consuming The problem is that the capacity of the bitmap file after partitioning is significantly reduced, the operation speed is greatly accelerated, and the work efficiency is improved.

Embodiment Construction

[0006] The present invention will be further described below in conjunction with embodiment.

[0007] A batch export method of high pixel bitmap of AutoCAD large image is as follows, taking AutoCAD2008 example image db_samp.dwg as an example, the image needs to be exported with high pixel, such as exporting a BMP file with a height and width of 12000*12000 pixels, and the capacity of the BMP file reaches 420M , using this method to export high-pixel bitmaps in blocks can be divided into 4 blocks and exported in batches. The pixels of each block are 6000*6000, and the file capacity is reduced to 105M. The process is as follows:

[0008] (1) First input the center point (0,0) of the export area, the length 12000mm, the width parameter 12000mm, the number of horizontal blocks 2, the number of vertical blocks 2, that is, export in the mode of 2 rows and 2 columns, and export the total block of the image The number is 4, and the exported file name is a BMP file beginning with pic; ...

Abstract

The invention discloses a high-pixel bitmap batch blocked exporting method of an AutoCAD large picture. An OjbectARX2008 conducts secondary development on AutoCAD2008, according to the total height and the width of the large picture which needs to be exported, high-pixel bitmaps are automatically exported in batches in a blocked mode, files are automatically numbered, only a certain blocked bitmapneeds to be operated in later image processing, the file capacity of the bitmap is obviously reduced, and the operation speed is greatly increased.

Description

technical field [0001] The invention relates to a graphics processing method, in particular to a computer processing method for batch-block derivation of AutoCAD high-pixel bitmaps, and belongs to the technical field of image processing. Background technique [0002] With the popularization of computers in factories, more and more companies use AutoCAD software for drawing, and the drawn images are getting bigger and bigger, such as architectural design drawings, ship design drawings, etc. At some point, it is necessary to transfer the drawn graphics to One method is the export bitmap function of AutoCAD, but this function is similar to the function of screen printing, the resolution is very low, and the export effect of high pixel cannot be achieved. The virtual printing function of AutoCAD can realize the export of high-pixel bitmaps, but because the images drawn in AutoCAD are very large, the high-pixel images are directly exported. , Saving and saving are very slow and ...
