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] In the following, the present invention will be further described in conjunction with the embodiments.

[0007] A method for exporting AutoCAD large image high-pixel bitmaps in batches is as follows. Take the AutoCAD2008 example image db_samp.dwg as an example. The image needs to be exported with high pixels. For example, to export a BMP file with a height and width of 12000*12000 pixels, the BMP file capacity 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 enter the center point of the export area (0,0), length 12000mm, width parameter 12000mm, the number of horizontal blocks is 2, the number of vertical blocks is 2, which is to export in the mode of 2 rows and 2 columns to export the total block of the image The number is 4, and the export file name is a BMP file starti...

Abstract

The invention discloses a bulk block high pixel bitmap exporting method of an AutoCAD large image. Secondary development is carried out aiming at AutoCAD2008 by using Object ARX2008; automatic block batch exporting is carried out on the large image so as to generate high pixel bitmaps according to the total height and width of the to-be-exported large image; file numbering is carried out automatically; follow-up image processing operation is only carried out on a certain block bitmap; the capacities of bitmap files are clearly 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 exporting AutoCAD high-pixel bitmaps in batches and blocks, and belongs to the technical field of image processing. Background technique [0002] With the popularity of computers in factories, more and more companies use AutoCAD software for drawing, and the drawn images are getting larger and larger, such as architectural design drawings, ship design drawings, etc. At some point, it is necessary to transfer the drawn graphics. One method for image processing into high-pixel bitmaps is the function of exporting bitmaps that comes with AutoCAD, but this function is similar to the screen printing function, the resolution is very low, and the high-pixel export effect cannot be achieved. AutoCAD's virtual printing function can realize the export of high-pixel bitmaps, but because some of the images drawn in AutoCAD are very large, high-pixel images are direc...
