Dont measure others giving by your own needs, or youll always complain. A simple method to convert WMF files into TGA files (Beijing changping universitys intelligent engineering research room 102249) Abstract: primitive Windows files (*. WMF) provides a lot of, colorful clipart, its file format is different from general image file, it only records GDI functions to draw pictures, show pictures of process is a process to perform these functions, due to take up the space is small, the equipment has nothing to do, so for those who repeatedly played occasion. TGA file format is currently widely used video file formats, the rich resources of clip art used in TGA file, making video subtitles broadcast is a very meaningful work, but the WMF files and TGA file format is different, especially the WMF files to (r, g, and b) image color, TGA file to (r, g, b, a) said the image color, a for the transparency of the image. So how to add a property to the WMF file data is a problem. One solution is to try to all GDI functions in simulation WMF files, but the cost is too high, this paper, by using Virtual c + + provides a powerful CDC class zone operation function, success to distinguish WMF files in the image and background, puts forward the WMF image resources into the TGA file two-step. In this paper, five GDI functions of the corresponding regional functions are also presented in this paper Key words: WMF file image processing file format area function The introduction If Microsofts MS Office software is used, it would be a surprise to see the thousands of rich and colorful clip art files offered by Microsoft. Microsoft calls this file Windows metafile, because its smaller and more device agnostic than bitmap files, so its appropriate for places that are played repeatedly in applications. To gen
