将C语言图形下的图形转换为16色BMP图-C language graphics conversion of graphics to 16 BMP color map

地图中等值线的识别与矢量化，可以实现从栅格地图（目前支持bmp,emf等文件）中获取等值线.GIS工程有用的。-contour map of identification and vectorization, can be achieved from the raster maps (currently supports bmp, catalog, etc.) access contours. GIS projects useful.

说明：GraphicEx.pas文件使得TImage支持30多种图象格式，有TIFF images(*.tif *.tiff), SGI images(*.bw, *.rgb, *.rgba, *.sgi), ZSoft Paintbrush images(*.pcx, *.pcc), Kodak Photo-CD images(*.pcd), CompuServe images(*.gif), Photoshop images(*.psd, *.pdd), Paintshop Pro imag
