程序首先读BITMAP 文件的各像素点的RGB值, library 做压缩 RGB 缓冲区成JPEG文件或缓冲区.-procedures first reading of the document BITMAP point pixel RGB value, library so compressed RGB JPEG files into the buffer zone or buffer zone.

bmeps converts bitmap images (PNG/JPEG/NetPBM) to EPS and PDF. EPS level 1, 2 or 3 can be created using run-length compression, flate compression and ASCII-85-encoding. PNG alpha channels can be transferred to PDF or converted to EPS/PDF image masks.

将位图转换成jpeg压缩图像，转换速度很快，且通过代码设置参数得到不同质量的jpeg图像，对于开发相关工程很有帮助。-To convert bitmap converted to jpeg image compression, fast, and jpeg images of different quality is obtained by code set parameters, helpful for development of related engineering.
