JpegLib， 图片库 JpegLib是一款免费开源的图片库，我用它将bmp转换成jpg。下面是代码： #include "BMPFILE.H" #include "Jpegfile.h" BOOL BMP2JPG(const char *bmp_file, const char *jpg_file) { try { BMPFile bmpFile; BYTE *m_buf; UINT m_width, m_height; m_buf = bmpFile.LoadBMP(bmp_file, &m_width, &m_height); if ((m_buf==NULL) || (bmpFile.m_errorText!="OK")) { m_buf=NULL; return false; } JpegFile::BGRFromRGB(m_buf, m_width, m_height); // vertical flip for display JpegFile::VertFlipBuf(m_buf, m_width * 3, m_height); // we vertical flip for display. undo that. JpegFile::VertFlipBuf(m_buf, m_width * 3, m_height); // we swap red and blue for display, undo that. JpegFile::BGRFromRGB(m_buf, m_width, m_height); BOOL ok = JpegFile::RGBToJpegFile(jpg_file, m_buf, m_width, m_height, true, 75); // quality value 1-100. delete [] m_buf; return ok; } catch(...) { } }
