应该多用搜索。也能省点分啊。

何谓高效？
(e.g. TBitmap, TJpegImage效率不够？)

[constantine]

void Bmp2Jpg(String BmpName, String JpgName) //将bmp文件转换为jpg文件
{
Graphics::TBitmap *MyBMP = new Graphics::TBitmap;
try
{
MyBMP->LoadFromFile(BmpName); //图片位置
TJPEGImage *MyJPEG = new TJPEGImage;
MyJPEG->Assign(MyBMP);
MyJPEG->CompressionQuality = 60; //压缩比例 1..100
MyJPEG->Compress();
MyJPEG->SaveToFile(JpgName); //保存路径
delete MyJPEG;
}
__finally
{
delete MyBMP;
}
}

[constantine]

void Jpg2Bmp(String JpgFile, String BmpFile) //将Jpg文件转换为Bmp文件
{
TJPEGImage *MyJPEG = new TJPEGImage;
try
{
MyJPEG->LoadFromFile(JpgFile); //图片位置
Graphics::TBitmap *MyBMP = new Graphics::TBitmap;
MyBMP->Assign(MyJPEG);
MyBMP->SaveToFile(BmpFile); //保存路径
delete MyBMP;
}
__finally
{
delete MyJPEG;
}
}

都这么久了，还不给分。看来又要流标了。
