达人们帮帮忙……
要实现1，4，8，24位BMP图像的解码

#include <jpeg.hpp>
void Bitmap2Jpeg(AnsiString bmpFile, AnsiString jpegFile)
{
Graphics::TBitmap *bitmap = new Graphics::TBitmap();
bitmap->LoadFromFile(bmpFile);
TJPEGImage *jpeg = new TJPEGImage();
try {
jpeg->Assign(bitmap);
jpeg->SaveToFile(jpegFile);
}
__finally {
delete jpeg;
}
delete bitmap;
}

void Jpeg2Bitmap(AnsiString jpegFile, AnsiString bmpFile)
{
Graphics::TBitmap *bmp = new Graphics::TBitmap();
TJPEGImage *jpeg = new TJPEGImage();
jpeg->LoadFromFile(jpegFile);
bmp->Assign(jpeg);
bmp->SaveToFile(bmpFile);
delete jpeg;
delete bmp;
}
