FreeImage_SaveBMP

bool FreeImage_SaveBMP(void *dib, const char *filename, BMPFlags flags = BMP_DEFAULT);

Saves the FreeImage DIB to a Windows Bitmap file. The BMP file is always saved in the Windows format. No compression is used.

void *dib = FreeImage_LoadBMP("test.bmp");

if (dib != NULL) {
FreeImage_SaveBMP("saved.bmp");
FreeImage_Free(dib);
}

FreeImage_SavePNG

bool FreeImage_SavePNG(void *dib, const char *filename, PNGFlags flags = PNG_DEFAULT);

Saves the FreeImage DIB to a PNG file.

void *dib = FreeImage_LoadBMP("test.bmp");

if (dib != NULL) {
FreeImage_SavePNG("saved.png");
FreeImage_Free(dib);
}

FreeImage_SavePNM

bool FreeImage_SavePNM(void *dib, const char *filename, PNMFlags flags = PNM_DEFAULT);

Saves the FreeImage DIB to a PNM file. PNM is a descriptive name for a collection of ASCII based bitmap types: PBM, PGM and PPM. If the bitmap has a bitdepth of 1, the file is saved as a PBM file. If the bitmap has a bitdepth of 8, the file is saved as a PGM file. If the bitmap has a bitdepth of 24, the file is saved as a PPM file. Other bitdepths are not supported.

void *dib = FreeImage_LoadBMP("test.bmp");
if (dib != NULL) {
switch(FreeImage_GetBPP(dib)) {
case 1 :
FreeImage_SavePNM("saved.pbm");
break;
case 8 :
FreeImage_SavePNM("saved.pgm");
break;
case 24 :
FreeImage_SavePNM("saved.ppm");
break;
}

FreeImage_Free(dib);
}

FreeImage_SaveTIFF

bool FreeImage_SaveTIFF(void *dib, const char *filename, TIFFFlags flags = TIFF_DEFAULT);

Saves the FreeImage DIB to a TIFF file.

void *dib = FreeImage_LoadBMP("test.bmp");

if (dib != NULL) {
FreeImage_SaveTIFF("saved.tiff");
FreeImage_Free(dib);
}
