-
MAllocImage
- Creates an image of size 'img_w' x 'img_h' with a color depth
of 'nplanes'
-
MReadBMPFile
- Creates an image using the data in the BMP file named 'fname'
-
MReadTIFFFile
- Creates an image using the data in the TIFF file named 'fname'
-
MReadJPEGFile
- Creates an image using the data in the JPEG file named 'fname'
-
MReadGIFFile
- Creates an image using the data in the GIF file named 'fname'
-
MWriteTIFFFile
- Writes the image 'img' to a file named 'name' in tiff format
-
MWriteBMPFile
- Writes the image 'img' to a file named 'name' in BMP format
-
MWriteJPEGFile
- Writes the image 'img' to a file named 'name' in tiff format
-
void MFreeImage(MIMAGE data)
- Frees an image by deallocating all used colors and memory
-
void MInstallImage(MIMAGE data)
- Allocates all colors required by the image and makes it ready to
be drawn
-
MUninstallImage
- Deallocates image colors and frees internal resources
-
void MImageGetInfo(MIMAGE pmi, int *pw, int *ph, int *pnplanes)
- Returns image size and color depth in the integers pointed to by
'pw', 'ph' and pnplanes'
-
MImageGetPixelRGB
- Returns in the integers pointed to by 'pr', 'pg', 'pb'
the R-G-B values of the pixel at location ('x','y') in the
image 'pmi'
-
MImageSetPixelRGB
- Sets the R-G-B components of the pixel at location ('x','y') in the
image 'pmi' with the values in the parameter 'r', 'g', 'b'
-
MImageGetPixelIndex
- Returns the index in the colormap corresponding to the image pixel
at location ('x','y')
-
MImageSetPixelIndex
- Sets the color of the pixel at location ('x','y') in image 'img'
with R-G-B values of the image's colormap entry 'i'
-
MImageGetCMapEntry
- Returns in the integers pointed to by 'pr, 'pg', 'pb' the R-G-B
values of the image's colormap entry 'i'
-
MImageSetCMapEntry
- Stores the R-G-B value formed by 'r, 'g', 'b' in the image's
colormap entry 'i'
