pppm2pan

Converts PPM (Portable PixMap), PGM (Portable GrayMap) ou PBM (Portable BitMap) image file to Pandore file.

pppm2pan im_in [im_out|-]

pppm2pan converts a PPM (Portable PixMap image), PGM (Portable GrayMap image), or PBM (Portable BitMap image) to Pandore image file.

A PPM, PGM, PBM consists of the followings:

The first line contains the "magic number" among:
- P2: for binary image with ASCII data.
- P2: for gray scale image with ASCII data.
- P4: for binary image with pure binary data.
- P5: for gray scale image with pure binary data.
- P3: for color image with ASCII data.
- P6: for color image with pure binary data.
The second line contains the number of columns and rows in ASCII.
The third line contains the number of colors.
Each line can include comments introduced by #.
The data format depends on the magic number: (Caution: No line should be longer than 70 characters.)
- P1: pixel is represented as an ASCII decimal number (0: while, 1:black).
- P2: pixel is represented as an ASCII decimal number.
- P5: pixel is represented as 1 bit (0: while, 1: black).
- P5: pixel is represented as 1 byte.
- P3: pixel is represented as a triplet of ASCII decimal number (Red, Green Blue).
- P6: pixel is represented as a triplet of bytes (Red, Green Blue).

Examples:

P2
#Gray scale image
#with 5 columns and 5 rows.
5 4
255
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

Tip: PPM image can be easily built by hand. This is a convenient way to build image from scratch.

Returns SUCCESS or FAILURE.

Convert ppm image into pandore image, then display it:

   pppm2pan image.ppm image.pan
   pvisu image.pan

Errc PPPM2Pan( const char* filename, Pobject **obj_out );
