static int getPNMinteger ( FILE * fp ) [static]

Read an integer value form the header of a PNM (PBM, PGM, PPM) file header (or body for P1-P3). Skips any white space and comments, then reads a sequence of digits.

Parameters:

[in] fp File pointer to read from

Returns:: returns the integer value of the number read.

Precondition:: fp points somwhere were the next integer is expected

Postcondition:: character right behind the last digit was consumed by getc(), or end-of-file was reached.

static void skipPNMcomment ( FILE * fp ) [static]

Skip comments in a PNM (PBM, PGM, PPM) file header (or body for P1-P3). Reads and discards characters from a file pointer until end-of-line or and-of-file is reached.

Parameters:

[in] fp File pointer to read from

Precondition:: comment char '#' was just read before with getc(fp)

Postcondition:: newline char of this comment was read as last character or end-of-file was reached.
