3 June 2010 3:57:22.866 PM PGMA_IO_PRB FORTRAN90 version Test the PGMA_IO ASCII portable grayscale routines. TEST01 PGMA_EXAMPLE sets up sample PGM data. PGMA_WRITE writes an ASCII PGM file. Wrote the header and data for "pgma_io_prb_01.ascii.pgm". Number of rows of data = 300 Number of columns of data = 300 TEST02 PGMA_READ reads an ASCII PGM file. PGMA_WRITE_TEST created some data. PGMA_READ_HEADER read the header. Number of rows of data = 300 Number of columns of data = 300 Maximum G value = 79 PGMA_READ_DATA read the data. Sample data: 1 1 60 34 34 73 67 67 34 100 100 45 133 133 60 167 167 20 200 200 32 233 233 46 266 266 7 300 300 19 The data was accepted by PGMA_CHECK_DATA. TEST03 PGMA_WRITE writes an ASCII PGM file. In this example, we make a sort of grayscale checkerboard. Wrote the header and data for "pgma_io_prb_03.ascii.pgm". Number of rows of data = 300 Number of columns of data = 300 PGMA_IO_PRB Normal end of execution. 3 June 2010 3:57:23.332 PM
