Nikos Alexandris:
if (chroma == 0.0) {saturation = 0.0; /* undefined -- (how to) set to NULL? */ hue = 0.0;
I'd like to set hue to NULL, whenever the condition is met. How do I do that?
Markus Neteler:
Something like: for (row = 0; row < nrows; row++) { G_percent(row, nrows, 5); for (col = 0; col < ncols; col++) { cell_buf[col] = bas[SEG_INDEX(ba_seg, row, col)]; if (cell_buf[col] == 0)Rast_set_null_value(&cell_buf[col], 1, CELL_TYPE);Alright, that is: anything that `&cell_buf[col]` points to, set the number of values `1` to NULL.
