5 | ; Here, when vargrid is not 'T' or 'W', we have to |
---|
6 | ; recuperate tmask, glamt, gphit and the array of triangulation on the |
---|
7 | ; considered sub-domain for the drawing. |
---|
8 | ; The specificity of decoupeterre, in comparaison with <pro>grille</pro>, is |
---|
9 | ; that we take, if possible, a sub-domain just a little bit bigger than the |
---|
10 | ; one defined by <pro>domdef</pro> in order to be |
---|
11 | ; sure that the mask we draw will cover over all the drawing. |
