Greetings to all, a question, would it be possible in BASIC to print an image using GET and PUT with a transparent color? |

A note: using console,,4 you can make put/get work like XOR masks (there are also other values to work with "OR" and "AND" modes on TO8/TO9+), therefore it should, theorically, be possible do achieve something. |

Not using Put and Get basic function but if you use the 16c bm mode, you can decide to use one byte as a transparent color (among the 15) for instance the "15" color with (in Pascal): if color[i]<>15 pset (X,Y, color[i]); It's as the GIF standard, in which you chose a transparent color. |
