Don't know about Jake, but I suggest you use Gimp. |
47 |
|
48 |
Gimp is ideal for creating icon files (as in ico file type) although I am not |
49 |
sure that's what you're talking about. If converting an RGB file to b&w is a |
50 |
problem, you could try desaturating the image while in RGB and then |
51 |
converting it to index mode. It is always better to work on an RGB file and |
52 |
then convert it to Index mode when the image is complete. If the icon image |
53 |
is displaying lines when rendered, I suspect the image is distorting due to |
54 |
incorrect width and height settings in the conversion code, or the icon image |
55 |
has not been created with the correct height and width for the default |
56 |
settings of an icon file (ie: 16x16 px or 32x32 px). |
