how to transform the transparency into a precise colour
Posted: 2010-06-09T03:39:32-07:00
Short presentation :
I'm using imagemagick since few years, but i think i'm still a beginner, i'm still discovering something, and i'm still in need of something new, and there are always so many ways to do it, that's just incredible !
And I adore too the command line ! It makes me think to my beloved computers : Oric, Amiga, old 386 with Ms-dos, the old time, the good souvenirs ...
Anyway, my question :
I like the operator -transparent, but i would like to make just the inverse, to change the transparency (1-255) into a defined color.
I've tried many things but i found nothing, i've tried with '-transparent-color' option and a GIF but without success.
I've tried also to manipulate the channel Alpha, with '-alpha' options, but i have'nt got no result.
I suppose there's a solution or certainly many, but I 've got not enough experience.
Does someone have an idea ?
Thanks for everything.
