Replace colors in imageData under linux doesn't work

[Ludovic Thébault]

Hello,

I've made a map wih several sectors. Each sector have a specific color.
For example sector one have this color : 245, 255, 255
sector two : 215,255,255
sector three : 194,255,255
...
The map appear in blue (each sector with a different blue)

Under MacOS and Windows, a script replace the color of a sector with an other. But under linux (Ubuntu, Mandriva, Xubuntu) it doesn't work. I've tested with Rev Studio 2.91 and RevMedia 4.

the script :
 get the imageData of image "carte" 

replace (numToChar(0) & numtochar(230) & numtochar(255) & numtochar(255)) with \
        (numToChar(0) & numtochar(45) & numtochar(155) & numtochar(90)) in it
     
Under Linux, my map appear yellow !

Here, a screenshot with the original map, the new map under MacOS and under Linux
