This is a follow-up on bug 20839.

The XPM format is now supported in the GD extension :)

I have noticed that some XPM icons are not properly converted to PNG.

My analysis of the problem is that when the color definition is :

static char * XPM_icon[] = {
/* width height ncolors cpp [x_hot y_hot] */
"32 32 9 1 -1 -1",
/* colors */
"       c #DEDEDFDFDEDE",
".      c #212120202121",
"X      c #737371717373",
"o      s iconColor1    m black c black",
"O      s iconColor6    m white c yellow",
"+      s iconColor4    m white c green",
"@      c #ADADAEAEADAD",
"#      c #636361616363",
"$      s iconColor3    m black c red",
/* pixels */
...

the color conversion is not right.
I do not know if it is GD or the use of GD in PHP that is not doing the right work.

But if you have the color definition like :

static char * XPM_icon[] = {
/* width height ncolors cpp [x_hot y_hot] */
"32 32 9 1 -1 -1",
/* colors */
"       c #DEDEDFDFDEDE",
".      c #212120202121",
"X      c #737371717373",
"o      c #000000000000",
"O      c #FFFFFFFF0000",
"+      c #0000FFFF0000",
"@      c #ADADAEAEADAD",
"#      c #636361616363",
"$      c #FFFF00000000",
/* pixels */
...

everything is fine.

Hope this will help make gd extension better.

Here are 2 XPMs.
