finaly I did it this way : (pasted at the end of the mail)
But the problem is the result is very dirty,
considering the result with other way to do this.
top-left is the image in XPM-format
top-right is the image in PNG-format
bottom-left is a classic php-gtk-script displaying an XPM image
bottom-right is the php-script below loading and displaying a PNG img
Why is the result so bad ?
=======================================
<?php
if ( !extension_loaded( 'gtk' ) )
strstr( PHP_OS, 'Linux' ) ? dl('php_gtk.so') : dl('php_gtk.dll');
$handle = imagick_readimage( 'images/img.1.png' );
if ( imagick_iserror( $handle ) ) {
$reason = imagick_failedreason( $handle );
$description = imagick_faileddescription( $handle );
print "handle failed!\nReason: $reason\nDescription:
$description\n";
exit;
}
imagick_convert( $handle, 'XPM' );
if ( !( $image_data = imagick_image2blob( $handle ) ) ) {
$reason = imagick_failedreason( $handle );
$description = imagick_faileddescription( $handle );
print "imagick_image2blob() failed\nReason: $reason\nDescription:
