Re: Please, i need use images in php-gtk...

You cand use gdkpixbuf to render non xpm images in PHP-GTK, but this widget is not for Windows, so you can use Nathan code: This is a script <?php $file = "path to your image file a gif for this example"; if(! $img = imagecreatefromgif($file)) echo "can't load the image $file\n"; $xpm_d = image2xpm_d($img);//there's a file convertion function too imagedestroy($img);//don't forget this one $pix = Gdk::pixmap_create_from_xpm_d($gdkwindow, null, $xpm_d); $pixmapwid = &new GtkPixmap($pix[0], $pix[1]); //and then do what you want and be happy ?> This is the "library" <?php /** * function set for image manipulation * @author Jonathan Gotti <nathan@the-ring.homelinux.net> * @copyright &copy; 2004 Jonathan Gotti * @category images * @license http://opensource.org/licenses/lgpl-license.php GNU Lesser General Public Licence */ /** * get the palette * @author jonathan.gotti@free.fr * @date 2003-12-20 * @param ressource image $img * @return array */ function imagegetpalette($img){ $width = imagesx($img); $height= imagesy($img); for($i=0;$i<imagecolorstotal($img);$i++){ $colors[$i]=imagecolorsforindex($img,$i); } return $colors; } /** * get a xpm style palette from a gd one * @author jonathan.gotti@free.fr * @date 2003-12-20 * @param array $gdpalette * @param string $indexed_type 'gd' keep the gd_index,'xpm' indexed by xpm char code * @param string $value_type 'char_code' the xpm char code index, 'color' the xpm color value,'both' associated value is are array containing xpm char code and xpm color value *@param array $trans array of transparent color values * @return array */ function gd2xpmpalette($gdpalette,$indexed_type='xpm',$value_type='color'){ $nb_colors = count($gdpalette); //initialize char array if needed if($indexed_type=='xpm' || $value_type != 'color'){ $first_char = 48;//lowest used ASCII char code $last_char = 126;//highest used ASCII char code //Thanks to my friend RHONONO for the next line $nb_char= intval(log($nb_colors)/log($last_char-$first_char)) +1; for($i=0;$i<=$nb_char;$i++){//initialize array of char $chars[$i]=$first_char; } } foreach($gdpalette as $gdindex => $gdcolor){ //recompose xpm character coding only if needed if($indexed_type=='xpm' || $value_type!='color'){ $char_code = null;//initialise char_code for($i=0;$i<$nb_char;$i++){//increment other chars $chars[0]++;//increment chars if($chars[$i]>$last_char){//check chars are in the good range $chars[$i]=$first_char; $chars[$i+1]++; } $char_code = chr($chars[$i]) . $char_code ; } } if($indexed_type == 'xpm')//choose indexed type $outindex = $char_code; else//assume gd indexed wanted $outindex = $gdindex; //the val according to it switch($value_type){ case 'color': if($gdcolor['alpha']>=127)//keep transparent on palette image $out[$outindex] = 'None'; else $out[$outindex] = strtoupper('#'. zero_fill(dechex($gdcolor['red']),2). zero_fill(dechex($gdcolor['green']),2). zero_fill(dechex($gdcolor['blue']),2)); break; case 'char_code': $out[$outindex] = $char_code; break; case 'both': if($gdcolor['alpha']>=127)//keep transparent on palette image $out[$outindex] = array(0=>$char_code,1=>'None'); else $out[$outindex] = array( 0=>$char_code, 1=>strtoupper('#'.zero_fill(dechex($gdcolor['red']),2). zero_fill(dechex($gdcolor['green']),2). zero_fill(dechex($gdcolor['blue']),2))); break; } } return $out; } /** * get xpm_data from gd image resource * @author jonathan.gotti@free.fr * @date 2003-12-20 * @param resource gd image $img * @return xpm data */ function image2xpm_d($img,$trans=TRUE){ $w = imagesx($img); $h = imagesy($img); //the first case is only for PNG with indexed palette if(imageistruecolor($img) && $trans){ //create an indexed palette copy of $img //after various test best results are the 3 next lines //could be fine to have a better way $imgtmp = imagecreatetruecolor($w,$h); imagecopymerge($imgtmp,$img,0,0,0,0,$w,$h,100); imagetruecolortopalette($imgtmp,TRUE,255);//keep an index for trans //set the trans color to a known one $transindex = imagecolorallocate($imgtmp,1,1,1); $transindex = imagecolortransparent($imgtmp,$transindex); //get all palette information needed $gdpalette = imagegetpalette($imgtmp); $palette = gd2xpmpalette($gdpalette,'gd','both'); //image definition list($color0k,$color0v )= each($palette); $xpm_d[0]= "$w $h ".count($palette)."
