You can download the image bottone1.png by the url http://www.i-dome.com/microtools/bottoni/bottone01.png and the font BOOMBOX.TTF by url http://www.i-dome.com/microtools/fonts/BOOMBOX.TTF The program must run with this parameters: testo=the text larghezza=the width (default 96 pix) The program run correctly on version 4.2.3 of PHP with gd2.0.4. Also it runs correctly when I give the parameter "larghezza" (with) at the original image width (96).

This line: $tc = ImageColorAllocate ($im, $colors[$color][0], $colors[$color][1], $colors[$color][2]); can be your problem. Check the $color array, or set error_reporting(E_ALL); to see if they are initialized correctly (btw, use always this flag to develop). Second point, ImageAlphaBlending is useless in your case, ImageColorAllocate allocates a color with an opaque alpha channel. thank's for your interest, pierre ------------------------------------------------------------------------ [2003-01-19 07:27:08] paolo at i-dome dot com Don't show the text also with the latest CVS version. ------------------------------------------------------------------------ [2003-01-18 13:17:24] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2003-01-18 11:17:51] paolo at i-dome dot com This code work fine on PHP 4.2.3 compiled with gd2.0.4, but give a image without text with php 4.3 compiled with internal gd support. I have this problem only in the image resized and not with the original image: if($width==$isize[0]) //original size: this work { $im = ImageCreateFromPNG ("bottoni/".$tipo_bottone); } else // to resize: don't work { $im1 = ImageCreateFromPNG("bottoni/".$tipo_bottone); $im=ImageCreateTrueColor($width, $isize[1]); ImageCopy($im, im1,0,0,0,0,$margin_width,$isize[1]); ImageCopyResized($im, $im1, $margin_width, 0, $margin_width, 0, $width, $isize[1], round($isize[0]-($margin_width * 2),0), $isize[1]); ImageCopy($im, $im1,$margin_width+$width-1,0,$isize[0]-$margin_width,0,$margin_width,$isize[1]); ImageDestroy($im1); } ImageAlphaBlending($im, true); $tc = ImageColorAllocate ($im, $colors[$color][0], $colors[$color][1], $colors[$color][2]); imagettftext($im, $size, 0, $center, $margin_height, $tc, $currpath."/fonts/".$font,$testo); ImageAlphaBlending($im, false); header("Content-Type: image/png\n\n"); ImagePNG($im); Thank for support Paolo Morandi ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21729&edit=1
