Bug #17955 Updated: GD and unicode maps/webdings

ID: 17955 Updated by: markonen@php.net Reported By: dk@webcluster.at -Status: Bogus +Status: Open Bug Type: GD related Operating System: RedHat 7.3 PHP Version: 4.2.1 New Comment: No, this is in fact ours (all the relevant code is in gdttf.c). Previous Comments: ------------------------------------------------------------------------ [2002-07-02 21:44:59] sniper@php.net So it's obviously not any bug in PHP. ------------------------------------------------------------------------ [2002-06-25 05:44:46] dk@webcluster.at Additional info: I talked again to the freetype guys. They asked me to try to use "&#61473;" instead of the characters. This worked fine: <quote> If &#61473; works but UTF-8 not then GD was compiled with the option JISX0208 which IMHO prevents decoding of UTF-8 encoded character codes. Then try to find out why this option was set. </quote> ------------------------------------------------------------------------ [2002-06-24 21:25:51] dk@webcluster.at <?PHP function hex2rgb($hex) { $c = array('R', 'G', 'B'); $i = 0; preg_replace('/([a-f0-9]{2})/ie', '$rgb[$c[$i++]] = hexdec("\1")', $hex); return $rgb; } $col = "FF0000"; $text = "Here comes the text!"; $rgb = hex2rgb($col); $fontsize = 18; $font="/some/dir/webdings.ttf"; $size=ImageTTFBBox($fontsize,0,$font,$text); $width = abs($size[2]); $height = abs($size[5]); Header ("Content-type: image/jpeg"); $im = ImageCreate ($width+11, $height+8); $bg = ImageColorAllocate ($im, 255, 255, 255); ImageColorTransparent($im, $bg); $main = ImageColorAllocate ($im, $rgb["R"], $rgb["G"], $rgb["B"]); $shadow = ImageColorAllocate ($im, 219, 219, 219); ImageTTFText($im,$fontsize,0,1,21,$shadow,$font,$text); ImageTTFText($im,$fontsize,0,0,20,$main,$font,$text); ImageGif ($im); ImageDestroy ($im); ?> ------------------------------------------------------------------------ [2002-06-24 18:54:50] sniper@php.net Being the lazy asses we are, could you add some short example script which shows what doesn't work? --Jani ------------------------------------------------------------------------ [2002-06-24 16:03:49] dk@webcluster.at Hello, I want to output the webdings.ttf font using freetype and gd. Unfortunately I only get rectangular symbols back. I discusse the issue inside the freetype mailing list and they told me that "FreeType2 selects a Unicode charmap as default charmap for a font if available. Webdings.ttf does not have a Unicode charmap." They thought that it could be a bug in gd and supplied a patch for gdlib. _-_-_quote_-_-_ ----8<---- for (n = 0; n < a->face->num_charmaps; n++) { charmap = a->face->charmaps[n]; platform = charmap->platform_id; encoding = charmap->encoding_id; if ((platform == 3 && encoding == 1) /* Windows Unicode */ || (platform == 3 && encoding == 0) /* Windows Symbol */ || (platform == 2 && encoding == 1) /* ISO Unicode */ || (platform == 0)) { /* Apple Unicode */ a->have_char_map_unicode = 1; found = charmap; ----8<---- So it would work if GD would not forget to tell FreeType2 to use the charmap it found... : ----8<---- --- gd-2.0.1/gdft.c.ori Tue Apr 3 20:44:42 2001 +++ gd-2.0.1/gdft.c Mon Jun 24 16:25:35 2002 @@ -445,6 +445,12 @@ *error = "Unable to find a CharMap that I can handle"; return NULL; } + err = FT_Set_Charmap (a->face, found); + if (err) + { + *error = "Could not set CharMap"; + return NULL; + } return (void *) a; } ----8<---- _-_-_quote_-_-_ I applied it, but it still doesn't seem to work. I'm sure that the right gd is linked (ldd). I've seen examples with Zapf Dingbats and Webdings work with other languages, so I think it may be also a php issue. Maybe you could point me on a solution.
