Verified that the problem still exists in PHP 4.3.0RC1. Previous Comments: ------------------------------------------------------------------------ [2002-11-16 13:44:42] [EMAIL PROTECTED] Reopening the report ------------------------------------------------------------------------ [2002-11-15 23:06:10] [EMAIL PROTECTED] I forgot to mention that I use t1lib 1.3.1 from the following address to enable the imageps* functions in the gd extension (--with-t1lib configure option): ftp://sunsite.unc.edu/pub/Linux/libs/graphics/t1lib-1.3.1.tar.gz ------------------------------------------------------------------------ [2002-11-15 23:03:00] [EMAIL PROTECTED] Yes, certainly, here's the whole code and the font in question: http://web.axelero.hu/fdsoft/temp/fonttest.zip There are some really ugly calculations and a brute force way of determining the size of the would-be image in the code, since imagepsbbox function didn't quite work well either. At least that was the case with PHP 4.2.x, and since I added this workaround, I've yet to re-check that in 4.3.0. Now for this weird output problem I can't figure out a workaround, and this was absolutely perfect with PHP 4.2.x., hence my bug report. It's likely that the fonts I use are of low quality or buggy or both; but that doesn't change the fact that this was working nicely with the older versions. Thanks ------------------------------------------------------------------------ [2002-11-15 21:18:24] [EMAIL PROTECTED] Can you please provide a complete and working example script? This one you added does not work. --Jani ------------------------------------------------------------------------ [2002-11-15 17:08:45] [EMAIL PROTECTED] I use the GD extension to generate .png images automatically for displaying text with a specific Type1 font, using the imagepstext function. PHP 4.2.x generates these images perfectly, while using PHP 4.3.0-pre1 and -pre2 results in some really weird output. Here are some examples to show the difference: http://web.axelero.hu/fdsoft/temp/images.html There actually seems to be two seperate problems: - the characters are not lined up properly any more - anti-aliasing produces weird output (most pronounced when the resulting image is viewed in IE 6, less ugly but still noticeable in Mozilla) The anti-aliasing problem pretty much goes away if I recompile PHP 4.3.0-pre2 to use my old GD 1.8.4 (from the Red Hat rpms) instead of PHP's built-in version of GD. The php code in question: <code> $fonthandle=@imagepsloadfont(FONT_PATH.$font); imagepsencodefont($fonthandle, FONT_PATH.'IsoLatin1.enc'); $im = imagecreate($imgwidth, $imgheight); $background_color = imagecolorallocate ($im, $background[0], $background[1], $background[2]); imagecolortransparent($im, $background_color); $text_color = imagecolorallocate ($im, $color[0], $color[1], $color[2]); imagepstext($im, $txt, $fonthandle, $size, $text_color, $background_color,$x, $y, 0, 0, 0, 16); imagepng($im); </code> Finally my php configure options: <code> --host=i686-pc-linux-gnu --build=i686-pc-linux-gnu --target=i386-redhat-linux-gnu --program-prefix= --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/usr/com --mandir=/usr/share/man --infodir=/usr/share/info --prefix=/usr --with-config-file-path=/etc --with-exec-dir=/usr/bin --enable-force-cgi-redirect --disable-debug --enable-dbg=shared --with-dbg-profiler --enable-pic --disable-rpath --enable-inline-optimization --with-bz2 --with-db3 --with-curl=/usr/local --with-freetype-dir=/usr --with-png-dir=/usr --with-gd=shared --enable-gd-native-ttf --with-ttf --with-t1lib --with-gettext=shared --with-ncurses --with-iconv=shared --with-jpeg-dir=/usr --with-openssl --with-png --with-regex=system --with-expat-dir=/usr --with-zlib --with-layout=GNU --enable-bcmath --enable-exif --enable-ftp --enable-sockets --enable-sysvsem --enable-sysvshm --enable-discard-path --enable-track-vars --enable-trans-sid --enable-wddx --enable-exif --enable-memory-limit --enable-bcmath --enable-shmop --enable-versioning --enable-calendar --enable-dbx --enable-dio --enable-mcal --with-readline --with-mysql=shared,/usr --with-sybase-ct=shared,/usr/local --with-pgsql=shared --with-unixODBC=shared --with-interbase=shared,/opt/interbase --with-imap=shared --with-imap-ssl --with-kerberos=/usr/kerberos --with-zip=shared --with-pspell=shared --with-ming=shared --with-pdflib=shared --with-pear=/usr/share/pear --with-apxs=/usr/sbin/apxs </code> The '--with-gd=shared' option was changed to '--with-gd=shared,/usr' to produce the "without built-in GD" output. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=20451&edit=1
