ID: 19133 Updated by: rasmus@php.net Reported By: dhunter@ssesco.com -Status: Open +Status: Closed Bug Type: GD related Operating System: Win2K PHP Version: 4.2.2 New Comment: I verified that this works correctly in the bundled GD2 in PHP 4.3. Previous Comments: ------------------------------------------------------------------------ [2002-08-29 16:32:16] dhunter@ssesco.com Sorry, we have to stick with version 4.2.2 for now. Can anyone think of any possible workarounds? ------------------------------------------------------------------------ [2002-08-28 13:57:34] sander@php.net This might be fixed with the bundled verion of GD2 available with 4.3.0. Please try a snapshot from http://snaps.php.net. ------------------------------------------------------------------------ [2002-08-28 13:02:59] dhunter@ssesco.com Sample script: <?php $Png0 = "c:\\thumbs\\TERRAIN_color_big.PNG"; $Png1 = "c:\\thumbs\\Z00_LYR3_MAP_T_STATES_CYAN.png"; $Png2 = "c:\\thumbs\\eta_big.png"; $Timg= "c:\\thumbs\\test.png"; $Tim0= ImageCreateFromPng($Png0); $Tim1= ImageCreateFromPng($Png1); $Tim2= ImageCreateFromPng($Png2); ImageCopyMerge($Tim0,$Tim1,0,0,0,0,649,548,100); ImageDestroy($Tim1); ImageCopyMerge($Tim0,$Tim2,0,0,0,0,649,548,100); ImageDestroy($Tim2); ImagePng($Tim0,$Timg); ImageDestroy($Tim0); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <STYLE><!-- .LYR0 {position: absolute; TOP:800; LEFT:10;z-Index:0; } .LYR1 {position: absolute; TOP:800; LEFT:10;z-Index:1; } .LYR2 {position: absolute; TOP:800; LEFT:10;z-Index:2; } --></style> </head> <body> <!-- display the composite image --> <img src=<?php echo "$Timg"; ?>><br><br> <!-- for comparison, display the PNGs layered atop one another --> <span class=LYR0><img src=<?php echo "$Png0"; ?>></span> <span class=LYR1><img src=<?php echo "$Png1"; ?>></span> <span class=LYR2><img src=<?php echo "$Png2"; ?>></span> </body> </html> Note that with php_gd2, the composite image "$Timg" ends up identical to $Png3. With php_gd, it looks identical to the three PNGs layered atop one another using CSS (which is what I believe to be the proper behavior). ------------------------------------------------------------------------ [2002-08-28 12:27:46] kalowsky@php.net sample script? ------------------------------------------------------------------------ [2002-08-28 11:11:31] dhunter@ssesco.com Same behavior for PHP versions 4.1.2 and 4.2.2 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
