I have searched everywhere to find a possible solution to my problem. Unfortunately I cannot seem to figure it out. I have a .php file that creates an image based on other images. I had the script working exactly as it is right now before without flaws. But after fiddling around with some other files it suddenly stopped working and is generating corrupt .png images now on Firefox, Chrome and IE.
image.php
<?php
ini_set("display_errors", 1);
ini_set("error_reporting", 2047);
ini_set("display_errors", 1);
ini_set("display_startup_errors", 1);
error_reporting("E_ALL");
include("GameEngine/Database.php");
if(isset($_GET['uid'])){
$uid = $_GET['uid'];
} else {
$uid = "1";
}
if(isset($_GET['size'])){
if($_GET['size']=='profile'){
$size = '31x40';
}elseif($_GET['size']=='inventory'){
$size = '64x82';
}elseif($_GET['size']=='sideinfo'){
$size = '119x136';
}
} else {
$size = "119x136";
}
$herodetail = $database->HeroFace($uid);
if($herodetail['color']==0){
$color = "black";
}
if($herodetail['color']==1){
$color = "brown";
}
if($herodetail['color']==2){
$color = "darkbrown";
}
if($herodetail['color']==3){
$color = "yellow";
}
if($herodetail['color']==4){
$color = "red";
}
$geteye = $herodetail['eye'];
$geteyebrow = $herodetail['eyebrow'];
$getnose = $herodetail['nose'];
$getear = $herodetail['ear'];
$getmouth = $herodetail['mouth'];
$getbeard = $herodetail['beard'];
$gethair = $herodetail['hair'];
$getface = $herodetail['face'];
// USAGE EXAMPLE:
$body = imagecreatefrompng('img/hero/head/'.$size.'/face0.png');
if($getbeard!=5){
$beard = imagecreatefrompng('img/hero/head/'.$size.'/beard/beard'.$getbeard.'-'.$color.'.png');
}
$ear = imagecreatefrompng('img/hero/head/'.$size.'/ear/ear'.$getear.'.png');
$eye = imagecreatefrompng('img/hero/head/'.$size.'/eye/eye'.$geteye.'.png');
$eyebrow = imagecreatefrompng('img/hero/head/'.$size.'/eyebrow/eyebrow'.$geteyebrow.'-'.$color.'.png');
if($gethair!=5){
$hair = imagecreatefrompng('img/hero/head/'.$size.'/hair/hair'.$gethair.'-'.$color.'.png');
}
$mouth = imagecreatefrompng('img/hero/head/'.$size.'/mouth/mouth'.$getmouth.'.png');
$nose = imagecreatefrompng('img/hero/head/'.$size.'/nose/nose'.$getnose.'.png');
$face = imagecreatefrompng('img/hero/head/'.$size.'/face/face'.$getface.'.png');
// SAME COMMANDS:
$database->imagecopymerge_alpha($body, $face, 0, 0, 0, 0, imagesx($face), imagesy($face),100);
$database->imagecopymerge_alpha($body, $ear, 0, 0, 0, 0, imagesx($ear), imagesy($ear),100);
$database->imagecopymerge_alpha($body, $eye, 0, 0, 0, 0, imagesx($eye), imagesy($eye),100);
$database->imagecopymerge_alpha($body, $eyebrow, 0, 0, 0, 0, imagesx($eyebrow), imagesy($eyebrow),100);
if($gethair!=5){
$database->imagecopymerge_alpha($body, $hair, 0, 0, 0, 0, imagesx($hair), imagesy($hair),100);
}
$database->imagecopymerge_alpha($body, $mouth, 0, 0, 0, 0, imagesx($mouth), imagesy($mouth),100);
$database->imagecopymerge_alpha($body, $nose, 0, 0, 0, 0, imagesx($nose), imagesy($nose),100);
if($getbeard!=5){
$database->imagecopymerge_alpha($body, $beard, 0, 0, 0, 0, imagesx($beard), imagesy($beard),100);
}
// OUTPUT IMAGE:
header("Content-Type: image/png");
imagesavealpha($body, true);
imagepng($body, NULL);
?>
I have tried commenting out the header() so that I can check if there is an error in any of the PHP before the image gets rendered. This is not the case. I have tried all $variables in an tag to check if these rendered properly. They did. I am at a loss as to what the problem could be.
My only guess right now is that there is a whitespace or carriage return which somehow gets added to the final render causing it to corrupt. However, I have searched for this possible whitespace for ages and cannot seem find it.
Any tips and/or suggestions are extremely appreciated!
SOLVED One of the files this script was including was saved as UTF-8 with BOM. This gave the image an extra byte making it corrupt. Saving all the files as UTF-8 without BOM fixed my problem.
