Что я уже пробовал:
У меня есть эта функция, но не знаю как справиться с этим в image.php
function IsTransparentPng($File){
//32-bit pngs
//4 checks for greyscale + alpha and RGB + alpha
if ((ord(file_get_contents($File, false, null, 25, 1)) & 4)>0){
return true;
}
//8 bit pngs
$fd=fopen($File, 'r');
$continue=true;
$plte=false;
$trns=false;
$idat=false;
while($continue===true){
$continue=false;
$line=fread($fd, 1024);
if ($plte===false){
$plte=(stripos($line, 'PLTE')!==false);
}
if ($trns===false){
$trns=(stripos($line, 'tRNS')!==false);
}
if ($idat===false){
$idat=(stripos($line, 'IDAT')!==false);
}
if ($idat===false and !($plte===true and $trns===true)){
$continue=true;
}
}
fclose($fd);
return ($plte===true and $trns===true);
}
