[Resolved] fapping imagecreatefromjpeg() problems!!!

[stevesweetland]

ok, i have a cobalt raq4 on my shelf, where i do all of my development work, before i upload a site.

i have this function

function resizeandstamp($imgfrom,$imgto,$width,$quality,$fontfile="",$text="",$textsize=8,$extra=""){
  $src_img = imagecreatefromjpeg($imgfrom);
  $src_width = imagesx($src_img);
  $src_height = imagesy($src_img);

  $dest_width = $width;
  $dest_ratio = $src_width / $width;
  $dest_height = ceil($src_height / $dest_ratio);

  $dst_thumb = imagecreatetruecolor($dest_width,$dest_height);

  imagecopyresampled($dst_thumb, $src_img, 0, 0, 0, 0, $dest_width, $dest_height, $src_width, $src_height);
  if ($text != "" && $fontfile != ""){
    $textcolor = imagecolorallocate($dst_thumb, 0xFF, 0xFF, 0xFF);
    $midshadowcolor = imagecolorallocate($dst_thumb, 0x33, 0x33, 0x33);
    $shadowcolor = imagecolorallocate($dst_thumb, 0x00, 0x00, 0x00);
    imagettftext ($dst_thumb, $textsize, 0, 5, $dest_height-2, $midshadowcolor, $fontfile, $text);
    imagettftext ($dst_thumb, $textsize, 0, 4, $dest_height-3, $shadowcolor, $fontfile, $text);
    imagettftext ($dst_thumb, $textsize, 0, 3, $dest_height-4, $textcolor, $fontfile, $text);
  };
  if ($extra == "greyscale") imagecopymerged($dst_thumb, $src_img, 0, 0, 0, 0, $dest_width, $dest_height, $dest_width, $dest_height);

  $newfile = $imgto;
  if (imagejpeg($dst_thumb, $newfile, $quality)){
    return "true";
  } else {
    return "false";
  };
  imagedestroy($dst_thumb);
  imagedestroy($src_img);

  unset($dest_width);
  unset($dest_height);
  unset($dest_ratio);
  unset($src_width);
  unset($src_height);
};

which works fine + dandy on the cobalt. if i upload it, i get that blanko error message (translated as an error document by the browser).

heres the code where i call it

  if (is_uploaded_file($fld_file)){
    $type = $fld_file_type;
    if ($type == "image/jpeg" || $type == "image/pjpeg"){
      $parts = explode(".",$fld_file_name);
      $time = gmmktime();
      $filename = $time.".".$parts[1];
      $mid = $time."_mid.".$parts[1];
      $thumb = $time."_thumb.".$parts[1];
      resizeandstamp($fld_file,$path."/uploads/$filename",450,85,$fontfile="",$text="",$textsize=8,$extra="");
      resizeandstamp($path."/uploads/$filename",$path."/uploads/$mid",200,70,$fontfile="",$text="",$textsize=8,$extra="");
      resizeandstamp($path."/uploads/$mid",$path."/uploads/$thumb",130,60,$fontfile="",$text="",$textsize=8,$extra="");
      $error = "The file was uploaded and resized successfully<br><br>";
    } else {
      $parts = explode(".",$fld_file_name);
      $time = gmmktime();
      $filename = $time.".".$parts[1];
      copy($fld_file,$path."/uploads/$filename");
    };

$db->query("INSERT INTO Media (VillaID, Filename, Mid, Thumb, Type, Size, DateTime) VALUES ('$fld_id','$filename','$mid','$thumb','".$type."','".$fld_file_size."','".gmmktime()."');");
  } else {
    $error = "The file did not upload...<br><br>";
  };
  $submit = "EDIT"; // ignore this

i resize 3 versions of the image, based on each other, but it doesnt even do the first one, it just dies.

any great ideas?

[drew010]

is gd installed on the server where it dies?
try
$src_img = imagecreatefromjpeg($imgfrom) or die("image create failed");

try doing that for every possible statement that can fail and see if it sheds some light on something.

[stevesweetland]

yep, it has gd...

gd
GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

ill try the suggestion

[drew010]

if you have gd then maybe the problem is writing to a file, perhaps on the live server you dont have proper permissions, depending on if you pay a webhost. in that case you can probably try
$fp = fopen("testfile.txt", "w+") or die("file not created");

[stevesweetland]

i have all the correct permissions. i can do file creating, can use the 'copy' function.

now, i can make the page error with actual error messages if i take out the 'imagecreatefromjpeg'.

im assuming, no, i know for fact that the problem is that function.

anyone else have problems with this?

[drew010]

all i can think of to test the function is use a really basic example

create a new script and try:

<?php

$img = imagecreatefromjpeg("http://us.i1.yimg.com/us.yimg.com/i/mntl/tr/05q1/img_trees.jpg") or die("image not created");

header("Content-Type: image/jpeg");
imagejpeg($img);
?>

i suppose if the image outputs fine the function imagecreat... isnt the problem, otherwise it is.  that image was just the first i can find but you may want to try with one stored locally too.

[stevesweetland]

right.

that works.

loading a few images locally, works.

loading up a 300k local image doesnt work.

we have our problem, im guessing its dying then, because of memory issues.

anything i can do?

[stevesweetland]

a 300k image works, if its 800x600.

a 100k image doesnt work, if its 1600x1400.

resolution seems to have an impact, please help anyone!!

[drew010]

if it is a memory issue try putting
ini_set("memory_limit", "64M");
at the top of the script.
by default its 8M so i dont think its got to do with the filesize and memory, unless that value was dropped by the host.
you may also want to try ini_set("max_execution_time", 0); although i reallly doubt thats the problem.

[stevesweetland]

you, are a flipping legend.

this fixed my problem completely, uploading larger dimension pictures works fine also.

thanks mate!
