PHP and GD seem to have trouble creating images from PNGs of type greyscale with alpha when using imagecreatefrompng() . The results are incredibly distorted. I was wondering if anyone knew of a way to test for the colour type in order to notify the user of the incompatibility? Example: Original Image: http://dl.dropbox.com/u/246391/Robin.png Resulting Image: http://dl.dropbox.com/u/246391/Robin_result.png Code: <?php $resource = imagecreatefrompng('./Robin.png'); header('Content-type: image/png'); imagepng($resource); imagedestroy($resource); Cheers, Aron David Jones The colour type of a PNG

I am running running a script which moves an uploaded file with move_uploaded_file() . I have done this thousands of times but for some reason it's not working. I have confimred the following: <form> using method="post" and correct enctype correct file referenced from form directory has permissions 777 all the memory_limit , max_execution_time , etc are set to super high settings to avoid timeouts Basically, the script below returns with just Your image is too big. . I have also enabled ALL errors to display and still don't get an error. Any ideas? $time = time(); $target_path = "/absolute

The final output should be like image(HELLO WORLD): Here is what i am doing:- $im = imagecreate(400,400); $txtcol = imagecolorallocate($im, 0xFF, 0x00, 0x00); $size = 20; $txt = 'DUMMY TEXT'; $font = './font/Capriola-Regular.ttf'; /*two points for base line*/ $x1 = 50; $x2 = 300; $y1 = 150; $y2 = 170; /*bof finding line angle*/ $delta_x = $x2-$x1; $delta_y = $y2-$y1; $texangle = (rad2deg(atan2($delta_y,$delta_x)) * 180 / M_PI)-360; /*eof finding the line angle*/ imageline($im,$x1,$y1,$x2,$y2,$txtcol); //Drawing line imagettftext($im, $size, $texangle, $x1, $y1, $txtcol, $font, $txt); //

A simple question motivated by a curiosity, with probably a complex answer: Is it possible to emulate the new PHP 5.5 imagecrop() in earlier versions, like 5.4, by combining other GD functions? Awn.. But without the imagecrop() black line bug , please. :p This should be a drop-in replacement for imagecrop() (without the bug...): function mycrop($src, array $rect) { $dest = imagecreatetruecolor($rect['width'], $rect['height']); imagecopy( $dest, $src, 0, 0, $rect['x'], $rect['y'], $rect['width'], $rect['height'] ); return $dest; } Usage: $img = mycrop($img, ['x' => 10, 'y' => 10, 'width' => 100

Could you please explain what exactly the return value of imagettfbbox() mean? The manual says : imagettfbbox() returns an array with 8 elements representing four points making the bounding box of the text on success and FALSE on error. [...Table of points here...] The points are relative to the text regardless of the angle, so "upper left" means in the top left-hand corner seeing the text horizontally. But, I found it not very clear. For example, the return value: array(-1, 1, 61, 1, 61, -96, -1, -96) means the following points: (-1, -96) ------ (61, -96) | | | | | | | | | | | | (-1, 1) -----
