note 82799 added to function.imagesetpixel

here's my version of imagecreatefromtga() that's been tested to work for targa 16 .. adapted from offering by zehao dot chang at gmail dot com function imagecreatefromtga($filename) { $data = file_get_contents($filename); // Extract header information $string_length = fileint($data, 1, 1); $data_type = fileint($data, 2, 1); $width = fileint($data, 12, 2); $height = fileint($data, 14, 2); $bits_per_pixel = fileint($data, 16, 1); $bytes_per_pixel = (int) $bits_per_pixel / 8; // Currently only supporting RGB Data type switch ($data_type) // Header information taken from http://astronomy.swin.edu.au/~pbourke/dataformats/tga/ { case 2: // Uncompressed RGB image break; case 0: // No attached image data case 1: // Uncompressed color-mapped image case 3: // Uncompressed black and white image case 9: // Runlength encoded color-mapped image case 10: // Runlength encoded RGB image case 11: // Compressed black and white image case 32: // Compressed color-mapped data, using Huffman, Delta, and runlength encoding case 33: // Compressed color-mapped data, using Huffman, Delta, and runlength encoding. 4-pass quadtree-type process default: return NULL; // No support for any of these types } // Compute things we need from the header information $pointer = 18 + $string_length; $x = 0; $y = $height - 1; $image = imagecreatetruecolor($width, $height); while ($pointer < strlen($data)) { if ($bytes_per_pixel == 2) // TARGA 16 - ARRRRRGG GGGBBBBB { $word = fileint($data, $pointer, 2); $r = ($word & 0x7C00) >> 10; $g = ($word & 0x03E0) >> 5; $b = ($word & 0x001F); imagesetpixel($image, $x, $y, $r << 19 | $g << 11 | $b << 3); } else if ($bytes_per_pixel == 3) // TARGA 24 - RRRRRRRR GGGGGGGG BBBBBBBB { imagesetpixel($image, $x, $y, fileint($data, $pointer, 3)); } else if ($bytes_per_pixel == 4) // TARGA 32 - AAAAAAAA RRRRRRRR GGGGGGGG BBBBBBBB { imagesetpixel($image, $x, $y, fileint($data, $pointer + 1, 3)); } if (++$x == $width) { $y--; $x = 0; } $pointer += $bytes_per_pixel; } return $image; } function fileint($data, $pos, $len) { return base_convert(bin2hex(strrev(substr($data, $pos, $len))), 16, 10); } ---- Server IP: 209.41.74.194 Probable Submitter: 72.70.34.145 ---- Manual Page -- http://www.php.net/manual/en/function.imagesetpixel.php Edit -- https://master.php.net/note/edit/82799 Del: integrated -- https://master.php.net/note/delete/82799/integrated Del: useless -- https://master.php.net/note/delete/82799/useless Del: bad code -- https://master.php.net/note/delete/82799/bad+code Del: spam -- https://master.php.net/note/delete/82799/spam Del: non-english -- https://master.php.net/note/delete/82799/non-english Del: in docs -- https://master.php.net/note/delete/82799/in+docs Del: other reasons-- https://master.php.net/note/delete/82799 Reject -- https://master.php.net/note/reject/82799 Search -- https://master.php.net/manage/user-notes.php
