General Discussion

Thank you, you helped me a lot, it worked!

Some time ago I adjusted the emblem display on the website, but I don't remember which file I modified. I think it was related to the imagecreatefrombmpstring function, but I could be wrong - it wasn't too difficult to fix it. Below I'm sending potential files that may have been changed, compare them with your own files. Also, pay attention to the PHP error logs - often the solution lies there.   \lib\Flux\EmblemExporter.php <?php require_once 'functions/imagecreatefrombmpstring.php'; /** * */ class Flux_EmblemExporter { /** * */ public $loginAthenaGroup; /** * */ public $athenaServers = array(); /** * */ public function __construct(Flux_LoginAthenaGroup $loginAthenaGroup) { $this->loginAthenaGroup = $loginAthenaGroup; } /** * */ public function addAthenaServer(Flux_Athena $athenaServer) { if (!in_array($athenaServer, $this->loginAthenaGroup->athenaServers, true)) { throw new Flux_Error( "{$athenaServer->serverName} is not a valid char/map server defined in the {$this->loginAthenaGroup->serverName} group."); } $this->athenaServers[$athenaServer->serverName] = $athenaServer; } /** * */ public function exportArchive() { $topDir = $this->sanitizePathName($this->loginAthenaGroup->serverName); $tmpDir = FLUX_DATA_DIR.'/tmp'; $tmpFile = tempnam($tmpDir, 'zip'); // Create zip archive. $zip = new ZipArchive(); $zip->open($tmpFile, ZIPARCHIVE::OVERWRITE); $zip->addEmptyDir($topDir); foreach ($this->athenaServers as $athenaServer) { $athenaDir = $this->sanitizePathName($athenaServer->serverName); $zip->addEmptyDir("$topDir/$athenaDir"); $sql = "SELECT name, emblem_data FROM {$athenaServer->charMapDatabase}.guild WHERE emblem_len > 0 ORDER BY name ASC"; $sth = $athenaServer->connection->getStatement($sql); $sth->execute(); $guilds = $sth->fetchAll(); if ($guilds) { foreach ($guilds as $guild) { $emblemData = @gzuncompress(pack('H*', $guild->emblem_data)); $emblemImage = imagecreatefrombmpstring($emblemData); ob_start(); imagepng($emblemImage); $data = ob_get_clean(); $emblemName = sprintf('%s.png', $this->sanitizePathName($guild->name)); $zip->addFromString("$topDir/$athenaDir/$emblemName", $data); } } } // Close archive. $zip->close(); // Send out appropriate HTTP headers. $filename = urlencode(sprintf('%s-%s-emblems.zip', strtolower($topDir), date('Ymd'))); header('Content-Type: application/zip'); header('Content-Length: '.filesize($tmpFile)); header("Content-Disposition: attachment; filename=$filename"); // Read contents of the file. readfile($tmpFile); // Remove temporary file. unlink($tmpFile); exit; } /** * */ private function sanitizePathName($pathName) { return preg_replace('/[^\w\d ]+/', '', $pathName); } } ?>   \lib\functions\imagecreatefrombmpstring.php <?php /** * Convert a bmp string to Image resource * @param {string} $data - BMP string content * @return {resource} image resource */ function imagecreatefrombmpstring($data) { // Read header extract( unpack("a2signature/x8/Voffset/x4/Vwidth/Vheight/x2/vbits", substr($data, 0, 30))); if ($signature !== 'BM') { return false; } // Create image $img = imagecreatetruecolor($width, $height); imagealphablending($img, false); imagesavealpha($img, true); // Load palette (if used) $paletteSize = $offset - 54; $imagePalette = array(); if ($paletteSize > 0 && $bits < 16) { $palette = unpack('C'. $paletteSize, substr($data, 54, $paletteSize)); for ($i = 1, $p = 0; $i < $paletteSize; $i += 4, $p++ ) { $b = $palette[$i+0]; $g = $palette[$i+1]; $r = $palette[$i+2]; $a = $palette[$i+3]; // Magenta is transparent. if (($r & 0xf8 === 0xf8) && ($g === 0) && ($b & 0xf8 === 0xf8)) { $a = 127; } $imagePalette[$p] = imagecolorallocatealpha($img, $r, $g, $b, $a); } } // Read ImageData $skip = ( 4 - ( (( ($bits * $width) + 7) >> 3 ) & 3 ) ) % 4; $size = $width * $height * ($bits >> 3) + $skip * $height; $imageData = unpack('C'. $size, substr($data, $offset, $size) ); switch ($bits) { // Not an original DIB file ?

Please help me fix the display of the logos.

Any link for this?
