php - Merge two images with GD Library, have 1 repeat in background -


i want take image has transparency , overlay on top of 60x60 (arbitrary size) image repeats width , length of first image...

so use image 2 repeating background image image 1 on top of.

edit:

okay, used 1 trick pony's solution, tried modify create square image out of rectangle if width less height, not stretch original image , instead center it. able center image repeating background not continue repeating after overlay image stops.

here code:

    <?php      $overlay    = imagecreatefrompng('../images/' . $_request['overlay']);      $repeating  = '../images/' . $_request['repeating'];     $ext = explode('.', $_request['repeating']);     $ext = strtolower($ext[1]);       if ($ext == 'gif')         $repeating  = imagecreatefromgif($repeating);     elseif ($ext == 'png')         $repeating  = imagecreatefrompng($repeating);     elseif ($ext == 'jpg' || $ext == 'jpeg')         $repeating  = imagecreatefromjpeg($repeating);       $w          = imagesx($overlay);     $h          = imagesy($overlay);     if ($w < $h)          $w = $h;      $output = imagecreatetruecolor($w, $h);     imagealphablending($output, true);       imagesettile($output, $repeating);     imagefill($output, 0, 0, img_color_tiled);     imagedestroy($repeating);          $offsetx = ($w - imagesx($overlay)) / 2;      imagecopy($output, $overlay, $offsetx, 0, 0, 0, $w, $h);     imagedestroy($overlay);       header('content-type: image/png');     imagepng($output);     imagedestroy($output);        ?>

edit 2:

overlay: http://72.167.52.68/~viisi/ebaylist/images/back_test2.png

repeating: http://72.167.52.68/~viisi/ebaylist/images/back_test.gif

expected result (but continue repeating across whole image): http://72.167.52.68/~viisi/ebaylist/image/previewimage.php?overlay=back_test2.png&repeating=back_test.gif

$overlay = imagecreatefrompng('/path/to/transparent/image.png'); $repeating = imagecreatefrompng('/path/to/repeating/image.png');  // create new image matching overlay size $w = imagesx($overlay); $h = imagesy($overlay); $output = imagecreatetruecolor($w, $h); imagealphablending($output, true); imagesavealpha($output, true);  // tile repeating image on imagesettile($output, $repeating); imagefill($output, 0, 0, img_color_tiled); imagedestroy($repeating);      // add overlay on top imagecopy($output, $overlay, 0, 0, 0, 0, $w, $h); imagedestroy($overlay);  // send screen header('content-type: image/png'); imagepng($output); imagedestroy($output);

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
