Note Submitter: php at webdecker dot de ---- To get the horizontal and vertical resolution you could add some lines to the previous code of alexander. BMP stores the resolution in pixels per meter. To get it as pixels per inch (dpi) you have to multiply the value by 0.0254. <?php public function imagecreatefrombmp($p_sFile) { // ... // ... insert after the lines where you get width and height... // Get the horz. resolution in pixel per meter, 4 bytes $dpix = hexdec($header_parts[39]. $header_parts[38]) * 0.0254; // Get the vert. resolution in pixel per meter, 4 bytes $dpiy = hexdec($header_parts[43]. $header_parts[42]) * 0.0254; // ... rest of the code... return ($image, $dpix, $dpiy); } ?>
