note 60183 added to function.imagettfbbox

Another function for centered text string. What it does: Generate a truecolor .png image of a text string. The image will be just large enough encompass the text and a 2 px border and the text will be centered in it. It is called from any other page like so... <img src="linkImg.php?text=php.net is great&border=out" /> // Text with #&+"'\<> will need to be escaped, but I've found spaces don't cause errors. I haven't tested this with any other languages. The following code is the file named linkImg.php The file was not designed to have anything else here with it, and the open and close php tags should the the very first and very last characters of the page respectively, as outside whitespace can be a little evil sometimes. <?php //Obtain text and border via GET //Border can be out, in, or flat $text = $_GET['text']; $border = $_GET['border']; $font = "fontpath"; //(str) "fonts/sasquatchlives.ttf" $fontsize = font size; //(int) pixels in GD 1, or points in GD 2 //Register box $box = imagettfbbox ($fontsize, 0, $font, $text); //Find out the width and height of the text box $textW = $box[2] - $box[0]; $textH= $box[3]-$box[5]; //Add padding $paddingx = 10; $paddingy = 10; //Set image dimentions $width = $textW+$paddingx; $height= $textH+$paddingy; //Bottom left corner of text $textx = $paddingx/2; $texty = $height - $paddingy/2; //Shadow offset (pixels) $shadoffx = 1; $shadoffy = 1; //Create the image $img = imagecreatetruecolor($width,$height); //Define some colors $white = imagecolorallocate($img,255,255,255); $black = imagecolorallocate($img,0,0,0); $lightgrey = imagecolorallocate($img,200,200,200); $grey = imagecolorallocate($img,100,100,100); //Define Text (fg) and background (bg) colors $bgcol = imagecolorallocate($img,192,213,196); //Celadon (light pastel green) $fgcol = imagecolorallocate($img,243,104,88); //Peach // Fill image with background color imagefill($img,0,0,$bgcol); //Write Shadow imagettftext($img, $fontsize, 0, $textx+$shadoffx, $texty+$shadoffy, $grey, $font, $text); //Write Text imagettftext($img, $fontsize, 0, $textx, $texty, $fgcol, $font, $text); //Bordering //Embossed border (button-looking) if ($border == "out") { imageline ($img,0,0,$width,0,$white);imageline ($img,0,0,0,$height,$white); imageline ($img,1,1,$width,1,$lightgrey);imageline ($img,1,1,1,$height-1,$lightgrey); imageline ($img,0,$height-1,$width-1,$height-1,$black);imageline ($img,$width-1,$height-1,$width-1,0,$black); imageline ($img,2,$height-2,$width-2,$height-2,$grey);imageline ($img,$width-2,$height-2,$width-2,2,$grey); } //Flat border if ($border == "flat") { imageline ($img,0,0,$width,0,$white);imageline ($img,0,0,0,$height,$white); imageline ($img,1,1,$width,1,$grey);imageline ($img,1,1,1,$height-1,$grey); imageline ($img,0,$height-1,$width-1,$height-1,$white);imageline ($img,$width-1,$height-1,$width-1,0,$white); imageline ($img,2,$height-2,$width-2,$height-2,$grey);imageline ($img,$width-2,$height-2,$width-2,2,$grey); } //Engraved border (pushed button) if ($border == "in") { imageline ($img,0,0,$width,0,$black);imageline ($img,0,0,0,$height,$black); imageline ($img,1,1,$width,1,$grey);imageline ($img,1,1,1,$height-1,$grey); imageline ($img,0,$height-1,$width-1,$height-1,$white);imageline ($img,$width-1,$height-1,$width-1,0,$white); imageline ($img,2,$height-2,$width-2,$height-2,$lightgrey);imageline ($img,$width-2,$height-2,$width-2,2,$lightgrey); } // Header info header("Content-type: image/png"); //Sends the image imagepng($img); imagedestroy($img); ?> Hope this helps someone! -Patrick- ---- Manual Page -- http://www.php.net/manual/en/function.imagettfbbox.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60183 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60183&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60183&report=yes Search -- http://master.php.net/manage/user-notes.php
