Hello again, i need to do a form that uploads an image, makes a thumbnail of it and puts a watermark image and text  on the thumbnail..

Iv managed to do the uploading part, making the thumbnail, then making a watermarked thumbnail (with image) , and i need some help with the watermark text part..

 

What im thinking of - generate a text image, then apply it to the watermark, then add the watermark with text to the thumbnail.

 

This is the function i used for the watermark image:

<?php
function watermark($original_image,$original_watermark,$destination="")
	{
		$image=imagecreatefromjpeg($original_image);
		list($imagewidth,$imageheight)=getimagesize($original_image);

		$watermark 	= 	imagecreatefrompng($original_watermark); 			
		list($watermarkwidth,$watermarkheight)=getimagesize($original_watermark);

		if($watermarkwidth>$imagewidth || $watermarkheight>$imageheight)
		{
			$water_resize_factor = $imagewidth / $watermarkwidth;
			$new_watermarkwidth  = $watermarkwidth * $water_resize_factor;
			$new_watermarkheight = $watermarkheight * $water_resize_factor;

			$new_watermark = imagecreatetruecolor($new_watermarkwidth , $new_watermarkheight);

			imagealphablending($new_watermark , false);
			imagecopyresampled($new_watermark , $watermark, 0, 0, 0, 0, $new_watermarkwidth, $new_watermarkheight, $watermarkwidth, $watermarkheight);

			$watermarkwidth  = $new_watermarkwidth; 
			$watermarkheight = $new_watermarkheight; 
			$watermark       = $new_watermark;
		}
		$startwidth 	= 	($imagewidth 	- 	$watermarkwidth)  / 2; 
		$startheight 	= 	($imageheight 	- 	$watermarkheight) / 2;

		imagecopy($image, $watermark, $startwidth, $startheight, 0, 0, $watermarkwidth, $watermarkheight); 
		if(!empty($destination))
			imagejpeg($image,$destination);
		else 
			imagejpeg($image);
	}	
?>

 

Can i insert in this function something like this? (the "Text" would appear on top of the watermark image in the middle) :

<?php
// Create the canvas
$canvas = imagecreate( 150, 80 );
// First colour - this will be the default colour for the canvas 
// $light_blue = imagecolorallocate( $canvas, 176, 226, 255 );
// The second colour - to be used for the text
$black = imagecolorallocate( $canvas, 0, 0, 0 );
// Path to the font you are going to use
$font = "verdana.ttf";
// Text to write
$text = "Text";
// Font size
$size = "40";
// Add the text to the canvas
imageTTFText( $canvas, $size, 0, 15, 60, $black, $font, $text );
// Save as Text.jpg
imagejpeg( $canvas, "Text.jpg" );
// Clear the memory of the tempory image 
ImageDestroy( $canvas );
?>

 

Thx in advance.

i tried but it just shows some weird symbols on my browser, ignores the text part completely, and just uploads with image watermark only

 

this is where i tried to write the code, idk if this is where i need to write smth, or i need to create a new function or smth..

           $imw = imagesx($im); // uploaded image width
                    $imh = imagesy($im); // uploaded image height
                    $nh = $thumbnailheight; // thumbnail height
                    $nw = round(($nh / $imh) * $imw); //thumnail width
                    $newim = imagecreatetruecolor ($nw, $nh);

				////////////THE TEXT WATERMARK PART/////////////////////
				$textim = imagecreatetruecolor ($nw, $nh); //creates image
				//$white = imagecolorallocate($textim, 255, 255, 255);
				//$grey = imagecolorallocate($textim, 128, 128, 128);
				$black = imagecolorallocate($textim, 0, 0, 0); //creates black color
				$start_x = $nh / 2; //possition where the text will be placed (in this case middle of thumbnail)
				$start_y = $nw / 2; 
				//imagefilledrectangle($textim, 0, 0, 399, 29, $white);
				//$text = 'Testing';
				//$font = 'Dunkin.ttf';
				//imagettftext($textim, 20, 0, 11, 21, $grey, $font, $text);
				imagettftext($textim, 5, 0, $start_x, $start_y, $black, 'Dunkin.ttf', "text"); //adds the text, with size 5, possition middle of thumbnail, black color, font 'dunkin', and text "text"
				//imagettftext($textim, 20, 0, 10, 20, $black, $font, $text);
				imagepng($textim);  //?????
				imagedestroy($textim);  //?????
				///////////////////////////////////////////			


                    imagecopyresampled ($newim,$im, 0, 0, 0, 0, $nw, $nh, $imw, $imh) ;
                    $thumbfilename = $thumbnailfolder.$uploadfilename ;
