but when i upload png , gif it stored in my folder but the image is blank with black background color.
is there any way to solve this?
$water_mark_text_2 = "text";

function watermark_text($oldimage_name, $new_image_name){
global $font_path, $font_size, $water_mark_text_1, $water_mark_text_2;
list($width,$height) = getimagesize($oldimage_name);
$image = imagecreate(100, 100);
// sets some colors
$white = imagecolorallocate($image, 255, 255, 255);
$black = imagecolorallocate($image, 0, 0, 0);
$image = imagecreatetruecolor($width, $height);
$image_src = imagecreatefromjpeg($oldimage_name);
imagecopyresampled($image, $image_src, 0, 0, 0, 0, $width, $height, $width, $height);

// imagettftext($image, $font_size, 0, 30, 190, $black, $font_path, $water_mark_text_1);
imagettftext($image, $font_size, 0, 5, 20, $white, $font_path, $water_mark_text_2);
imagejpeg($image, $new_image_name, 100);
imagedestroy($image);
unlink($oldimage_name);
return true;
}
$path = "$stored/";
$valid_formats = array("jpg", "bmp","jpeg","JPG","png");
$name = $_FILES['img']['name'];
list($txt, $ext) = explode(".", $name);
$upload_status = move_uploaded_file($_FILES['img']['tmp_name'],$path.$name);
$new_name = $stored.$md5_img.".jpg";
watermark_text($path.$_FILES['img']['name'], $new_name);
if i change imagecreatefromjpeg to imagecreatefrompng , and imagejpg to imagepng.
the image still upload , but i cannot opened.

I want to save my pngs, but my code does not allow me to create new pngs or overwrite the existing ones. Ideally every time the page is loaded the image would be saved.
<?php
$width = 640;
$height = 480;
$font = 23;
$string = "This is my text";
$im = #imagecreatetruecolor($width, $height);
imagesavealpha($im, true);
imagealphablending($im, false);
$white = imagecolorallocatealpha($im, 255, 255, 255, 127);
imagefill($im, 0, 0, $white);
$lime = imagecolorallocate($im, 0, 0, 51);
imagettftext($im, $font, 0, 0, $font - 3, $lime, "./DroidSerif-Bold.ttf", $string);
$im = imagecreatefrompng("test.png");
imagedestroy($im);
?>
imagecreateFROMpng as it names indicates creates an image object by reading a .PNG file. In order to save the image as a PNG, you must use the imagepng function:
...
imagettftext($im, $font, 0, 0, $font - 3, $lime, "./DroidSerif-Bold.ttf", $string);
imagepng($im, "test.png");
imagedestroy($im);
I have this script, which makes an image and posts it on another image:
<?php
$img=imagecreatetruecolor(150,20);
imagealphablending($img,false);
$col=imagecolorallocatealpha($img,255,255,255,127);
$black = imagecolorallocate($img, 0, 0, 0);
imagecolortransparent($img, $black);
imagefilledrectangle($img,0,0,180,20,$col);
imagealphablending($img,true);
$font='../ttf/0001.ttf';
$color = imagecolorallocate($img, 0, 0, 0);
imagettftext($img,11,0,5,14,$color,$font,'Text goes here');
imagealphablending($img,false);
imagesavealpha($img,true);
imagejpeg($img, '../custom_images/test.jpg');
// Create image instances
$dest = imagecreatefromjpeg('../custom_images/121536.jpg');
$src = imagecreatefromjpeg('../custom_images/test.jpg');
$width = imagesx($src);
$height = imagesy($src);
imageantialias($src, true);
$color = imagecolorallocatealpha($src, 0, 0, 0, 127);
$rotated = imagerotate($src, 0, $color);
imagesavealpha($rotated, true);
$trans_colour = imagecolorallocatealpha($rotated, 0, 0, 0, 127);
imagefill($rotated, 0, 0, $trans_colour);
imagepng($rotated, 'shahid.png');
$new_img = imagecreatefrompng('shahid.png');
$width = imagesx($new_img);
$height = imagesy($new_img);
// imagecopymerge($dest, $new_img, 50, 50, 0, 0, $width+60, $height+60, 100);
imagecopymerge_alpha($dest, $new_img, 0, 20, 0, 0, $width, $height, 100);
// Output and free from memory
header('Content-Type: image/png');
imagepng($dest);
imagedestroy($dest);
imagedestroy($src);
?>
2 things:
Background is not transparent
I want the Width and Height to be automatic, so if the text is short, the image is it to.
What do I fault?
This question already has an answer here:
PHP & GD - transparent background being filled with nearby color
(1 answer)
Closed 8 years ago.
I am writing the code for watermark in php using below code but for transaparent images, black background is coming:
$font_path = $_SERVER['DOCUMENT_ROOT'] . "/fonts/arial.ttf"; // Font file
$water_mark_text_2 = "IndustrialStores.com"; // Watermark Text
list($owidth,$oheight) = getimagesize($oldimage_name);
$width = $owidth;
$height = $oheight;
$image = imagecreatetruecolor($width, $height);
$extension = pathinfo($oldimage_name, PATHINFO_EXTENSION);
$extension = strtolower($extension);
if($extension=="jpg" || $extension=="jpeg" ){
$image_src = imagecreatefromjpeg($oldimage_name);
}
else if($extension=="png"){
$image_src = imagecreatefrompng($oldimage_name);
}
else if($extension=="gif"){
$image_src = imagecreatefromgif($oldimage_name);
}
else if($extension=="bmp"){
$image_src = imagecreatefrombmp($oldimage_name);
}
else{
copy($oldimage_name, $new_image_name);
unlink($oldimage_name);
return true;
}
imagecopyresampled($image, $image_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
$blue = imagecolorallocate ($image, 179, 179, 179);
$bbox = imageftbbox($width/15, 0, $font_path, 'IndustrialStores.com');
$x = $bbox[0] + (imagesx($image) / 2) - ($bbox[4] / 2);
$y = $bbox[1] + (imagesy($image) / 2) - ($bbox[5] / 2) - 5;
imagettftext($image, $width/15, 0, $x, $y, $blue, $font_path, $water_mark_text_2);
imagejpeg($image, $new_image_name, 100);
imagedestroy($image);
unlink($oldimage_name);
I already tried so many other answers fro stackoverflow like using :
$im = imagecreatetruecolor(55, 30);
$red = imagecolorallocate($im, 255, 0, 0);
$black = imagecolorallocate($im, 0, 0, 0);
// Make the background transparent
imagecolortransparent($im, $black);
but there is no use of all this
Would adding these lines help?
else{
copy($oldimage_name, $new_image_name);
unlink($oldimage_name);
return true;
}
// add these lines here!
imagealphablending($image, false);
imagesavealpha($image, true);
imagecopyresampled($image, $image_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
$blue = imagecolorallocate ($image, 179, 179, 179);
I have an image and I'm trying to watermark the image using text.
I have done with code part, but no image see been viewed with watermark text.
Here is the code below:
$imagetobewatermark="images/muggu.png";
list($width,$height)=getimagesize($imagetobewatermark);
$imagetobewatermark=imagecreatetruecolor($width,$height);
$mark=imagecreatefrompng($imagetobewatermark);
imagecopy($imagetobewatermark,$mark,0,0,0,0,$width,$height);
$wartermarktext="Muggu";
$font="../font/century gothic.ttf";
$fontsize="15";
$white = imagecolorallocate($imagetobewatermark, 255, 255, 255);
imagettftext($imagetobewatermark, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
imagepng($imagetobewatermark);
imagedestroy($imagetobewatermark);
Tell me If I'm wrong.
Thank you.
One problem I can see straight away is that the $imagetobewatermark variable starts off as a string, then becomes a new blank image object (not an existing image), and when you subsequently create the mark image object, it's not going to work because $imagetobewatermark is no longer a string.
Try:
$imagetobewatermark=imagecreatefrompng("images/muggu.png");
$watermarktext="Muggu";
$font="../font/century gothic.ttf";
$fontsize="15";
$white = imagecolorallocate($imagetobewatermark, 255, 255, 255);
imagettftext($imagetobewatermark, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
imagepng($imagetobewatermark);
imagedestroy($imagetobewatermark);
EDIT:
I failed to notice a typo in your text variable $wartermarktext, which should be $watermarktext.
Correct this and it should work.
You had some spellings wrong and did not use the ressource. Here corrected:
$imagetobewatermark = "muggu.png";
list ($width, $height) = getimagesize($imagetobewatermark);
$res = imagecreatetruecolor($width, $height);
$mark = imagecreatefrompng($imagetobewatermark);
//make sure here to use the ressource, not the filepath
imagecopy($res, $mark, 0, 0, 0, 0, $width, $height);
$watermarktext = "Muggu";
//$font = "../font/century gothic.ttf";
//I copied it to my local test folder
$font = "GOTHIC.TTF";
$fontsize = "15";
//make sure here to use the ressource, not the filepath
$white = imagecolorallocate($res, 255, 255, 255);
//make sure here to use the ressource, not the filepath
imagettftext($res, $fontsize, 0, 20, 10, $white, $font, $watermarktext);
header("Content-type:image/png");
//make sure here to use the ressource, not the filepath
imagepng($res);
//make sure here to use the ressource, not the filepath
imagedestroy($res);
you have to give Public/Absolute Path for Font arial.ttf.
Solution is tested in Laravel 5.8.
you can use this solution. here [ $SourceFile , $DestinationFile ] are Absolute Path of local directory. $imgUrl is HTTP based URL. Watermark will be placed at the top of the image.
function watermarkImage ($SourceFile, $WaterMarkText, $DestinationFile,$imgUrl) {
list($width, $height) = getimagesize($SourceFile);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($SourceFile);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height);
$black = imagecolorallocate($image_p, 255, 255, 255);
$font = public_path('fonts/arial.ttf');
$font_size = 8;
imagettftext($image_p, $font_size, 0, 10, 20, $black,$font , $WaterMarkText);
if ($DestinationFile <> '') {
imagejpeg ($image_p, $DestinationFile, 100);
} else {
header('Content-Type: image/jpeg');
imagejpeg($image_p, null, 100);
};
imagedestroy($image);
imagedestroy($image_p);
return $imgUrl;
}
Try this.
$imagetobewatermark = "images/muggu.png";
$watermarktext = "Muggu";
list($width, $height) = getimagesize($imagetobewatermark);
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefrompng($imagetobewatermark);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width, $height);
$font = "../font/century gothic.ttf";
$font_size = 15;
$white = imagecolorallocate($image_p, 255, 255, 255);
imagettftext($image_p, $font_size, 0, 20, 20, $white, $font, $watermarktext);
header("Content-Type: image/png");
imagepng($image_p, null, 0);
imagedestroy($image);
imagedestroy($image_p);
Try this code, It helps you to provide the watermark for the images.
<?php
header('Content-type: image/jpeg'); //SET THE FORMATE OF THE IMAGE
$jpg_image = imagecreatefromjpeg('images.jpg'); //GIVE LINK FOR SPECIFIED IMAGE
$color = imagecolorallocate($jpg_image, 500, 500, 500); //GIVE COLOR TO WATERMARK TEXT
$font_location = 'BROADW.TTF'; //WATERMARK FONT
$text = "http://www.sanwebtutorials.blogspot.in/"; //WATERMARK TEXT
$x=200; //X CO-ORDINATE
$y=800; //Y CO-ORDINATE
$size=21; //SIZE OF TEXT
imagettftext($jpg_image,$size, 0, $x, $y, $color, $font_location, $text); //PRINT TEXT ON IMAGE
imagejpeg($jpg_image); //SEND IMAGE TO BROWSER
imagedestroy($jpg_image); //DESTROY THE MEMORY
?>
<?php
header('Content-type:image/gif');
header('Content-Disposition: attachment; filename="animated.gif"');
require_once('GIFEncoder.class.php');
$image = imagecreatefrompng('source01.png');
$width = 50;
$height = 50;
$new_image = imagecreatetruecolor($width, $height);
imagecopyresampled($new_image, $image, 0, 0, 0, 0, $width, $height, 200, 115);
$text_color = imagecolorallocate($image, 50, 50, 50);
imagestring($image, 5, 5, 5, '', $text_color);
/* $imageMagick = new Imagick($image);
$imageMagick->adaptiveResizeImage(50,50); */
ob_start();
imagegif($image);
$frames[]=ob_get_contents();
$framed[]=40;
ob_end_clean();
$gif = new GIFEncoder($frames,$framed,0,2,0,0,0,'bin');
echo $gif->GetAnimation();
//$fp = fopen('animegif.gif', 'w');
//fwrite($fp, $gif->GetAnimation());
//fclose($fp);
?>
Is there any way to resize the .png image by code to a static 50x50px value? Thanks
I would use imagecopyresampled
It can used like this:
$width = 50;
$height = 50;
$new_image = imagecreatetruecolor($width, $height);
imagecopyresampled($new_image, $image, 0, 0, 0, 0, $width, $height, $image.getWidth)=(), $image.getHeight());
You can use imagemagic for that
