PHP - Php Gd Image Transparency

Hey guys i am currently working on a thumbnail script. The idea is to be able to resize any image on the fly by adding some parameters to the images url ex: thisimage.jpg~160x160 It's then picked up by an htaccess rule that sends it to a php script that resize the image and returns it using the GD library. The script is working great but got a problem keeping the transparency with PNG images ... What ever i do the resized image has a black background. I tryed all sorts of things but it's just not working ... can anybody help me understand where i got it wrong?

// [......]

        // Create output image
        $outImg = imagecreate ($outWidth, $outHeight);
        
        // Load src image
        switch($srcType) {
            case "png":
                $srcImg = imagecreatefrompng($uri);
                $background = imagecolorallocate($srcImg, 255, 255, 255);
                imagecolortransparent($srcImg, $background);
                imagealphablending($srcImg, true);
                imagesavealpha($srcImg, true);
                break;
            case "gif":
                $srcImg = imagecreatefromgif($uri);
                break;
            case "jpeg":
                $srcImg = imagecreatefromjpeg($uri);
                break;
            default: 
                diewith("unsupported file type '$uri'");
        };

        // Resize image
        imagecopyresampled($outImg, $srcImg, 0, 0, 0, 0, $outWidth, $outHeight, $srcWidth, $srcHeight);

I am having difficulty keeping transparency on my png resizing function.  I have searched all around and tried various solutions.  However, all I keep getting is a black background.  Everything else about the function is working fine.  Any help would be appreciated.

Here is the code for transparency that isn't working:
Code: [Select]
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagealphablending($dst_img,false);
imagesavealpha($dst_img,true);
$transparent = imagecolorallocatealpha($dst_img, 255, 255, 255, 127);
imagefilledrectangle($dst_img, 0, 0, $thumb_w, $thumb_h, $transparent);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);
Here is the full function code:
Code: [Select]
function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(".",$name);
if (preg_match("/jpg|jpeg/",$system[1]))
{
$src_img=imagecreatefromjpeg($name);
}
if (preg_match("/png/",$system[1]))
{
$src_img=imagecreatefrompng($name);
}
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
if ($old_x < $old_y)
{
$thumb_w=$old_x*($new_w/$old_y);
$thumb_h=$new_h;
}
if ($old_x == $old_y)
{
$thumb_w=$new_w;
$thumb_h=$new_h;
}
$dst_img=ImageCreateTrueColor($thumb_w,$thumb_h);
imagealphablending($dst_img,false);
imagesavealpha($dst_img,true);
$transparent = imagecolorallocatealpha($dst_img, 255, 255, 255, 127);
imagefilledrectangle($dst_img, 0, 0, $thumb_w, $thumb_h, $transparent);
imagecopyresampled($dst_img,$src_img,0,0,0,0,$thumb_w,$thumb_h,$old_x,$old_y);

if (preg_match("/png/",$system[1]))
{
imagepng($dst_img,$filename);
} else {
imagejpeg($dst_img,$filename);
}
imagedestroy($dst_img);
imagedestroy($src_img);
}

I have a transparency color set up with my GD script.  It makes the image semi transparent with an ugly border.  Any tips or Hints?
Page:  http://www.zeldadungeon.net/Justin/miniheros/test.php
Code: [Select]
<?
$bg = imagecreatefrompng('http://i241.photobucket.com/albums/ff279/tiger_leo/reddraft.png');

$color = imagecolorallocate($bg, 168, 97, 97);

$font = './BOOKOS.TTF';

$insert = imagecreatefrompng('http://i241.photobucket.com/albums/ff279/tiger_leo/heartdraft.png');
imagealphablending($insert, true);
imagesavealpha($insert, true);

 
$xOffset = 20;   $yOffset = 20;

imagecolortransparent($insert, $color);

$insert_x = imagesx($insert); $insert_y = imagesy($insert); 

header('Content-Type: image/png');

imagecopymerge($bg,$insert,$xOffset,$yOffset,0,0,$insert_x,$insert_y,100);

imagepng($bg);
imagedestroy($bg); 

?>

I would like to select a color that isn't in an image, any thoughts on the best way? Maybe this isn't even the best way to do this.

I am using imagerotate, and for the 3rd parameter, I would like the uncovered area to  be transparent. I have done this, but I had to use a color then make every color in the image of that color transparent. so, either what is the best way:

A. Is there a good way to do this?
B. save every pixel color in an array then loop though the array testing colors that are not in the array and setting that as the transparent value.
C. Other. What?

Im trying to make a script that previews the level for a game, but im having issues with transparency and the rotation of each image.

you can see the problem he http://beta.trackmill.com/DUI/preview/

here is the php file

<?php
header('Content-Type: image/png');
$image = imagecreatefrompng('images/Background.png');

function radiansToDegrees($radians)
{
    return $radians * 180 / pi();
}
$map = file_get_contents('map.txt');
$blocks = split("<obj", $map);
for($i=2; $i<count($blocks); $i++)
{
$arg = split(" ", $blocks[$i]);
$n = str_replace("n", "", str_replace("=", "", str_replace('"', "", $arg[1])));
$x = str_replace("x", "", str_replace("=", "", str_replace('"', "", $arg[2])));
$x = $x * 20 - 13;
$y = str_replace("y", "", str_replace("=", "", str_replace('"', "", $arg[3])));
$y = $y * 22 + 15;
$a = str_replace("a", "", str_replace("=", "", str_replace('"', "", $arg[4])));
$a = radiansToDegrees($a);
$t = str_replace("t", "", str_replace("=", "", str_replace('"', "", $arg[5])));
$e = str_replace("e", "", str_replace("=", "", str_replace('"', "", $arg[6])));
$f = str_replace("f", "", str_replace("=", "", str_replace('"', "", str_replace('/>', "", $arg[7]))));
$blockimage = imagecreatefrompng("images/$n.png");

$blockimage = imagerotate($blockimage, -$a, 0, 0) ;
imagealphablending($blockimage, false);
imagesavealpha($blockimage, true);

imagecopy($image, $blockimage, $x, $y, 0, 0, imagesx($blockimage), imagesy($blockimage));
//echo "$i | $n - $x - $y - $a - $t - $e - $f <br>";
}

imagepng($image);
imagedestroy($image);
?>


if you require the .zip containing the images etc, just reply and i will upload it as soon as possible

I have tried many solution, but nothing seems to fix this.
The problem is that i put an image with transparency on top of another image, but the transparent pixels still transparent, where they should show some of the image below it.

If you call it with l=100 and p=20 i would get this result http://cl.ly/566Z instead of this http://cl.ly/56OF.

Here is the source code and I have attached the images:
Code: [Select]
<?php
header('Content-type: image/png');
echo imagepng(progressbar($_GET['l'], $_GET['p']));
function progressbar($length, $percentage)
{
$length = round($length / 2) * 2;
$percentage = min(100, max(0, $percentage));
if($length > 0)
{
$bar = imagecreate($length, 14);
imagealphablending($bar, false);
imagesavealpha($bar, true);
$empty = imagecreatefrompng('Empty.png');
imagealphablending($empty, false);
imagesavealpha($empty, true);
$fill = imagecreatefrompng('Fill.png');
imagealphablending($fill, false);
imagesavealpha($fill, true);
$lempty = imagecreatefrompng('LeftEmpty.png');
imagealphablending($lempty, false);
imagesavealpha($lempty, true);
$lfill = imagecreatefrompng('LeftFill.png');
imagealphablending($lfill, false);
imagesavealpha($lfill, true);
$rempty = imagecreatefrompng('RightEmpty.png');
imagealphablending($rempty, false);
imagesavealpha($rempty, true);
$rfill = imagecreatefrompng('RightFill.png');
imagealphablending($rfill, false);
imagesavealpha($rfill, true);
$emptycaplength = min(7, $length / 2); //5 
imagecopy($bar, $lempty, 0, 0, 0, 0, $emptycaplength, 14);
imagecopy($bar, $rempty, $length - $emptycaplength, 0, 7 - $emptycaplength, 0, $emptycaplength, 14);
if($length > 14)
{
imagecopyresized($bar, $empty, 7, 0, 0, 0, $length - 14, 14, 1, 14);
}
$filllength = round(($length * ($percentage / 100)) / 2) * 2;
$fillcaplength = min(7, $filllength / 2);
imagecopy($bar, $lfill, 0, 0, 0, 0, $fillcaplength, 14);
imagecopy($bar, $rfill, $filllength - $fillcaplength, 0, 7 - $fillcaplength, 0, $fillcaplength, 14);

return $bar;
}
else

Hi, I've read a lot of places that it's not recommended to store binary files in my db.
So instead I'm supposed to upload the image to a directory, and store the link to that directory in database.

First, how would I make a form that uploads the picture to the directory (And what kinda directories are we talking?).

Secondly, how would I retrieve that link? And I guess I should rename the picture..

I'd appreciate any help, or a good tutorial (Haven't found any myself).

The script for creating a new file name for the image:

        $validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
        $ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.) 
        $file_extension = end($ext); //store extensions in the variable

        $new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
		$target_path = $target_path . $new_image_name;//set the target path with a new name of image

The script creates a new file like:

f6c9b8d9db05366c3504210cded9ddb2.jpg

and moves the file to the "uploads" folder. And then the script also creates a thumbnail with the same file name and moves the file to the "thumbs" folder.   The issue I am having is that the same ID code could happen again for a different image in the database, thus I would be calling a different original sized image than the thumbnail image.   My question is: How to avoid this issue of the same ID code has happened again for a different file. What is the proper way to reference the anchor tag of the thumbnail image to its actual original sized image?   With the script I have the thumbnail image would be coming from the "thumbs" folder and the anchor tag would get referenced to the "uploads" folder to get the original sized image.

How can i edit just one image at on time with a multiple image upload form? I have the images being stored in a folder and the path being stored in MySQL. I also have the files being uploaded with a unique id. My issue is that I want to be able to pass the values of what is already in $name2 $name3 $name4 if I only want to edit $name1. I don't want to have to manually update the 4 images. Here is the PHP:
Code: [Select]
<?php

    $tmpName = $file['tmp_name'];
    $fileSize = $file['size'];
    $fileType = $file['type'];

    if ($fileName != ""){
        $filePath = $uploadDir;
        $fileName = str_replace(" ", "_", $fileName);

        //Split the name into the base name and extension
        $pathInfo = pathinfo($fileName);
        $fileName_base = $pathInfo['fileName'];
        $fileName_ext = $pathInfo['extension'];

        //now we re-assemble the file name, sticking the output of uniqid into it
        //and keep doing this in a loop until we generate a name that 
        //does not already exist (most likely we will get that first try)
        do {
           $fileName = $fileName_base . uniqid() . '.' . $fileName_ext;
        } while (file_exists($filePath.$fileName));

$file_names [] = $fileName;

        $result = move_uploaded_file($tmpName, $filePath.$fileName);
    }


if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
$fileinsert[] = $filePath;

}

$update = "INSERT INTO image

           VALUES
               ('$mid', '$cat', '$item', '$price', '$about', '$values[0]', '$values[1]', '$values[2]', '$values[3]')
           ON DUPLICATE KEY UPDATE

Would like to be able to click on a radio button that represents an image. Once selected and submitted, have that image display on another page. I have an idea, but need some guidance.

BTW, is using php only doable? Is there a simpler or more elegant way to do this?

Thanks all!

Can I get some help or a point in the right direction. I am trying to create a form that allows me to add, edit and delete records from a database. I can add, edit and delete if I dont include the image upload code. If I include the upload code I cant edit records without having to upload the the same image to make the record save to the database. So I can tell I have got the code processing in the wrong way, thing is I cant seem to see or grasp the flow of this, to make the corrections I need it work. Any help would be great!   Here is the form add.php code

Hello,
I've had success creating a cool vanity QR code with rounded edges for my organization by generating a standard QR code, then applying a noise -> median effect in Photoshop to get the edges rounded among some other effects.



Photoshop is great, but I want to automate this. I found a great PHP library to generate QR codes. The part I don't get is the rounding of the hard edges.

I've seen other sites do it like this one.

So far google searches are yielding rounded corner tutorials. Any thoughts on how to do this with GD or ImageMagic?

Best regards,

Chris

Hello

I am having problems uploading an image through a HTML form. I want the image to be uploaded to the server and the image name to be written to the mysql database.

Below is the code I am using:
Code: [Select]
<?php
if (isset($_POST['add'])){
   
   echo "<br /> add value is true";
      $name = $_POST['name'];   
      $description = $_POST['description'];   
      $price = $_POST['price'];
      $category_id = $_POST['category_name'];
      $image = $_FILES['image']['name'];   
      
      //file path of the image upload
      $filepath = "../images/";
      //mew name for the image upload
      $newimagename = $name;
      //new width for the image
      $newwidth = 100;
      //new height for the image
      $newheight = 100;
      
      include('../includes/image-upload.php');
      
      
      mysql_query("INSERT INTO item (item_name, item_description, item_price, item_image)
      VALUES ('$name','$description','$price','$image')"); ?>

Here is the image-upload.php file code:

Code: [Select]
<?php

//assigns the file to the image
$image =$_FILES["image"]["name"];
$uploadedfile =$_FILES["image"]["tmp_name"];

if ($image) {
   //retrieves the extension type from image upload
   $extension = getextension($image);
   //converts extension to lowercase
   $extension = strtolower($extension);
   
   //create image from uploaded file type
   if($extension=="jpg" || $extension=="jpeg") {
      $uploadedfile = $_FILES['image']['tmp_name'];
      $src = imagecreatefromjpeg($uploadedfile);
   }else if($extension=="png") {
      $uploadedfile = $_FILES['image']['tmp_name'];
      $src = imagecreatefrompng($uploadedfile);
   }else{
      $src = imagecreatefromgif($uploadedfile);
   }
   
   //creates a list of the width and height of the image
   list($width,$height)=getimagesize($uploadedfile);
   
   //adds color to the image
   $tmp = imagecreatetruecolor($newwidth,$newheight);
   
   //create image
   imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
   
   //set file name
   $filename = $filepath.$newimagename.".".$extension;
   $imagename = $newimagename.".".$extension;
   //uploads new file with name to the chosen directory
   imagejpeg($tmp,$filename,100);
   
   //empty variables
   imagedestroy($src);
   imagedestroy($tmp);
   
}


?>
Any help would be appreciated, fairly new to all this!

Thanks!!!

Hello,
Five images will be displayed inside a division.
There will be a previous and next button/link.
If someone click the next button the next image will be added in that div and the first image will be gone from that div.
The previous button/link will do the same thing.

Is it possible with php?
I am confused if it's a javascript or ajax question.

Thanks.
