PHP - Tiff Layer To Gd Image

Hello guys,
I want to build my own Database Class with PDO. This Class should extend the PDO Methods. I heard that i should create an abstraction layer and two different Classes, is that right? First Class should do the connection and the second class has the new methods.

My Database Class should have the following methods
     - select
     - insert
     - update

Access like:
$db->select ($table, $data) { }
$db->insert($table, $data) { }
$db->update($table, $data) { }


I dont know, how i should begin... i know how i can create a PDO Connection, but i haven't a idea how i can do a abstraction layer with PDO...

please help me:(


 I heard that i should use a abstraction layer. One Class for the connection and one class for the methods.

Here is the code I have right now:

<?php
header('Content-type: image/png');

$grey = new ImagickPixel('#ebebeb');
$orange = new ImagickPixel('#0f92d6');

$image = new Imagick('assets/lop.png');
$layer = new Imagick('assets/lop-base.png');
$layer->thumbnailImage(200, 0);
$image->thumbnailImage(200, 0);

$layer->paintOpaqueImage($grey, $orange, 100);

// Place layer on image
$image->compositeImage($layer, Imagick::COMPOSITE_SOFTLIGHT, 0, 0);

// Let's merge all layers (it is not mandatory).
$image->flattenImages();

echo $image;

?>

It's putting the layers on top of eachother very nice. The thing is is that this involves some heavy shading at times depending on the bunny breeds.   Here is what the base image ($image) looks like:     And here is what the overlay ($layer) looks like:     This is what the outcome looks like versus the intended result:       I've tried almost all of their composite constants.. I can't figure out how to do this or the best way of going about it. Because the colors are going to be dynamic throughout the site so I can't just save a .png of every color combination.. and there will be more colors layered on top of eachother like markings/patterns/etc.   Thanks for any help!

I want when onmouseover on particular section to put an OPACITY #fff 0.2 layer on everything except the selected class i.e. table Similarly as you have: .tableHighlight:hover{background-color:#eee}
<table id='table-main' class='tableHighlight'>
... but inversed (puts layer on everything else, but not the table itself)   --- http://jsfiddle.net/LYcm9/1/

Visit: http://testowa.testy...e/testy-na-mocz (the behavior is going crazy). Has anybody got maybe any clue on how to fix it to work correctly?   Code itself. http://jsfiddle.net/LYcm9/5/

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).

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

require_once('storescripts/connect.php');
mysql_select_db($database_phpimage,$phpimage);
$uploadDir = 'upload/';
if(isset($_POST['upload']))
{


foreach ($_FILES as $file)
{

    $fileName = $file['name'];
    $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;
}
}

$mid   = mysql_real_escape_string(trim($_POST['mid']));
$cat   = mysql_real_escape_string(trim($_POST['cat']));
$item  = mysql_real_escape_string(trim($_POST['item']));
$price = mysql_real_escape_string(trim($_POST['price']));
$about = mysql_real_escape_string(trim($_POST['about']));

$fields = array();
$values = array();
$updateVals = array();
for($i = 0; $i < 4; $i++)
{
    $values[$i] = isset($file_names[$i]) ? mysql_real_escape_string($file_names[$i]) : '';

    if($values[$i] != '') {
        $updateVals[] = 'name' . ($i + 1) . " = '{$values[$i]}'"; 
    }
}
$updateNames = '';
if(count($updateVals))
{
    $updateNames = ", " . implode(', ', $updateVals);
}

$update = "INSERT INTO image
               (mid, cid, item, price, about, name1, name2, name3, name4)
           VALUES
               ('$mid', '$cat', '$item', '$price', '$about', '$values[0]', '$values[1]', '$values[2]', '$values[3]')
           ON DUPLICATE KEY UPDATE
                cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames";
$result = mysql_query($update) or die (mysql_error());

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.

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 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,
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,
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.

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!

This resizer works fine except I would like it to save the original image AND the thumbnail.  Right now its only saving the cropped thumbnail.  It's seems simple enough but I've tried several different ways but can't get it to work. :(
