PHP - Want To Resize Font-size With Php !

Hi All,

Just wondering whether it is possible to resize a jpg image to a specific size in bytes (while preserving height/width ratio).

Thanks for any clues!

Hi there,

In a string for a shopping cart I am storing both the item id and the item size selected in a number like this 12s1 where 12 is the id and 1 is the size.

How can I separate these from one another again? I'm guessing it's to do with expand() ?

Thanks,

Jack

Hi guys, i have a form that uploads a school photo.

All i want to do is resize the image to its widest dimension of a width of 480 px and then obviously constrain the height.

can anyone help me, ive tried to do this myself but when it comes to image properties i really struggle etc.

heres my upload code.

Code: [Select]

I want to set the size to 100 x 100, which part of the code that I need to edit?

Hi,

I'm having to look hard for the right way to do this.

Basically the image is sent to the database, and is called to be put in a table, but the images are all different sizes, i would like them all one size, whats the best way to do this with my existing script:

Code: [Select]
<?php 
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 echo '<pre>' . print_r($_FILES, true) . '</pre>';

 
 //This is the directory where images will be saved 
 $target = "/home/users/web/b109/ipg.removalspacecom/images/COMPANIES"; 
 $target = $target . basename( $_FILES['upload']['name']); 
 
 //This gets all the other information from the form 
 $company_name=$_POST['company_name']; 
 $basicpackage_description=$_POST['basicpackage_description']; 
 $location=$_POST['location']; 
 $postcode=$_POST['postcode'];
 $upload=($_FILES['upload']['name']); 
 
 // Connects to your Database 
 mysql_connect("***", "***", "***") or die(mysql_error()) ; 
 mysql_select_db("***") or die(mysql_error()) ; 
 
 //Writes the information to the database 
 mysql_query("INSERT INTO `Companies` (company_name, basicpackage_description, location, postcode,  upload) VALUES ('$company_name', '$basicpackage_description', '$location', '$postcode',  '$upload')") ; 
 echo mysql_error();
 
 //Writes the photo to the server 
 if(move_uploaded_file($_FILES['upload']['tmp_name'], $target)) 
 { 
 
 //Tells you if its all ok 
 echo "The file ". basename( $_FILES['upload']['name']). " has been uploaded, and your information has been added to the directory"; 
 } 
 else { 
 
 //Gives and error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 
 ?>

I did a tutorial on uploading a profile pic and also did a tutorial on an image re-size class. The only thing is the tutorial on the re-size class is done without using a form which is pointless. Can someone help me integrate this into the profile pic tutorial? Here's a link to the re-size tutorial.

Warning: unlink((R)Photo-0027.jpg) [function.unlink]: No such file or directory in /home/bumwarsc/public_html/images.php on line 126

I want to resize an image to fit within a rectangle.

Lets say my rectangle is 400 wide and 200 tall.

My image is 300x300.

It should take, and make the rectangle 200 tall, then scale the width accordingly.

I wrote a function a while back that resizes inside a square, but that was a little easier, since you know to constrain by height if height is greater than width, and to constrain by width if width is greater than height.

$w = $stats[0];

$h = $stats[1];

if($dim){ // constrain image

if($w > $h){

$h = ($h / $w) * $dim;

$w = $dim;

} else {

$w = ($w / $h) * $dim;

$h = $dim;

}

}


Thats my code to constrain inside a box. It gets the starting h and w from $stats, which is loaded from getimagesize. Then it sets a new h and w based on dim, which is the size of the box.

The new version will need dimW and dimH, instead of just dim.

Can anyone help me out?

I am looking for a script that can change the width and height of an image when it is uploaded to our web site through a web form. Any help would be great.

Alright guys, i have been looking for a simple script for this online to try get my head around it.

Hi!

I'm looking for a script that can do the following:

upload one or preferably fx. five image files(jpg)

resizes them to a specific size if they exceeds that size.

create a thumbnail

No files above 100kb can be uploaded.

uploaded and/or processed files must be renamed with a unique file name.

Work with php5


I have searched the internet for a script like that, but I can't find one that matches my needs. Also, the code must include good comments and nott be to hard to understand. So as basic code as possible.

Please help me!!!!

How can I resize an image that i'm showing and rather than saving it, just output the file?

And would this vary if I was to be first calling the image through AJAX?
