[SOLVED] Help needed with Cropping

theCro · January 16, 2008

Hello everyone i've been using this php code to resize image 'on the fly' and it really rocks!

here's the code:

<?php
header ("Content-type: image/jpeg");
/*
JPEG / PNG Image Resizer
Parameters (passed via URL):

img = path / url of jpeg or png image file

percent = if this is defined, image is resized by it's
          value in percent (i.e. 50 to divide by 50 percent)

w = image width

h = image height

constrain = if this is parameter is passed and w and h are set
            to a size value then the size of the resulting image
            is constrained by whichever dimension is smaller

Requires the PHP GD Extension

Outputs the resulting image in JPEG Format

$img = $_GET['img'];
$percent = $_GET['percent'];
$constrain = $_GET['constrain'];
$w = $_GET['w'];
$h = $_GET['h'];

// get image size of img
$x = @getimagesize($img);
// image width
$sw = $x[0];
// image height
$sh = $x[1];

if ($percent > 0) {
    // calculate resized height and width if percent is defined
    $percent = $percent * 0.01;
    $w = $sw * $percent;
    $h = $sh * $percent;
} else {
    if (isset ($w) AND !isset ($h)) {
        // autocompute height if only width is set
        $h = (100 / ($sw / $w)) * .01;
        $h = @round ($sh * $h);
    } elseif (isset ($h) AND !isset ($w)) {
        // autocompute width if only height is set

$im = false; // If image is not JPEG, PNG, or GIF

[sAVE FILE AS 'imgsize.php']

BUT, i wanted to add new function so when, for example if the image is 600x500 and i want it to be 300x120 ... now it crops and STRETCHES the image and it's unproportional.. what i want is to make it proportional even if it's needed to cut the edges to fit the 300x120 pixels size... hopefully you understood what i wanted.. anyway the code for view image is

http://www.yourwebsite.com/imgsize.php?w=200&h=100&img=foto/enghrv2.jpg

i know i have to use http://bg2.php.net/imagecopy to crop the image as desired. but i do not know how to import it into my above posted code

someone please help, it's for my kid's soccer website, thanks alot! cheers!

Are you sure you mean you want to crop the image, or do you mean you want to resize it? They are different things.

Cropping actually removes part of the image, but the rest of it stays the same size as it was before (though the overall image becomes smaller as a result of some of it being removed).

Resizing is just taking an image and making it smaller, but keeping all of the original picture.

thanks for your time and your answer

here is real live example how i want it to work:

http://www.index.hr/thumbnail.ashx?o=c&w=220&h=100&path=images2/BracaMamicInx.jpg

change w=220 and h=100 hopefully youcan fill my code with code i need thanks man!

theCro · January 16, 2008

for example on the link i posted above if you change w= and h= it will change picture size right away to desired size and will crop the rest and again if you change the size, image stays the same.. try to look at http://www.index.hr/thumbnail.ashx?o=c&w=520&h=200&path=images2/BracaMamicInx.jpg

and change to http://www.index.hr/thumbnail.ashx?o=c&w=520&h=300&path=images2/BracaMamicInx.jpg and you'll see what am i talking about... waiting for your respond. thank you for your time!

You might try this script here

You might try this script here

http://mondaybynoon.com/2007/12/17/crop-and-resize-images-with-gd-or-imagemagick-v11/

just look at http://www.index.hr/thumbnail.ashx?o=c&w=220&h=100&path=images2/ivankoviccibalia-v.jpg and see what exactly i need and change w= and h= it's all on the fly...

theCro · January 17, 2008

ok i managed to modify my code now it looks like this:

	@ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $w, $h);

however, i'd like that it centers image then cut the edges ... please help!

theCro · January 17, 2008

sorry. the code i posted

@ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $sw, $sh);

only crop edges as desired but does not resize the image.. now i'm in total mess someone give me a hand please

theCro · January 17, 2008

ok it seems like it's all about

ImageCopyResampled ($thumb, $im, 0, 0, 0, 0, $w, $h, $sw, $sh); code

the problem is i dont know how t make it work with the code i posed on my first post (at the top of the page)

someone please solve this for me, i've been trying 4 days all day night long and came up with what i have now ... please someone help me here!

priti · January 17, 2008

what problem i was able see in your url was image was getting chopped off and shown to you. where as with that script the whole image was getting resized with out any cropping.

Regarding strected if you will try to give w,h greator then original only then it sud strected its size not in other case.

thank you for you beautiful code.. it actually crops it the good way, the only thing i now need is to resize it proportionally to weight size, and then crop the height (ALL CENTERED FOCUS)

as like on http://www.index.hr/thumbnail.ashx?o=c&w=250&h=450&path=images2/ivankoviccibalia-v.jpg it zoomed the center... and original image is 600x300 (http://www.index.hr/thumbnail.ashx?o=c&w=600&h=300&path=images2/ivankoviccibalia-v.jpg)

thanks and hopefully we will finish it! and make good script of it!

thanks !

this zoomed the center and cropped everything else outside 250x450.. this is what i need

thanks man for your time! i havent sleep 20 hours ,.. now i go to sleep hopefully when i wake up someone will solve my mystery

thanks to everyone!

can anyone try to modify this code so if original image is 600x300 and you resize it to 400x150 that it actually resizes it to weight=400 and CUT BOTTOM to fit height=150 .. of course with aspect ratio when resizing image.. .thanks alot please anyone!

//OUTPUTS A FILE THAT IS PROPORTIONALLY RESIZED TO 200px by X CALLED original.png (alternate way of accomplishing the above)
//print convert_img ("original.jpg", "original.png", "200", "", "", "");

//OVERWRITES THE ORIGINAL FILE AND RESIZES TO X by 200px
//print convert_img ("original.jpg", "", "", "200", "", "");

1. Configure the PHP file as instructed per the commented text

2. Put your pics in a directory called "images" on the same level as the php file

3. Create a new line to call the function in the php script at the bottom e.g.:

print convert_img ($_GET['img_start'], $_GET['img_end'], $_GET['w'], $_GET['h'], "", $_GET['crop']);

4. Call the script via a URL: http://www.yourdomain.com/convert.php?img_start=original.jpg&img_end=new.jpg&w=300&h=200&crop=yes (assumes you've named the php file "convert.php")

If you have a file called original.jpg in your images directory, the script will proportionally resize it to 300x200 and crop if necessary. The resulting file will be called new.jpg.

tried that, fixed all paths appropirately and it doesent work!

http://www.zadarsport.com/foto.php?img_start=acogov1.jpg&img_end=new.jpg&w=300&h=200&crop=yes shows nothing and new.jpg isnt created at all!

Should work...I've tested elsewhere. URL format is correct.

1. Where is your images directory? ...and what is your $img_path variable? The image you're trying to resize is not located at: http://www.zadarsport.com/images/acogov1.jpg

2. Have you changed the full $server_path variable -- not just the domain part? ...is it correct?

3. Are you 100% certain that ImageMagick is installed on your server? If so, have you changed the path accordingly?
