image magick

I want to upload an image an resize as a thumbnail

Multiple formats .jpg, .gif, .bmp, .ttf etc...

I want to resize the image into a thumbnail that is within a maximum range like 200px width 200px height.

So if the image is a PORTRAIT form factor:
resize results = 200px height, *px width

If the image is a LANDSCAPE form factor
resize results = 200px width, *px Height

• = $variable_px < 200

I don't know how to call a command line function from php and get a result, could someone show me an example of how this is done?

**************My Form *********************
<FORM action=<?$PHP_SELF?>?action = upload method=post>
<input type=file>
<input type=submit>
</form>
**********My Form End***********************

**************My Desired Results *********************
Image is resized and placed into a folder called thumbnails
original image is saved into a folder called photos
***********My Desired Results End************************

I think I am suppose to use some function like exe(), or passthrough()

Thanks I am really struggling with this

why keep TWO copies of the image?

Can't you just resize if the person is looking at the "thumbnail" page?
It seems like a waste of memory to me.

In your script, if you need the image as a thumbnail, resize it in the
<img src=" " height=? width=?>

This reply is totally out of scope of the question, you are a total idiot and a waste of bandwidth

Why I need the original doesn't matter and obviously you have no clue hoe to pass between command line and php API

GO AWAY YOU LITTLE PEST!!!!

Just use the mogrify command from imageMagick:

//Maximum of 200px, will keep original
//dimension if less than 200px
mogrify -geometry 200x200 pic.gif

OR

//Force ('!') image to 200x200 regardless
mogrify -geometry 200x200! pic.gif

How do I do this? How do I pass the image to the command line? How does t return the result of the function? Can you show me an example?

Thanks

//Make sure your webserver has the read/write permission on the file, otherwise it won't work!

$img = '/path-to-img/mypic.gif';
$binpath = '/usr/bin'; //Where ever mogrify is
$cmd = "$binpath/mogrify -geometry 200x200 $img";
exec($cmd, $OutArray, $retValue);

First, what is bigger ? Width or height ?
Second, make a "rule of 3" (don't know exact term). Example...

function RD3($current_value, $max_img_size, $biggest_value) {
return (($current_value * $max_img_size) / $biggest_value);
}
$img_width = imageSX($image_file);
$img_height = imageSY($image_file);
$bgst_size = max($img_width, $img_height);
$new_max_width = 200;
$new_width = round(RD3($img_width, $new_max_width, $bgst_size));
$new_max_height = 200;
$new_height = round(RD3($img_height, $new_max_height, $bgst_size));
$source_im = createimagefromPNG|GIF|JPEG|...;
$new_im = createimage(200, 200);
imagecopyresampled($new_im, $source_img, 0, 0, 0, 0, $new_width, $new_height, $img_width, $img_height);
imagePNG|GIF|JPEG|...;
imagedestroy($source_im);

Hope it helped.
imagedestroy($new_im);

How do I find WHere mogrify is, I am on a virtual server

[Anon]

I still after all of these rsponses dont under stand how this works, cant be to difficult to explain

I pass the file to the script that calls IMAGEMAGICK function from an external application with exe()

So where does the file get placed after I resize it with IMAGEMAGICK?

[Anon]

With another program, Gif2png, which is used to convert gif images to png to help you to replace imagecreatefromgidf(), new images are in the path of the original image...

I figured this out on my own, here are some instructions for other like myself looking for a quick answer

You have your form

<?=$newname = date(mds)?>
<form ENCTYPE = "multipart/form-data" action="<?=$PHP_SELF?>" method=post>
<input type=hidden name=newname value="<?=$newname?>">
<input type=file name=userfile>
<input type=submit name=image>
<form>

You have this script that receives the form

//Step 1-This function will upload the file from the form
function do_upload($userfile,$newname)

{
global $new_file;
$new_file = "/home2/usr37/onlinedating-www/freesitesolutions/$newname.jpg";

if (!copy($userfile, $new_file)) echo "failed to copy file $userfile to $new_file\n";
return true;
}

do_upload($userfile, $newname);

// Step 2-This is how the file is passed from where it is located
$in_img = "/home2/usr37/online/$newname.jpg";

// This is the location of where the application is located on your server(imagemagick)
$convert = "/usr/local/bin/convert";

// Step 3-This is the location of where the new file will go after it is resized with new name thumb.jpg
$out_img = '/home2/usr37/online/'.$newname.'thumb.jpg';

// Step 4-This is the imagemagick function
$command = "$convert $in_img -geometry 200x50 $out_img";

//Step 5 this is the PHP function that actually passes the parameters to the application (imagemagick)
system( $command );

so now I have a new file called ****_thumb.jpg in my directory
