Is is possible to add a border to an image using GD..

What I simple want to do is add a 1px border around images.. searched google but couldnt find nothing

Thanks
James

why not just use a css script?

Because what im doing is creating dynamic images which people need to link to.. so cant use css

Can you show us the code or an example?

I think what James is asking for is the code to do so. I am equally interested in any good GD information resources anyone may have.

Yea I was wanting the code for how to do it..

Ive looked everywhere and since no-one has posted I quess its not possible..

But ive thought of a work around..

Get the size of the image.. Then create an image 2px wider and 2px taller and then merge the two images together so there is a 1px border around the image..

Got the basics just need to perfect it now

I am not familiar with GD to a great extent but it seems to me that this would be a logical solution...

Create the image with GD and cache it so that you don't have to create it every single page load. Then when calling the image simply add the border attribute to the img tag.

This works:

PHP Code:

<?php

$img = ImageCreateFromJPEG('img.jpg');

// Draw border
$color_black = ImageColorAllocate($img, 0, 0, 0);
drawBorder($img, $color_black, 3);


// Output
header('Content-type: image/jpeg');
ImageJPEG($img);



// Draw a border
function drawBorder(&$img, &$color, $thickness = 1)
{
    $x1 = 0;
    $y1 = 0;
    $x2 = ImageSX($img) - 1;
    $y2 = ImageSY($img) - 1;

    for($i = 0; $i < $thickness; $i++)
    {
        ImageRectangle($img, $x1++, $y1++, $x2--, $y2--, $color_black);
    }
}

?>

You can change the type of image by using different ImageFrom* and Image* functions (be sure to change Content-type), but everything else should work.

Thanks
