Image Border Create

[EZE]

How what function do i use to create a solid 1px black border around a pre-existing image? I researched GD library, and nothing really made sense. Can someone help please?  ??? ??? ???

wont CSS do?

border:1px solid #000

just use CSS, unless you want the border to be apart of the image.

then

[code]// Create border around image
imageline($image, 0, 0, 0, $imgHeight, $colorGrey);
imageline($image, 0, 0, $imgWidth, 0, $colorGrey);
imageline($image, $imgWidth-1, 0, $imgWidth-1, $imgHeight-1, $colorGrey);
imageline($image, 0, $imgHeight-1, $imgWidth-1, $imgHeight-1, $colorGrey);[/code]

If you mean to the actual image itself, try http://www.php.net/manual/en/function.imagerectangle.php or make the image a few pixels bigger, use http://www.php.net/manual/en/function.imagefill.php, then import the picture and offset it a pixel or two.

Okay, I tried [code]<?
imagerectangle(image.png, 0, 0, 149, 171, #000000);
?>[/code], but it said this: [quote]
Parse error: parse error, unexpected ';' in /home/content/e/z/e/ezevolk/html/tests/image_functions/index.php on line 3
[/quote] What did I do wrong?

[Jessica]

image.png needs to be a string, surrounded with ''
'image.png'

[EZE]

I did that, and the same error comes up. Do I have to add single quotes around the color too?

[The Little Guy]

yes, because the pound sign isn't a number

[Jessica]

Yeah.

Now it says this [quote]
Warning: imagerectangle(): supplied argument is not a valid Image resource in /home/content/e/z/e/ezevolk/html/tests/image_functions/index.php on line 2
[/quote](Also, thank you for helping me with this!)

You don't give the image functions the filename, you give them a file handle. E.g:
[code]
$im = imagecreatefrompng( 'image.png' );
$black = imagecolorallocate($im,0,0,0);
imagerectangle($im, 0, 0, 149, 171, $black);

//WARNING, THIS WILL OVERWRITE THE ORIGINAL!!
imagepng($im,'image.png');
[/code]

The above code should create the border and overwrite the old file with the new image.

Cool! That worked! Now, if my image is 149 by 171, should i set the finishing x and y positions to be that? Because I did, and the image's border cut off in the bottom and right sides of the image, they didn't show up at all. Do I have to subtract 1 from each finishing coordinate?

[ShogunWarrior]

Yep, subtract 1 from the width and height.

Okay, thank you. What if I wanted to expand the image by 1px on all sides, leaving blank pixels, not stretching out the image, then applying the border. For example, i have a 50 by 50 image, and i draw a 1 px border all the way around it, and the border expands the image size, but the image stays the same. Pretty much like adding a css border.
