Image Creation with TTF fonts

[rizza]

Anybody got any good resources for using TTF files in image creation??

I'me trying to figure out things like what dir i can put these TTF files in and how does this affect the server and stuff like that.


Also anybody used PHP to make thumbnails and re-size images to the same size, or add watermarks? Any nifty scripts like that would be cool.

Thanks in advance to all who can help,

Rizza

This script template will create a simple image with some TT text in it:

<?php
$im = imagecreate (<imagewidth>, <imageheight>);
$background_color = imagecolorallocate ($im, <redvalue>, <greenvalue>, <bluevalue>);
$fontcolor = imagecolorallocate ($im, <imageredvalue>, <imagegreenvalue>, <bluevalue>);
imagefill ($im, 0, 0, $background_color);
imagettftext ($im, <fontsize>, 0, <x_coord>, <y_coord>, $fontcolor, <fontfilename>, <text>);
header (&quot;Content-type: image/png&quot;);
imagepng ($im);
?>

There are some other useful functions, like imagettfbbox(), which will return a bounding box the surrounds some given text in a given font. Take a look in the Image family of functions for more information (

http://www.php.net/manual/en/ref.image.php)

As far as where the fonts can be stored, that is anywhere on the filesystem that permissions allow the user as which PHP runs to read the file.

I have never done image resizing or thumbnailing. Watermarks can be done using transparent colors.

If you're looking for scripts, do what I do -- ask Google. Want the best answers? Ask the best questions:

I've used PHP to resize and create thumbnails of images. Here is the part of the script that does the thumbnailing:

if (!($srcImg = ImageCreateFromJPEG($filename)))
	die("Not a valid JPEG image.");
if (ImageSX($srcImg) > 200) // Only make thumbnails of images that has a width greater than 200 pixels
{
	$origwidth = ImageSX($srcImg);
	$origheight = ImageSY($srcImg);
	$scale = 200 / $origwidth;
	$height = $scale * $origheight;
	$width = $scale * $origwidth;
	$dstImg = ImageCreateTrueColor($width, $height);
	ImageCopyResampled($dstImg, $srcImg, 0, 0, 0, 0, $width, $height, ImageSX($srcImg), ImageSY($srcImg));
	ImageJPEG($dstImg, './thumbs/' . $img . '.jpg');
	ImageDestroy($dstImg);
}
ImageDestroy($srcImg);
