[RESOLVED] Image Resize

[The Little Guy]

Here is a resizing function That I found, and It isn't working correctly. Basically what it is doing is cropping the image, and making the bottom longer.

function createThumbnail($imageDirectory, $imageName, $thumbDirectory, $thumbWidth)
{
$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");
$origWidth = imagesx($srcImg);
$origHeight = imagesy($srcImg);

$ratio = $origWidth / $thumbWidth;
$thumbHeight = $origHeight * $ratio;

$thumbImg = imagecreate($thumbWidth, $thumbHeight);
imagecopyresized($thumbImg, $srcImg, 0, 0, 0, 0, $thumbWidth, $thumbHeight, imagesx($srcImg), imagesy($srcImg));

imagejpeg($thumbImg, "$thumbDirectory/$imageName");
}

createThumbnail("images/photos", "$name", "images/photos/thumbs", 100);

Should the last two args for the imagecopyresized be imagesx($srcImg), imagesy($srcImg)?

That ended croping, now it is just streching the file vertically. The original height is 599px, and it streches it to 5391px. What could be causing this?

I got it!
The problem was with the $ratio = ... it was reversed.

function createThumbnail($imageDirectory, $imageName, $thumbDirectory, $thumbWidth)
{
$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");
$origWidth = imagesx($srcImg);
$origHeight = imagesy($srcImg);

$ratio = $thumbWidth / $origWidth;
$thumbHeight = $origHeight * $ratio;

$thumbImg = imagecreate($thumbWidth, $thumbHeight);
imagecopyresized($thumbImg, $srcImg, 0, 0, 0, 0, $thumbWidth, $thumbHeight, imagesx($srcImg), imagesy($srcImg));

imagejpeg($thumbImg, "$thumbDirectory/$imageName");
}

createThumbnail("images/photos", "$name", "images/photos/thumbs", 100);
