could someone help please

[justAnoob]

this is driving me crazy. all i'm looking to do is if the image height is taller than its width, set the height to 380 and the width to the correct ratio

 

and if the width is wider than the height, set the width to 380 and the height to the correct ratio

Does this look like i'm getting close?

list($width_orig, $height_orig) = getimagesize($newname);

$ratio_orig = $width_orig/$height_orig;     

if ($width/$height > $ratio_orig) {  
   $width = $height*$ratio_orig;
} else {
  $height = $width/$ratio_orig;
}

I think this is what you're looking for.

 

list($width,$height) = getimagesize($newname);  
if($height > $width) {  
$ratio = $width/$height;
$height = 380;
$width = $height*$ratio;
}
else {
$ratio = $height/$width;   
$width = 380;
$height = $width*$ratio;
}

[crabfinger]

or you could get fancy and do this

 

list($width,$height) = getimagesize($newname);  
list($width,$height) = $width > $height ? array(380,380 * ($height / $width)) : array(380 * ($width / $height),380);

[justAnoob]

on that first post which heights and widths are from the orginal image

 

kinda need to know because

 

imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

[crabfinger]

Sorry all I saw was unnecessary variables but I guess they aren't

 

list($width_orig,$height_orig) = getimagesize($newname);  
if($height_orig > $width_orig) {  
$ratio = $width/$height;
$height = 380;
$width = $height*$ratio;
}
else {
$ratio = $height/$width;   
$width = 380;
$height = $width*$ratio;
}

[justAnoob]

image width is still getting stretch out to 380 even if the height got scaled to 380

 

the width should be smaller,

[crabfinger]

Sorry brain fart

 

if($height_orig > $width_orig) {  
$ratio = $width_orig/$height_orig;
$height = 380;
$width = $height*$ratio;
}
else {
$ratio = $height_orig/$width_orig;   
$width = 380;
$height = $width*$ratio;
}

[justAnoob]

that works great, actually i changed the 380 to 90  for my thumbnails,  now the problem is resizing the full size image that also gets uploaded. i tried duplicating the actions for the full size image, but things go screwy. Here is what I'm trying  (making the thumbnails now bigger than 90 for width or height, and full size images no bigger than 380 for width and height.  Anyone know?

Here is the whole script, I'm stumped.

<?php

$ext = substr($str,$i+1,$l);

	$extension = strtolower($extension);
	if (($extension != "jpg") && ($extension != "jpeg"))
	{
		// error

	}
	else
	{
		$size=filesize($_FILES['image']['tmp_name']);
		if ($size > MAX_SIZE*2048)
		{
			// error

the resize of the thumbnail (90) works good on its own, but the way i have it above (with the full size imaged resized to 380), them both together create the problem.

[crabfinger]

Try this out

 

// Get new dimensions
list($width_orig, $height_orig) = getimagesize($newname);
// Thumbnail
if($height_orig > $width_orig)
{
$ratio = $width_orig/$height_orig;
$height1 = 90;
$height2 = 380;
$width = $height*$ratio;
$width2 = $height2*$ratio;
}
else
{
$ratio = $height_orig/$width_orig;
$width = 90;
$width2 = 380;
$height = $width*$ratio;
$height2 = $width2*$ratio;
}

// Resample
// Thumbnail
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($newname);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// Full size image
$image_p2 = imagecreatetruecolor($width2, $height2);
$image2 = imagecreatefromjpeg($newname); 
imagecopyresampled($image_p2, $image2, 0, 0, 0, 0, $width2, $height2, $width_orig, $height_orig);

Thanks crabfinger, I'll give it a shot when I get home from work. 

[justAnoob]

well, I'll gave it a shot and the full size image is not reduced.  The script below does everything great for creating the thumbnail,, still looking for an answer to get the full size image scaled down to 380, meaning the height or width is a max of 380 and the the aspect ratio remains intact.

Try this

 

// Resample
// Thumbnail
print 'Thumbnal<br />-----';
print 'New Width: ' . $width . "<br />";
print 'New Height: ' . $height . "<br />";
print 'Original Width: ' . $width_orig . "<br />";
print 'Original Width: ' . $height_orig . "<br />";
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($newname);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);
// Full size image
print 'Full Size Image<br />-----';
print 'New Width: ' . $width2 . "<br />";
print 'New Height: ' . $height2 . "<br />";
print 'Original Width: ' . $width_orig . "<br />";
print 'Original Width: ' . $height_orig . "<br />";
$image_p2 = imagecreatetruecolor($width2, $height2);
