ok. I have a variable that is actually a picture

I think that is what creates such a

$ Img = imagecreatefromjpeg ($ srcFile);

Now I would like to resize the image width to 550 but that does not lose the aspect ratio that need to remain the same.

Then the resulting image should be re-registered into a variable so the rest of the code could do the insertion of text and more.

Want to make site demotivation-fakeposters and others.

I found some code from Russians – everything work but the resize does not work so I wanted to with DataLife Engine and code that make the whole site will agree that the posters and where users will be able to generate and post.

here it is in (for all means not only reduces the images if they are huge)

There are some little hieroglyphs but this is due to the Russian Cyrillic alphabet.

    I think you mean ratio, where the greater of the x or y axis is used as the basis of the ratio: if (oldwidth > oldheight) ratio = newwidth / oldwidth else ratio = newheight / oldheight. You also need to consider a max allowable width and height for copied images. With PHP GD functions, this is done like so…

    $imageFilePath = '/original.jpg'; // path to original jpg
$imageSource = imagecreatefromjpeg($imageFilePath);
$newImageFilePath = '/new.jpg'; // path to new resized image name
$maxWidth = 100; // the max width you allow
$maxHeight = 100; // the max height you allow
$imgInfo = getimagesize($imageFilePath);
$originalWidth = (int) $imgInfo[0];
$originalHeight = (int) $imgInfo[1];
$originalType = (int) $imgInfo[2];
$conversionRatio = (($originalWidth > $originalHeight) ? $maxWidth / $originalWidth : $maxHeight / $originalHeight); // the important part
$newWidth = $originalWidth * $conversionRatio;
$newHeight = $originalHeight * $conversionRatio;
$newImage = imagecreatetruecolor($newWidth, $newHeight);
imagecopyresampled($newImage, $imageSource, 0, 0, 0, 0, $newWidth, $newHeight, $originalWidth, $originalHeight);
imagejpeg($newImage, $newImageFilePath);
