What happens with portrait images? new!

Hi,

Before I build the class into my website, I would like to know what happens when resizing a portrait image. Reading the documentation, it seems that any image will be resized to the value of image_x. This would mean that it gets the same width as a resized landscape picture, resulting in different formats. E.g. if image_x is 400, a landscape image of 1024x768 would be resized to 400x300, but a portait image of 768x1024 would become 400x533, where it should actually be 300x400.

Am I right here? Or are the width and height automatically swapped to give the desired result?Reply

You can set image_x and image_y at the same time, using image_ratio. The image will then be resized to fit within the two dimensions, maintaining aspect ratio and orientation.

For instance:
$foo->image_ratio = true;
$foo->image_x = 400;
$foo->image_y = 400;
will resize your images so that they fit within 400x400:
1024x768 resized to  400x300
768x1024 resized to  300x400

See this thread or this other one which describes a more advanced method.

Note that you can also use image_ratio_crop instead of image_ratio. That would then make the image to be exactly 400x400, maintaining aspect ratio, and discarding excess image. Try it to see what it does. You can also try image_ratio_fill, which is more similar to image_ratio.Reply
