Answered phpthumbof: How to achieve max height / max width on varying image sizes.

I have 3 different types of images that need resizing.

Landscape, Portrait and Square.

I'm using phpthumb on a portfolio page quite effectively (because the columns are a fixed width): For example:
[[+image:phpthumbof=`w=300&zc=1`]]

However when you click through from an image on the portfolio page, I want the images to display larger.

I want to use some logic like:

• if landscape image > no bigger than width 'x', height 'auto'
• if square image > no bigger than width 'x', height 'auto'
• if portrait image > no bigger than height 'x', height 'auto'

I've been reading through:
http://phpthumb.sourceforge.net/demo/docs/phpthumb.readme.txt
http://rtfm.modx.com/display/ADDON/phpThumbOf

However, the parameters in the text file don't seem to work as indented:
[[+image:phpthumbof=`&hp=500&wl=750&ws=500`]]

Square & portrait images have white space included in the image left and right, as if the rule above is conflicting.

Any experience with Phpthumb or advice?

Do you need to include &zc=something as well as setting the portrait height/landscape width.

Are the portrait images all uniform size, ie - can you set &pw= on them? Same goes for landscape height, if portrait height is 500, then landscape height max is 500 too?

I'll try out on an install and see what I can get.

Hey pdincubus - I don't really want to zoom crop the images.

Quick explanations to the values in my call:
[[+image:phpthumbof=`&hp=500&wl=750&ws=500`]]

hp = max height of portrait images
wl = max width of landscape images
ws = max width of square images

I've found a temporary solution by just setting a fixed height (no width), but the portrait and square images suffer a little because of this.
