get nonoriginal image sizes through API?

Question

There are approximate image sizes, it's possible to request a custom size, but.. no way to get the exact size.

I'd like to call something like images.getEXIF or images.get or images.getURLs. Give an image id/key, tell it "medium", and get back the exact dimensions (perhaps 600x200 or 600x450 or 200x450, all of which are valid as a medium). It's easier than downloading the image, which I don't need to do.

Answer 1

In our next version of the API, we plan on returning an ImageURL object that includes dimensions rather than just a URL string.

In the meantime, you can use the Height and Width of the original image to calculate what the dimensions of a given display copy will be based on the number of pixels on the longest size.

eg...

1. If I have an original portrait image that is 2336x3504, the Medium image will be 450 pixels high.

W = 2336 x 450 / 3504 = 300

Medium = 300x450px

1. If I have an original landscape image that is 5634x3753, the Medium image will be 600 pixels high

H = 3753 x 600 / 5634 = 400

Medium = 600x400px

Answer 2

How about a petition to add 'ratio' to the 1.3 API for select requests? Logic to calculate image size could then easily be made at our end... I would imagine this addition to be perhaps the simplest ever to integrate? :)

Answer 3

David, seems that for 100x100 and 150x150 resolutions logic that you provide does not come true. They are always squares. Am I right and are there any other exclusions of that rule ?
