Google App Engine Images API - cropping using a bounding box with percentages

Question

In the python google.appengine.api.images docs there are crop functions such as crop(left_x, top_y, right_x, bottom_y) , which allow you to specify a bounding box for cropping using percentages .

In addition, same docs say that one can append eg '=s32' to the image url returned by get_serving_url() in order to resize the image to 32px in the larger dimension. There are also crop options, however none of them are given with a bounding box (ie crop that's not defined from the corner nor around the center of the image) nor with percentages (all examples are around pixels).

Is there a way to replicate crop() 's behavior by appending options to the serving url returned by the get_serving_url() function?

Answer 1

According to Google's support, unfortunately it is not possible to crop a bounding box via serving_url as stated here .

Another point to consider is that their documentation of serving_url only support size and crop parameters only, but it works with a lot more options , so there is a possibility that it works as well, just be in mind that officially not.

And please, if you success on that, don't forget to share it here!
