Google HPIS don't animate gifs

Question

I'm using Google Cloud Platform (App Engine). I have a High Performance Image Store [HPIS] url for an animated GIF (example below). I know there are some URL arguments you can provide to manipulate the image, eg =s1600 or =s128-c.

I was wondering if there's an argument to prevent a GIF from animating. Maybe just showing the first frame of the GIF or something. Also, what other arguments are out there?

Answer 1

Over the years I've been able to uncover the following "extra features" that HPIS has to offer... the option you want is -k which will stop the animation:

-bXX           -- border pixel size (border color depends on image color?)
-c             -- crop center
-hXXXX         -- height
-h             -- (without XXX) puts white padding around border
-d             -- download
-g             -- Google+ panorama XML?
-k             -- stop animation
-n             -- crop from... somewhere between top and center?  (requires -hXXX -wYYYY)
-p             -- crop from top?
-rXXX          -- rotate in degrees (90/180/270)
-sXXXX         -- size to best fit
-wYYYY         -- width
-v[0|1|2|3]    -- quality level/file size (highest to lowest)


Other combos:  -hXXXXX-wYYYY-s  -- stretch to fit (only some images will stretch?)

would love to hear from anyone else that has uncovered more of these gems?
