870210 - Extend node-hubble to allow discovery of image sizes

Status: RESOLVED FIXED

Description

[David Humphrey (:humph)]

We would like to know when to use an image based on its size, when to crop it, etc.  Hubble is a perfect candidate for this.  I've written the code and tests, just need to fixup the readme, then I'll get this into review.

The code looks very sane to me, but I'm getting test fails when running locally. Specifically:

1) should give proper sizes for JPEG files
2) should give proper sizes for GIF files

And assertion errors on status codes. This leaves me thinking I'm somehow missing a dependency for the tests? I'm unsure, but everything I needed installed successfully with npm.

Take a look at your node_modules/canvas/build/canvas.target.mk, and see if gyp found the right deps.  It should have defined HAVE_JPEG and HAVE_GIF.  Here's what I have after I build:

DEFS_Release := \
	'-D_DARWIN_USE_64_BIT_INODE=1' \
	'-D_LARGEFILE_SOURCE' \
	'-D_FILE_OFFSET_BITS=64' \
	'-DHAVE_FREETYPE' \
	'-DHAVE_JPEG' \
	'-DHAVE_GIF' \
	'-DBUILDING_NODE_EXTENSION'

Yeah, I'm missing JPEG and GIF from that list. Rather than poke around more I'll let :jbuck look at it. Code R+ from me.

Kind sir, a moment of your time?

r+, although I'm not a huge fan of the node-canvas dependency. It'd be nice to have something pure JS... if only we had unlimited time!

The node-canvas dep isn't a big deal for a server.  Basically, once it's doable in JS, node-canvas will switch to it too, so we'll all be happy.
