Too long compilation time

[simnalamburt]

Using all default features of image crate leads this crate to bloated compilation time which is undesirable. We should opt-in those featuers. Below codes are the brief example of how to do it.

[features]
## create a feature in your app
default = ["gif_codec", "jpeg", "ico", "png_codec", "ppm", "tga", "tiff", "webp", "bmp", "hdr"]

gif_codec = ["image/gif_codec"]
ico = ["image/ico"]
jpeg = ["image/jpeg"]
png_codec = ["image/png_codec"]
ppm = ["image/ppm"]
tga = ["image/tga"]
tiff = ["image/tiff"]
webp = ["image/webp"]
bmp = ["image/bmp"]
hdr = ["image/hdr"]

[dependencies]
image = { version = "0.10.0", default-features = false }

Isn't there a way to disable default cargo features and then enable them by adding a dependency to the library in the top project?

[simnalamburt]

@bvssvni It's possible but I intensionally choosed not to since it's unnecessary backward compatibility breakage.

[bvssvni]

Don't worry about breaking stuff! We'll just bump the version and existing code will continue to work with the old version.

[simnalamburt]

OK then. If we enhance documentations and examples, maybe it can be a good chance for texture_packer to be 1.0.0

I'll propose a PR soon.

[bvssvni]

We don't need 1.0.0 yet, 0.9.0 will work just fine because it is the first non-zero number that is interpreted as a breaking change by Cargo. However, it would be nice to do as you say.

Oops, sorry. That was a mistake
