Outdated examples: can't draw text on an image

[YassinEldeeb]

Using this example causes the following errors:

Seems to work with image = "0.23.14" (but not with the most recent 0.24.x release)

@gregoa Thank you for mentioning a working version, It's a good solution to downgrade at least for now.

image = "0.24.0" imageproc = { git = "https://github.com/image-rs/imageproc.git" }

after downgrading the version of image to 0.23.14, it doesn't work for me. i got the same error as you. image = "=0.23.14" imageproc = "0.22"

it works as follow

image = "0.24.1" imageproc = { git = "https://github.com/image-rs/imageproc" }

When specifying version imageproc = "0.22.0", it seems drawing/mod.rs does not export text_size. It becomes:

mod text;
pub use self::text::{draw_text, draw_text_mut};

However, the example requires text_size and the latest master contains it.

Is 0.22.0 outdated? Is there a newer version or a pre-release version?

[qqpann]

image = "0.24.0" imageproc = { git = "https://github.com/image-rs/imageproc.git" }

For now this works for me, as 0.22.0 seems to be outdated.

This is fixed in version 0.23, which I've just published
