ksz2k / letter_avatar Goto Github PK

with ImageMagick 6.8.9-9 Q16 x86_64 2017-07-31, ubuntu 16.04.3 LTS

but after

with imagemagick: stable 7.0.7-28, macOS 10.13.3, LetterAvatar.resized files reminded under 10kb.

So I think it may be an issue with ImageMagick.

I'm not very good at English so sorry if there are any English syntax error.

I saw the main feature just execute ImageMagick convert to generate image.

But in README file you said:

sudo apt-get install -y advancecomp gifsicle jhead jpegoptim libjpeg-progs optipng pngcrush pngquant

The install way looks like tooooo hard.

If you remove ImageOptim, it will easily.

Hi @ksz2k, thanks for your share first. when i try it , i meet a problem about utf-8 character generating.

Test Case: LetterAvatar.generate "宋佳洋", 200
Result:

Does it really support or my ImageMagic version problem?

Version: ImageMagick 6.8.9-7

Howdy
I am using Rails 5.0.4

LetterAvatar.generate 'ksz2k', 200 is working just fine. (This is what I get in the rails console)

[2] pry(main)> LetterAvatar.generate 'ksz2k', 200
=> "public/system/lets/letter_avatars/2/K/87_178_230/200.png"

However when trying to use the HasAvatar helper I get the following error

[4] pry(main)> LetterAvatar::HasAvatar
NameError: uninitialized constant LetterAvatar::HasAvatar

Any ideas on what could be going on here?

Since I would like to avoid the dependency on AS, let's rewrite the code to not depend on AS.

> require 'letter_avatar'
NoMethodError: undefined method `mattr_accessor' for LetterAvatar:Module
    from /home/vagrant/.gem/ruby/gems/letter_avatar-0.1.7/lib/letter_avatar.rb:7:in `<module:LetterAvatar>'
    from /home/vagrant/.gem/ruby/gems/letter_avatar-0.1.7/lib/letter_avatar.rb:5:in `<top (required)>'
    from (irb):2:in `require'
    from (irb):2
    from /usr/bin/irb:11:in `<main>'

This is my initializer:

LetterAvatar.setup do |config|
    config.fill_color        = 'rgba(255, 255, 255, 0.65)' # default is 'rgba(255, 255, 255, 0.65)'
    config.cache_base_path   = 'public/system/ava'     # default is 'public/system'
    config.colors_palette    = :iwanthue                # default is :google
    config.weight            = 96                      # default is 300
    config.annotate_position = '-0+5'                  # default is -0+5
    config.letters_count     = 2                        # default is 1
    config.pointsize         = 140                       # default is 140
end

And this is how I generate avatar:

LetterAvatar.generate name, 96

And this is the result for dev and prod:

I have no idea whey production makes letters almost invisible and tiny. Any idea?

Update:

If I gave weight 500 and pointsize 200 this happens in dev and prod:
