ANNOTATE GEM UPDATE
To update the text in an existing label, click on the pencil icon on the annotation. The created annotation is added to the anno object as anno.addAnnotation(annotation). Also, you can see that I also added the primary key of the label to the geometry of annotation as label_id. Notice that we created a hash of annotations data from the database and used that hash to create annotations. Image_annotater/db/migrate/20190123073338_create_items.rb class CreateItems ) The model migration must have the following fields: rails g model ItemĪlso, add the following line to the routes.rb resources :items
I am not going to the details of carrierwave implementation. Add the following lines to GemFile: gem ‘carrierwave’, ‘~> 0.11.2’ gem ‘mini_magick’, ‘~> 4.8’ MagickCore/annotate -private.h MagickCore/attribute.h MagickCore/cache-private.h MagickCore/image-private.h MagickCore/pixel-accessor.h MagickCore/gem.h. For that, we can use the carrierwave gem. The goal is to create multiple labels on an Item image. Our app should contain two tables an Item table to store various Images and a Labels table to store the annotations. Type in Terminal: rails new image_annotater Let’s quickly set up our app and back-end. Since I’m more comfortable in rails, we’ll be building a rails app. Annotorious is a javascript library that can be used with any back-end frameworks. The annotate gem will add a comment to the top of some selected files describing the database schema relevant for those files including field names, index configuration and foreign keys.

In this piece, we will be building an image annotation app that lets you mark and save annotations on a given image. For plants, users may instead use the Annotate Plant Enzymes with.
