Requirements

  • Wagtail >= 2.7

  • Django >= 2.0

Installing

Install using pypi

pip install wagtailannotatedimage

Using

Extend the BaseAnnotationForm to define what data should be stored with annotations. AnnotationsField stores the annotations data as json, converting to a dict on retrieval.

from django import forms
from django.db import models
from wagtail.wagtailcore.models import Page
from wagtailannotatedimage.edit_handlers import AnnotatedImagePanel
from wagtailannotatedimage.fields import AnnotationsField
from wagtailannotatedimage.forms import BaseAnnotationForm

class AnnotationForm(BaseAnnotationForm):
    title = forms.CharField()
    about = forms.TextField()

class TestPage(Page):
    image = models.ForeignKey('wagtailimages.Image', blank=True, null=True,
                              on_delete=models.SET_NULL, related_name="+")
    annotations = AnnotationsField(blank=True)

    content_panels = Page.content_panels + [
        # First parameter - name of the image field
        # Second parameter - name of the annotation field
        # annotation_form - optional, the form used for annotations if you need to store data for each point
        AnnotatedImagePanel(
            'image', 'annotations',
            annotation_form=AnnotationForm(), heading='Annotated Image'
        )
    ]
<div class='image-container'>
    {% image page.image('width-500') %}

    {% for annotation in page.annotations %}
    <div
        class='annotation'
        style="left: {{ annotation.x * 100 }}%; top: {{ annotation.y * 100 }}%;"
    >
        <h3>{{ annotation.fields.title }}</h3>
        <p>{{ annotation.fields.about }}</p>
    </div>
    {% endfor %}
</div>
.image-container {
    position: relative;
}

.image-container > img {
    width: 100%;
    height: auto;
}

.annotation {
    position: absolute;
}
