Templates provide an easy way to create and customize a display. WellLog widget-based applications can use templates in JSON format to specify the properties of tracks, curves and other objects.
GeoToolkit provides a basic template which can be re-used. The user can also implement their own custom format or convert old templates, but these are outside the scope of this tutorial.
Please refer to the Welllog Architecture overview in the Programmer's Guide for more details on templates.
# Loading a Template
The following code shows how to load a template. The modified JSON schema, found in jschema.json, is based on www.jsonschema.net . It has two linear tracks and one custom track with one curve each and two index tracks. It provides references to the curves but the users have to provide location of the datasource. Data binding is used for data connection with the template. Please refer to the Data Connection tutorial for more details.
import { Plot } from "@int/geotoolkit/plot/Plot.ts";
import { HeaderType } from "@int/geotoolkit/welllog/header/LogAxisVisualHeader.ts";
import { registry } from "/src/code/WellLog/DataAndTemplates/Templates/createRegistry.ts";
import { template1 } from "/src/code/WellLog/utils/templates/template.js";
import { createWellLogWidget } from "/src/code/WellLog/utils/common.ts";
const createScene = (canvas) => {
const widget = createWellLogWidget().setAxisHeaderType(HeaderType.Simple).setDataBinding(registry).loadTemplate(JSON.stringify(template1));
return new Plot({
"canvaselement": canvas,
"root": widget
});
};
export { createScene };
createScene(document.querySelector('[ref="plot"]'));
# Loading a Template with Patterns
The template doesn't have embedded pattern images. The template only keeps the names of the patterns and requires specifying locations of patterns. The following code shows how to load a template with patterns.
