APP Control

This is APP Control of the Image Analysis module. From here the advanced features of the Image Analysis module are available.

APPs are the center of the Image Analysis module where APP is an abbreviation for Analysis Protocol Package. Running an APP requires minimal training and prerequisite knowledge about Visiopharm and its features.

In APP Control, the details of the APP can be configured. This provides control over the pre- and post-processing steps applied before and after the classification method, respectively, and determines which calculations should be the output of the APP.

Customizing APP Images and Descriptions

In the APP Selection view, hovering over an APP displays a pop-up containing an image and a description of the APP. This information helps users understand the purpose of the APP, its inputs and outputs, and which other APPs it is commonly used with.

When creating or modifying an APP, it can be a good idea to add both an image and a description. This makes the APP easier for other users to understand and helps simplify future maintenance and updates.

Adding an APP Image

To add an image, either take a screenshot or use an existing image and save it as example.png or example.jgp in the specific APP folder in File Explorer.

The folder the image should be saved to for this given example.

important

The image must have a resolution of 320x240px. The name of the image must be "example". Otherwise the image will not be displayed.

Adding an APP Description

To add a description, create a file named description.txt containing the APP description and save it in the specific APP folder.The description supports HTML formatting, allowing elements such as bullet lists, line breaks, and text formatting to be displayed correctly.

The example below generates the description corresponding to the one shown in the figure above.

Example of description.txt.

The file must be named "description". Otherwise, the APP description will not be displayed.

note

Avoid adding unnecessary line breaks to the text file, as these will also appear in the displayed description.
