Storyboard Docker For Krita

Project Overview

A storyboard is a graphic organizer that consists of illustrations and comments displayed in sequence for the purpose of pre-visualizing and planning of motion picture and animation. The project was to implement a docker in Krita that would use the existing animation API in Krita to facilitate storyboarding. Qt's MVC classes are used for storing and displaying the storyboard.

Project Goals

The requirements of the project can be broken down into the following goals:

• Implementing the basic MVC classes for the docker.
• Integrating relevant parts of Krita, namely the timeline docker and canvas, with the storyboard docker.
• Implementing functionalities to export storyboard as PDF and SVG.
• User documentation.

The mockups prepared for the project:

Relevant Code and Technical Pre-requisites

MVC classes

Talk about MVC classes, comment and storyboard.

Krita's Anamtion API

Talk about Keyframe and keyframe channels. Talk about AnimationInterface Talk about the syncing and addition of keyframes.

Work Report

Implementing the MVC classes for the docker

Week -1

I started a few weeks early, to cover up for any unprecedented events due to ongoing COVID-19 crisis. This week I added the storyboard docker to Krita's plugin system and implemented the tool-buttons at the top of the docker and the menu related to those buttons. I implemented the CommentModel class to manage the comment tool-button's menu. The members of this menu would be part of the storyboard items that would be part of the storyboard model. I also started implemented the StoryboardModel class. (Commits :1)

Week 0

I implemented the delegate class for the CommentModel. I also added a visibility property to members of the CommentModel. This property is shown as an eye icon which can be toggled by clicking. I also implemented the StoryboardItem class that makes up the data of the StoryboardModel and implemented functions in StoryboardModel to manage that data. (Commits : 2, 6)

Also I implemented unit-tests for the CommentModel, StoryboardModel and the interactions between those classes.(Commits: 3, 4, 5)

Week 9 and 10

I implemented the saving and loading of storyboards. For this I stored a QVector of Comment and a StoryboardItemList in KisDocument. This version of data is kept in sync with the version that is inside CommentModel and StoryboardModel.(Commits: 57 58 59 62)

I also added unit-tests for saving and loading of storyboards. These tests were added in kis_kra_saver_test.cpp. (Commit: 56)

I worked on the Export dialog GUI and implemented some of its functions.(Commits: 63 64)

Other than that I added a patch from Eoin O'Neil, fixed some changes and merged my branch with master. (Commits : 54 55 60 61 65 66)

Introduction

Storyboard docker

The storyboard docker aims to facilitate storyboarding in Krita. It allows multiple images and associated text to be organized in the form of a storyboard. The arrangement can be tweaked using the mode and view options. Also different field's visibility can be toggled. The storyboard can be rendered as pdf or svg.
