This blog post quotes an excellent video I got shared by a friend, which thoroughly debunks why performance improvements should not be allowed in production applications.

This blog post explains the rationale behind the new G’MIC-Qt plugin we ship as part of Krita 5, and how to build and package it.

It has also been published as the new README.packagers.md in the Krita repo.

Hey all!

It’s been quite a while since my last post. Exams for my teaching certification have not gone as expected – had to pull out after being flattened in quite a critical one…

Buuuut! I am glad to announce that the SeExpr documentation is now available in the Krita manual!

Hey all!

I’m glad to announce that my GSoC 2020 project has been merged!

You should be able to use Disney’s SeExpr for fun and profit as soon as the next nightly.

The next objective is getting the docs in shape – see this merge request for more information; and, of course, we still need your help for a good batch of scripts to bundle with!

Thank you all for helping out!

Someone on #krita, can’t remember their exact nick, asked if it was possible to run Krita on ARM-based computers, specifically the Raspberry Pi 3B+. AFAIK, no one has tried to do so, so I will tell you: yes, it is possible! (Although it will run as slow as a turtle!) This work took me the whole weekend, but it was an excellent experience as well as a wonderful way to test our infrastructure.

A key warning before moving on: DO NOT TRY THIS ON YOUR PI. It will be unbearably slow 😄 I built mine with a Ryzen 7 with 12 threads and it still took me two 12-hour shifts!

This post covers three steps: setting up the build environment, compiling the dependencies and Krita itself, and finally packaging the AppImages themselves. As per the official instructions, we’ll target Ubuntu 16.04 ARM. I chose the armhf port to match the Raspberry Pi’s default distro, Raspbian. I also tested aarch64 – see the last section for the necessary changes.

I’m glad to announce the third alpha of my GSoC 2020 project. For anyone not in the loop, I’m working on integrating Disney’s SeExpr expression language as a new type of Fill Layer.

I’ve already announced this on Krita Artists, but I haven’t had time to write more fully about it, so…

I’m glad to announce the first alpha of my GSoC 2020 project. For anyone not in the loop, I’m working on integrating Disney’s SeExpr expression language as a new type of Fill Layer.

Hey all! Just a quick heads up on my GSoC project.

Hey all! This is my first report of the project’s Coding Period.

The project’s objectives for this week are:

• define the new generator
• build SeExpr
• and try calling it from within Krita

I had also promised in the previous post to:

• dissect SeExpr
• write up a list of the supported libraries in each OS.

Good morning everyone!

I’m checking in today to let you know what I did in my GSoC project these past weeks. This Community Bonding period was really wonderful; although I’ve been more or less involved with the project since 2016, I’ve acquainted myself with the efforts of each of the members, and so far it’s been a wonderful experience.

During these past weeks, I’ve been preparing for the coding period by talking with Boudewijn and Wolthera about the particulars of Krita’s file format and build system. The objectives for the past two meetings were:

• speccing the new layer
• integrating SeExpr into Krita’s dependency build system
• document the process

This post summarizes my efforts on each of these bits. I apologise for the late post; but this week I got to attend (virtually) my first Eurographics and LGM sessions, and with the homework load, it’s been some wild days.

Without further ado, let’s see how deep this rabbit hole goes.

Good morning everyone!

For this Community Bonding period post, I want to write about what this project is about. I’ve gotten some questions about its scope and how it will benefit the Krita community, so a full writeup may help clarify these bits. As I’m a Computer Graphics student, this post may be biased towards the math-y bits, but I hope it’s still clear.

Let’s get started!

Hi again, everyone! This is the final post for this series, in which I’ll show you how to set Krita up in Visual Studio Code. For this post, we’ll cover the Windows operating system. I’ll show you how to take advantage of the same build scripts maintainers use for building the Windows releases.

Hi again! This is the second installment of this series. Today’s post will cover how to set Krita up in Visual Studio Code, under macOS. I’ll show you how to take advantage of the same build scripts Iván and Boudewijn use for building the Mac releases.

Hi all! As part of our Community Bonding period, I wanted to share my experience setting up a development environment for Krita. We already have David Revoy’s post and the official, updated documentation. However, they only cover the setup process in Linux.

I’ll show you how to set Krita up in Visual Studio Code, under the three major desktop OSes: Linux, Windows, and macOS. For the latter two, I’ll show you how to use the same build scripts maintainers use for building the releases. We’ll take advantage of Visual Studio Code’s Tasks, so you do the hard work once, and then you’ll be able to compile dependencies AND run Krita in a few keystrokes!

Today’s post will tell you how to set Visual Studio Code up in Linux.

Hi everyone! It’s been so long since I started this site, back in July 2017. It’s been mostly to showcase my open source work and have a place for potential business contacts, and I’ve never ever blogged a bit because long prose is kind of difficult for me. (Also, I’m very fearful of our dear internet trolls.)
