dotto's Issues

add android support to the coming soon feature list

QUESTION: How can I tell where the pixel is going to be placed?

How do I know where the pixel will be placed if the brush indicator is two pixels tall/wide?

The built AppImages from GitHub actions tab is broken on Fedora 38

Describe the bug
It doesn't launch. It's probably related to #44.

To Reproduce

1. Get a system with Fedora 37 on it.
2. Make the AppImage executable.
3. Try to launch it.

Suggested Fix
Maybe bundle node with Dotto?

Desktop (please complete the following information):

• OS: Fedora 37

Windows lib failure

Couldn't Launch on Windows Because Of Missing Library

On Windows 10 I Cannot Launch The Latest GitHub Actions Build Because libjxl was not found, basically the libjxl.dll isn't included in the build.

Flatpak support

Linux has a packaging format called Flatpak so when this drops it would be great if it supported it

Conflicting Dependencies on Fedora 37

Describe the bug
When I try to install the dependencies with this command:

$ sudo dnf install g++ make SDL2-devel SDL2_image-devel v8-devel lcms2-devel freetype-devel zenity libXi-devel

I get this error:

Gui not loading correctly

Compiled the git repository on Arch Linux,
while starting I get following error:

Could not create St10shared_ptrI11PropertySetE out of Dn

Any clue how to fix this?

Dotto! - What? Who? Why? When?

What

LibreSprite Dotto! is a clean-room, modern, flexible rewrite of LibreSprite. Since it does not reuse code, it is more of a spiritual successor than a new version, hence the new repository.

---

Who

The core is currently being written by myself, though @Zughy and @maujin111 have been closely involved since before day 1.
Due to the scripting system being tightly integrated, the JavaScript and Lua programmers of the community will soon be able to get involved as well.

---

Why

First, some context. LibreSprite was born half a decade ago, as a fork of Aseprite. Aseprite, in turn, was born shortly after the invention of the transistor. Despite numerous rewrites and refactors, the codebase showed serious signs of age. Notably, it was based on a buggy, custom, old version of Allegro for rendering and often did not follow standard C++11 coding practices.

After the fork, Aseprite went on getting refactored/maintained/improved, while LibreSprite mostly just sat there, gathering digital dust.

Recently, an effort was made to make the fork usable. An SDL2 backend was added as an alternative for Allegro and several bugs were patched. During this process, one thing became painfully obvious to the maintainers: adding new features without breaking things is going to be really, really hard.

As an example, we often get requests for new tools. Ideally, LibreSprite would be flexible enough to allow users to add their own tools by making simple scripts. Unfortunately, there is a lot of hardcoding in the existing set of tools. They're even hardcoded to skins as old skins have no way of displaying icons for tools that came later. Our community is fond of custom skins and breaking existing skins every time we want to add a new tool isn't what we want.

Looking at the current state of LibreSprite, we came to the conclusion that getting it to where we are comfortable adding new features would take just as long as simply starting again. This was not at all a decision taken lightly. Throwing away decades of work and doing it again is not going to be easy. So Dotto! was born initially as a prototype branch, where we tested the waters to see if it was really something we wanted to do. Now we know: it is.

---

When

It's opensource, so: it'll be ready when it's ready. As of this writing, Dotto is 3 weeks old. Compared to the decades of work that had already been put into LibreSprite by the original author, there is still a long road to go. On the other hand, progress is really fast. Keep an eye out for updates here and on Discord or Matrix, if you blink you'll miss 7 commits.

Wayland Support

It's a nice to have, but not necessary

Could not load language [en_US]

Im on gentoo trying to run dotto and it give me the error Could not load language [en_US] and doesn't run

Undo and redo support

I tried Ctrl+z and it didn't seem to work

Control+A shortcut in new picture area

It would be nice to be able to use standard shortcuts like these

Rectangle selection tool

Bug - Linux App Image, possibly every version.

When color wheel is open, say by accident, then you click the brush tool, Dotto crashes.

Make cannot find Lua

The package I installed for Lua was Lua5.3, make cannot find the package for Lua because I could not use the default package name.

Package lua was not found in the pkg-config search path.
Perhaps you should add the directory containing lua.pc' to the PKG_CONFIG_PATH environment variable No package 'lua' found g++ -Og -g -D_DEBUG -Ilibs -Ilibs/tinyxml2 -Ilibs/duktape -Ilibs/tinyfiledialogs -Isrc -MMD -MP -I/usr/include/SDL2 -D_REENTRANT -I/usr/include/freetype2 -I/usr/include/libpng16 -DSCRIPT_ENGINE_LUA --std=c++17 -c src/cmd/Paint.cpp -o build/src/cmd/Paint.cpp.o Package lua was not found in the pkg-config search path.

Confused on how to compile on Mac

im a bit confused on what to do when compiling Dotto on Mac

Is the compilation process supposed to take a few minutes?

I haven't learned too much about C++ after the basics. So should compiling a project like this take a long time?
