Noodle is written in the Uxntal programming language and is compiled with the uxn assembler, it features a handful of patterns, a pixel-perfect clean up brush, zoom functionalities and can export and import bit maps.

Re-naming a file
The default filename reads untitled.icn. To change it, click on the text. The text field will blink, allowing you to type a new file name.
Press ctrl + shift + r to erase filename, rather than using backspace.
To invert the image, press tab.
To save a file, click on the black star located on the bottom right of the window.
The star has two states: The black state indicates that the file was saved, the red state indicates that the file has unsaved changes.
To load an file, replace the active filename and write the name of the .chr file you wish to import, and click enter. To import the file click on the checkered square on the bottom right of the window.
If switching between projects, you can have multiple instances of the Uxn emulator open at various locations. Holding the alt key while clicking on the load-icon, will load the file as a 1bpp sprite sheet.
To load a blank file, click on the empty square icon on the bottom right of the window.
All changes will be lost, make sure to re-name your file.
Click on the teal band around the window to switch to focus view. This will make the menu disappear. Click again to bring the menu back.
To resize the canvas, pull on the black corner on the bottom right of the window. Adjusting the canvas size changes the number on top, next to the pattern menu. It's also possible to resize it by clicking alt + arrows.
Only resize the canvas at the start of a project, otherwise it will mess up your drawing.
It's possible to use the following tools to erase: brush tool, line tool, pen tool and rectangle tool. Select the tool you wish to use as an eraser, press escape key to toggle to erase mode, or click on a brush size in the top menu until it switches to a shape with a contour rather than one that is opaque.
It's also possible to erase using a pattern.
To erase the whole canvas press backspace.
A set of 8 patterns to draw with. To change pattern select numbers 1 - 8.
The default pattern is black. Select the brush, or rectangle tool first, and then a pattern.
A tool to draw thin single-pixel drawings on the canvas. The shortcut to select the pen tool is q.
This tool can only ever be 1 pixel. Erase by right-clicking.
A tool to draw brush-like strokes on the canvas. To increase or decrease brush size use the box brackets [ ]. The shortcut to select the brush tool is w. Erase by right-clicking.
To draw using a pattern, select a style from the pattern menu and toggle between each pattern using the numbers 1 - 8.
A tool to draw straight lines on the canvas. While the line is red it's possible to change its angle.
Lines will always be 1 pixel wide.
A tool to clean up lines. The shortcut to select the pen tool is r
This tool is useful to remove excess pixels when drawing sharp edges with the pen tool.
A tool to draw rectangles on a canvas. The rectangle tool shortcut is t.
To draw using a pattern, select a style from the right menu.
For a more detailed view of a drawing, select the zoom tool (shortcut is y), or press on the spacebar or shift. The magnifying glass has a little circle next to it when zoomed in.
Use the arrows to move around the canvas while zoomed in, and press the spacebar, or shift key to return to the normal view. If you toggle zoom again after having moved with the arrows, Noodle will remember this new position and zoom in on that exact point on the canvas. If you want to zoom in on another far-away part of the canvas, select the zoom tool and click on the area you wish to modify.
To create small animations there are basic tools to use. To add frames, click on the number on the right. This number counts up the number of frames in a project. The size of the canvas limits the number of frames, and Noodle restricts the allowable amount automatically. For more frames, resize the canvas to a smaller size.
The number on the left is your animation frames. On 0, draw the first frame, the another one the second, third etc. Clicking on the number, or pressing enter, will cycle through your frames.
To clear the animation, you must clear all layers individually.
The onion skin tool bears the appearance of an eye, when clicked open, it permits you to view a previous frame.
Exporting animations. You can export animations in Noodle to be used in other Uxn projects. Once your animation is complete, save the animation with the size of the canvas plus the number of frames as the name. The size of the canvas is written on the upper right of the screen, next to the pattern tools.
A project filename example would be: 2413x3.icn
Which means the canvas size is 24x13 and that the animation has 3 frames.
This number is in hexadecimal, which means that depending on the size of the canvas you may get letters. You don't have to do this, but if the animation is passed on to someone else, they will know how to size the frames.
