Learn the basic screen composition
It is a screen configuration in a state that does not customize anything by activating MediBang Paint.

If you want to return the window to the initial state, such as erasing the window by mistake, you can return to this state at any time by “Window” → “Initialize” of the menu.
Next, we will explain each window.
(1)Color window
It is a window for making brush color.

By moving this red frame you can also move the area displayed in the main window.

If you register the brush size you often use in the “Brush size” window, it is convenient to change the brush size easily.

When you right click on the brush size window, the “Edit Brush Size” menu is displayed, clicking it will display the brush size edit window.

In the “Edit Brush Size” window, you can register your favorite brush size with a line break separator. If you want to return to the initial state, please press “Initialize Brush Size” button.
Let’s use Undo / Redo
When doing the wrong operation, it is “Undo” that can cancel the previous operation, and “Redo” to cancel the previous “Undo”.

Most operations can be canceled with Undo, so please use it.
Tips
You can Undo by holding down the Ctrl key and pressing the Z key on the keyboard. (In case of Mac version, press Command key while pressing Z key)
We recommend you to keep in mind that this is a common operation not only for MediBang paint but also for most Windows / Mac applications.
POINT
MediBang Paint has no fixed upper limit on the number of Undo and you can restore your work as far as your PC’s memory permits. When memory for Undo runs short, it disappears from the oldest Undo information.
Learn the various rotation methods
MediBang Paint has three kinds of rotation and left / right reversal. Let’s learn the difference.

Based on this picture, I will explain how each rotation works.
Rotate and flip only the display
It can be executed by “View” → “Rotate Left” / “Flip” / “Rotate Right” of the menu. (It is the same even if you operate in the “Navigator” window.)

Only the display of the canvas flips horizontally and the display of the navigator and layer remains intact.
In this operation, since only the display is rotated and reversed, the data saved in the canvas is saved in the original state.
Rotate and flip the canvas
It can be executed by “Edit” → “Rotate Left” / “Flip Horizontally” / “Rotate Right” of the menu.
The entire canvas (all layers) will rotate and flip.

In this operation, not only the display but also the saved data of the canvas are saved in a rotated state.
Rotate and flip layers
It can be executed by the menu in “Layer” → “Rotate” of the menu.
Only the selected layer rotates / flips.

In this operation, not only the display but also the saved data of the canvas are saved in a rotated state.
Let’s use a “Snap tool”
A “Snap tool” is displayed at the top of the window when selecting a tool that can use a “Snap tool” such as a brush tool.

- (a)
- Set the ruler to OFF (not shown). The state of the ruler is retained.
- (b)
- It is a ruler that can draw parallel lines at any angle. The angle of the ruler can be changed by pressing “reset button (i)”. You can change the angle in units of 15 ° if you press “Ctrl (Command on Mac)” to change the angle.
- (c)
- It is a ruler that can draw vertical and horizontal lines.
- (d)
- It is a vanishing point ruler. First, select any four points to determine the vanishing point. To reset the vanishing point, please press “reset button (i)”.
- (e)
- It is a ruler that draws a concentration line. If you want to change the center of the concentration line, please press “Reset button (i)”.
- (f)
- It is a ruler that draws concentric circles. If you want to change the center of the concentric circle, please press “reset button (i)”.
- (g)
- It is a curve ruler. If you click along the point you want to draw a curve, you can create a ruler that matches the curve. Double click to confirm the ruler. If you want to change the shape of the ruler, please press “reset button (i)”.
- (h)
- It is a ruler that draws an ellipse. When you drag the canvas, an ellipse ruler is made.
- (i)
- Reset the state of the ruler.
Save Snap
The snap can be saved. The snap data is saved in mdp file, and it can store up to 10 pieces per mdp file.
To save snap, use “Snap” → “Save Snap” in the menu.
You can call up the saved snap from the “Snap” menu.
(※There is no function to change or delete the name of the ruler saved at Ver 20.1.)
Left toolbar
I will explain the toolbar on the left side of the main window.

(a)Move tool
Using the “Move tool” (the button in (a)) you can freely move the picture drawn on the selected layer.
Movement is done by dragging on the canvas.
Tips
You can move it horizontally and vertically by holding down the Shift key and using “Move Tool”.
(b)Fill tool
Using “Fill tool” (button (b)), you can easily fill in rectangular, elliptical, polygonal shape.
When you select the Fill tool, “Special tool bar” of “Fill tool” is displayed at the top of the main window.

- (A)
- Select the shape of the fill.
- (B)
- Set whether antialiasing is applied when filling.
- (C)
- Rectangle / Polygon Set whether to round the fill corner. In case of rounding, also set the degree.

- When it is a rectangle / ellipse, it specifies whether to fill a diagonal line and fill it from the center.
When checking the selection from the center on the right (when drawing like a red arrow)
- (E)
- When it is a rectangle / ellipse, it specifies whether the aspect ratio is 1 and it fills. If checked, concentric circles are filled with squares.
- (F)
- Specify the opacity of the fill.
(c)Gradation tool
Using “Gradation Tool” (button (c)) makes it easy to create gradations.
When “Gradation tool” is selected, “Special tool bar” is displayed at the top of the main window.

- (A)
- Select the shape of the gradation from “linear” or “circle”.
- (B)
- Select the gradation type from “Foreground to Background” or “Foreground”.
The left is “foreground to background” right is “foreground”. If you select the foreground, it will gradate from the foreground to the transparent color.
The width and direction of the gradation are determined by the stroke in the canvas.

(d)Shape brush tool
Using the “Shape Brush Tool” (button (d)), you can easily write shapes.
Unlike the Fill Tool, you can draw shapes with the current brush.
