How to fill color in MediBang

I will explain the digital unique features and bucket tool.

With the bucket tool, you can paint a color in a blank area around the line.

“Bucket Tool” is located in the toolbar on the left side of the main window ((1) tool).

First of all, please download and open the sample for this tutorial.

Next, click “Bucket Tool (1)” button and switch to “Bucket Tool”.
“Toolbar” for “bucket tool” is displayed at the top of the main window.

Let’s explain each function of the toolbar.

About Reference

It is the object to reference when deciding the area to be painted with a bucket. You can select either “Layer” or “Canvas”.

If you set the reference to “Layer”, fill the area surrounded by lines against the active layer. If you set the reference to “Canvas”, fill the part surrounded by the line against the canvas.

let’s try it

Please select the “not drawn” layer of the sample, set the reference to “Canvas” and click inside the red circle. The inside of the red circle is painted with the foreground color of the brush.

Next, please undo once and cancel the fill.

Next time, select the “not drawn” layer, set the reference to “Layer” and click in the red circle. The entire canvas is painted.

In this way, you can adjust the area to be filled with a bucket by switching the “Reference”.

About Tolerance value

If you set the “Tolerance” value, you can apply color in a bucket at a time even in slightly different colors.

let’s try it

Let’s paint the inside of the yellow-green circle by selecting the “not drawn” layer of the sample, making the reference “Canvas” and changing the tolerance.
(Every time you fill, please undo, erase the yellow green circle with a layer clear or eraser and fill it in new.)

When the allowable value is 1, the filling of the bucket stops when the color changes even a little, so if you paint a line with blur like an airbrush, a large white area will remain around the line However, if you set the allowable value appropriately, you can paint cleanly with lines like airbrush.

About anti-aliasing

When checked, anti-aliasing of filled border becomes effective.

let’s try it

Switch anti-aliasing checks and fill in the “inner circle” of the sample “black double circle” to check the difference. Let’s enlarge the canvas display when it is difficult to understand the difference as it is.

About extension

If line drawing is anti-aliased, there may be a gap between line drawing and bucket painting. You can use “Expansion” to fill that gap.

let’s try it

Let’s change the value of the extension and fill in the “outer circle” of the sample “black double circle” to see the difference.

About Close Gap

If you use the “Close Gap” function, you can paint even a slightly interrupted line drawing without sticking out. If you check “Close Gap” you will be able to choose level in 5 steps. “Close Gap” will be invalid if unchecked.

let’s try it

Let’s paint in the blue circle of the sample with a bucket while changing the level of the gap closure.

When the level is 1 or 2, it will protrude out of the circle, but if you increase the level above 3, you will be able to fill in only the circle.

In this lesson, we will introduce a function that makes it easier to use the bucket tool, which can color blank spaces in one go.

Mastering this function will save you time, so we hope you are going to find this lesson useful!

• Use the enlargement function
• Using the gap closing function
• Select the area you want to paint by selecting layer or canvas

Use the enlargement function

First of all, to avoid painting the whites of the eyes, we have painted around the eyes with the pen tool before doing anything else.
We have also used a dark color to make the difference in color easy to see.

If you paint with the bucket tool right now, you will get a gap between the line and the color.

The enlargement function is what you need in such cases.

When you select the bucket tool, it will be displayed at the top of the screen.

Increase the numerical value here to be able to paint wider than the range that the paint is normally applied.

Here, we painted with the value changed to 2. This enabled us to paint the area fully without leaving a gap between the line and the color.

Using the gap closing function

If there is a gap between the lines, painting with the bucket tool may cause the colors to bleed in the way you can see in this image.

The gap closing function is useful in this kind of situation.
As the name suggests, this function makes slight gaps undetectable.

There were small gaps in the girl’s fringe and gaps between the hair and the lines of the skin, but using this function stopped the colors bleeding out from the gaps.

Basically, we recommend you use the above two functions together when painting with the bucket tool!

Select the area you want to paint by selecting layer or canvas

When painting with the bucket tool, you can choose whether to paint on a canvas or on a layer.

You can switch between these using “reference.”

In canvas mode in reference, you paint the blank area just as you see it on the screen.
Here, we want to paint the eyelashes, but there is interference from other lines, so we can’t paint them in one go.

Selecting the layer mode enables you to paint blank areas of the image that is on the selected layer only, ignoring all lines on other layers.

In addition, if you set a larger numerical value for “tolerance,” paint will be applied in areas with a slightly different color.
This function is convenient when you import analog line drawings using the camera or want to paint line drawings that have noise.

So what do you think?

Changing the range in which the color can be applied in such a way makes the bucket tool much easier to use. This is definitely something you’ll want to master!
