97. Bucket tool details

The Bucket setting in ibis Paint has the most functions in its kind among all the painting apps that are available. Since it packs so many functions, it may be difficult to learn all of them. Also, if your aren't careful, you might end up coloring the entire canvas without knowing, or filling only a small portion of your image. However, since you can always use the undo function to revert one step, you can try its various functions without worry. Although we will be explaining the Bucket settings here, you can also read the Magic Wand settings if you need to, since the two share most functions.

Bucket function allows you to fill parts that are similar in color with the color of the starting point. The most used is coating under the line drawing.

If the lines of the line drawing are closed off, the fill stays inside of it. If there is an opening, the color may spread to the entire canvas. If it has, do not panic; use the undo function (reverts 1 step) to return to the original state.

Next, we'll explain the Bucket setting window.After selecting ① the Bucket tool, tap on ② the % button to open the Bucket setting.

① Bucket Easy Settings ... Since it is quite difficult to adjust all the settings for the Bucket function, the Bucket function by default has easy setting enabled to get you started quickly. Even if you change the settings after turning easy setting off, once you leave for My Gallery, easy setting will be turned on again. Once you feel like you have a good grasp of the Bucket functions and settings, you can press the gear icon in the Tool Selection window, and turn on "Save Bucket Settings". If you do this, the Bucket settings will remain as they were changed, even after leaving for My Gallery. Here, in order to adjust other settings, please turn easy setting off.
② Strength ... It lets you set how much similar in color as the starting color the Bucket tool should cover.

The strength of the Bucket settings is being able to set how similar in color as the starting color the Bucket tool will cover (Bucket tool will cover up to a certain difference in color as the starting color). If there is an airbrushed gradation in the image, you can set the strength setting to 0%, and the Bucket tool will stop as soon as it encounters a color that is even slightly different from the original color. If you set it to 5%, it will cover a little more area, and 10% will cover even farther. If you set the strength too high, it may leak and cover the entire canvas.

If the strength is set too high, the color will end up leaking through fine and thin edges like this. In this case, try setting the strength to 0%.

Shown above is a picture of a giraffe loaded through image importing, which is filled with 0% strength. If the strength is set to 0%, the color will not be able to spread much. Also the squared and pixellated parts are called JPEG block noise (normally, pictures are saved as JPEG files). Since JPEG files are made up with extremely small squares, if you fill it with 0% strength, you can see what they consist of. In such cases, it's better to raise the strength value.

Expansion ... Expansion is a setting that lets you either expand or shrink the area (after specifying the area) for coloring with a different color as the initial point. The default value is 1.5px.

Above is a comparison of two illustrations drawn with a G pen (soft), filled with 0 px, and 1.5 px expansion, respectively. Since the line drawing has anti-aliasing (translucent) on the edges, the white is still visible with 0 px expansion. By increasing the expansion value to 1.5 px, you can reduce the white parts visible on the edges.

If you want to fill the speech bubbles in manga, you can shrink it by negative expansion value.

① Boundary ... Boundary is a setting that allows you to decide whether you will use color (RGB) or opacity alone to let the program decide how much it will fill the canvas depending on the closeness of the color to the starting color. When the reference layer (to be described later) is the canvas, the canvas is entirely opaque when the background color is white, so if you select opacity as the boundary, the entire canvas will become colored. If the reference layer is a specified layer or a current layer, it may be better to set the boundary to opacity.
② Reference Layer ... Reference layer can be selected from current layer, specific layer, and canvas. The default setting is canvas. Reference here refers to the area of the image the program references when learning how much the Bucket tool should cover. When you select the canvas, you can decide the range by referencing the picture (as shown) that combines all the layers. When you select a specific layer and specify a layer beneath it with the layer selection list, it references that layer and determines the area to be painted. When you select the current layer, the program decides the area to be painted by referencing the current layer. By using the specific layer, you can also have the line drawing and the color filling in different layers: you can draw a line drawing on layer 2, and fill it with layer 1 as the current layer.

After finishing the line drawing and coloring, add a layer just above the bottom of the work's layers (which contains the background material). You can select that layer as the current layer, and set the expansion to 50 px in the Bucket setting, and color with white to draw the outline. Specifically, hide the layer with the background materials, and make the layer background transparent. Afterwards, in the Bucket settings, set expansion to 20 px, boundary to opacity, and reference to the canvas. Then, color with white, and unhide the layer with the background materials to create something in the figure shown above.

If there are gaps in the line drawing, it is better to fill them in using a pen with the same color as the fill color. Line drawing of hair, for example, likely has gaps.

The line drawing becomes layer 2. If you want to turn layer 1 brown, fill in the gaps in layer 1 with a brown pen.

In the Bucket settings, set the border to color, 0% strength, 1.5 px expansion, and set the reference layer as the canvas, and proceed to fill. When you do so, you will be able to color inside the hair area, as shown above.
Although it is hard to comprehend all of the various features of the Bucket function, you can keep trying different things out by reverting to the previous step, using the undo function.
