[1] What is [Closed area fill]?

Closed area fill is an option to configure how the area surrounded by the tool will be filled.

The sub tools Refer only to editing layer or Refer other layers can fill in areas with the same color, when they are surrounded by outlines.

 

These areas that are surrounded by a line drawing is referred to as the Closed Area. This refers to areas (seen here in red) that can be filled by clicking inside of them with the Fill tool.

However, in actuality, closed areas often have very complex shape, and therefore it is more difficult to fill in such areas just clicking on them.

The Closed area fill is an option that can fill in these intricate closed areas effectively.

 

The two sub tools that utilize this option are the Enclose and fill tool and the Leftover pen tool.

 

[2] Sub Tool [Enclose and fill]

Enclose and fill is a sub tool that can fill in all the areas that are enclosed within a selection.

 

 

 

■1. How to enclose an area

 

Among the four circles below, the one in the lower right will not be filled because the range of the Enclose and fill does not include the lower right line to satisfy the requirements for this part of closing an area.

(Depending on the settings of the Target color, areas that are part of the selected range might be filled in. For details on the Target color, see “[4] Target color".

Firmly enclose the closed area you wish to fill in.

On the other hand, for closed areas you do not want to fill in, it will not be filled in when just enclosing them partially, so you do not have to avoid completely.

 

 

 

■2. Area scaling

 

Enclose and fill is a sub tool that can fill in all narrow closed areas that are enclosed in the selection.

In the initial settings, Area scaling for Scaling mode is set to To darkest pixel in order to not have color overflow from the closed areas in case of filling in highly concentrated locations.

In case color overflows to the nearby areas, please check these settings.

 

 

 

■3.Tolerance

 

There can be seemingly un-colored areas that are actually not completely transparent in areas that are not filled in an anti-aliased drawing.

 

In such cases, if there are any transparent areas, no matter how small, they can be painted by using the Area scaling.

For example, in very narrow parts such as the hair, there may be parts that consists of only such semi-transparent lines.

If there are no actual transparent parts (meaning that there is no object to fill) like this, it can not be filled in with the Area Scaling.

In this case, you can adjust this by changing the value of the Tolerance.

In the following case, changing the **Tolerance* to 80 has filled in the area neatly.

 

<The tolerance of which color?>

The tolerance is the difference between the color to be filled and the color that makes up the closed area.

In this case, since the Target color is Only transparent, the transparency margin will recognize the area to fill.

The color with thin anti-aliasing will be filled in with the transparency margin, since the color’s opacity has become low.

For details on the Target color, see “[4] Target color".

 

[3] Sub Tool [Leftover pen]

Leftover pen is a sub tool that can fill in all the area that are traced with it.

Since it can be used similar to the pen tool, it can work with more complicated parts than what the Enclose and fill tool could.

 

 

 

■1. How to enclose an area

 

The way in which the area is selected is the only difference between the Leftover pen tool and the Enclose and fill tool.

When tracing with the Leftover pen function, that area is shown in green. Only the enclosed areas that exists within it will be filled.

Similar to Enclose and fill, parts that are not enclosed within the green selection would not be filled.

(Depending on the settings of the Target color, areas that are part of the selected range might be filled in. For details on the Target color, see “[4] Target color”.)

 

 

 

■2. Size

 

Since Leftover pen can have its setting modified similar to the pen tool, it is capable of filling very intricate areas.

 

 

 

■3. Area scaling and Tolerance

 

Since Leftover pen is configured to fill in narrower areas rather than Enclose and fill, Area scaling is set to off and Tolerance is set to a larger value in its initial setting, to prevent overflowing to other areas.

 

[4] Target color

With Refer only to editing layer and Refer other layers, the same color clicked in the tool will become the target to fill.

Sub tools that use Closed area fill, such as the Enclose and fill and the Leftover pen, will select the color or the target for filling that composes the closed area at the Target color.

Depending on the settings, it can be used for color changes for not only the transparent unfilled areas, but also for black and white unfilled area.

Enclosed with the pink line and filled with red, this will explain the differences for the filled areas depending on the Target color.

To make it easier to understand the layer to fill is placed above the line drawing.

For figures that are drawn on the Reference layer, anti-aliasing is turned off for all figures except ④.

 

 

 

■1.Target all colors

 

Within the enclosed area, the parts that are closed areas within the selection would be filled no matter what color they are. In this case, the area to be filled includes internal transparency and colors alike.

For figures such as ⑤ and ⑦ that do not include full transparency or another color, they are colored completely, including the somewhat transparent parts that they have.

 

[POINT: Be aware of drawings with anti-aliasing]

Drawings with anti-aliasing will be filled in when enclosing the entire drawing. However, if only a part is in range, only those parts will be filled. In case of plains, only the edges will be filled.

When enclosing only a part of an anti-aliased drawing, there will be situations where semi-transparent, transparent and black (color) etc. are mixed in the range, and thus create many small closed areas.

If you enclose the whole drawing, all of the drawing will be filled, as all of it is within the enclosed area.

 

[POINT: Be aware of filling opaque areas]

Opaque areas, depending on the Tolerance settings, may be evaluated as transparent and will not generate closed areas, and thus remain unfilled.

Even if anti-aliased drawing is part of a certain range of selection, the same phenomenon might occur and you can avoid it being partly filled.

 

 

 

■2. Transparency only

 

Within all of the enclosed area, only the transparent areas within an enclosed area will be filled. This setting is set to the initial setting of Enclose and fill and Leftover pen.

 

 

 

■3. Area surrounded by transparent

 

Within the enclosed area, closed areas surrounded by transparency will be filled in regardless of the color of the area.

Unlike Target all colors, if there is a transparent area inside as it is in figure ③, ④, ⑨ and ⑩, the transparency within a figure will not be filled in as it is part of the surrounding transparency.

 

[POINT: Be aware of thin drawings]

If you enclose only a part of a thin line, the behavior of the filling will differ depending on the setting for the Close gap function.

In case Close gap is activated, the closed area may be generated within the surrounding transparent area and thus painted in depending on the line width of the target and its value.

In case Close gap is disabled, the closed area will not be generated, and thus not be filled in.

 

 

 

■4. Only black

 

Within the enclosed area, only the black areas that are closed in completely will be filled in.

 

[POINT: Be aware of drawings with anti-aliasing]

Like in ④, anti-aliased drawings with thin semi-transparency will not be filled with this setting, and therefore resulting in unfilled areas.

If the lines as shown on the left side, there will be unfilled areas.

In case the area to fill is wider, as shown on the right, it may seem like it was filled in completely, but gray portions at the edges of the drawing still exist, which means there are unfilled areas there.

 

The Only black function can be used when trying to remove dust from a scanned draft by setting the drawing color to Transparent or White.

 

 

 

■5. Area surrounded by black

 

Within the enclosed area, the closed areas surrounded by black will be filled regardless of their color.

 

[POINT: Be aware of drawings with anti-aliasing]

Drawing with anti-aliasing, like in ④ may not lead complete fills for semi-transparent area. As shown within the circle, there will be closed-in areas surrounded in black that are not properly colored.

In such a case, you can adjust the Tolerance so that thin, semi-transparent areas will be recognized as black and thus establish the closed area. Configure Area scaling simultaneously and set Scaling mode to To darkest pixel.

 

• Tolerance 10/Area scaling Off

This will not recognize a closed area surrounded by black, and therefore will not fill in the area.

• Tolerance 30/Area scaling Off

The gray area will be recognized as black as well and the closed area will be filled.

• Tolerance 80/Area scaling Off

At this point the range for the margin is too large and the thin gray area will be excluded from becoming part of the closed area, resulting in an unfilled area.

Using To darkest pixel from the Area scaling will increase the area to fill while also preventing any overflow.

 

• Tolerance 80/Area scaling 10 → To darkest pixel

 

 

 

■6. Only white and transparent

 

Within the enclosed area, only the white and transparent closed areas are filled.

Like for ⑨, a drawing that consisted of white or transparent areas, are composed only of filling targets, so they do not become closed areas and can not be filled.

 

 

 

■7. Area surrounded by white and transparency

 

Within the enclosed area, parts that are closed areas within the selection would be filled no matter what color they are.

 

 

 

■8. Treat pale transparent as transparent

 

Within the enclosed area, the parts that are closed areas within the selection would be filled no matter what color they are. In that case, the areas to be filled include transparency and the colors within them.

Treat semi-transparent as transparent ” is a newly added setting to Target color. Actions other than filling thin semi-transparent areas will be considered the same as the Target all colors**.

 

[POINT: Be aware of drawings with anti-aliasing]

Similar to **Target all colors”, drawing with anti-aliasing effects, will fill everything if the entire drawing is enclosed, but if only partial areas are enclosed, only the areas within the selection will be filled.

In case of plains, only the edges will be filled.

Treat semi-transparent as transparent allows to distinguish semi-transparent areas as transparent and is able to fill in more cleanly as compared to areas that were not filled with the Target all colors function.

However, it might also fill semi-transparency on the outside, which would make the surrounding area a different color and it may look as if there as overflow.

In case you wish to fill the inside of a line cleanly, select other setting and combine/use To darkest pixel from the Area scaling function.

 

 

 

■9. Other than transparent and inner transparency

 

Within the enclosed area, this fills in the non transparent color areas and inner transparent areas that are enclosed.

While basic function is same as that of Target all colors, processing slightly changes when anti-aliased drawing enters the range.

With Target all colors, there are cases where areas that are part of a selection are filled due to the value of the Tolerance.

When using All enclosed areas except transparency, areas are not filled, regardless of the value for the Tolerance.

 

 

 

■10. All enclosed areas including transparency

 

Within the enclosed area, the fill in only applied to areas that have color (including transparency). In this case, the areas to fill include transparent areas and the colors within them.

Within the enclosed area, even partial areas that are part of the selection will be colored in, regardless of their color or anti-aliasing effect.

Transparent areas will only be filled in, in cases where closed areas are larger than the transparent areas like in ⑩.

 

[5] Creating an original sub tool

Closed area fill not only fills unfiled areas, but it is also able to fill in several distant closed areas at once.

However, Enclose and fill and Leftover pen have the same operation as the Lasso tool and the Pen tool, and therefore they are not perfect for filling large areas.

If you wish to enclose areas in other ways, try making a new sub tool.

 

① Select Create custom sub tool from the menu that shows after clicking the menu button from the Sub Tool palette.

 

② Select Input process and tap OK after selecting Closed area fill for the Output process from the Create custom sub tool dialog box. Here, the Figure tool has been selected.

 

③ Since the created sub tool will appear in the Sub Tool palette, configure each item from the Tool Property palette and Sub Tool Detail palette.

 

④ Once the configuration is completed, right click the sub tool created from the Sub Tool palette and change the setting back to default from Save as default.

You can paint distant closed areas by enclosing them in a rectangle now.

Sub Tools created by using other Input process functions will be enclosed as follows.

 

• Input process > Continuous curve

 

• Input process > Unit curve
