Step 3: Area Selection

Selection icon group

Using selections, you can copy, fill or draw in the selected area.
Here, I would like to introduce some technique using selections.
First let's start from the basic usage.

1.Various Selection Types

	Rectangle
	Drag and make a rectangular area of your choice. You can change the size of the selected area by dragging the tiny squares on the lines and at the corners. You can move the area by dragging the inside area. If you first drag with the [SHIFT] key down to make the selection, you can make a complete square.
	Line
	Drag and make a straight line. You can move the line by dragging the line. This selection is for drawing a straight line. You cannot fill in the area. (There is no area to fill, to begin with...)
	Circle
	Drag and make a circle area. Drag the tiny squares at the corners of the lectangle that fits outside the circle, and you can change the size of the circle. Dragging with [SHIFT] key down makes a complete circle.
	Polygon
	Click, click, click, and you can make a polygonally selected area. Right clicking completes the selection. Drag the tiny squares at the corners and you can change the shape and size, and drag the inside of the selected area, and you can move the area.
	Continuous Straight Lines
	Keep on clicking to make continuous straight lines. Right click means the end of it but it does not make a closed area. Consequently, you cannot fill the area with color.
	Spline curve
	Keep on clicking to make a continuous line but this time a curved line. You can make a smooth curve that goes along the clicked points. Just like Continuous Straight Lines, you cannot fill the area with color, since the area is not closed.
	Wire
	Drag and the line will stick to a line edge of the picture. Release the mouse button and the line will end. This makes a closed area. You can change the shape by dragging the tiny squares, and you can move the area by dragging the inside of the area.
	Closed Area
	Click and it will make a selection of the same or similar color in the neighborhood. Here I clicked the center of the face and the skin color is selected. You can change the setting of this function by the O-panel. Increase the figure of "RANGE" and the color detection becomes loose, which means that less similar color starts to get selected, too. "BORDER" determines which layer to use for color detection. Clicking with [SHIFT] key down can select plural distant areas.
	Deselect Cancel selection. You can re-select the canceled area by clicking [View]-[Selection History] in the top menu.

2.Show outside border

This is to distinguish the selected area from non-selection area.

This is the default setting: "Darken" outside.

This is "Check."

You can choose whichever you like, "Darken" or "Check."
I personally do not use "Check" because this tends to tire my eyes...

This is "Hide." This might be the setting that bothers you the least, but only the selection lines are your clue now.

When you choose this setting, remember to cancel the selection when you work is done.

This option changes every time you click this icon or you can do the same by clicking [Selection] - [Show outside border] from the top menu.
