Size. It's the diameter of the brush. All similar colors will be selected, considering the edges of the objects and the value of the Tolerance parameter.
Tolerance. When the value of this parameter is increased, more colors are included in the selected area. If it is set to 0 the brush selects only the areas where it's applied.

The standard selection tools are intended for creating geometric shapes and freeform selections.

From Center. The check-box lets creating a selection (a rectangle or an ellipse) using a start point, where the cursor is, as a center. Otherwise, selections are created from a corner.
Style. You can specify a size of a selection:
Normal. The size of a selection is determined by dragging the cursor.
Fixed Size. This option lets you create a selection with exact dimensions (height and width, in pixels).
Fixed Ratio. The ratio of height and width of a selection remains fixed.

Use the following tools options to adjust the selection:

	 	The tool's parameters:
Size (1-300). Diameter of the tool.
Hardness (0-100). The amount of blurriness of the outer edge. The higher the value, the harder the brush edge is.
Strength (1-100). The intensity of smearing the paint in the brush stroke. The higher the value, the more color is smeared.

The tool's parameters:
Size (1-1000). The maximum width of a line drawn with the brush.
Hardness (0-100). The blurriness of the tool's edges. The less the value the more blurry the tool's edges become. At value 100% the border between the brush's edges and the background is very distinct; at lower values the transition between these areas is smoother.
Strength (1-100). The degree of restoration to the original state. At lower values there will be less restoration and more blending with the effect; at values near 100% the original condition will be restored more completely.
