Tutorial: AKVIS MultiBrush

Eraser

The Eraser is a tool that alters the transparency of an image. Processed sections are shown as transparent areas, with a checkerboard background.

Attention! When saving your file, do not choose formats that do not support transparency (JPEG), as the transparent areas will be replaced by the color white.

The tool's parameters can be changed in the Settings Panel. To change the value of a parameter, enter a numerical value into the parameter's field and press Enter (Macintosh: Return) or adjust the slider.

Diameter (1-500). The maximum width of the transparent line which the eraser leaves behind (in pixels).
Hardness (0-100). The amount of blurriness of the brush's edge. As the value of this parameter increases the edge of the brush becomes harder. Near 100% the border between erased and unerased areas will be more distinct; at lower values the boundary between these areas will be smoother.

Removing Some of the Drawing With the Eraser

Hard Edged Eraser Soft Edged Eraser

Hardness = 100% Hardness = 20%

Strength (1-100). The amount of influence on an image. As this parameter's value is increased, the degree of transparency left by the brush increases.

Removing the Boundary With the Eraser

High Strength Weak Strength

Strength = 100% Strength = 45%

Spot Spacing (5-200). The distribution of elements, of which the transparent line is comprised. Increasing this parameter creates a line made up of a succession of circles, the spacing of which depends on the value of the parameter.

The Interaction of the Processed Image With the New Background

Applying the Eraser to an Image

In order to erase in a straight line, select the starting point of the line with the left mouse button, then, press and hold down Shift, move the cursor to the desired endpoint, and release Shift. If Shift is not released, then successive lines will be drawn to each point where the mouse is clicked.
