'proportional'

Mouse Tracking Mode

Determines the position of the magnified mouse image within the magnified view and how it reacts to system mouse movement. The values are • none: no mouse tracking; • centered: the mouse image is displayed at the center of the zoom region (which also represents the point under the system mouse) and the magnified contents are scrolled as the system mouse moves; • proportional: the position of the magnified mouse in the zoom region is proportionally the same as the position of the system mouse on screen; • push: when the magnified mouse intersects a boundary of the zoom region, the contents are scrolled into view. 'proportional'

Focus Tracking Mode

Determines the position of the focused widget within magnified view. The values are: • none: no focus tracking • centered: the focused image is displayed at the center of the zoom region (which also represents the point under the system focus) and the magnified contents are scrolled as the system focus moves • proportional: the position of the magnified focus in the zoom region is proportionally the same as the position of the system focus on screen • push: when the magnified focus intersects a boundary of the zoom region, the contents are scrolled into view 'centered'

Caret Tracking Mode

Determines the position of the caret within magnified view. The values are: • none: no caret tracking • centered: the image of the caret is displayed at the center of the zoom region (which also represents the point under the system caret) and the magnified contents are scrolled as the system caret moves • proportional: the position of the magnified caret in the zoom region is proportionally the same as the position of the system caret on screen • push: when the magnified caret intersects a boundary of the zoom region, the contents are scrolled into view 'full-screen'

Screen position

The magnified view either fills the entire screen, or occupies the top-half, bottom-half, left-half, or right-half of the screen. 2.0

Magnification factor

The power of the magnification. A value of 1.0 means no magnification. A value of 2.0 doubles the size. false

Enable lens mode

Whether the magnified view should be centered over the location of the system mouse and move with it. false

Scroll magnified contents beyond the edges of the desktop

For centered mouse tracking, when the system pointer is at or near the edge of the screen, the magnified contents continue to scroll such that the screen edge moves into the magnified view. false

Show or hide crosshairs

Enables/disables display of crosshairs centered on the magnified mouse sprite. 8

Thickness of the crosshairs in pixels

Width in pixels of the vertical and horizontal lines that make up the crosshairs. '#ff0000'

Color of the crosshairs

The color of the the vertical and horizontal lines that make up the crosshairs. 0.66

Opacity of the crosshairs

Determines the transparency of the crosshairs, from fully opaque to fully transparent. 4096

Length of the crosshairs in pixels

Determines the length in pixels of the vertical and horizontal lines that make up the crosshairs. false

Clip the crosshairs at the center

Determines whether the crosshairs intersect the magnified mouse sprite, or are clipped such that the ends of the horizontal and vertical lines surround the mouse image. false

Inverse lightness

Determines whether the lightness values are inverted: darker colors become lighter and vice versa, and white and black are interchanged. 1.0

Color Saturation

Represents a change to the color saturation, from 0.0 (grayscale) to 1.0 (full color). 0.0

Change brightness of red

Represents a change to the default brightness of the red component. Zero indicates no change, values less than zero indicate a decrease, and values greater than zero indicate an increase. 0.0

Change brightness of green

Represents a change to the default brightness for the green component. Zero indicates no change, values less than zero indicate a decrease, and values greater than zero indicate an increase. 0.0

Change brightness of blue

Represents a change to the default brightness for the blue component. Zero indicates no change, values less than zero indicate a decrease, and values greater than zero indicate an increase. 0.0

Change contrast of red

Represents a change to the default contrast of the red component. Zero indicates no change in contrast, values less than zero indicate a decrease, and values greater than zero indicate an increase. 0.0

Change contrast of green

Represents a change to the default contrast of the green component. Zero indicates no change in contrast, values less than zero indicate a decrease, and values greater than zero indicate an increase. 0.0

Change contrast of blue

Represents a change to the default contrast of the blue component. Zero indicates no change in contrast, values less than zero indicate a decrease, and values greater than zero indicate an increase.
