boolean GNOME::Magnifier::ZoomRegion::setMagFactor | ( | in float | magX, | |
in float | magY | |||
) |
Set the current x and y magnification ratio.
(Convenience method for setting mag-factor-x and mag-factor-y properties). Note that if the zoom region's target hasn't yet been realized or mapped to the display, we will not be able to detect failure, so a return of TRUE must be taken on advisement if the operation is performed on a newly-created zoom region.
magX | the magnification factor in the x direction for the specified region. | |
magY | the magnification factor in the x direction for the specified region. |
void GNOME::Magnifier::ZoomRegion::getMagFactor | ( | out float | magX, | |
out float | magY | |||
) |
Get the current x and y magnification ratios.
(Convenience method for getting mag-factor-x and mag-factor-y properties).
magX,: | the magnification factor in the x direction for the specified region. | |
magY,: | the magnification factor in the x direction for the specified region. |
Bonobo::PropertyBag GNOME::Magnifier::ZoomRegion::getProperties | ( | ) |
Gets the current property settings for this ZoomRegion.
Properties managed by the ZoomRegion include "smoothing-type", "contrast", "inverse-video", "border-size", "border-color", "x-alignment", "y-alignment", "is-managed", "viewport", "mag-factor-x", "mag-factor-y".
oneway void GNOME::Magnifier::ZoomRegion::setROI | ( | in RectBounds | bounds | ) |
Set the region of interest for the magnifier.
bounds,: | the ROI bounding box |
void GNOME::Magnifier::ZoomRegion::markDirty | ( | in RectBounds | dirtyRegion | ) |
Mark the zoom region or a sub-region 'dirty' and in need of updating.
dirtyRegion,: | the bounding box of the dirty region. |
RectBounds GNOME::Magnifier::ZoomRegion::getROI | ( | ) |
void GNOME::Magnifier::ZoomRegion::moveResize | ( | in RectBounds | bounds | ) |
Move and resize the specified zoom region on the target display.
(Convenience method for setting "viewport" property).
bounds,: | the bounding box, in target display coordinates, of the ZoomRegion's display viewport. |
void GNOME::Magnifier::ZoomRegion::dispose | ( | ) |
Remove the specified zoom region from the magnifier and destroy it.
oneway void GNOME::Magnifier::ZoomRegion::setPointerPos | ( | in long | mouse_x, | |
in long | mouse_y | |||
) |
Set the position where the mouse pointer is to be drawn in this zoom-region, in screen coordinates.
mouse_x,: | the x screen coordinate of the pointer hotspot | |
mouse_y,: | the y screen coordinate of the pointer hotspot |
void GNOME::Magnifier::ZoomRegion::setContrast | ( | in float | R, | |
in float | G, | |||
in float | B | |||
) |
Set the zoom region image contrast.
Set the contrast applied to each image component (red, green and blue). The input for each component must be in the range -1 and 1, otherwise they will be clamped to this interval. The value -1 means reduce 100% the contrast, resulting in a gray image. The value 1 means increase 100% the contrast, resulting in the R, G and B values being black or white. The value 0 means no change in contrast.
R | the amount of red in the contrasted image. | |
G | the amount of green in the contrasted image. | |
B | the amount of green in the contrasted image. |
void GNOME::Magnifier::ZoomRegion::getContrast | ( | out float | R, | |
out float | G, | |||
out float | B | |||
) |
Get the zoom region image contrast.
Get the contrast applied to each image component (red, green and blue).
R | the amount of red in the contrasted image. | |
G | the amount of green in the contrasted image. | |
B | the amount of green in the contrasted image. |
void GNOME::Magnifier::ZoomRegion::setBrightness | ( | in float | R, | |
in float | G, | |||
in float | B | |||
) |
Set the zoom region image brightness.
Set the brightness applied to each image component (reg, green and blue). The input for each component must be in the range between -1 and 1, if the are bigger or lower then this range, the value will be clamped to the interval. The value -1 means reduce 100% the brightness, resulting in a black image. The value 1 means increase 100% the brightness, resulting in a white image.
R | the brightness applied to the red component. | |
G | the brightness applied to the green component. | |
B | the brightness applied to the blue component. |
void GNOME::Magnifier::ZoomRegion::getBrightness | ( | out float | R, | |
out float | G, | |||
out float | B | |||
) |
Get the zoom region image brightness.
Get the brightness applied to each image component (red, green and blue).
R | the brightness applied to the red component. | |
G | the brightness applied to the green component. | |
B | the brightness applied to the blue component. |
