setZoom(zoom)
E.g. ViewONE.setZoom(2.0);
Zooms to the value specified. The value is specified as a double value - 1.0 = 100% or 1
image pixel = 1 screen pixel, 2.0 = 200% or 1 image pixel = 2 screen pixels.
If used in conjunction with setXYScroll, it is advisable to use setZoomAndXYScroll instead
as problems may occur when both setZoom and setXYScroll are used together.
setZoomAndXYScroll(zoom, x, y)
E.g. ViewONE.setZoomAndXYScroll(2.0, 100, 100);
Zooms to the value specified. The value is specified as a double value - 1.0 = 100% or 1
image pixel = 1 screen pixel, 2.0 = 200% or 1 image pixel = 2 screen pixels
zoomArea(x, y, width, height, highlight, seconds)
E.g. ViewONE.zoomArea(400, 500, 100, 150, true, 2);
Zooms to an area starting at “x”, “y” which is “width” across and “height” high. If “highlight”
is set “true” then the area zoomed is also highlighted for a time specified by the “seconds”
parameter.
If “seconds” is greater than 0 then the highlight is visible for that time. If “seconds” is less
than or equal to 0 then the highlight will remain visible until the user clicks or forces a
refresh by scrolling, rotating, etc.
x, y, width, height = integers specifying image pixel values
seconds = integer specifying seconds
highlight = boolean
If the area specified is a different aspect ratio from the display area then the viewer will
attempt to fit the zoom as best it can.
setXYScroll(x, y)
E.g. ViewONE.setXYScroll(20,20);
Sets the scroll bar positions to the given values in screen pixels.
If used in conjunction with setXYScroll, it is advisable to use setZoomAndXYScroll instead
as problems may occur when both setZoom and setXYScroll are used together.
