EBaseROI::HitTest
Detects if the cursor is placed over one of the dragging handles.
Namespace: Euresys::Open_eVision_2_5
[C++]
Euresys::Open_eVision::EDragHandle HitTest(
OEV_INT32 x,
OEV_INT32 y,
float zoomX,
float zoomY,
float panX,
float panY
)
Parameters
x
x-coordinate of the mouse cursor.
y
y-coordinate of the mouse cursor.
zoomX
Must be set to the same horizontal zooming factor as the one used when drawing. By default, true scale is used.
zoomY
Must be set to the same vertical zooming factor as the one used when drawing. By default, true scale is used.
panX
Must be set to the same horizontal pan offset factor as the one used when drawing. By default, true scale is used.
panY
Must be set to the same vertical pan offset as the one used when drawing. By default, true scale is used.
Remarks
Returns a handle identifier, as defined by EDragHandle. If zooming and/or panning were used when drawing the ROI, the same values must be used with EBaseROI::HitTest and EBaseROI::Drag.
EBaseROI.HitTest
Detects if the cursor is placed over one of the dragging handles.
