EOCR2::HitTestLine

Tests the cursor position for the presence of a line. If one is present under the cursor, it returns true and fills the EOCR2Line object In a general content, the term object should be understood with the meaning of a class instance. In EasyObject, an object is a maximally-sized area of adjacent connected pixels belonging to the layer foreground. passed as parameter.

Parameters

line

Object to fill if a line was detected under the cursor.

Horizontal position of the cursor.

Vertical position of the cursor.

zoomX

Horizontal zooming factor. By default, true scale is used.

zoomY

Vertical zooming factor. If set to 0 (default), the horizontal zooming factor is used instead, so as to provide isotropic zooming.

panX

Horizontal panning value expressed in pixels. By default, no panning occurs.

panY

Vertical panning value expressed in pixels. By default, no panning occurs.
