Method Detail

onInit

public void onInit(ReaderView readerView,
                   PageView pageView,
                   CPDFPage tpdfPage,
                   CPDFInkAnnotation pdfAnnotation)

Description copied from interface: IAnnotationImpl

Initialization, set initial value of CPDFReaderView in current class instance, CPDFPageView, CPDFPage, CPDFAnnotation.

Specified by:

onInit in interface IAnnotationImpl<CPDFInkAnnotation>

Overrides:

onInit in class CPDFBaseAnnotImpl<CPDFInkAnnotation>

Parameters:

readerView - Used for showing View in the whole document

pageView - Used for showing View of each page in the document

tpdfPage - Page object of document, more: CPDFPage

pdfAnnotation - Annotation object of document, more: CPDFAnnotation

onGetAnnotation

public CPDFInkAnnotation onGetAnnotation()

Description copied from interface: IAnnotationAttrChange

Gets the currently binding annotation instance

Specified by:

onGetAnnotation in interface IAnnotationAttrChange<CPDFInkAnnotation>

Returns:

Returns annotation instance, extend fromCPDFAnnotation

onAnnotAttrChange

public void onAnnotAttrChange()

Description copied from interface: IAnnotationAttrChange

Called when annotation attribute changes

Specified by:

onAnnotAttrChange in interface IAnnotationAttrChange<CPDFInkAnnotation>

eraseDraw

public void eraseDraw(float x,
                      float y)

Eraser trajectory, erases points from the hand-drawn path. Algorithm description: 1. The eraser trajectory consists of a series of connected points, and the erase area is a circle with a radius of `radius` centered at each point; 2. The algorithm for erasing points in `mDrawing`: For each pair of adjacent points on the same line, draw a segment and calculate the intersection points between the segment and the circle: (1) If both endpoints of the segment are outside the circle and there are two intersection points, one intersection point becomes the end of the previous line, and the other becomes the start of the next line; (2) If one endpoint is outside the circle and the other is inside, the point inside the circle is erased, and the intersection point is added to the line; (3) If both endpoints are inside the circle, both points are erased.
