Hello, I have requirement of saving draw annotation points to db and send it to server. And also delete them from db as soon as erase is triggered. I am able to get draw points on commitAnnotation()
public void commitAnnotation() {
ArrayList<DrawPoints> points=new ArrayList<DrawPoints>();
try {
mPDFView.docLock(true);
pdftron.PDF.Rect rect = getShapeBBox();
if (rect != null) {
float sx = mPDFView.getScrollX();
float sy = mPDFView.getScrollY();
pdftron.PDF.Annots.Ink ink = pdftron.PDF.Annots.Ink.create(mPDFView.getDoc(), rect);
int pathIdx = 0;
ListIterator<LinkedList<PointF>> itrPaths = mStrokes.listIterator(0);
while (itrPaths.hasNext()) {
LinkedList<PointF> path = itrPaths.next();
ListIterator<PointF> itr = path.listIterator(0);
double[] pts = new double[2];
pdftron.PDF.Point p = new pdftron.PDF.Point();
int pointIdx = 0;
while (itr.hasNext()) {
PointF p_ = itr.next();
DrawPoints drawPoints=new DrawPoints();
pts = mPDFView.convScreenPtToPagePt(p_.x - sx, p_.y - sy, mPageForFreehandAnnot);
p.x = pts[0];
p.y = pts[1];
ink.setPoint(pathIdx, pointIdx++, p);
drawPoints.setX(p.x);
drawPoints.setY(p.y);
drawPoints.setPathindex(pathIdx);
drawPoints.setPointindex(pointIdx);
points.add(drawPoints);
}
pathIdx++;
}
setStyle(ink);
ink.refreshAppearance();
Page page = mPDFView.getDoc().getPage(mPageForFreehandAnnot);
page.annotPushBack(ink);
mAnnot = ink;
mAnnotPageNum = mPageForFreehandAnnot;
buildAnnotBBox();
mPDFView.update(mAnnot, mAnnotPageNum); // Update the region where the annotation occupies.
}
mPaint.setStrokeJoin(oldStrokeJoin);
mPaint.setStrokeCap(oldStrokeCap);
} catch (Exception ex) {
mNextToolMode = ToolManager.e_pan;
} finally {
mPDFView.docUnlock();
mStrokePoints.clear();
mStrokes.clear();
}
if(mListener!=null){
mListener.getStrokePoints(points);
}else{
Log.e(TAG, " No Listener Registered ");
}
mPDFView.waitForRendering();
}
But when I try to erase, points drawn and erased points differ.
Here is the erased method where I added log
public boolean onMove(MotionEvent e1, MotionEvent e2, float x_dist, float y_dist) {
float x = e2.getX() + mPDFView.getScrollX();
float y = e2.getY() + mPDFView.getScrollY();
// Don't allow the annotation to go beyond the page
if (mPageCropOnClientF != null) {
if (x < mPageCropOnClientF.left) {
x = mPageCropOnClientF.left;
} else if (x > mPageCropOnClientF.right) {
x = mPageCropOnClientF.right;
}
if (y < mPageCropOnClientF.top) {
y = mPageCropOnClientF.top;
} else if (y > mPageCropOnClientF.bottom) {
y = mPageCropOnClientF.bottom;
}
}
