S PEN SDK WORKSHOP
HOW TO: ADD THE CANVAS
import com.samsung.android.sdk.pen.*;
Spen spenPackage = new Spen(); //New instancespenPackage.initialize(this); // Init package
//SpenSurfaceView is like a surface on which Notes are drawnmSpenSurfaceView = new SpenSurfaceView (mContext);spenViewLayout.addView(mSpenSurfaceView);
//SpenNoteDoc is like a notebook and SPenPageDoc are individual pages in the NotebookmSpenNoteDoc = new SpenNoteDoc (mContext, width, rect.height );SpenPageDoc SpenPageDoc = mSpenNoteDoc.appendPage(); mSpenPageDoc.setBackgroundColor(0xFFD6E6F5);mSpenPageDoc.clearHistory();
mSpenSurfaceView.setPageDoc(mSpenPageDoc, true);
S PEN SDK WORKSHOP
ERASER, PEN MODES & HISTORY MGMT
// Pen ModespenSurfaceView. setToolTypeAction(SpenSettingViewInterface.TOOL_SPEN, SpenSurfaceView.ACTION_STROKE);
// Eraser ModespenSurfaceView. setToolTypeAction(SpenSettingViewInterface.TOOL_SPEN, SpenSurfaceView.ACTION_ERASER);
// Undo and Redoif(spenPageDoc.isUndoable ()) {
spenSurfaceView.updateUndo (spenPageDoc.undo () );};
// Pen settingsSpenSettingPenInfo penInfo = new SpenSettingPenInfo();penInfo.color = Color.BLUE; //size , pen type are other optionsspenSurfaceView.setPenSettingInfo(penInfo);
