Reflow of handwriting content

1. A method, comprising:

accepting, in an input overlay application, handwriting ink strokes;

determining handwriting units for the handwriting ink strokes;

determining a block unit for the handwriting units;

providing margin controls in the input overlay application based on a size of the block unit;

accepting editing input associated with the block unit, wherein the editing input comprises a margin change; and

automatically reflowing the block unit in a coordinated fashion based on the margin change.

2. The method of claim 1 , wherein:

the editing input comprises an insertion gesture; and

the reflowing further comprises inserting new handwriting ink strokes as a new handwriting unit between two existing handwriting units.

3. The method of claim 2 , further comprising dynamically growing an insertion handwriting unit to accommodate the new handwriting ink strokes.

4. The method of claim 3 , wherein the reflowing comprises dynamically reflowing the handwriting units based on the insertion handwriting unit size.

5. The method of claim 1 , wherein:

the editing input comprises a deletion gesture; and

the reflowing comprises deleting one of the handwriting units and repositioning any remaining handwriting ink strokes.

6. The method of claim 1 , wherein the reflowing comprises shifting one or more handwriting units laterally.

7. The method of claim 1 , wherein the reflowing comprises shifting one or more handwriting units vertically.

8. The method of claim 1 , wherein:

the editing input comprises a drag movement of a handwriting unit; and

wherein the reflowing comprises further reflowing the block unit based on the drag movement.

9. An electronic device, comprising:

an input and display device;

a processor operatively coupled to the input and display device; and

a memory that stores instructions executable by the processor to:

accept, in an input overlay application, handwriting ink strokes;

determine handwriting units for the handwriting ink strokes;

determine a block unit for the handwriting units;

provide margin controls in the input overlay application based on a size of the block unit;

accept editing input associated with the block unit, wherein the editing input comprises a margin change; and

automatically reflow the block unedited handwriting unit in a coordinated fashion based on the margin change.

10. The electronic device of claim 9 , wherein:

the editing input comprises an insertion gesture; and

to reflow comprises inserting new handwriting ink strokes as a new handwriting unit between two existing handwriting units.

11. The electronic device of claim 10 , wherein the instructions are executable by the processor to dynamically grow an insertion handwriting unit to accommodate the new handwriting ink strokes.

12. The electronic device of claim 11 , wherein to reflow comprises dynamically reflowing the handwriting units based on the insertion handwriting unit size.

13. The electronic device of claim 9 , wherein:

the editing input comprises a deletion gesture; and

to reflow comprises deleting one of the handwriting units and repositioning any remaining handwriting ink strokes.

14. The electronic device of claim 9 , wherein to reflow comprises shifting one or more handwriting units laterally.

15. The electronic device of claim 9 , wherein to reflow comprises shifting one or more handwriting units vertically.

16. The electronic device of claim 9 , wherein:

the editing input comprises a drag movement of a handwriting unit; and

wherein to reflow comprises further reflowing the block unit based on the drag movement.

17. A product, comprising:

a non-transitory storage device having code stored therewith, the code being executable by a processor of an electronic device and comprising:

code that accepts, in an input overlay application, handwriting ink strokes;

code that determine handwriting units for the handwriting ink strokes;

code that determines a block unit for the handwriting units;

code that provides margin controls in the input overlay application based on a size of the block unit;

code that accepts editing input associated with the block unit, wherein the editing input comprises a margin change; and

code that automatically reflows the block unit in a coordinated fashion based on the margin change.
