Abstract
Aspects of subject technology provide systems and methods for electronic drawing with handwriting recognition. An electronic device may include one or more processors configured to receive a drawing stroke input, generate a bitmap of values that represent the drawing stroke input, render the bitmap for display by a display of the device, generate a vector representation of the drawing stroke input, and store the generated bitmap and the generated vector representation.
Claims28
A device, comprising:
- at least one processor configured to:
- receive a drawing stroke input;
- generate a vector representation of the drawing stroke input;
- generate a bitmap of values based on the drawing stroke input and independent of the vector representation;
- render the bitmap for display by a display of the device;
- store the generated bitmap to facilitate bitmap editing operations;
- and
- store the generated vector representation to facilitate recognition of text associated with the drawing stroke input.
A computer-implemented method, comprising:
- receiving a drawing stroke input;
- generating a bitmap of values that represent the drawing stroke input;
- rendering the bitmap for display by a display of an electronic device;
- generating a vector representation of the drawing stroke input based on the bitmap;
- storing the generated bitmap for bitmap editing operations;
- and
- storing the generated vector representation of the bitmap, to facilitate character recognition with respect to the drawing stroke input.
A non-transitory computer-readable medium comprising instructions, which when executed by at least one computing device, cause the at least one computing device to perform operations comprising:
- receiving a drawing stroke input;
- generating a handwriting-recognition vector corresponding to the drawing stroke input to facilitate handwriting recognition operations for the drawing stroke input;
- and
- generating a plurality of drawing vectors corresponding to the drawing stroke input to facilitate editing of a rendering of the drawing stroke input.
