Abstract
According to one embodiment, an electronic device performs a process of a process of erasing one or more strokes from the handwritten document in response to an operation for collectively erasing at least one stroke corresponding to an erasing are. The erasing area is determined by at least a track size of an additional stroke received in an erasing mode. The electronic device executes, when the erasing area is larger than a first size, a first process of erasing at least one stroke distinguishable as an object to be erased in a first erasing manner. The electronic device executes, when the erasing are is not larger than the first size, a second process of erasing at least one stroke in a second erasing manner different from the first erasing manner.
Claims15
An electronic device comprising:
- a display controller configured to display on a screen a handwritten document comprising a plurality of strokes;
- circuitry configured to perform a process of erasing one or more strokes from the handwritten document in response to an operation for collectively erasing at least one stroke corresponding to an erasing are, the erasing area determined by at least a track size of an additional stroke received in an erasing mode,
- wherein the circuitry is configured to execute, when the erasing area is larger than a first size, a first process of erasing at least one stroke distinguishable as an object to be erased in a first erasing manner,
- wherein the circuitry is configured to execute, when the erasing are is not larger than the first size, a second process of erasing at least one stroke in a second erasing manner different from the first erasing manner.
A method comprising:
- displaying on a screen a handwritten document comprising a plurality of strokes;
- erasing one or more strokes from the handwritten document in response to an operation for collectively erasing at least one stroke corresponding to an erasing are, the erasing area determined by at least a track size of an additional stroke received in an erasing mode;
- executing, when the erasing area is larger than a first size, a first process of erasing at least one stroke distinguishable as an object to be erased in a first erasing manner;
- and
- executing, when the erasing are is not larger than the first size, a second process of erasing at least one stroke in a second erasing manner different from the first erasing manner.
A non-transitory computer-readable medium storing a computer program executable by a computer, the computer program causing the computer to execute functions of:
- displaying on a screen a handwritten document comprising a plurality of strokes;
- erasing one or more strokes from the handwritten document in response to an operation for collectively erasing at least one stroke corresponding to an erasing are, the erasing area determined by at least a track size of an additional stroke received in an erasing mode;
- executing, when the erasing area is larger than a first size, a first process of erasing at least one stroke distinguishable as an object to be erased in a first erasing manner;
- and
- executing, when the erasing are is not larger than the first size, a second process of erasing at least one stroke in a second erasing manner different from the first erasing manner.
