Adjusting blurry vector-based lines during movement

A non-transitory computer readable storage medium comprising instructions that, when executed by at least one processor, cause a computing device to:

• receive a command to move a digital illustration, the digital illustration comprising a first axial-line segment and a second axial-line segment;
• determine that the first axial-line segment appears blurry before moving the digital illustration according to the command and that translating the first axial-line segment relative to a pixel grid would sharpen an appearance of the first axial-line segment;
• in response to determining that translating the first axial-line segment relative to a pixel grid would sharpen the appearance of the first axial-line segment, generate a translation vector that would translate the digital illustration a fraction of a pixel to sharpen the appearance of the first axial-line segment;
• and
• in response to receiving the command to move the digital illustration and determining that the first axial-line segment appears blurry before moving the digital illustration, move the digital illustration to a position that sharpens the appearance of the first axial-line segment by translating the digital illustration according to the translation vector and the command.

A system for sharpening blurry digital illustrations without distorting corresponding digital-illustration shapes or dimensions comprising:

• a memory comprising a digital illustration, the digital illustration comprising a first axial-line segment and a second axial-line segment;
• a computing device comprising instructions thereon that, when executed by at least one processor, cause the system to:
• receive a command to move the digital illustration;
• determine that the first and second axial-line segments appear blurry before moving the digital illustration according to the command;
• determine that translating the first and second axial-line segments relative to a pixel grid would sharpen an appearance of the first and second axial-line segments;
• in response to determining that translating the first and second axial-line segments relative to a pixel grid would sharpen the appearance of the first and second axial-line segments, generate a translation vector that would translate the first and second axial-line segments a fraction of a pixel to sharpen the appearance of the first and second axial-line segments;
• and
• in response to receiving the command to move the digital illustration and determining that the first and second axial-line segments appear blurry before moving the digital illustration, move the digital illustration to a position that sharpens the appearance of the first and second axial-line segments by translating the first and second axial-line segments the fraction of a pixel according to the translation vector and translating the digital illustration an integer number of pixels according to a distance indicated by the command.
