Editing a graphic object in a vector representation to improve crisp property in raster representation

A computer system, comprising:

• means for generating a graphic object, wherein the graphic object has a vector format and a raster format;
• means for detecting that an internal line of the graphic object has a blurriness when rendered in the raster format, wherein the raster format identifies a first location of the internal line on a pixel grid, and wherein the blurriness is associated with a first pixel distribution of the internal line at the first location on the pixel grid;
• means for reducing the blurriness of the internal line by at least:
• computing a first offset between the first location and a second location on the pixel grid, wherein the second location corresponds to a second pixel distribution of the internal line on the pixel grid, and
• translating the graphic object on the pixel grid by the first offset;
• means for computing a second offset between an external line of the graphic object at a translated location and a third location on the pixel grid, wherein the second offset is computed based on a blurriness of the external line;
• and
• means for scaling the graphic object by the second offset based on the vector format.

A non-transitory computer-readable storage medium storing computer-readable instructions that, upon execution on a computer system, cause the computer system to perform operations comprising:

• generating a graphic object that has a vector format and a raster format;
• detecting that an internal line of the graphic object has a blurriness when rendered in the raster format, wherein the raster format identifies a first location of the internal line on a pixel grid, and wherein the blurriness is associated with a first pixel distribution of the internal line at the first location on the pixel grid;
• reducing the blurriness of the internal line by at least:
• computing a first offset between the first location and a second location on the pixel grid, wherein the second location corresponds to a second pixel distribution of the internal line on the pixel grid, and
• translating the graphic object on the pixel grid by the first offset;
• computing a second offset between an external line of the graphic object at a translated location and a third location on the pixel grid, wherein the second offset is computed based on a blurriness of the external line;
• and
• scaling the graphic object by the second offset based on the vector format.
