System and method to check the correct rendering of a font

A system for determining a correct rendering of a candidate entity, the system comprising:

• a memory storing one or more reference patterns;
• a rendering engine that renders a first combined image including an image of a reference entity and that renders a second combined image including an image of a candidate entity, wherein the reference entity is bound by a first grid including one or more grid cells and the candidate entity is bound by a second grid including one or more grid cells;
• a pattern module that reads the memory, identifies from the read memory a reference pattern for the reference entity in accordance with filled, partially filled, and empty grid cell content representing the reference entity within the first grid, that identifies a candidate pattern for the candidate entity in accordance with filled, partially filled, and empty grid cell content representing the candidate entity within the second grid, and that maps corresponding grid cell patterns of the reference and candidate entities;
• and
• a validation module that determines a variance measurement between the mapped grid cell patterns of the reference and candidate entities and determines, based on the variance measurement, whether the candidate entity is a correct rendering in accordance with the reference entity.

A machine-readable medium comprising a plurality of machine-readable instructions that when executed by one or more processors is adapted to cause the one or more processors to perform a method comprising:

• identifying a first combined image including an image of a reference entity, wherein the reference entity is bound by a first grid including one or more grid cells;
• identifying a reference pattern for the reference entity in accordance with filled, partially filled, and empty grid cell content representing the reference entity within the first grid;
• rendering a second combined image including an image of a candidate entity, wherein the candidate entity is bound by a second grid including one or more grid cells;
• identifying a candidate pattern for the candidate entity in accordance with filled, partially filled, and empty grid cell content representing the candidate entity within the second grid;
• mapping corresponding grid cell patterns of the reference and candidate entities;
• determining a variance measurement between the mapped grid cell patterns of the reference and candidate entities;
• and
• determining, based on the variance measurement, whether the candidate entity is a correct rendering in accordance with the reference entity.
