Pixel-based techniques for combining vector graphics shapes

A non-transitory computer readable storage medium including instructions stored thereon which, when executed by a processor, cause the processor to:

• receive a selection of an operation type and a selection of a plurality of vector graphics shapes to be combined based on the operation type, the operation type including one of a unite operation, an intersect operation, a minus front operation, a minus back operation, and an exclude overlap operation;
• identify a dominant shape based on the operation type;
• apply stroke and fill properties associated with the dominant shape to each of the plurality of vector graphics shapes;
• initialize a buffer at least as large as a bounding box associated with the plurality of vector graphics shapes, the buffer storing pixels inside the bounding box;
• and
• populate each pixel of the buffer with values representing pixel types determined from the plurality of vector graphics shapes based on the operation type.

A system comprising:

• a computing device including a memory, and at least one processor, the computing device implementing a vector shape manipulation system,
• wherein the memory includes instructions stored thereon which, when executed, cause the vector shape manipulation system to:
• receive a selection of an operation type and a selection of a plurality of vector graphics shapes to be combined based on the operation type, the operation type including one of a unite operation, an intersect operation, a minus front operation, a minus back operation, and an exclude overlap operation;
• identify a dominant shape based on the operation type;
• apply stroke and fill properties associated with the dominant shape to each of the plurality of vector graphics shapes;
• initialize a buffer at least as large as a bounding box associated with the plurality of vector graphics shapes, the buffer storing pixels inside the bounding box;
• and
• populate each pixel of the buffer with values representing pixel types determined from the plurality of vector graphics shapes based on the operation type.
