Efficient image synthesis

A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

• selecting a background image from a plurality of source images;
• selecting one or more foreground elements from a plurality of source files, wherein the foreground elements include at least one of a foreground image or a foreground text;
• dividing at least a portion of the selected background image to one or more sub-regions for displaying the one or more selected foreground elements, wherein each sub-region is used for displaying at least one foreground element;
• determining a display format and a display location for each of the one or more foreground elements;
• and
• synthesizing the one or more foreground elements to the corresponding one or more sub-regions of the background image based on the display format and the display location.

A computer-implemented system, comprising:

• one or more computers;
• and
• one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing instructions that, when executed by the one or more computers, perform operations comprising:
• selecting a background image from a plurality of source images;
• selecting one or more foreground elements from a plurality of source files, wherein the foreground elements include at least one of a foreground image or a foreground text;
• dividing at least a portion of the selected background image to one or more sub-regions for displaying the one or more selected foreground elements, wherein each sub-region is used for displaying at least one foreground element;
• determining a display format and a display location for each of the one or more foreground elements;
• and
• synthesizing the one or more foreground elements to the corresponding one or more sub-regions of the background image based on the display format and the display location.
