Partitioning high resolution images into sub-images for display

A computer-implemented method comprising:

• determining, responsive to ascertaining that a size of a primary image exceeds a threshold image size for a system, that the primary image is to be partitioned into multiple sub-images;
• determining a first dimension for at least one of the multiple sub-images based on a guide parameter, the guide parameter calculated as a mathematical function of both a number of bytes-per-pixel for the system and a graphics memory threshold for the system;
• determining a second dimension for the at least one of the multiple sub-images based on an amount of graphics memory up to the graphics memory threshold available to generate the at least one of the multiple sub-images using the first dimension;
• and
• partitioning the primary image into the multiple sub-images including the at least one of the multiple sub-images.

A system comprising:

• one or more processors;
• and
• one or more computer readable storage media comprising computer-executable instructions that are executable by the one or more processors to perform operations including:
• determining that an image that exceeds a threshold image size for a system is to be partitioned into multiple sub-images;
• determining a first dimension for at least one of the multiple sub-images based on a number of bytes-per-pixel for the system and a graphics memory threshold for the system;
• determining a second dimension for the at least one of the multiple sub-images based on an amount of graphics memory up to the graphics memory threshold available to generate the at least one of the multiple sub-images using the first dimension, including determining how large the second dimension can be before the at least one of the multiple sub-images exceeds the graphics memory threshold for the system;
• and
• partitioning the image into the multiple sub-images including the at least one of the multiple sub-images being sized using the first dimension and the second dimension.
