Methods for visual content processing , and systems and computer program codes thereto

A system for creating visual content to be output in a layered manner, the system comprising:

• one or more processors
• a memory including computer program code the memory and the computer program code configured to, with the processor, cause the system at least to perform:
• receive at least two image content items,
• categorize the received image content items on a basis of content type to at least two categories,
• render the image content items in each of the at least two categories into corresponding number of raster canvases, each raster canvas representing image content data in one category,
• d) compress the image content data in each of the raster canvases, wherein the compression method for each of the raster canvases is selected on a basis of the image content data in the raster canvas to be compressed,
• e) storing into the memory the compressed image content data of each of the raster canvases.

A computer implemented method for creating visual content to be output, the method comprising:

• a) receiving one or more image content items,
• b) categorizing the received one or more image content items on a basis of content type to a category,
• c) rendering the one or more image content items in the category into a raster canvas, the raster canvas representing image content data in the category,
• d) compressing the image content data in the raster canvas, wherein the compression method for the raster canvas is selected on a basis of the image content data in the raster canvas to be compressed,
• e) storing the compressed image content data of the raster canvas.
