Image forming apparatus having a virtual machine for performing processing by issuing a processing request to a graphics library via an API

摘要

When a graphics library performs transparency calculation even if transparency processing is unnecessary, or when the graphics library does not issue an effective rendering instruction to a GPU, no satisfactory rendering performance can be obtained even in a virtual machine which runs in combination with the graphics library. To solve this, the virtual machine uses the graphics library to or not to perform transparency processing in accordance with a content to be rendered. The virtual machine uses the graphics library to issue an effective rendering instruction to the GPU.
