Abstract
Presenting a slide. Anticipating a slide to be selected for display. Receiving data of the anticipated slide in an unconstructed format. Constructing the anticipated slide from the received data. Caching the constructed slide. Pre-drawing the constructed slide in construction memory. Receiving instructions to display a slide. In the event that the instructed slide is the cached and pre-drawn slide, rendering the pre-drawn slide to display memory.
Claims15
A computer-implemented method for slide presentation, the method comprising:
- displaying a first slide at a presentation device;
- receiving, from an attachment server, complete Universal Content Stream text and graphics data of a second, non-consecutive, slide in an unconstructed format, the second slide having been determined, without user input, from metadata of the second slide;
- constructing, at the presentation device, the second slide from the received data via image decompression, text rendering and color conversion processing;
- caching the constructed slide in a cache of the presentation device;
- pre-drawing the constructed slide in text construction memory of the presentation device;
- receiving instructions to display a slide which is not currently in a display memory of the presentation device;
- and
- only in the event that the instructed slide is the cached and pre-drawn slide, rendering the pre-drawn slide to the display memory of the presentation device.
A computer program product for slide presentation, the computer program product comprising:
- at least one non-transitory computer readable medium;
- and
- at least one program module,
- stored on the at least one medium, and
- operative, upon execution by at least one processor for:
- displaying a first slide on a display device;
- receiving from an attachment server, complete Universal Content Stream text and graphics data of a second, non-consecutive, slide in an unconstructed format, the second slide having been determined, without user input, from metadata of the second slide;
- constructing, at the display device, the second slide from the received data via image decompression, text rendering and color conversion processing;
- caching the constructed slide in a cache of the display device;
- pre-drawing the constructed slide in text construction memory of the display device;
- receiving instructions to display a slide which is not currently in a display memory of the display device;
- and
- only in the event that the instructed slide is the cached and pre-drawn slide, rendering the pre-drawn slide to the display memory of the display device.
A system for slide presentation on a portable electronic device, the system comprising:
- at least one processor within the portable electronic device,
- at least one computer readable medium in communication with the processor;
- at least one program module,
- stored on the at least one medium, and operative upon execution by the processor for:
- displaying a first slide;
- receiving, from an attachment server, complete Universal Content Stream text and graphics data of a second slide in an unconstructed format, the second slide being non-consecutive to the first slide, the second slide having been determined, without user input, from metadata of the second slide;
- constructing, at the portable electronic device, the second slide from the received data via image decompression, text rendering and color conversion processing;
- caching the constructed slide in a cache of the portable electronic device;
- pre-drawing the constructed slide in construction memory of the portable electronic device;
- receiving instructions to display a slide which is not currently stored in a display memory of the portable electronic device;
- and
- only in the event that the instructed slide is the cached and pre-drawn slide, rendering the pre-drawn slide to the display memory of the portable electronic device.
