The driver will then dither the data (in most cases this can be done by the graphics hardware for maximum performance) which is stored in the framebuffer as an 8-bit image. On displaying that 8-bit image data, HP's color recovery technology produces in real time an approximation of the original 24-bit image based on the hints provided by the ...
In Windows 8, WARP provides functionality for the "Microsoft Basic Render Driver" which replaces kernel-mode VGA driver. In Windows 8.1, WARP has been updated to support feature level 11_1 and tiled resources. [5] In Windows 10, WARP has been updated to support Direct3D 12 at feature level 12_1; under Direct3D 12, WARP also replaces the ...
Timeout Detection and Recovery or TDR is a feature of the Windows operating system (OS) introduced in Windows Vista. It detects response problems from a graphics card (GPU), and if a timeout occurs, the OS will attempt a card reset to recover a functional and responsive desktop environment .
Render Pass, introducing render pass concept in Direct3D 12, adding new APIs to be run on existing drivers and allow user mode drivers to choose optimal rendering path without heavy CPU penalty. Meta-commands , adding preview support for DirectML , a high-performance, hardware-accelerated DirectX 12 library for machine learning.
WIA is a very significant superset of the support for digital still imaging drivers that was provided by the Still Image Architecture (STI) in Windows 98.Whereas STI only provided a low-level interface for doing basic transfers of data to and from the device (as well as the invocation of an image scan process on the Windows machine through the external device), WIA provides a framework through ...
In GDI, a device context (DC) defines the attributes of text and images for the output device, e.g., screen or printer. GDI maintains the actual context. Generating the output requires a handle to the device context (HDC). After generating the output, the handle could be released. GDI uses Bresenham's line drawing algorithm to draw aliased lines.
The Direct Rendering Manager and KMS are part of the Linux kernel. The KMS does only the mode setting. Mode setting is a software operation that activates a display mode (screen resolution, color depth, and refresh rate) for a computer's display controller by using VESA BIOS Extensions or UEFI Graphics extensions (on more modern computers).
There are two graphics hardware drivers: one resides inside of the X display server.There have been several designs of this driver. The current one splits it in two portions: DIX (Device-Independent X) and DDX (Device-Dependent X) Glamor will simplify the X server, and libGL-fglrx-glx [needs update] could use the libDRM of the radeon open-source driver instead of the proprietary binary blob.
