<filename extension> X bit map. The filename extension for files containing bitmaps for use in the X Window System. These are actually include files which can be #include'd into C program source to define images as initialised data. (1995-03-14)

In computer graphics, the X Window System used X BitMap (XBM), a plain text binary image format, for storing cursor and icon bitmaps used in the X GUI. The XBM format is superseded by XPM, which first appeared for X11 in 1989.

The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable.

<graphics, file format> (WBMP) A bitmap for display on a WAP mobile phone. Currently (2001) the only type of WBMP file defined is a simple black-and-white image file with one bit per pixel and no compression. [WAP Forum (http://wapforum.org/), "WAP-190-WAE-Spec" or "Wireless Application Protocol, Wireless Application Environment Specification"]. (2001-05-23)

<graphics, file format> (DIB) An image format in which the sequence and depth of pixels in the file is not specifically related to their layout in any particular device. This allows any device dependent bitmap (DDB) image to be converted to or DIB format without loss of information, and this can then later be converted to other DDB formats for, e.g., printing or display. Rather than requiring converters from each DDB format to all other formats, only converters to and from DIB are needed. DIB images are normally transferred in metafiles, bmp files, and the clipboard. Transferring colour bitmaps from one device to another was not possible in versions of Microsoft Windows earlier than 3.0. Application programs can build DIB images without any interaction with Windows. If Windows lacks a drawing primitive, the application can simulate it directly into the DIB instead of using the existing graphics device interface (GDI) primitives. Unfortunately, under Windows versions 3.0 and 3.1, GDI cannot perform output operations directly to a DIB. Conversion between DIB and DDB is performed by the {device driver}. Where the driver does not have this facility, the conversion is performed by GDI but only in monochrome. DIBs are slower to use than device dependent bitmaps due to the conversions required.

A screen is a blocking move by an offensive player in which they stand beside or behind a defender in order to free a teammate to either shoot a pass or drive in to score. In basketball and field lacrosse, it is also known as a pick.

In computing, a bitmap is a mapping from some domain (for example, a range of integers) to bits. It is also called a bit array or bitmap index.

A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience. Projection screens may be permanently installed, as in a movie theater; painted on the wall;Acrylic paint used to make a movie screen on the wall (see screen goo) or portable with tripod or floor rising models as in a conference room or other non-dedicated viewing space.
