Wat is een XBM-bestand?

An XBM file is a bitmap image used by the X Window System (X11), a GUI used to manage networked client-server computers. It contains C code that defines the image's appearance. Primarily, XBM files contain cursor and icon images.

Developers creating C programs for the X Window System can embed XBM, or X BitMap, images into those programs. Each XBM image consists of plain text C code that looks something like the following:

#define 2x2_width 16
#define 2x2_height 16
static char 2x2_bits[] = {
0xff, 0xff, 0xff, 0xff, 0x33, 0x33, 0x33, 0x33, 0xff, 
0xff, 0xff, 0xff, 0x33, 0x33, 0x33, 0x33, 0xff, 0xff, 
0xff, 0xff, 0x33, 0x33, 0x33, 0x33, 0xff, 0xff, 0xff, 
0xff, 0x33, 0x33, 0x33, 0x33};

When displayed in a program or opened in an image viewer, an XBM file appears as a monochrome image. The image's appearance is defined by its width and height parameters as well as its static array of pixel values.

OPMERKING: The .XPM format eventually replaced the XBM format.

You can also open an XBM file with Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text editor, to view the C code the file contains.
