## *default-texture-info*

The value of this variable is a standard `texture-info` object that may be used by multiple pixmaps for efficiency, if the properties of those pixmaps all happen to match those specified by this `texture-info`. In addition, this `texture-info` may be used with typical button-sized pixmaps to cause them to automatically change some of their colors to match the user's Control Panel color scheme.

The `texture-info`'s width and height are 16 pixels, its bits-per-pixel is 4 (for up to 16 colors), and its colors are those returned by default-pixmap-color-vector. These attributes are commonly used by pixmaps in `picture-button`s and `multi-picture-button`s. Since default-pixmap-color-vector is used for the colors, using this `texture-info` for such buttons will cause them to match the user's Control Panel scheme (see default-pixmap-color-vector for more info).

The invert-p property of this `texture-info` is `nil`, meaning that it is suitable for use with pixmaps that were loaded from a file with load-pixmap. (If such a pixmap matches all of the attributes of this special `texture-info`, including the color order, then this `texture-info` could be swapped in by calling (setf texture-info) on the pixmap after loading it, to cause the pixmap to match the user's Control Panel colors). If you are instead defining pixmaps as source code (with the rows of the source code matching the order of the rows in the image), then use `*default-inverted-texture-info*` instead. See that page for an example usage.

If a pixmap is created by specifying its width, height, bits-per-pixel, and invert-p properties individually such that they all match this special `texture-info`, and the colors property is specified as the keyword :default, then this `texture-info` will automatically be used internally.
