图 15.96. The XBM Export dialog

X BitMap (XBM), is a plain text image format that was mainly used for cursors and icon bitmaps in the X GUI. This format was superseded by X PixMap.

This format only supports exporting as black and white monochrome images. GIMP only supports exporting to this from 8-bits per channel images.

Due to being stored in the form of C source files, this format can take up more space than other binary formats.

#### 5.55.2. Options

X10 format bitmap

  When checked, the image will use short integers instead of bytes to write the data.

Identifier prefix

  The prefix used to write the data. This is mainly useful if you intend to read this file from C source code.

Write comment

  When checked, a comment will be added to the output file. Not all image viewers are able to correctly show this image if a comment is present.

注释

  When the above setting is enabled, you can enter your comment here.

Write hot spot values

  When checked, hot spot values will be added. These are used in icon files to set the location of the icon hot spot.

Hot spot X, Hot spot Y

  These values set the X and Y coordinate of the hot spot of the mouse cursor.

Write extra mask file

  When checked, a separate mask file will be created. The mask file contains the alpha channel for the XBM image. This setting is only enabled when your image has an alpha channel.

Mask file extensions

  This allows you to set the suffix that will be added to the name of your image. The name with suffix will be used to write the mask file.
