.SH DESCRIPTION
.SS XpmWriteFileFromImage
The XpmWriteFileFromImage function writes an image and its possible shapeimage out to a file in the XPM format.
If the file cannot be opened, it returns XpmOpenFailed.
If insufficient working storage is allocated, it returns XpmNoMemory.
If no error occurs then it returns XpmSuccess.
If the passed XpmAttributes structure pointer is not NULL,
XpmWriteFileFromImage looks for the following attributes:
XpmColormap, XpmHotspot, XpmCharsPerPixel, XpmRgbFilename, and XpmExtensions.
As a backward compatibility feature, XpmWriteFileFromImage also looks for the XpmInfos attributes.
If the filename contains an extension such as “.xpm”, in order to get a valid C variable name, the dot character is
replaced by an underscore ’_’ when writing out.
As a backward compatibility feature, if the XpmInfos attributes are defined it writes out possible stored
information such as comments, color defaults and symbol.
Finally, if the XpmRgbFilenameattribute is defined, XpmWriteFileFromImage searches for color names in
this file and if found writes them out instead of the rgb values.
In addition on systems which support such features if the given file name ends by ’.Z’ or ’.gz’
it is assumed to be a compressed file. Then, XpmWriteFileFromImage writes to a piped compress or gzip process.
And if instead of a file name NULL is passed to XpmWriteFileFromImage, it writes to the standard output.
.SS XpmWriteFileFromPixmap
To write out a Pixmap to an XPM file, use XpmWriteFileFromPixmap.
If the passed XpmAttributes structure pointer is not NULL,
XpmWriteFileFromPixmap looks for the following attributes: XpmSize.
If they are not defined it performs an XGetGeometry operation.
Then it uses XGetImage to get from the given pixmaps the related X images which are passed to XpmWriteFileFromImage.
Finally XpmWriteFileFromPixmap destroys the created images using XDestroyImage.
The XpmWriteFileFromPixmap function returns the same errors as XpmWriteFileFromImage.
.SS XpmWriteFileFromData
XpmWriteFileFromData writes an XPM data array to an XPM file.
XpmWriteFileToData returns XpmOpenFailed if it cannot open the file,
XpmFileInvalid if this is not a valid XPM data, and XpmSuccess otherwise.
.SS XpmWriteFileFromXpmImage
To write out an XpmImage to an XPM file, use XpmWriteFileFromXpmImage.
The XpmWriteFileFromXpmImage function writes an image out to a file in the XPM format.
If the file cannot be opened, it returns XpmOpenFailed.
If insufficient working storage is allocated, it returns XpmNoMemory.
If no error occurs then it returns XpmSuccess.
If the passed XpmInfo structure pointer is not NULL, XpmWriteFileFromXpmImage looks for the following attributes:
XpmComments, XpmExtensions, and XpmHotspot, and writes the related information out as well.
In addition on systems which support such features if the given file name ends by ’.Z’ or ’.gz’ it is assumed to be a
compressed file. Then, XpmWriteFileFromXpmImage writes to a piped compress or gzip process. And if instead
of a file name NULL is passed to XpmWriteFileFromXpmImage, it writes to the standard output.
.SS XpmWriteFileFromBuffer
XpmWriteFileFromBuffer writes a XPM buffer to a file.
XpmWriteFileFromBuffer returns XpmOpenFailed if it cannot open the file, and XpmSuccess otherwise.
As a convenience, the XpmReadFileToBuffer and XpmWriteFileFromBuffer functions
are provided to copy a file to a buffer and to write a file from a buffer.
Thus for instance one may decide to use XpmCreateBufferFromPixmap,
XpmWriteFileFromBuffer, and XpmFree instead of XpmWriteFileFromPixmap.
On some systems this may lead to a performance improvement,
since the parsing will be performed in memory, but it uses more memory.
