.SH SYNOPSIS

Specifies the location of an XpmInfo structure to get and store information (or NULL).
.IP \fIdisplay\fP li
Specifies the connection to the X server.
.IP \fIimage\fP li
Specifies the image which is created.
.IP \fIshapeimage\fP li
Specifies the shape mask image which is created if any.
.IP \fIxpmimage\fP li
Specifies the location of an XpmImage structure.
.IP \fIattributes\fP li
Specifies the location of a structure containing information (or NULL).
.SH DESCRIPTION
.SS XpmCreateXpmImageFromBuffer
To create an XpmImage from an XPM buffer, use XpmCreateXpmImageFromBuffer.
The XpmCreateXpmImageFromBuffer reads the given buffer to fill in the given XpmImage structure.
If the buffer does not contain valid XPM data, it returns XpmFileInvalid.
If insufficient working storage is allocated, it returns XpmNoMemory, and returns XpmSuccess on success.
If the passed XpmInfo structure pointer is not NULL, XpmCreateXpmImageFromBuffer looks for the following attributes:
XpmReturnComments and XpmReturnExtensions, and sets possibly the XpmHotspot attribute when returning.
As specified in the table (page 28), if the data related to the attributes XpmReturnComments and
XpmReturnExtensions cannot be returned as requested because of insufficient memory storage,
XpmCreateXpmImageFromBuffer will change the valuemask to mention this and will try to continue.
So the caller should check on this before accessing requested data.
Note: The valuemask of the passed XpmInfo structure must be set to some valid value,
at least zero, otherwise unpredictable errors can occur.
.SS XpmCreateXpmImageFromData
To create an XpmImage from an XPM data, use XpmCreateXpmImageFromData.
XpmCreateXpmImageFromData fills in the given XpmImage structure from the given data. If the data does not
contain validXPM data, it returnsXpmFileInvalid. If insufficient working storage is allocated, it returns
XpmNoMemory, on success it returns XpmSuccess.
If the passed XpmInfo structure pointer is not NULL, XpmCreateXpmImageFromData looks for the following attributes:
XpmReturnExtensions, and sets possibly the XpmHotspot attribute when returning.
As specified in the table (page 28), if the data related to the attribute
XpmReturnExtensions cannot be returned as requested because of
insufficient memory storage,XpmCreateXpmImageFromData will change the valuemask to mention this and will
try to continue.
So the caller should check on this before accessing requested data.
Note: The valuemask of the passed XpmInfo structure must be set to some valid value, at least zero,
otherwise unpredictable errors can occur.
.SS XpmCreateXpmImageFromImage
To create an XpmImage from an XImage, use XpmCreateXpmImageFromImage.
From the given X images and XpmAttributes if not NULL, XpmCreateXpmImageFromImage creates an
XpmImage following the same mechanism as XpmWriteFileFromImage.
.SS XpmCreateXpmImageFromPixmap
To create an XpmImage from a Pixmap, use XpmCreateXpmImageFromPixmap.
From the given pixmaps and XpmAttributes if not NULL, XpmCreateXpmImageFromPixmap gets the related Ximages
by calling XGetImage, then it gives them to XpmCreateXpmImageFromImage() to create an
XpmImage which is returned to xpmimage.
Finally it destroys the created X images using XDestroyImage.
