NAME
XpmCreateXpmImage - create an Xpm image
SYNOPSIS
int XpmCreateXpmImageFromData(char **data, XpmImage *image,
XpmInfo *info);
int XpmCreateXpmImageFromBuffer(char *buffer, XpmImage *image,
XpmInfo *info);
int XpmCreateXpmImageFromImage(Display *display,
XImage *image, XImage *shapeimage,
XpmImage *xpmimage, XpmAttributes *attributes);
int XpmCreateXpmImageFromPixmap(Display *display,
Pixmap *pixmap, Pixmap *shapemask,
XpmImage *xpmimage, XpmAttributes *attributes);
ARGUMENTS
data Specifies the location of the data.
image Specifies the image structure location.
info Specifies the location of an XpmInfo structure to get and store
information (or NULL).
display
Specifies the connection to the X server.
image Specifies the X image used as the source.
shapeimage
Specifies the shape mask image, if any.
xpmimage
Specifies the XPM image which is created.
attributes
Specifies the location of a structure containing information (or
NULL).
DESCRIPTION
XpmCreateXpmImageFromBuffer
To create an XpmImage from an XPM buffer, use XpmCreateXpmImageFrom-
Buffer(). The XpmCreateXpmImageFromBuffer() function 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. On success it
returns XpmSuccess. 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 XpmRe-
turnExtensions 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.
XpmCreateXpmImageFromData
To create an XpmImage from an XPM data, use XpmCreateXpmImageFrom-
Data(). XpmCreateXpmImageFromData() fills in the given XpmImage struc-
ture from the given data. If the data does not contain valid XPM data,
it returns XpmFileInvalid. If insufficient working storage is allo-
cated, it returns XpmNoMemory. On success it returns XpmSuccess. If
the passed XpmInfo structure pointer is not NULL, XpmCreateXpmImage-
FromData() 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 XpmReturnEx-
tensions cannot be returned as requested because of insufficient memory
storage, XpmCreateXpmImageFromData() will change the valuemask to men-
tion 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.
XpmCreateXpmImageFromImage
To create an XpmImage from an XImage, use XpmCreateXpmImageFromImage().
From the given X images and XpmAttributes if not NULL, XpmCreateXpmIm-
ageFromImage() creates an XpmImage following the same mechanism as
XpmWriteFileFromImage(3).
XpmCreateXpmImageFromPixmap
To create an XpmImage from a Pixmap, use XpmCreateXpmImageFromPixmap().
From the given pixmaps and XpmAttributes if not NULL, XpmCreateXpmIm-
ageFromPixmap() 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 us-
ing XDestroyImage(3).
