XpmCreateImage(3) libXpm functions XpmCreateImage(3)
NAME XpmCreateImage - create an XImage from an XPM
SYNOPSIS
int XpmCreateImageFromData(Display *display, char **data, XImage **image_return, XImage **shapeimage_return, XpmAttributes *attributes);
int XpmCreateImageFromBuffer(Display *display, char *buffer, XImage **image_return, XImage **shapeimage_return, XpmAttributes *attributes);
int XpmCreateImageFromXpmImage(Display *display, XpmImage *image, XImage *image_return, XImage *shapeimage_return, XpmAttributes *attributes);

ARGUMENTS display Specifies the connection to the X server.
data Specifies the location of the data.
image_return Returns the image which is created.
shapeimage_return Returns the shape mask image which is created if the color None is used.
attributes Specifies the location of a structure to get and store information (or NULL).
shapeimage Specifies the shape mask image which is created if any.

DESCRIPTION XpmCreateImageFromData To create an XImage from an XPM data, use XpmCreateImageFromData().
The XpmCreateImageFromData() function allows you to include in your C program an XPM file which was written out by functions such as XpmWriteFileFromImage(3) or XpmWriteFileFromPixmap(3) without reading in the file. XpmCreateImageFromData() exactly works as XpmReadFileToImage(3) does and returns the same way. It just reads data instead of a file. Here again, it is the caller's responsibility to free the returned images, the colors and possibly the data returned into the XpmAttributes structure.

XpmCreateImageFromBuffer To create an XImage from an XPM buffer, use XpmCreateImageFromBuffer(). The XpmCreateImageFromBuffer() function works the same way as XpmReadFileToImage(3), it just parses the buffer instead of the file. From the given XpmImage and XpmAttributes if not NULL, XpmCreateImageFromXpmImage() allocates colors and creates X images following the same mechanism as XpmReadFileToImage(3). When finished the caller must free the images using XDestroyImage(3), the colors using XFreeColors(3), and possibly the data returned into the XpmAttributes using XpmFreeAttributes(3).
