XpmCreateXpmImage(3) libXpm functions XpmCreateXpmImage(3) 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).
