XpmCreateBuffer(3) libXpm functions XpmCreateBuffer(3) NAME XpmCreateBuffer - create an XPM Buffer SYNOPSIS int XpmCreateBufferFromImage(Display *display , char **buffer_return, XImage *image, XImage *shapeimage, XpmAttributes *attributes); int XpmCreateBufferFromPixmap(Display *display, char **buffer_return, Pixmap pixmap, Pixmap shapemask, XpmAttributes *attributes); int XpmCreateBufferFromXpmImage(char **buffer_return, XpmImage *image, XpmInfo *info); ARGUMENTS display Specifies the connection to the X server. buffer_return Returns the buffer which is created. image Specifies the image. shapeimage Specifies the shape mask image. attributes Specifies the location of a structure containing information (or NULL). info Specifies the location of a structure to get possible informa- tion (or NULL). DESCRIPTION XpmCreateBufferFromPixmap XpmCreateBufferFromPixmap() creates an XPM buffer from a Pixmap. The XpmCreateBufferFromPixmap() function works as XpmWriteFile- FromPixmap(3), it just calls XpmCreateBufferFromImage() instead of XpmWriteFileFromImage(3). Once again, the caller should free the buffer using XpmFree(3) when finished. As a convenience, the XpmReadFileToBuffer(3) and XpmWriteFileFrom- Buffer(3) 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(3), and XpmFree(3) instead of XpmWriteFileFromPixmap(3). On some systems this may lead to a performance improvement, since the processing will be performed in memory, but it uses more memory. XpmCreateBufferFromImage The XpmCreateBufferFromImage() function works as XpmWriteFileFromIm- age(3), it just writes to a malloced buffer instead of to a file. The caller should free the buffer using XpmFree(3) when finished. XpmCreateBufferFromXpmImage. To create an XPM buffer from an XpmImage, use XpmCreateBufferFromXpmIm- age(). The XpmCreateBufferFromXpmImage() function writes out the given image to a single block malloced buffer in XPM format. If insufficient working storage is allocated, it returns XpmNoMemory, and returns Xpm- Success on success. If the passed XpmInfo structure pointer is not NULL, XpmCreateBufferFromXpmImage() looks for the following attributes: XpmComments, XpmExtensions, and XpmHotspot, and writes the related in- formation out as well. The caller should free the buffer using Xpm- Free(3) when finished.
