|
|
The port id of a port on an XvImage capable adaptor.
|
||
|
|
.IP \fId - The target drawable.
|
||
|
|
.IP \fIgc\fR 8

.SH DESCRIPTION
|
||
|
|
.BR XvPutImage (__libmansuffix__)
|
||
|
|
is similar to
|
||
|
|
.BR XPutImage (__libmansuffix__).
|
||
|
|
.BR XvShmPutImage (__libmansuffix__)
|
||
|
|
is similar to
|
||
|
|
.BR XShmPutImage (__libmansuffix__).
|
||
|
|
The library will allocate the XvImage structure and fill out all
|
||
|
|
fields except for \fIdata\fR. \fIWidth\fR and \fIheight\fR may be
|
||
|
|
enlarged in some YUV formats. The size of the data buffer that needs
|
||
|
|
to be allocated will be given in the \fIdata_size\fR field in the XvImage.
|
||
|
|
Image data is not allocated by this function. The client may pass a pointer
|
||
|
|
to the preallocated memory as \fIdata\fR or may allocate the memory and fill in
|
||
|
|
the XvImage structure's data field after the \fIdata_size\fR field has
|
||
|
|
been filled out by the server. The XvImage structure may be freed by
|
||
|
|
.BR XFree (__libmansuffix__).
|
||
|
|
.SH DIAGNOSTICS
|
||
|
|
.IP [XvBadPort] 8
|
||
|
|
Generated if the requested port does not exist.
|
||
|
|
.IP [XvBadAlloc] 8
|
||
|
|
Generated if the X server was unable to allocate resources required
|
||
|
|
to complete the operation.
|
||
|
|
.IP [BadMatch] 8
|
||
|
|
Generated if incompatible arguments were supplied, such as a port that
|
||
|
|
isn't capable of displaying XvImages.
|
||
|
|
.IP [BadShmSegCode] 8
|
||
|
|
Generated if an invalid shared memory segment is specified.
