.SH "DESCRIPTION"
.PP
\fBglScissorArrayv\fR
defines rectangles, called scissor boxes, in window coordinates for each viewport\&.
\fIfirst\fR
specifies the index of the first scissor box to modify and
\fIcount\fR
specifies the number of scissor boxes to modify\&.
\fIfirst\fR
must be less than the value of
\fBGL_MAX_VIEWPORTS\fR, and
\fIfirst\fR
+
\fIcount\fR
must be less than or equal to the value of
\fBGL_MAX_VIEWPORTS\fR\&.
\fIv\fR
specifies the address of an array containing integers specifying the lower left corner of the scissor boxes, and the width and height of the scissor boxes, in that order\&.
.PP
To enable and disable the scissor test, call
\fBglEnable\fR()
and

\fBglDisable\fR
with argument
\fBGL_SCISSOR_TEST\fR\&. The test is initially disabled for all viewports\&. While the test is enabled, only pixels that lie within the scissor box can be modified by drawing commands\&. Window coordinates have integer values at the shared corners of frame buffer pixels\&.
glScissor(0,0,1,1)
allows modification of only the lower left pixel in the window, and
glScissor(0,0,0,0)
doesn\*(Aqt allow modification of any pixels in the window\&.
.PP
When the scissor test is disabled, it is as though the scissor box includes the entire window\&.
.SH "ERRORS"
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIfirst\fR
is greater than or equal to the value of
\fBGL_MAX_VIEWPORTS\fR\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if
\fIfirst\fR
+
\fIcount\fR
is greater than or equal to the value of
\fBGL_MAX_VIEWPORTS\fR\&.
.PP
\fBGL_INVALID_VALUE\fR
is generated if any width or height specified in the array
\fIv\fR
is negative\&.
