The type real procedures may be +applied to images of either type, but the type short procedures may only +be used to access images of type short. The output buffer should contain +at least (i1-i2+1) pixels (\fIps1\fR), ((j2-j1+1) * (i2-i1+1)) pixels +(\fIps2\fR), or ((k2-k1+1) * (j2-j1+1) * (i2-i1+1)) pixels (\fIps3\fR). +The pixels are assumed to be in Fortran storage order. The column index +\fIi2\fR must be greater than or equal to \fIi1\fR, but the remaining +subscripts may be swapped if desired. +.ih +RETURN VALUE +A zero status is returned if the referenced image line is in-bounds and +the actual pixel datatype of the image is one of the types permitted by +the particular operator called. + +.nf +IE_NOTSHORT: imfort short integer i/o requires a type short image +IE_PIXTYPE: image pixel type must be short or real +IE_WRPIX: error writing image pixel file +IE_XOOB: image x coordinates out of range or out of order +IE_YOOB: image y coordinates out of range +IE_ZOOB: image z coordinates out of range +.fi +.ih +SEE ALSO +imgs, imgl, impl +.endhelp |
