If the input data +are of type image, the array is generated by extracting the specified +image rows and then binning them according to the specified bin +factor. If the input data are contained in a binary table or raw +event file, the rows are binned on the columns specified by the +\&\fBbincols=\fR keyword (using appropriate default columns as needed), +after which the image section and bin factors are applied. +.PP +The first argument is the Funtools handle returned by +\&\fIFunOpen()\fR. The second \fBbuf\fR +argument is a pointer to a data buffer to fill. If \s-1NULL\s0 is specified, +\&\fIFunImageGet()\fR will allocate a buffer of the appropriate size. +.PP +The third and fourth arguments specify the first and last row to +retrieve. Rows are counted starting from 1, up to the value of +\&\s-1FUN_YMAX\s0(fun). The final \fBplist\fR (i.e., parameter list) argument +is a string containing one or more comma-delimited +\&\fBkeyword=value\fR parameters. It can be used to specify the return +data type using the \fBbitpix=\fR keyword. If no such keyword is +specified in the plist string, the data type of the image is the same +as the data type of the original input file, or is of type int for +\&\s-1FITS\s0 binary tables. +.PP +If the \fBbitpix=\fRvalue is supplied in the plist string, the data +type of the returned image will be one of the supported \s-1FITS\s0 image +data types: +.IP "\(bu" 4 +8 unsigned char +.IP "\(bu" 4 +16 short +.IP "\(bu" 4 +32 int +.IP "\(bu" 4 +\&\-32 float +.IP "\(bu" 4 +\&\-64 double +.PP +For example: +.PP +.Vb 17 +\& double *drow; +\& Fun fun; +\& ... open files ... +\& /* get section dimensions */ +\& FunInfoGet(fun, FUN_SECT_DIM1, &dim1, FUN_SECT_DIM2, &dim2, 0); +\& /* allocate one line's worth */ +\& drow = malloc(dim1*sizeof(double)); +\& /* retrieve and process each input row (starting at 1) */ +\& for(i=1; i <= dim2; i++){ +\& if( !FunImageRowGet(fun, drow, i, i, "bitpix=-64") ) +\& gerror(stderr, "can't FunImageRowGet: %d %s\en", i, iname); +\& /* reverse the line */ +\& for(j=1; j<=dim1; j++){ +\& ... process drow[j-1] ... +\& } +\& } +\& ... +.Ve +.PP +On success, a pointer to the image buffer is returned.
