DPARM (1,2) pixrange for hue image ---------------------------------------------------------------- HUINT Type: Task Use: HUINT will construct a TV image based on two AIPS images, one representing intensity and one representing hue. The task attempts to replicate the function of the verb TVHUEINT but with the possibility to save the result as a rather peculiar image. The program enters an interactive mode in which the user selects options from a menu shown on a graphics overlay plane. Options are to enhance each of the images individually, to select linear, square-root, or one of 2 logarithmic transfer functions for intensity or hue, and to exit with or without final updates and an output file. On-line help for the options is available by positioning the cursor to the option and pushing button D. Pushing buttons A, B, or C selects the option. Unlike TVHUI, this task works only on TVs capable of supporting the TVHUEINT verb. The XAS TV does this as did some hardware TVs of old. Adverbs: INNAME......Image name for intensity. Standard defaults. INCLASS.....Image class for intensity. Standard defaults. INSEQ.......Image seq. # for intensity. 0 => highest. INDISK......Disk unit # for intensity. 0 => any. IN2NAME.....Image name for hue. Standard defaults. IN2CLASS....Image class for hue. Standard defaults. IN2SEQ......Image seq. # for hue. 0 => highest. IN2DISK.....Disk unit # for hue. 0 => any. DOOUTPUT....> 0 => write an output image with the 3rd axis being RGB. The full range of input intensities is NOT carried along (i.e. PIXRANGE is applied and the actual numbers will be in the range 0 - 1.). The display intensity transfer function is used as well as the scaling, clipping and transfer function of the hue image done from DPARM(1 -> 2) plus any interactive enhancement. >= 2 => also write an image of the hue-intensity step wedge. 2 causes the hue to be on the (usually short) vertical axis with intensity on the (usually longer) horizontal axis, 3 reverses this. <= 0 -> skip output file. OUTNAME.....Output name for RGB cube. Standard defaults. OUTCLASS....Output class for RGB cube. Standard defaults. OUTSEQ......Output seq. # for RGB cube. 0 => highest unique OUTDISK.....Disk drive # of RGB cube. 0 => highest with space. OUT2NAME....Output name for RGB wedge. Standard defaults. OUT2CLAS....Output class for RGB wedge. Standard defaults. OUT2SEQ.....Output seq. # for RGB wedge. 0 => highest unique OUT2DISK....Disk drive # of RGB wedge. 0 => highest with space. IMSIZE......Controls the X and Y sizes in pixels of the output wedge image which is written when DOOUTPUT = 2 or 3. IMSIZE(1) < 25 -> TTRC(1)-TBLC(1)+1 or the maximum TV X size if that is less. IMSIZE(2) < 20 -> 0.2 * Max (IMSIZE(1), 100) TBLC........Bottom Left Corner of intensity image used in the display. (0,0) means (1,1). The hue image window is the same size as the intensity image window, but a smaller window will be selected if needed to overlap the images. See DOALIGN. The image size is also limited by the size of the TV. TBLC is ignored on writing the output image except for any alignment adjustments. TTRC........Top Right Corner of grey-scale image: (0,0) means top right corner of map. NOTE: for the intensity image TTRC(3-7) is set to TBLC(3-7) since only one plane is shown. If the hue image is a cube, TTRC(3) is taken to select the plane of that cube to be used for hue. This allows a hue image of one plane to color am intensity image of another plane of the same cube. TTRC is ignored on writing the output image except for any alignment adjustments. TXINC.......Increment in pixels between displayed pixels along the X axis. 0 => 1. Ignored while doing output. TYINC.......Increment in pixels between displayed pixels along the X axis. 0 => 1. Ignored while doing output. DOALIGN.....Controls how the intensity, hue, and saturation images are to be aligned (see HELP DOALIGN). True (>.1) means that the images must agree in their coordinates, though not necessarily in the reference pixel position. Alignment is by coordinate values (if DOALIGN > -0.1) or by offsets from the reference pixel positions (if DOALIGN <= -0.1). If DOALIGN < -1.5, alignment is at pixels (1,1,...) ignoring the headers. TVCHAN......TV channel to use: 0 => 1. Two channels are used, one for the intensity image and one for the hue image. Unlike TVHUEINT, the option to switch roles of the images is NOT offerred. DOWEDGE.....If false (<= 0.0), do not plot a step wedge. Otherwise plot a wedge on the TV, but not in the output image. (A wedge image is written if DOOUTPUT = 2 or 3.) If 1.5 >= DOWEDGE > 0.0, then plot a wedge along the top of the image. If > 1.5, plot a wedge along the right-hand edge of the image. If > 2.5, plot wedges along both the top and the right-hand side. Each wedge is a wedge in intensity along the longer side of the wedge and in hue along the shorter side of the wedge. Multiple wedges are drawn for each saturation level. DOCIRCLE....False (<= 0) means that colors range from red to green to blue only. This is appropriate for 0th and 1st moment images for example. True means that colors range from red to green to blue and back to red (through purple). This is appropriate to polarization intensity and angle images, for example. PIXRANGE....Min,Max of Image intensity. 0 => entire range DPARM.......(1,2) pixrange for HUE image. 0,0 => full range ----------------------------------------------------------------
