The image to be masked for hardcopy output.
The output file, containing the masked image.
(starting line,starting sample,number of lines,number of samples)
starting line of the input image to be masked.
starting sample of the input image to be masked.
number of lines of the image to be included in the mask. If NL=0, all lines are used.
number of samples of the image to be included in the mask. If NS=0, all samples are used.
COMP specifies that the input image is to be complemented before masking. (Default is not to complement)
STRETCH=(N1,N2) specifies that a linear stretch will be applied to the input image before masking. Defaults are: for byte: N1=0, N2=255 for halfword: N1=0, N2=32767.
EXPAND=N specifies that all characters in the output will be 7*N lines by 6*N samples .VARIABLE ID This parameter controls the display of the account name and picture id. NOID specifies that id labels will not be displayed in the output. (Default is to display them)
LOGO specifies that the JPL Logo will be displayed to both sides of the IPL id labels. (Default is not to display the logo)
LLOGO specifies a left logo. Values for LLOGO and corresponding
logos are:
1 = JPL logo
2 = Mickey Mouse logo
3 = Goddard logo
4 = NASA logo
5 = ASTER logo
Default is that no logos are displayed
RLOGO specifies a left logo. Values for RLOGO and corresponding
logos are:
1 = JPL logo
2 = Mickey Mouse logo
3 = Goddard logo
4 = NASA logo
5 = ASTER logo
RLOGO is similar to keyword LLOGO except that this keyword
specifies a right logo. Default is that no logos are displayed.
If TASK is specified, MASKV searches for all occurrences of keyword 'TASK' in the VICAR history labels and then displays the values of 'TASK'.
If USER is specified, MASKV searches for all occurrences of keywords 'DATETIME' and 'USER' in the VICAR history labels and then displays all of their respective values.
If HISTORY is specified, then all VICAR history labels will be printed in the order in which they are found, excepting those with keywords 'TASK', 'USER', and 'DATETIME'.
If NOSYSTEM is specified the VICAR system label, containing the number of lines, number of samples, and data format, is not displayed with the masked imaged. The default is to display the system label.
