imsize (1) Linux Manual Page
Name
imsize – Print size of image in WCS and pixels
Synopsis
imsize [-vcd] [-p scale] [-b ra dec] [-j ra dec] FITS or IRAF file(s)
Description
imsize is a utility for printing the region covered by an image using the world coordinate system parameters in IRAF and FITS image headers. It converts IRAF .imh image headers to a FITS format before extracting the information. For IRAF files, the image dimensions and the object name are set from the binary portion of the header.
Options
-b [<RA> <Dec>]- Output B1950 (B1950) coordinates (optional center)
-c- Format output without pixel dimensions (optional size change)
-d- Format output as input to DSS getimage (optional size change)
-e- Add epoch of image to output line
-j [<RA> <Dec>]- Output J2000 (J2000) coordinates (optional center)
-n <number>- Number of decimal places in output (default 3)
-p <scale>- Initial plate scale in arcsec per pixel (default 0)
-r- Print range in RA and Dec
-v- Print more intermediate information for debugging
-z- Use AIPS classic projections instead of WCSLIB
