MSP_display

(ANSI C programs)

The display programs were moved to the DISP package.

INTRODUCTION
There are two main approaches to display the various image data:
1. To use one of the display programs (names start with dis) to directly display the data directly on the screen using the XView toolkit libraries.
2. To first use one of the programs to generate a SUN raster or BMP format image (names start with ras), and then to display the image using an external viewer such as xv or disrasz.

MSP display tools

dis2SLC Display magnitude of two complex data sets and rapidly switch display
disbyte Display byte data
dismph Display magnitude and phase of complex data (float)
dismph_fft64 Display magnitude of complex data (float) and fft for cursor location
dismph_ub Display magnitude and phase of complex data (IQ unsigned byte)
dispwr Display magnitude of real data (float)
disrasz Display image data in SUN raster or BMP format images (8-bit)


MSP tools to generate SUN raster or BMP format images

There are additional notes on the programs

rasSLC Magnitude of complex SAR data (float)
rasbyte Signed byte data
rasmph Interferometric phase/interferometric correlation
raspwr Backscatter intensity (power law scaling)


Display Programs

All input data that have floating point have the data stored in single-precision (32 bits) representation. Complex values and slope data are stored as pairs of single-precision (32-bit) numbers. Intensity, correlation, heights, and phase are all stored as single-precision floating point numbers unless otherwise noted.

Program Input Parameter(s) Color Brightness
disbyte signed byte data none value
 disSLC floating point complex data none value
dismph complex data (interferograms) phase magnitude
dismph_ub complex as pairs unsigned byte data (IQ raw data) phase magnitude
dispwr intensity none value (power-law scale)
disrasz SUN raster and BMP format images image lookup table image lookup table
