Description

Save data to a file

Arguments and Return Values

Arguments: A data object, a filename and a file type.

Return Value: None. A file is written.

Usage

Syntax: save(object=VAL, filename="path", type=TYPE, force=1)

The save() function copies data to a file. The value of type specifies the type of file written, and is one of:

specpr - SpecPR vicar - Vicar grayscale grd - USGS Grid pgm - Pbmplus 8-bit grayscale ppm - Pbmplus 24-bit true-color isis - PDS/ISIS ascii - Columnar ascii matrix imath - Imath format ers - ER Mapper Raster gif - Compuserve GIF format tiff - Tagged Image File Format jpeg - Joint Photographic Experts Group png - Portable Network Graphics bmp - Microsoft Bitmap raw - Binary output, no header

If the force keyword is included, then any existing file of the same name is overwritten. Without this keyword, the write is aborted if the filename already exists.

Notes:

The standard graphics formats (GIF, TIFF, JPEG, PNG, BMP, PPM), all expect either 1 or 3 band, byte images. A 3-band image is interpreted to be a red band, a green band and a blue band.

The PGM and GRD formats can not handle multiplane data.

The ERS format produces two files, one named "path", containing the raw raster data, and another named "path.ers", containing the ERS header. This is the standard for ERS files.

save() is an alias for write().

Examples

dv> a
100x100x1 array of float, bsq format [40,000 bytes]

dv> save(a,"test.cub",vicar,force=1)
