Imports a cube from PNG, JPEG, JP2, BMP or TIFF format

History

Description

This program will import several standard image formats to an Isis cube. The input image formats may include PNG, JPEG, JP2, TIFF, BMP, and GIF. Not all formats are available as the program implementation depends on the Qt library by TrollTech. This is not true of JPEG2000 files (JP2). It has support in the ISIS library. By default, the number of bands in the output cube will be one, three, and four when the input image is all gray, RGB, and RGB with an alpha channel, respectively. The user can, however, specify the color mode manually. The JP2 file can have any number of bands up to 16384. The output from a JP2 file will be a multi-spectral ISIS image file.

Use this parameter to select the filename to import.

Description

Use this parameter to specify the name of the output cube.

Type cube
File Mode output
Pixel Type real

Color Model Options: MODE

Description

This parameter specifies the image mode for the output cube. If GRAYSCALE, a single one-band cube will be created. If RGB, a three-band cube is created. Finally, if ARGB is selected, then a four-band cube will be created where the four bands correspond to first Red, second Green, third Blue, and last Alpha.

Type string
Default AUTO
Option List:
Option Brief Description
AUTOAutomatically determine output mode Checks to see if the image is a grayscale image, and if not, if it has an alpha channel, and sets the output mode accordingly.
GRAYSCALEGrayscale mode A single-channel image.
RGBRGB mode A three-channel image (red, green, and blue).
ARGBARGB mode A four-channel image (red, green, blue, and alpha).

Special Pixels: SETNULLRANGE

Description

If this option is used input raw pixels below minimum and above maximum will be converted to LRS and HRS respectively. Otherwise pixels in the input raw file will be left unchanged in most cases. For example, importing a raw 8-bit file and outputing to a 16-bit or 32-bit real will cause 0 and 255 to be actual values. If left as 8-bit then 0 will be NULL and 255 will be HRS.

Examples

Example 1

Converting an image to an Isis Cube in Automatic mode

Description

This example will show the conversion from a color PNG image to a cube, automatically determining the color mode. Here, the output image will be a four-band ARGB cube, because the input image is both in color, and has an alpha channel.

Command Line

std2isis from=input.png to=argb.cub
Convert the PNG to an Isis Cube, with the default option of automatically determining the color mode

GUI Screenshot

Convert the image input.png to the Isis Cube argb.cub
Convert the image input.png to the Isis Cube argb.cub

Example GUI

Output Isis Cube with RGB

The same four-band ARGB output image viewed in color with RGB filtering (Band 1 = Red, Band 2 = Green, Band 3 = Blue). Note that the image here appears brighter than the original, because qview has auto-stretched the DN values, and can be adjusted back with qview's "stretch" tool. The actual data, however, has not been changed.

Output Isis Cube with RGA

The same four-band ARGB output image viewed in color with RGB filtering as in the previous image, but here Band 4 (the alpha channel) is viewed through the Blue filter.

Example 2

Converting an image to an Isis Cube in Grayscale mode

Description

This example will show the conversion from a color PNG image to a cube, with the color mode set to GRAYSCALE, meaning that the output image will be a single-band black-and-white cube.

Command Line

std2isis from=input.png to=gray.cub mode=grayscale
Convert the image input.png to the Isis Cube gray.cub. In order to get a single-band black-and-white image, we set the mode equal to GRAYSCALE.

GUI Screenshot

Converting an image to an Isis Cube in RGB mode

Description

This example will show the conversion from a color PNG image to a cube, with the color mode set to RGB, meaning that the output image will be a three-band color cube.

Command Line

std2isis from=input.png to=rgb.cub mode=rgb
Convert the image input.png to the Isis Cube rgb.cub. In order to get a three-band color image, we set the mode equal to RGB.
