Saving Enhanced (scaled) Images

Why File / Save Image as ... won't work.

Lispix represents its images like this:

More explanations of this diagram.

Gray level images that have been enhanced using the Scale Menu or the Colorize Menu still retain their original data.  When these images are saved, it is the original data that is saved, not the scaled 8 bit version, and not the pixmap, which may have had false color applied to it.


Saving Gray Scale Images

The Scale menu, and the Contrast, Dimmer, Directional and Gamma Colorizer Sliders result in gray scale enhanced images.

If the enhanced image is a gray scale image, or if you wish to discard the color information and save it as a gray scale image, then use

Image / Convert to 8-Bit Gray Level

and save the new image as a TIFF or JPEG file.

The new image should look like the enhanced one.  The difference is that the 'original' data of the new image is what you see - the new image is linearly scaled and has the default color look up table.


Saving Color Images

Eight-bit gray level images with false color can be saved directly as TIFF files.  Sixteen-bit gray level images with false color can also be saved in this way - Lispix will give you the option of whether to save the sixteen bit data or save the 8-bit scaled data with the color table.  RGB images can be saved directly as TIFF or JPEG, since each color plane is 8-bits deep.

To save a gray scale version of a color enhanced image, such as made with the Multi-color slider or the Thermal slider, just use Image / Convert to 8-Bit Gray Level and save the new image as a TIFF or JPEG file.

Images with graphics are saved using <ctrl>-Print Screen or <alt>-Print Screen, which copies a screen image to the clipboard.  You can then paste the image into another program such as Photoshop* or Word* and save it using that program.
