•
PNG: Portable Network Graphics, a common image format. PNG is a lossy compression format
that results in very small files. Files stored in PNG usually have a PNG extension.
•
Pseudocolor: Artificial application of color to a non-color (monochrome) image, or artificial re-
tinting of a colored image. LS Software provides several built-in pseudocolor sets that mimic
certain lighting conditions and reveal specific information in the image.
•
Resolution: The number of total pixels (width of the image in pixels multiplied by height of the
image in pixels). Higher resolution produces a smoother image (especially when zoomed in) but
requires more RAM and disk space.
•
TGA: Truevision Targa image format. TGA is a lossless compression format that reduces file size
somewhat. TGA files generally have a TGA extension.
•
Thumbnail: A reduced-size version of an image. From "thumbnail sketch."
•
TIFF: Tagged Image File Format, a common image format. Depending on settings, TIFF can be
either a lossy or a lossless compression format. In LS Software, it is used in the lossless mode to
reduce image file size without losing integrity. TIFF files generally have TIF or TIFF extensions.
•
Zoom Factor: The percentage by which the image is scaled. A zoom factor of 100% (1.0) means
that each pixel is not scaled; it is its original size. Zoom factors greater than 100% indicate that
the image has been scaled up (meaning that several screen pixels are used to show one actual
pixel). This generally makes detail easier to see. Zoom factors less than 100% mean that the
image has been scaled down. This makes it possible to see more of the image in the Image
window.
