What is the .HST File Extension?

.HST File Extension Description:

the Image Alchemy program utilizes the file extension .hst, which is part of the product line of Handmade Software. The file extension .hst is identified as the HSI raw file belonging to the image files of the program, which represents an interchange for generic bitmaps. The program associated with the file extension .hst, is classified under the image processing software with format conversion capabilities that allows it to manipulate various images either by importing them to the native format, or exporting it to other popular image types. The Image Alchemy program was initially designed for UNIX, but was subsequently ported to the MS-DOS environment.

The file extension .hst has the ability to save either an 8- or a 24-bit image (bitmap) data representing those that have 256 colors or less, and those that are categorized as true color data respectively. The HSI Raw format associated with the file extension .hst currently supports both versions 4 and 5, which are almost similar except that the latest version has added capability for handling pixels on the alpha channel including support for image (compressed) data. The file extension .hst associated with the HSI Raw, is not synonymous with the BIF format created by the program for binary data.

In essence, the file extension .hst can be divided into two classifications, one that supports anywhere from two to a maximum of 256 colors utilizing a color palette placed next to the header, prior to the data of the image. The second class is one, which supports RGB that utilizes pixels in place of palette, and saved under a single file. The file extension .hst is capable of saving gray-scale, bi-level and true color graphics, which has no padding to allow alignment of the boundary bytes.

Another common implementation of the file extension .hst is as a history file for various applications running under the Microsoft Windows Operating System platform like Internet Explorer, Messenger Service, and the likes. The .hst file extension in this context saves relevant information on the settings, and how the user applies the particular program.
