The NOMSSI Viewer
This program allows you to read pictures archived in files with different image file
formats. It requires a SuperVGA card in your PC to display the picture. The pictures may also be writen to files using the TIFF format.
Use the dialogbox "Load an image file" to load and display a picture. To open this box press F3 or click on the item 'F3 Load' in the statusline.
The NOMSSI Viewer can be customized using the setup dialogbox. Press F9 to open this window. All default values and miscellaneous switches can be set and saved there. )

The list window shows all files in the current directory which meet the file mask in the input

To position the cursor on a file use the arrow keys, the Home/End keys,the Ctrl + PgUp/PgDn keys, or perform incremental search: type small letters for files and capital letters for directories. The cursor jumps to the next file matching your input. Backspace go back.
Pressing Enter or Alt
L initiates an image display or a directory change, if the focused item was a directory. Changing to the upper directory sets the cursor at the name of the previously selected directory. &
While using a mouse, double click on a choosen file name to load and display an image. Alternative click on the Load-button to load the actually selected (highlighten) file. To select a file, click once on it with the left mouse button. Use the horizontal scrollbar to move through the files.
The space bar or the right mouse button tag a file. Tagging files is useful for Slideshow or file management operations (copying, moving, delete), which are only allowed while the file list is focused.

To force a re-read of the current directory (i.e. after changing the disk from a floppy drive), either enter a new file mask in the input

Contrast
While viewing a picture, you can change its contrast (see: graphic
tools). To accurately reproduce color picture from different devices, especially to display scanned pictures, it must be taken into consideration that monitors have nonlinear output curves. Device-dependent color correction curves are used to map the color values.
One generally uses exponential curves, which are analytically described with an exponent "gamma". You may set a monitor "Gamma" here, that will be used to correct your picture color values. H
( ) linear
This should be your standard, it means no correction of the color intensity. It will work well with all computer-generated pictures and most of the others, which are already corrected for monitor output. H
( ) Monitor
This option is for scanned color images advisable. Gamma = 2,2 is for monitor output quite a good value. H
( ) user defined
This option enables you to select the Gamma inputline. You can input a gamma value in the range from 0.1 to 7 now. ;

Normally, the native VGA chipset in your machine is autodetected and The NOMSSI Viewer works with chipset-dependent code. Choosing this option, you force the use of the VESA interface, which is chipset-independent and enhances compatibility.
Having a video card that has a VESA compatible BIOS, or installing a TSR program that provides Video BIOS extensions (like the universal VESA VBE) will make The NOMSSI Viewer work correctly with your SuperVGA. I
The NOMSSI Viewer detects and uses the available VESA 256 colors modes. J
You may already have a VESA TSR for your video card, check your drivers disk for it.

SVGA
SVGA (SuperVGA) is a graphic card standard for PCs, that electronically take control of the screen output in graphic modes with a resolution of at least 640x480 pixels with 256 simultaneous colors.
A SVGA card converts the digital color values in analog voltage to control analog monitors using a digital-analog-converter (DAC). A normal DAC includes 256 registers, each subdivided in three groups of 6 bits (for the colors red, gree, blue). thus there are max. 64 gradations for a priming and altogether possible 262144 colors. However only 256 colors can be displayed at a time (HiColor and TrueColor DACs allow more colors). |
The NOMSSI Viewer supports only the 256 color modes for a variety of SVGA cards (using VGADOC (c) 1993 by Finn Th
gersen).

Raster image data
Bi-level images contains two colors - black and white. Grayscale images store shades of gray for each pixel and have one component per pixel. Color pictures are usualy described using the RGB model. Each pixel is made up of three components (red, green and blue). In the RGB full color case, each component is 8 bit deep. Palette color images still have one component per image, but the component value is used as an index into a full RGB lookup table. -
