SnagIt - Version 1.5
"SnagIt" is a Microsoft Windows 3.0 screen capture and screen print
utility. Theoretically it should work with other Win30 BitBlt-able
printer drivers.
"SnagIt" gathers a 'region' of the screen and sends it to 'output'
with either color, monochrome, or simulated grayscale.
"SnagIt" Term definitions
I. Device:
The device is the screen shot destination. Currently "SnagIt"
only sends its output to either the Clipboard or the currently
selected printer. Printer selection is be changed with the
Control panel.
II. Region:
"SnagIt" knows about three types of areas, or regions, on the
screen. If the current region is the SCREEN then the entire
screen from the upper left corner to the lower right corner is
sent to the selected device.
The Windows screen is composed of small "windows". A window may
be bounded with a border and scroll bars or it may be just and
icon. By definition the CLIENT region is the area within a
window bounded by the border but not including scroll bars or
the caption line.
A REGION is the area inside the rectangle drawn when the left
mouse button is held down starting where the button was pushed.
When the mouse button is let up "SnagIt" will capture the
region.
Examples:
a) CLIENT is selected as the region and the mouse pointer is
clicked on an icon only the icon will be captured.
b) If the client area of a program's window is desired, CLIENT
must be selected and the mouse pointer should point to that
window's caption bar.
c) WINDOW is selected as the region and the mouse pointer is
clicked on a window the entire window including the caption
bar, border, and scroll bars will be captured.
d) REGION is selected and the mouse is in the upper left corner
of the screen. Pressing the left button and dragging the
mouse to the middle of the screen then releasing the button
will capture the upper left quarter of the screen.
III.Scaling:
Scaling only applies when device = printer.
Scaling option explanations:
1) Best fit expands the 'region' to fill the output page.
2) Screen fit scales the 'region' as though the entire screen
was being printed as best fit. All printouts will have the
same scale.
3) User specified ratio. The user specified ratio is the ratio
of printer pixels to screen pixels. The value must be an
integer greater or equal to 1. The ratio value will be
readjusted if it is too large to fit the image on the paper.
For VGA and a standard 300 dpi printer the ratio is 3. Must
be entered at runtime.
IV. Output:
Output is how the image is to appear on the device. Generally
it is a good idea to send a monochrome image to a monochrome
device. For example the standard Windows 3.0 driver for the HP
LaserJet II will take color output but is no different than mono
output but the standard PostScript driver must have monochrome
output because it ignores color.
Windows normally converts a color bitmap (the screen) to a
MONOCHROME bitmap by setting every pixel black that is not the
background color. For some selected screen color combinations
will have a lot of black. For example the gray 3D push buttons
at the upper right of of a window may be all black.
As an option MONOCHROME intensity output may be adjusted by a
percentage. A monochrome percentage of 100% is the same as the
normal windows conversion. An intensity percentage of 50%
checks each pixel's intensity. If the intensity is greater than
or equal to 50% then the pixel is white.
Where more color information is required the GRAY SCALE option
will dither color intensity to 256 levels of gray. Each color
may be enhanced or reduced by adjusting the color intensities.
Gray scaling the output is very slow. A good idea it to
experiment with a small region before commiting the entire
screen. Remember that boosting the color increases the
intensity which lightens the output.
The COLOR option just sends the image to the device without any
modifications or enhancements.
"SnagIt" configurations may be set in the 'win.ini' file. The
following table lists the key word and the options.
+------------------------------------------------------------+

+------------------------------------------------------------+
Add a '[SnagIt]' section to your 'win.ini' file to change the defaults.
example:
[SnagIt]
Device=Printer
Region=Screen
Scale=Screen
Output=Mono,50
Note: The above settings are also the program defaults.
------------------------------------------------------------------
>>>>> Running "SnagIt": <<<<<
------------------------------------------------------------------
"SnagIt" may be placed on the 'Load=' line in the win.ini file, a
program item may be created, or just run with the 'RUN' option.
When "SnagIt" is first run it will check the win.ini file for a
'[SnagIt]' section. If "SnagIt" finds its win.ini section then the
operational defaults will be overwritten with the values found.
"SnagIt" automatically runs minimized (as an icon). Double clicking
on the "SnagIt" icon will bring up its main window and menu. The
current operation parameters are displayed on the client area. Use
the menus to change "SnagIt's" parameters.
To initiate a screen capture press the Control-Shift-P keys at the
same time.
To CANCEL a screen shot: If REGION, WINDOW, or CLIENT region options
are in effect, the capture may be canceled by pressing the right
mouse button.

Any and all comments are appreciated.
Letters or CompuServ Mail are the prefered method of communication.
Thanks for looking at "SnagIt". I hope that it will be a benefit to
the programming / computer industry.
