50 Chapter 5 - MonitorMouse for DOS
Mickey/Pixel Ratio Flag (-r)
This flag specifies the default "mickey-to-pixel ratio" for horizontal and vertical
motion. A "mickey" is a unit of distance, typically 1/200 of an inch. Consequently,
the mickey/pixel ratios specify how far the mouse must move for the cursor to
move a given number of pixels. Because MonitorMouse for DOS uses absolute
positioning rather than relative motion, your finger may appear out of calibration
when using certain programs which use mickeys rather than coordinates. This flag
can help you correct the pixel-to-mickey calibration.
The -r flag is required with some mickey-based (relative motion) programs.
Specifically, it is needed only if all the conditions below are true:
•
The program uses motion from the mouse driver rather than coordinates.
•
The program draws its own cursor or cursor bar.
•
The program performs its own mickey-to-pixel conversion, and changes the
ratios without informing the mouse driver through mouse function 15.
If your application fits these criteria, adjusting the ratios through trial-and-error
may keep the cursor in better calibration with your touch. Increase the value if the
cursor falls behind your finger when sliding, or decrease it if the cursor speeds
ahead of your finger.
The defaults for this flag are the same as they are for the mouse driver:
-r 8,16
namely 8 for X and 16 for Y.
Jump Flag (-j)
The -j flag is only of concern in programs which use mickeys (relative motion)
rather than coordinates. With -j+, a new touch will emulate mickey motion to the
new touch location from the point of last release, thus causing the cursor to jump
to your fingertip. With -j-, a new touch will not simulate any motion to that point.
The default is -j-.
