Squeezy Commands
These commands relate to the ‘Squeezy’ hardware option for Imagestore 2
and Imagestore 3. Please refer to the table on page 113.
The Squeezy DVE is controlled by using preset positions and sizes, and
performing moves to specified preset. Up to 255 presets are available (0x1to
0xFF). Preset 0 cannot be overwritten, and is always the nominal
‘unsqueezed’ image.
Note: The Squeezy control comments only apply to Imagestore 2, and
also Imagestore 3 operated with Squeezy hardware. Please refer
to page 119 for all other products.
Set Squeeze Preset W0
This command modifies the basic size and position parameters for a squeeze
preset. XY position and XY size are floating point values (converted to
16.16), where the active video area is defined as 1.0 high by 1.0 wide. The
‘position’ is the position of the centre of the squeezed image.
Example:
To place the image in its nominal size and position, X position = Y Position
= 0.5, X Size = Y Size = 1.0.
Example:
To shrink the image to occupy the upper-right quarter of the screen:
X-Position = 0.75, Y-Position = 0.25, X-Size = 0.5, Y-Size = 0.5
