Isadora Manual v1.3 - TroikaTronix

• Maximum Value: The maximum possible value for this slider. Can be any
number. (It is permissible for the maximum value to be less than the
minimum. In this case the slider value will decrease as you move it from left
to right or from bottom to top.)
• Step: Determines the minimum of the step between values. When Step is set
to zero, this setting has no effect. When set to a value greater than zero, the
control value will step by this amount as it goes from the Minimum Value to
the Maximum Value. For example, if the minimum is set to 1, maximum is set
to 10, and step is set to 1, the slider will have 10 discrete steps (1, 2, 3, … 8, 9,
10). Setting step to 1 may be the most common setting, as it allows you to
send only integer values (i.e. no numbers after the decimal point) if desired.
Note however that counting starts at the value given by the Minimum Value
setting. If you set minimum to 1.5 and maximum to 10.5 in the example just
given, the 10 steps would be 1.5, 2.5, 3.5…10.5.
• Display Value: When this box is checked, the slider will display its value as a
number. Vertical sliders display this number at the bottom; Horizontal sliders
display the number to the right.
• Display Format: Determines how the number is formatted when the Display
Value parameter is turned on. There are three choices: 123, 123.4, or 123.45.
The first displays no decimal point, the second one number after the decimal
point, and the third displays two. If Display Value is turned off, this setting
has no effect.
• Color: Sets color of the slider. The color you choose will be the color of the
indicator – the background of the slider will be a darker shade of the same
color. To change the color, click on the colored box. A Color Picker control
will appear, allowing you to choose a new color. Note: if you are using a
Picture to draw your button (see below) this setting has no effect (v1.1).
• Background Picture (v1.1): Set this to the media index of a Picture in the
Media window to provide a custom background for your slider. The picture
will be scaled to fit the rectangle that encloses the slider – to prevent scaling,
set the width and height inputs to match the size of the picture. Note that any
alpha channel information encoded into the picture is used when drawing the
image on its background, allowing you to create unusual shapes, drop
shadows, etc.
• Thumb Picture (v1.1): Set this to the media index of a Picture in the Media
window to provide a custom “thumb” (the moving indicator) for your slider. If
the slider is horizontal, the thumb will be scaled vertically to match the height
of the slider, but the width will remain unchanged. If the slider is vertical, the
thumb will be scaled horizontally to match the width of the slider, but the
height will not be changed. Note that any alpha channel information encoded
into the picture is used when drawing the image on its background, allowing
you to create unusual shapes, drop shadows, etc.
