shape element

The shape element defints a single shape stimulus and specifies how the shape is presented.

Syntax

<shape shapename>
/ animation = circle(duration, loopcount, start, xcenter, ycenter, radius) or path(duration, loopcount, x1, y1, x2, y2, x3, y3, ...) or points(duration, loopcount, x1, y1, x2, y2, x3, y3, ...) or size(duration, loopcount, startwidth, startheight, scale1, scale2, scale3, ...) or rotation(duration, loopcount, degrees1, degrees2, degrees3, ...)
/ color = (red value, green value, blue value) or color name or color value
/ dropposition = (x value, y value) or (x constant, y constant)
/ dropsource = value or boolean
/ droptarget = property or boolean
/ erase = true(red value, green value, blue value) or true(color value) or true(color name) or false
/ halign = alignment
/ height = numeric expression
/ hposition = x expression
/ monitor = integer
/ onprepare = [expression; expression; expression; ...]
/ position = (x value, y value)
/ rotation = degrees
/ shape = shapename
/ size = (width variable, height variable)
/ valign = alignment
/ vposition = y expression
/ width = numeric expression
</shape>

Functions

Remarks

Button stimuli provide a convenient means of overwriting previously presented stimuli during a presentation sequence, or for drawing background to be presented behind other stimuli.

Examples

The following defines a blue circle that appears on the right side of the screen:

<shape bluecircle>
/ shape = circle
/ color = (0, 0, 200)
/ position = (80%, 50%)
</shape>
