Example 16 with VoiceSpacing

use of com.xenoage.zong.musiclayout.spacing.VoiceSpacing in project Zong by Xenoage.

the class MeasureElementsSpacerTest method testNeedAdditionalSpace.

/**
 * If there is not enough space left for the measure elements,
 * the voice spacings have to be moved to create enough space.
 * To understand the following sketch, have a look at the comments
 * in {@link MeasureElementsSpacer}.
 * <pre>
 * enough space:
 * beat:     0   2   4   6   8
 * offset:   3 5 7 9  13  17  21
 *           . . . . . . . . . .
 * clef:         *[clef]*          (on beat 4)
 * voice 1:   o      2
 * voice 2:    1          o
 * </pre>
 * Between VE1 and VE2, there are 6 spaces.
 * Assuming a padding width of 1 and a clef width of 6,
 * the clef can be moved two spaces to the left, but this is not
 * enough. All elements at or after beat 3 have to be moved 2 spaces
 * to the right.
