示例1: findStartOfStaffs
private static int findStartOfStaffs(Bitmap bitmap)
{
var x = 0;
while (!bitmap.Column(x).Any(pixel => pixel == true))
{
x++;
}
log("Staffs found at {0}.", x);
return x;
}示例2: noteBoundsAt
private static Rectangle noteBoundsAt(Bitmap bitmap, int x, int staffDistance)
{
int? minY = null, maxY = null;
var endX = x;
do
{
var yMinMax = noteTopBottomAt(bitmap.Column(endX).ToArray(), staffDistance);
if (yMinMax == null)
break;
if (!minY.HasValue || minY > yMinMax.Item1) minY = yMinMax.Item1;
if (!maxY.HasValue || maxY < yMinMax.Item2) maxY = yMinMax.Item2;
endX++;
} while (true);
if (!minY.HasValue)
return null;
return new Rectangle { X1 = x, Y1 = minY.Value, X2 = endX, Y2 = maxY.Value };
}示例3: enumerate
public static IEnumerable<Note> enumerate(Bitmap bitmap)
{
//log("Skipping to start of staffs");
var x = findStartOfStaffs(bitmap);
var outsideStaffIndexes = staffPositions(bitmap.Column(x).ToArray());
log("Staff indexes: {0}", string.Join(", ", outsideStaffIndexes));
eraseStaffs(bitmap, outsideStaffIndexes);
var staffThickness = outsideStaffIndexes[1] - outsideStaffIndexes[0];
var staffDistance = outsideStaffIndexes[2] - outsideStaffIndexes[0];
log("Staff heights: {0}", staffDistance);
var notePositions = getNotePositions(outsideStaffIndexes).ToArray();
while (x < bitmap.Width)
{
//log("x={0}", x);
var noteBounds = noteBoundsAt(bitmap, x, staffDistance);
if (noteBounds != null)
{
var centerX = (noteBounds.X1 + noteBounds.X2) / 2;
var centerY = (noteBounds.Y1 + noteBounds.Y2) / 2;
log("At {2}-{3}; Found note at: ({0}, {1})", centerX, centerY, noteBounds.X1, noteBounds.X2);
var duration = durationAt(bitmap, centerX, centerY + staffThickness);
var pitch = pitchAt(centerY, notePositions);
yield return new Note { Pitch = pitch, Duration = duration };
