Question

I\'m moving control(label or image) success in PictureBox. When I move, it will save control position(x, y).

Like this:

But problem is: the image re

Answer 1

If your PictureBox is in Sizemodes StretchImage or Zoom then the pixels are scaled; the Label's Location however is not. So you would have the calculate the position where to draw:

PointF stretched(Point p0, PictureBox pb)
{
    if (pb.Image == null) return PointF.Empty;

    float scaleX = 1f * pb.Image.Width  / pb.ClientSize.Width;
    float scaleY = 1f * pb.Image.Height / pb.ClientSize.Height;

    return new PointF(p0.X * scaleX, p0.Y * scaleY);
}

You would call it as PointF p1 = stretched(p0, pictureBox1);

You would draw maybe like this:

g.DrawImage(  DrawText(image, new Font(cbxFont.Text, fontSize), 
                       colorInput, Color.Transparent),
              Point.Round(stretched( CtrlPos.Location, picPreview));

If you also want to correct the size you can use a similar function..

If the SizeMode is CenterImage the pixels are not scaled but most likely transposed and a correction is necessary as well.

For the other direction simply switch denominator and numerator in the fractions!
