How interpretation MS-EMF Header object properties - Bounds, Frame, Device and Millimeters?

Question

I'm implement rendering MS-EMF to raster image tool.
Parser by specification work's fine. But i have interpretatioin 2.2.9 Header Object properties when rendering problem, not enough information in the specification.

To convert from LOGICAL to DEVICE coordinates use current MapMode. How to interpret them (especially interesting MM_ISOTROPIC and MM_ANISOTROPIC) can look at gdi, for example here.

Now, i'm trying to specify the position and size of the whole image:

var minPoint = new PointF(header.Bounds.Left, header.Bounds.Top);
var maxPoint = new PointF(header.Bounds.Right, header.Bounds.Bottom);

float imageWidth = maxPoint.X - minPoint.X;
float imageHeight = maxPoint.Y - minPoint.Y;

float shiftX = -minPoint.X;
float shiftY = -minPoint.Y;

var globalCanvas = new CanvasClass(options.PageWidth, options.PageHeight);
globalCanvas.RenderTransform = new DrMatrix(1, 0, 0, 1, 0, 0);

float scaleX = options.PageWidth / (maxPoint.X + shiftX);
float scaleY = options.PageHeight / (maxPoint.Y + shiftY);
float minCommonScale = Math.Min(scaleX, scaleY);

if (minCommonScale > Epsilon)
{
    globalCanvas.RenderTransform.Scale(minCommonScale, minCommonScale);
}

globalCanvas.RenderTransform.Translate(shiftX, shiftY);

but i don't understand how to use all properties - Bounds, Frame, Device and Millimeters - and the result image is stretched or not correct scaling or position of the image is not correct.

How them interpret?

Example 1.
emf file
header:

Bounds: (0, 0) - (579, 429)
Frame:  (0, 0) - (10000, 10000)
Device: 1855, 1034
Millimeters:    320, 240  

and total 4 records:

SelectObject(hDC, (HGDIOBJ)GRAY_BRUSH);
Ellipse(hDC, 0, 0, 99, 99);
SelectObject(hDC, (HGDIOBJ)BLACK_BRUSH);
Ellipse(hDC, 480, 330, 579, 429);

result:

but we must see ex1-ethalon
Interestingly, viewers display ehalon incorrect, except the windows standard viewer:

Example 2.
emf file
header:

Bounds: (960, 210) - (3396, 2429)
Frame:  (6772, 1481) - (23969, 17143)
Device: 2892, 4125
Millimeters:    204, 291

result (incomplete rendering yet): but we see ethalon (attention on the image position):
