Hello,
I search a example like that.
(1,0,0,1,4,5 ) -- moving
(1,0,0,1,0,0 ) -- normal matrix
(-1,0,0,1,0,0 ) -- Mirror Y-Axis
(0,-1,0,1,0,0 ) -- Mirror X-Axis
I caluculate all in mm.
After then, I want to make a transformation.
private void MapMillimetersT oPixels(Graphic s gfx, Rectangle
rectPixels, Rectangle rectMm)
{
Matrix matrix = new Matrix();
ScaleX = (float)rectPixe ls.Width / Math.Abs(rectMm .Width);
ScaleY = (float)rectPixe ls.Height /
Math.Abs(rectMm .Height);
matrix.Scale(Sc aleX, ScaleY);
matrix.Translat e(rectPixels.Le ft - ScaleX * rectMm.Left,
rectPixels.Top - ScaleY * rectMm.Top);
gfx.Transform = matrix;
}
The zero point.
left
right
top or bottom
All corners are possible, so I need a Matrox multiplication, or?
I prefer a transformation, but I haven't here experience.
So my example is without transformation matrix.
Best regards and thanks for your help
Thomas
