TIECanvas.CreateMatrix

Declaration

function CreateMatrix(m11, m12, m21, m22: single; dx, dy: single): Pointer;

Description

Creates a matrix to be used to apply a world transformation to the canvas content (using MatrixTransform).
Afterwards, you must free the matrix, using DeleteMatrix

Note: Use ResetTransform to reset the transformation

GDI+ Method: GdipCreateMatrix2

Example

// Use a matrix to position the drawing of a rectangle

// Create the transformation matrix
matrix := IECanvas.CreateMatrix( 2.33,       // m11
                                 0,          // m12
                                 0,          // m21
                                 -2.33,      // m22
                                 -171.93,    // dx
                                 1091.96 );  // dy
try
  // Apply the matrix transformation
  IECanvas.MatrixTransform( Matrix );

  // Now draw the rectangle with the transformation applied
  IECanvas.Rectangle( 50, 50, 100, 100 );
finally
  // Free the matrix
  IECanvas.DeleteMatrix( Matrix );
end;
