art-sharp 2.0.0.0 Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. Defines an affine transformation To be added System.Object Method System.Void Sets up a rotation matrix. Where to store the resulting affine transformation. Rotation angle in degrees. To be added Method System.Double Finds the expansion factor, i.e. the square root of the factor by which the affine transform affects area. The affine transformation. The expansion factor. In an affine transform composed of scaling, rotation, shearing, and translation, returns the amount of scaling. Method System.Void Set up the identity matrix. Where to store the resulting affine transform. To be added Method System.Void Flips the affine transform. Where to store the resulting affine transform. The original affine transformation. Whether or not to flip horizontally. Whether or not to flip vertically. Both horz and vert false results in a simple copy operation. True for both results in an 180 degree rotation. Method System.Void Converts an affine transform into a bit of PostScript code that implements the transform. The resulting string. The affine transform. Special cases of scaling, rotation, and translation are detected, and the corresponding PostScript operators used (this greatly aids understanding the output generated). The identity transform is mapped to the null string. Method System.Void Sets up the inverse of the given transformation. Where the resulting affine is stored. The original affine transformation. The inverse is in the classical sense; src_affine multiplied with dst_affine, or dst_affine multiplied with src_affine will be (to within roundoff error) the identify affine. See Method System.Void Multiplies two affine transforms together, i.e. the resulting dst is equivalent to doing first src1 then src2. Where to store the resulting affine transform. The first affine transform to multiply. The second affine transform to multiply. To be added Method System.Void Setup a shearing matrix Where to store the resulting affine transformation. Shear angle in degrees. To be added Method System.Boolean Determines wether a matrix is rectilinear, i.e. grid-aligned rectangles are transformed to other grid-aligned rectangles. The affine transformation to test. if the matrix is rectilinear. The implementation has epsilon-tolerance for roundoff errors. Method System.Boolean Determine if two matrices are equal. An affine transformation. Another affine transformation. if the matrices are equal. Equality is verified with epsilon-tolerance for roundoff errors. Method System.Void Sets up a translation matrix. Where to store the resulting affine transform. X translation amount. Y translation amount. To be added Method System.Void Sets up a scaling matrix. Where to store the resulting affine transform. X scale factor. Y scale factor. To be added Constructor To be added To be added Method Art.Point Apply an affine transform to an . The original point. The affine transform. The resulting point after performing the transform. To be added
