|
CreateMirroring(Point2d, Point2d) | Creates a matrix that reflects stuff over the line passing through two given points. |
|
|
CreateRotation(double) | Computes a new matrix which is a pure rotation matrix. |
|
|
CreateRotation(double, Point2d) | Computes a new matrix that represents rotation around a given point. |
|
|
CreateScaling(double) | Computes a new matrix which is a pure scaling matrix where x and y scale is the same. |
|
|
CreateScaling(double, Point2d) | Computes a new matrix which is a scaling matrix with a given origo. |
|
|
CreateScaling(double, double) | Computes a new matrix which is a 'stretch' matrix,that is scaling in x and y might be diffrent. |
|
|
CreateScaling(double, double, Point2d) | Computes a new matrix which is a 'stretch' matrix using a given origo, that is scaling in x and y might be diffrent. |
|
|
CreateShearing(double, double) | Returns a new shear matrix, which has its x axis is tilted xshearRadians from local x axis. y axis is tilted yshearRadians from local y axis. The shearing radians are clamped to be between -89 to 89 degrees. |
|
|
CreateTranslation(double, double) | Creates a translation vector using two doubles for dx,dy. |
|
|
Eigenvalues(out double, out double) | Calculates the eigenvalues of a 2x2 matrix |
|
|
Eigenvector(double) | |
|
|
ExtractRotation() | Extract the rotation portion of the matrix. |
|
|
ExtractScaling() | Extracts the scaling portion of the matrix. |
|
|
ExtractTranslation() | Extract the translation portion of the matrix. |
|
|
ExtractTranslationVector() | |
|
|
IsMirroring() | Checks if this matrix, when applied on an object will reflect it, for example if the direction of an arc will switch from CW to CCW when transformet with it. |
|
|
IsUniform() | Checks if the matrix contains a uniform scaling |
|
|
SetIdentity() | Modifies the matrix in-place so that it is a identiy matrix. |
|
|
ToString() | Creates a string suitable for debugging purposes. |
