com.itextpdf.kernel.geom Documentation Differences

This file contains all the changes in documentation in the package com.itextpdf.kernel.geom as colored differences. Deletions are shown like this , and additions are shown like this.
If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.
Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a tag will cause all subsequent paragraphs to be displayed differently.

Class Matrix, constructor Matrix(float, float)

Constructs a matrix that represents translation translation. @param tx x-axis translation @param ty y-axis translation
Class Matrix, constructor Matrix(float, float, float, float, float, float)

Creates a Matrix with 6 specified entries entries. The third column will always be [0 0 1] (row, column) @param a element at (1,1) @param b element at (1,2) @param c element at (2,1) @param d element at (2,2) @param e element at (3,1) @param f element at (3,2)
Class Matrix, constructor Matrix(float, float, float, float, float, float, float, float, float)

Creates a Matrix with 9 specified entries entries. @param e11 element at position (1,1) @param e12 element at position (1,2) @param e13 element at position (1,3) @param e21 element at position (2,1) @param e22 element at position (2,2) @param e23 element at position (2,3) @param e31 element at position (3,1) @param e32 element at position (3,2) @param e33 element at position (3,3)
Class Matrix, Matrix add(Matrix)

adds Adds a matrix from this matrix and returns the results results. @param arg the matrix to subtract from this matrix @return a Matrix object
Class Matrix, boolean equals(Object)

Checks equality of matrices. @param obj the obj the other Matrix that needs to be compared with this matrix. @ return true return true if both matrices are equal @see java.lang.Object#equals(java.lang.Object)
Class Matrix, float get(int)

Gets a specific value inside the matrix.

For reference, the indeces are as follows:
I11 I12 I13 I13
I21 I22 I23 I23
I31 I32 I33 I33 @ param index an param index an array index corresponding with a value inside the matrix @ return the return the value at that specific position.

Class Matrix, float getDeterminant()

Computes the determinant of the matrix. @return the determinant of the matrix
Class Matrix, int hashCode()

Generates a hash code for this object. @return the hash code of this object @see java.lang.Object#hashCode()
Class Matrix, Matrix multiply(Matrix)

multiplies this matrix by 'b' and returns the result result. See http://en.wikipedia.org/wiki/Matrix_ multiplication multiplication @param by The matrix to multiply by @ return the return the resulting matrix
Class Matrix, Matrix subtract(Matrix)

Subtracts a matrix from this matrix and returns the results results. @param arg the matrix to subtract from this matrix @return a Matrix object
Class Matrix, String toString()

Generates a String representation of the matrix. @return the values, delimited with tabs and newlines. @see java.lang.Object#toString()
