Cutting of a matrix by selected frame

The mode is intended for saving the chosen fragment of a matrix in a file of MTW format.  

As source matrix the matrix is used which name is specified in File name of source matrix  group.      

One file of the matrix map corresponding to the chosen fragment is formed. The name of a formed matrix is necessary to set in File name of matrix  group by means of the "…." button.      

Choice and change of a saved fragment of a matrix:      

For a choice of a fragment it is necessary to press Select  button of Matrix cutting  dialogue, then to specify area on a map by a choice of two points, Matrix cutting  dialogue will open repeatedly.      

Change  button is intended for change of the chosen fragment.  

By object button installs the sizes of saved area (frame) by dimensions of the chosen object.  

The choice and change of a fragment can be made repeatedly.      

By the sizes of a fragment and parameters of a source matrix the width, height of the image and the size (in bytes) of a saved file (File size field) are estimated. The program supervises correctness of a choice of a fragment. It is necessary to choose a saved fragment on the declared matrix.      

Additional parameters:      

- Compression of a file (Compress  field). The option is intended for compression of a file of a formed matrix. It is recommended to apply compression of a matrix to economy of disk space.    

- Set border  of a source matrix. The option is intended for copying a border of a source matrix (if it has been set) into formed one.
