Change in inner data representation

If command Resample is selected, dialog window showed on picture 3.13 appears. There are two columns of fields -- Original and Destination. Fields in column Original shows current values and unacessible for editing. In the fields in column Destination new values entered.

If you want to change values on the Z-axis, check menu items Z Scale or Z Offset. Inner data format of FemtoScan software is described here -  . In the field Bit size user can enter a height per one bit from these two bytes, in which height data stored. The difference between Bit size field of Resample window from Bit size field of Resolution window (see ) is in that, in the first case program change value of the two byte integer numbers (that is inner data representation) according to the field value, and in the second case the program change in accordance with the field value only coefficients, that needs to convert these integer numbers to real height data.

In a RMS field standard deviation of the surface height is indicated.

<Z> field indicate the height in inner data representation, which will correspond to average surface height.

Fields Width and Height can be used to change the number of the points in the image.
