| + | You can change size and resolution of any image using menu command [[меню_операции|Operation]] -> **Resample**. This function changes discreet value for every axis X, Y, Z in inner data representation. | ||
| + | |||
| + | This function calls up a dialog window containing table with values. Every parameter corresponds to two columns **Original** and **Destination**. Fields in the **Original** column cannot be edited and show current values. In the Destination fields you can specify desired values of parameters. | ||
| + | |||
| + | If you want to change coefficients for conversion from integer data to Z height check the **Z scale** or **Z offset** box. Height corresponding to one bit of two bytes assigned for storage of height value is given in **Bit size** field. This field in **Resample** window determines the changes in integers given by two bytes in inner representation of data while the same field in [[view|View]] -> [[view_разрешение|Resolution]] window determines a coefficient of conversion the integers to height values. | ||
| + | |||
| + | Dispersion of surface height expressed in bites is specified in the **RMS** field. Since these two values are related the latter one will be changed automatically. | ||
| + | |||
| + | The **<Z>** field contains an average height of the surface in inner data representation. | ||
| + | |||
| + | To change the number of points in the image use **Width** and **Height** fields. If the **Apply to all images in the document** box is checked then all images in the file will be rescaled the same way. | ||
