Cutting raster map under the nomenclatures |

|
If you choose several nomenclatures from the list, the copying is made by stream. Name of the BMP-file is formed by the appropriate nomenclature. Choice and change of area: Selected area will be used for definition nomenclatures which are fallen into it's area. All region button installs as area all region. For choice of a fragment it is necessary to click Select button, then to mark area on a map by choice of two points. Cutting raster map under the nomenclatures dialog will open repeatedly with the refreshed list of the nomenclatures. Change button is intended for change of a selected fragment. By rasters button installs dimensions of area on overall dimensions of all displayed rasters. Thus usage of a frame of the raster is allowed for (Show extracted portion of raster). The choice and change of a fragment can be made multiply. It is necessary to indicate a demanded scale of the topographic map for creation of the nomenclatures list (Scale field).
At copying of a raster map fragment created by mosaic of the rasters, it is necessary to indicate the following characteristics of the saved image: - resolution (Resolution field); - element size in meters ( Element size (m) field); - bit's quantity onto element (Bits per pixel field).
If nomenclature, selected in the list, completely falls onto one raster, or only one raster is displayed in the document, then above listed parameters are taken from this raster. On fragment sizes (appropriate to the current nomenclature) and specified parameters the size of the saved file (File size (bytes) field) is estimated. Usage of the settings file: For remembering of filled by you characteristics of saved image the adjustment file is envisaged. At loading BMP file into a raster map it is possible to use the built here adjustment file for automatic fixation of the loaded image. For usage of the settings file of the raster tick off File of parameters field. The name of settings file is forming by name of the appropriate BMP-file. Reset button is intended for marking (cancellation of marking) of all nomenclatures list. Overlapping field sets an indent from overall dimensions of the nomenclature for definition of a fragment of the copied raster. Way of activation of Cutting raster map under the nomenclatures mode: In Raster Editor (Tools \ Raster Editor) you must open Work with raster subpanel by pressing the like button on the panel and select Cutting raster map under the nomenclatures button.

This mode is intended for copying a part of a raster map, restricted by nomenclature of the topographic map, in the file of BMP format.
