Clicking on the File/Export to image
menu item provides the means for creating a new image (and digital elevation / grid) file in a number of supported formats. The export is generated from the current map project i.e. from all open layers - so an exported image can be generated from just one layer or from many layers. The image is exported in the Map area coordinate system, so this feature is appropriate for converting images between coordinate systems. Because the image export is size unlimited, the File/Export to image
function can be used to mosaic multiple layers into a single image file.
To maximize compatibility with non-TatukGIS software programs, the Editor saves the coordinate system information for an exported image:
PRJ, TAB, and World Files are saved to the same file folder as the exported image file.
To export any extent of the current project as an image file
Select extent/Visible
option later in this procedure. To take advantage of this option, adjust the extent visible within the Map area using the Zoom mode, Zoom extended mode and Drag mode features.File/Export to image

button - this invokes the Export to [chosen format]
dialog box, where the chosen format is the format selected in the Save as type

dialog box allows to adjust the image parameters: level of compression (Compression box), resolution (Resolution box) and extent to export (Select extent box).Save
button.
Compression
box together with the Resolution
box provide the quality vs. file size settings. While the resolution setting affects the physical size of the image, the level of compression defines the precision to which the exported image reflects the actual data. The higher the compression level, the smaller the exported file.Resolution
options (which influences the export file size) present a choice of three predefined resolutions: best quality (if the source data is vector, this setting sets a width of 4,000 pixels), for document (300 DPI with a width of 14 cm), and for web (600 pixels in the width). The fourth Resolution
option is custom
, which allows the user to custom define the export width, height, and DPI (dots per inch).Select extent
settings are used to define the extent of the source map to be exported. The extent options are Full
(the exported image is to be generated from the entire map extent), Visible
(the export is generated only from the currently visible extent), User defined
(the export extend is defined by entering coordinate values to define the top, bottom, right, and left limits of the extent), and Spatial selection
(active only if a spatial selection has been performed on a vector layer using any of the spatial selection tools before invoking the Export to image
feature. The spatial selection tools are: Select by Polygon, Select by Circle, Select by Rectangle, Select by Clipboard.File/Export
