Map Export as Image

Function Description

The map in the current map window can be exported as common image formats. Supported formats include *.bmp, *.jpg, *.png, *.gif, *.eps, *.tif, etc.

Ensure no objects are selected in the current map.

Right-click the map and select "Map Export as Image" from the context menu to open the "Export as Image" dialog.

In the Export Settings section, configure parameters including save path, filename, resolution, and background transparency. Specific operations:

File name: Click the right button to set path and name in the "Save" dialog, or directly input in the text box.
Resolution: Set output image resolution (range: 1-2000). Values exceeding maximum will trigger warnings. Supported formats: *.bmp, *.jpg, *.png, *.tif. Default: 96 DPI.
The application estimates compressed file size based on resolution and export bounds. For PNG format, users will be prompted to export as PDF when image size exceeds limits (77MB for 64-bit OS/12MB for 32-bit OS). Details see Export to PDF.
Width: Displays output image width in pixels.
Height: Displays output image height in pixels.
Background Transparency: Available for *.png/*.gif formats. Check to enable transparent background.

In the Export Bounds section, set map export range and optional split output by fields:

Export Bounds: Four range-setting methods:
- Whole Map: Uses union of all layers' ranges
- Current Windows: Uses current map window bounds
- Select Objects: Two sub-methods: Select Object (select objects via click/drag) or Draw Bounds (draw rectangular area)
- Copy and Paste: Copy current bounds and paste coordinates to other range settings.
Split Output: When enabled, outputs map in specified range as separate images per split field. Specify dataset/field directly or select objects:
- Datasource: Select source datasource
- Dataset: Select target dataset
- Split Field: Basis for splitting. Can be:
  - Existing field from dropdown list
  - Field expression via Expression... in SQL Expression dialog

Caution:

Thematic map's Flow and No Overlap features are disabled during export. Disable these features beforehand.
Background Transparency auto-enables with Split Output.
Split objects must be complete within export range.
Objects beyond Crop Display Range (set in Map Properties->Range) won't output when splitting.
