Exporting a Rendered Drawing with HDRI Export

The High Dynamic Range Image (HDRI) command creates an HDR file, which is a good choice for export when touching-up the image in an imaging program; the exported image is “lossless” and will not have quantization artifacts when color or exposure is further adjusted after export.

Rendered files can also be exported in a variety of image file formats as described in Exporting an Image File. It is possible to export all or part of a drawing depending on the selected export format.

To export a file in HDR format:

1. Select the rendering mode to use for the export (Artistic/Custom/Fast/Final Quality Renderworks) and render the image.

2. Select File > Export > Export High Dynamic Range Image (HDRI).

The Export Image File dialog box opens. Specify the dimensions and resolution for the exported image.

►    Click to show/hide the parameters.

Parameter	Description
Export Area
All Visible Objects	Exports an image that includes all visible objects (objects do not have to be currently on screen to be considered visible)
Current View	Exports an image that is exactly as it displays on the current screen
All Pages as Single Image	Not applicable for HDRI export
Each Page as Separate Image	Not applicable for HDRI export
Marquee	Exports the portion of the image specified with a marquee box. Select this option and then click Draw Marquee to temporarily close the dialog box. Click, and then drag to specify the area for export; the marquee dimensions are displayed on the Data bar. Click to set the export area and return to the Export Image File dialog box. The Pixel Dimensions of the image are automatically set to the marquee dimensions.
Dimensions
Lock Aspect Ratio	Select to maintain the image aspect ratio when specifying dimensions
Resolution	Specifies the printed image resolution in pixels per inch
Pixel Dimensions
Width/Height	Specifies the exported image dimensions; if Lock Aspect Ratio is selected, changes to one dimension will update the other to maintain the aspect ratio
Print Size
Width/Height	Specifies the printed image dimensions in the selected Unit; if Lock Aspect Ratio is selected, changes to one dimension will update the other to maintain the aspect ratio
Units	Select a unit to apply to the Print Size parameters
Preview	Displays a rendered or wireframe preview according to the current settings
Render	Updates the preview with a rendered view using the currently set rendering option
Wireframe	Updates the preview with a wireframe view

Reset all plug-in objects that require a reset prior to exporting	Automatically resets plug-in objects that require an update (such as data stamps) before exporting
Export Georeferencing File (Architect or Landmark required)	Available only if the current design layer is georeferenced. Along with the image file, exports a worldfile that describes the exported image’s location, scale, and rotation in the geographic coordinate system. If multiple georeferenced layers are visible, the worldfile will be written according to the topmost layer. See GIS and Georeferencing for more information.

3. Click Save.

The Export OpenHDR File dialog box opens.

4. Specify the export file name and destination, and then click Save. The image is re-rendered automatically before export.
