Rendering Snapshots


Snapshots of the viewport can be rendered to any size, limited only by your graphics hardware and available memory. When rendering snapshots objects are rendered to the highest level of detail. This may take time for large projects. To open the snapshot options dialog, select the Tools | Snapshot menu item or click on the Snapshot options icon in the Snapshot toolbar.

Setting the Image Size or Scale
Method
Sets how the image size is determined, the following options are available
Image Dimensions
The size of the image is set by directly by the width and height values and defaults to the viewport dimensions. if Lock aspect to AOI is checked changes to width or height update the other to keep the proportion of the image the same as that of the area of interest.

Clicking 1:1 sets the image size to the Area of Interest size.
Image Scale
The size of the image is calculated based on a scale of Units/Pixels. If this results in a very large image a warning appears before the image is rendered. The scale can be set as pixels per unit or units per pixel.

Changes the units in which distances are displayed.

Calculate Print Size
Opens a the print size calculator. This sets the image scale according to the scale and dpi of the output image for the purposes of printing. Note that the dpi is not encoded in the image, you must ensure you are printing at the correct dpi in order to achieve the correct scale.
This option is only available in orthographic projection
Image Size
This is the size of the output image in pixels. The image size defaults to the current viewport dimensions. if Lock aspect to AOI is checked changes to width or height update the other to keep the proportion of the image the same as that of the area of interest.

Clicking 1:1 sets the image size to the Area of Interest size.
Area of Interest
This is area of the viewport that you want to take a snapshot of. You can type the values in directly or use Pick to pick an area directly on the viewport using the mouse. All sets the area of interest to the entire viewport.

Area of interest can only be set in Orthographic mode.

Rulers, Scale and Positioning Output
The following options will only be available in orthographic projection. Rulers always start from the top left corner of the image and are not aligned to the coordinate system.
Minor
Minor ruler markings will be added to the output image. The spacing of these marking can be specified in the number box to the right.
Major
Major ruler markings will be added to the output image in a heavier line.
Scale Text
Adds text to the image to indicate the image pixel / units scale and pixel ratio. This can be used to scale the image in a CAD package. The colour of this text can be set using the control below.
Datums
Camera Position
Camera Direction

Image Formats, Effects and Output
Image File
The drop down control specifies the output file format. Currently the following file formats are supported:

Support for EPix format for import into Piranesi is planned for a future release.

The options button opens any options for the selected file format. For some format there maybe no options available. In this case the button has no effect.
Effects
Anti-aliasing smoothes the output image to give a higher quality output. This uses a multi-pass technique that increases image rendering time. You can set the antialiasing level (low, med, high). Higher levels require more passes and therefore take more time.
File
Specifies the output file name of the image. You can type this in directly or click on browse to select a file location.

if Numbered is checked a sequential number will be appended onto the file name. This number is incremented each time you take a snapshot providing a convenient method to name snapshots automatically without having to reopen the options dialog.

You can manually adjust the current number in the number box
Take Snapshot
Renders the area of interest in the current view to the file specified. This has exactly the same effect as clicking on the 'Take Snapshot' icon in the toolbar.

Canceling the dialog returns all values back to their previous settings.
