SoView2DCurrentState¶

InventorModule¶

genre	`View2D`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoView2D`
definition	view2d.def
inherits from	`SoView2DExtension`

Purpose¶

The SoView2DCurrentState allows to get view dependent parameters from a currently rendered SoView2D to use them in scripting. Note that this will not work on SoOrthoView2D or when the SoView2D is used in mosaic mode.

Visible Fields¶

Pixel Spacing X¶

name: pixelSpacingX, type: Float, persistent: no¶: The pixel spacing (zoom) in millimeters. This means how big a single pixel is in world coordinates. Typically Pixel Spacing Y has the same value, because the SoView2D respects the voxel size. The values can be different though, if one of the special scale modes is used.

Pixel Spacing Y¶

name: pixelSpacingY, type: Float, persistent: no¶: The pixel spacing (zoom) in millimeters. This means how big a single pixel is in world coordinates. Typically Pixel Spacing X has the same value, because the SoView2D respects the voxel size. The values can be different though, if one of the special scale modes is used.

Visible Device Rect0¶

name: visibleDeviceRect0, type: Vector2, persistent: no¶: The top left point of the visible device rectangle of the viewer. This is the whole area of the viewer, regardless where the image is shown/zoomed.

Visible Device Rect1¶

name: visibleDeviceRect1, type: Vector2, persistent: no¶: The bottom right point of the visible device rectangle of the viewer. This is the whole area of the viewer, regardless where the image is shown/zoomed.

Image Device Rect0¶

name: imageDeviceRect0, type: Vector2, persistent: no¶: The top left point of the image. This can be outside of the visible device rectangle if the image is zoomed in.

Image Device Rect1¶

name: imageDeviceRect1, type: Vector2, persistent: no¶: The bottom right point of the image. This can be outside of the visible device rectangle if the image is zoomed in.

Visible World Rect0¶

name: visibleWorldRect0, type: Vector3, persistent: no¶: The most upper left point of the image that is visible in the viewer, in world coordinates. This can, e.g., be fed into a SoView2DRectangle to indicate the visible portion of the image on an overview image.

Visible World Rect1¶

name: visibleWorldRect1, type: Vector3, persistent: no¶: The most lower right point of the image that is visible in the viewer, in world coordinates. This can, e.g., be fed into a SoView2DRectangle to indicate the visible portion of the image on an overview image.
