Tunnel method (ILEADRasterProcess)

Visual Basic example

Visual C++ 5.0 example

 

Syntax

short Tunnel (ILEADRaster *pRaster, short CenterX, short CenterY, short iZValue, short iDistance, short iRad, short iRepeat, short iRotationOffset, short iStretch, short iStartBright, short iEndBright, short iBrightLength, OLE_COLOR crBright, OLE_COLOR crFill, long lFlags);

Overview

Refer to Applying Artistic Effects

Remarks

(Raster Pro and above toolkits) Places the bitmap inside a tunnel along the Z-axis.

This metho shows the effect of placing a bitmap inside a tunnel along the Z-axis. An external light source of the specified color and brightness may be shined on the bitmaps. The brightness may vary along the z-axis according to the iBrightLength value.

Changing the camera center point, the rotation angle and the viewing screen Z-offset will simulate moving along the axis.

If the bitmap has a region, the effect will be applied on the region dimensions only.

This method supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

For an example, see the following figure:

image\Tunnel_before.gif

The following figure shows the same bitmap, after the effect has been applied:

image\Tunnel_after.gif

To obtain this effect, the following settings were used with the function:

CenterX, CenterY = (200,200)

iZValue= 0

iDistance= 200

iRad= 200

iRepeat= -1

iRotationOffset= 75

iStretch= 25

iStartBright= 0

iEndBright= 100

iBrightLength= 45

crBright= RGB(255,255,255)

crFill= RGB(255,255,255)

lFlags= PLANE_FILL_CLR|TUN_AXIS_WIDTH

This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
