#include "ltwrappr.h"

virtual L_INT LBitmap::Plane(ptCenterPoint, uZValue, nDistance, uPlaneOffset, nRepeat, nPydAngle, uStretch, uStartBright, uEndBright, uBrightLength, crBright, crFill, uFlags)

POINT ptCenterPoint;	point at which the viewer is looking
L_UINT uZValue;	viewing screen offset on the Z-axis
L_INT nDistance;	camera distance from the viewing screen
L_UINT uPlaneOffset;	distance between planes
L_INT nRepeat;	number of repeats
L_INT nPydAngle;	view angle
L_UINT uStretch;	compression factor
L_UINT uStartBright;	brightness of an external light source on the first bitmap displayed
L_UINT uEndBright;	brightness of an external light source on the last bitmap displayed
L_UINT uBrightLength;	changes in brightness along the Z axis
COLORREF crBright;	color of an external light source that is shined on the bitmaps
COLORREF crFill;	background color
L_UINT uFlags;	flags

Places the bitmap on parallel planes along the Z-axis.

Parameter	Description
ptCenterPoint	POINT structure that contains the point at which the camera or viewer is looking. It may be outside the bitmap borders.
uZValue	Viewing screen offset on the Z-axis, in pixels.
nDistance	Camera distance from the viewing screen, in pixels.
uPlaneOffset	Distance between the parallel planes.
nRepeat	Number of times the bitmap repeats along the Z-axis. If nRepeat equals 1 the bitmap will be infinitely repeated. Its range starts from 1.
nPydAngle	The view angle, off the Z-axis. This value is given in hundredths of a degree (+/-). This can be a number from 0 to 36,000.
uStretch	Value that indicates whether to expand or compress the bitmap, and by how much. If uStretch < 100 bitmap will be expanded. If uStretch > 100 the bitmap will be compressed. Use 100 to maintain the bitmap's dimensions. The value of this parameter is internally divided by 100.
uStartBright	Value that indicates the brightness of an external light source on the first bitmap displayed. Possible values range from 0 to 100. A value of 0 indicates no external light displayed on the bitmap. A value of 100 indicates an external light source with full brightness is displayed on the bitmap.
uEndBright	Value that indicates the brightness of an external light source on the last bitmap displayed. Possible values range from 0 to 100. A value of 0 indicates no external light displayed on the bitmap. A value of 100 indicates an external light source with full brightness is displayed on the bitmap.
uBrightLength	Value that indicates how much the brightness changes as you move along the Z axis. This parameter is internally multiplied by 50.
crBright	The COLORREF value that specifies the color of an external light source that shines on the displayed bitmaps.
crFill	The COLORREF value that specifies the background color.
uFlags	Flags that indicate the background color and the planes to be shown. You can use a bit wise OR (\|) to specify one flag from each group. You can use a bit wise OR (\|) to specify one flag from each group.
	The following are the flags that indicate the background color:
	Value	Meaning
	PLANE_FILL_CLR	[0x0001] Use the crFill as a background color.
	PLANE_NO_CHG	[0x0002] use the image itself as a background
	The following are the flags that indicate which planes (with respect to the Z-axis) will be shown. You can use a bit wise OR (\|) to specify more than one plane. However, you can only combine PLANE_LEFT with PLANE_RIGHT or PLANE_UP with PLANE_DOWN.
	Value	Meaning
	PLANE_LEFT	[0x0010] The plane will be displayed to the left of the Z-axis.
	PLANE_RIGHT	[0x0020] The plane will be displayed to the right of the Z-axis.
	PLANE_UP	[0x0040] The plane will be displayed above the Z-axis.
	PLANE_DOWN	[0x0080] The plane will be displayed below the Z-axis.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function shows the effect of placing bitmaps on planes along the Z-axis. These bitmaps may be placed above, below, to the left or to the right of 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 uBrightLength value.

By changing ptCenterPoint and the viewing screen Z-offset, you can simulate moving along the axis.

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

This function 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.

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

CenterPoint(x,y)= (320,256)

uZValue = 0

nDistance= 256

uPlaneOffset= 256

nRepeat= -1

nPydAngle= 0

uStretch= 100

uStartBright= 0

uEndBright= 0

uBrightLength= 50

crBright= RGB(255,255,255)

crFill= RGB(0,0,0)

uFlags= PLANE_FILL_CLR|PLANE_DOWN

This function 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 function.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
