Declaration

function ProjectDraw(Source: TIEBitmap; centerDestX: Integer; centerDestY: Integer; destWidth: Integer; destHeight: Integer; depth: Double; translateX: Integer; translateY: Integer; rotateX: Double; rotateY: Double; specularAlphaMin: Integer; specularAlphaMax: Integer; mergeAlpha: Boolean = false): TIEQuadCoords;
function ProjectDraw(Source: TIEBitmap; centerDestX: Integer; centerDestY: Integer; scale: Double; depth: Double; translateX: Integer; translateY: Integer; rotateX: Double; rotateY: Double; specularAlphaMin: Integer; specularAlphaMax: Integer; mergeAlpha: Boolean = false): TIEQuadCoords;

Description

Draw the source bitmap over current layer, performing translations, rotations and perspective transform.

Parameter	Description
Source	Source bitmap to draw
centerDestX	Horizontal position of center of destination position
centerDestY	Vertical position of center of destination position
destWidth	Destination bounding box width, not including specular bitmap. The resulting bitmap will be adapted (but not stretched) to this size
destHeight	Destination bounding box height, not including specular bitmap. The resulting bitmap will be adapted (but not stretched) to this size
scale	Replaces destWidth and destHeight in the second overload. Specifies a multiplier of the original size (1=same size, 0.5=half size, etc..)
depth	Destination depth of field
translateX	Horizontal offset in 3D space (before perspective projection)
translateY	Vertical offset in 3D space (before perspective projection)
rotateX	X axis rotations in 3D space (before perspective projection). Angles are in degrees
rotateY	Y axis rotations in 3D space (before perspective projection). Angles are in degrees
specularAlphaMin	If >-1 a reflection bitmap will be drawn, using specified alpha range
specularAlphaMax	If >-1 a reflection bitmap will be drawn, using specified alpha range
mergeAlpha	If image alpha channel is merged with the background image

Returns coordinates of four points of stretched bitmap.

Note: If the image PixelFormat is not ie24RGB, it will be converted

Example

// Project Draw image at 200, 200 (center), inside a box of 150x150, depth 400, rotating by 30° on Y axis, with specular effect
ImageEnView1.IEBitmap.Allocate( 600, 600, clBlack );
ImageEnView1.Proc.ProjectDraw( bmp,        // Source
                               300, 160,   // Dest pos (Center)
                               300, 300,   // Dest size
                               400,        // Depth
                               0, 0,       // Translation (offset)
                               0, 30       // Rotation
                               0, 100 );   // Alpha Min/Max
