Drawable.DrawRaster Method
Draws a raster.
DrawRaster(Raster raster, RasterFilter filter, System.Int32 alpha, Rectangle clipRectangle)
Draws a raster.Syntax
public void DrawRaster (
Raster raster,
RasterFilter filter,
System.Int32 alpha,
Rectangle clipRectangle
)Parameters
The raster to draw.
The raster filter to use.
An alpha value used to adjust the opacity of the raster, in the range 0 to 255.
Limits the area of the raster to draw.
Remarks
The method draws a raster. The original raster is assumed to have its own coordinate system with the lower left corner is at (0, 0) and the upper right corner is at (c - 1, r - 1), where c and r are the number of columns and rows of the raster, but these corner coordinates are then transformed to screen coordinates by the current Transform.
The alpha value can be used to add transparency to the filter, a value of 255 means no extra transparency.
If a clipRectangle is specified (with positive width and height), only the part of the raster inside the clip rectangle is drawn. The rectangle must be expressed in the original coordinates of the raster, where (0, 0) and (c - 1, r - 1) are opposite corners.
