RomanMosaic method (ILEADRasterProcess)

Syntax	short RomanMosaic(ILEADRaster * pRaster, long lTileWidth, long lTileHeight, long lBorder, ShadowDirectionConstants ShadowAngle, long lShadowThresh, OLE_COLOR crColor, long lFlags);
Overview	Refer to Applying Artistic Effects.

Remarks

(Raster Pro and above only) Segments the image into rectangular or rounded rectangular tiles and fills them with a color chosen randomly from the colors of the tile’s pixels.

Use this method to divide the bitmap into rectangular or rounded rectangular tiles and then fill each tile with a color chosen randomly from the colors of each tile’s pixels.

As an example, if you use the following figure:

$image\diffuseglowbefore.gif$

And you call the RomanMosaic method using the following values:

Parameter	Value
lTileWidth	2
lTileHeight	2
lBorder	20
ShadowAngle	na
lShadowThresh	na
crColor	Black
lFlags	RMN_BOTH \| RMN_FLAT

The following figure results:

$image\HummingbirdRomanMosaic.gif$

Use the Mosaic method to impose a mosaic effect on a bitmap by dividing the bitmap into tiles of a specified size and changing the color of all pixels in each tile to the average color of pixels within the tile.

Use the Pixelate method to divide the bitmap into rectangular or arc-shaped cells and then recreate the image by filling those cells with the minimum, maximum, or average pixel value, depending upon the effect that was selected.

Use the MosaicTiles method to make an image look like a mosaic made from tiles. Tiles can be rectangular or arc-shaped, depending upon the coordinate system used to draw the tiles.

Use the Pointillist method to convert image colors into randomly placed dots to create a pointillist painting, using a background color to fill the area between dots.

This method can process the whole image or a region of the image. If a bitmap has a region, the effect is applied only to the region.

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

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.
