LEADTOOLS now can compare all or part of one bitmap with all the areas of the same dimensions in another bitmap and finds those areas that match according to the measure of correlation.
LEADTOOLS now can be used to improve the brightness of an image by adding bitmaps within a bitmap list.
LEADTOOLS now can increase or decrease the brightness in the bitmap by multiplying the colors in the specified bitmap.
LEADTOOLS now filters a specified bitmap to detect colors in a specified intensity range in all planes or a specific plane.
LEADTOOLS now can combine image data from the source bitmap (the slave) and the destination bitmap (the master), using a perspective warp.

LEADTOOLS now supports averaging the bitmaps in a list, eliminating random noise contained in the images.
LEADTOOLS now transforms the bitmap into a binary image.
LEADTOOLS now deinterlaces video source images by removing the black lines. It proceeds by merging lines in the image together and/or blending them together.
LEADTOOLS now smoothes the edges of a bitmap.
LEADTOOLS now can detect the edges in a bitmap by applying a statistical filter that analyzes the variations of colors in all directions around each pixel.
LEADTOOLS now can find the skeleton of regions or objects in a binary bitmap.
LEADTOOLS has added four new handling messages for image list:

LEADTOOLS now converts a grayscale bitmap into a colored one by mixing or replacing the original values of the pixels with one or more new colors. Also it converts the image to a grayscale level by reducing the saturation of each color to zero.
LEADTOOLS now can removes holes from a bitmap region.
LEADTOOLS has improved the artistic effects by adding the following new features:
Adds shadows to a bitmap, letting you specify the threshold value, the direction of the light source, and whether the shadows are colored or grayscale.
Adds effects that simulate random color changes, scratches, dust and pits, making a bitmap look like it was made from an old film.
Splits the image into square or rectangular blocks. If the blocks are square, rotates each block by 0, 90, 180, or 270 degrees. If the blocks are rectangular, flips the blocks around the X-axis and Y-axis.
Adds light to the bitmap according to a function-based distribution. This functional light will be generated by one of the following methods: linear, quadratic, sine, cosine, or using freehand points.
Splits the image into square blocks and randomizes these blocks inside the image.
Divides the image into a certain number of rings. Each ring is rotated according to a rotate angle. The rotate angle for each ring will be chosen randomly by the function or can be passed to the function.
Adds a pseudo-3D wave effect to the bitmap by drawing horizontal lines across the bitmap and basing each lines height at each point on its brightness at that point.
Divides the bitmap into segments where each segments pixels have approximately the same color (homogenous color).
LEADTOOLS now can combine image data from the mask bitmap and underlay bitmap with an underlay effect.
Wraps the bitmap along the inside or outside of an arc pattern.
Warps the bitmap to a cylindrical shape.
Shears the bitmap by the wave drawn using amplitude values
Distorts the bitmap by the wave drawn using amplitude values
Makes a bitmap look like it was painted by an impressionist painter.
Divides the bitmap into rectangular or circular cells and then recreates the image using those cells filled with the minimum, maximum, or average pixel value, depending upon the effect that was set.
Converts the bitmap from rectangular to polar coordinates and vice versa.
Warps the bitmap by pinching it toward the center or expanding the bitmap away from its center.
Rotates the bitmap pixels around a center point.

Selects a specified number of bits of an 8, 12 or 16-bit grayscale bitmap and puts them into a mask, then colors the bitmap depending on the mask. This can show bitmap variances depending on user-defined conditions.
Selects a specified number of bits from an 8, 12 or 16-bit grayscale bitmap into a mask and places the mask in a new 8, 12 or 16-bit grayscale bitmap.
