Changes from Version 7.0 to Version 8.0
Version 8.0 of the LEADTOOLS ActiveX has changed from version 7.0 as follows. (For step-by-step help, refer to Upgrade Instructions.)
New properties for ActiveX behavior let you load images using OLE drag-and-drop, make the control transparent, and give the control a three-dimensional frame.
The paint effects capabilities have been enhanced, with control over the speed and granularity of each effect, and with hundreds of new variations, including overlays of text and graphic shapes.
Drawing tools have been added, so that you no longer need to rely on Windows GDI functions for drawing shapes or adding text to the control or the bitmap.
New methods let you use an automated rubberband to zoom in on a selection or trim a bitmap, without translating mouse coordinates to bitmap coordinates.
Region processing is now available in the LEADTOOLS Pro toolkits.
[Express editions only] You can now achieve faster rotation in 90-degree increments by applying a rotated view perspective to the bitmap.
You can now control the brightness and contrast of displayed images, without modifying the bitmap data.
New image processing functions give you more control over erosion or dilation of dark objects.
Other new image processing functions let you apply artistic effects to give an image the appearance of an oil painting or to simulate the accidental exposure of photographic film to light.
LEADTOOLS functions now preserve alpha-channel information. You can also get and set the alpha channel in 16- and 32-bit bitmaps.
TIFF file support now includes reading and writing of 32-bit images, images with PackBit compression, and images with CMYK or YCbCr color space.
BMP file support now includes reading and writing of RLE-compressed images.
You can now read and write Windows Icon (ICO) and Cursor (CUR) files.
You can now read and write EXIF files.
You can now read and write Microsoft FAX (AWD) files.
[Express editions only] You can now read and write DICOM files.
You can now read and write comments in all of the files formats that support comments, including TIFF, GIF, DICOM, and EXIF files.
