Changes from Version 15 to Version 16

Highlights

LBitmap::AutoBinarize coverts a colored image into an image automatically, without losing important image features such as text. This function uses several pre-processing and threshold operations which enable the user to extract the key features of any colored image. It can be adjusted to be suitable for a specific input device, such as a scanner or camera. It is ideal for making unclear document images more readable. This function is especially useful for improving recognition results (OCR, Barcode, OMR, ICR).

LBitmap::DeskewExt uses fast pre-processing algorithms to provide the highest possible deskew accuracy, without sacrificing speed.

LBitmap::ColoredPencilExt is a new smart artistic filter that produces a very realistic pencil stroke effect. The numerous parameter settings enable you to change the style so significantly that the results look like completely different filters.

Version 16 of this C++ Class Library has changed from version 15 as follows:

• For most functions, LEADTOOLS Version 16 now supports both ANSI and UNICODE development in the same libraries. For information on the required .dll file name and import library, refer to Files To Be Included With Your Application .

• LEADTOOLS now supports the following new vector file formats:

• File Formats: ArcInfo Interchange File Format (E00)

• File Formats: MapInfo Interchange File Format (MIF)

• LEADTOOLS has enhanced the following File format support to improve performance:

Raster

• ECW (Enhanced Compressed Wavelet): Now adds support for DPI and enhances performance.

• PDF (Portable Document Format): Enhances performance and add support for loading Pdf version 1.5/1.6, saving Pdf/A, saving Pdf with CMYK data, and saving Pdf version 1.4/1.5.

• PSD (PhotoShop 3.0): Enhances reading layers, masks, and alpha channels. Also it adds support for reading and writing Unicode layer.

• RTF (Rich Text Format): Now adds support for DPI and enhances performance.

• XPS (XML Paper Specification): Now adds support for DPI and enhances performance.

• J2K (JPEG and LEAD Compressed): Now adds new option to specify precinct size.

• ICA (IOCA/MO:DCA): Now adds support for saving IOCA files with ABIC compression with or without the MO:DCA wrapper.

Vector

• CMX (Corel Presentation Exchange): Now adds support for color/cmyk/Raster Image (RI Image).

• GBR (Gerber Format): Enhances files viewing.

• DWF (DWF Format): Enhances performance and adds Raster Image (RI Image).

• PCL (Printer Command Language): Adds support for margins and polygon modes. Enhances performance, text, and font manipulating, viewing for most accurate results, image support in filter, and saving PCL files.
