In previous versions of LEADTOOLS, the options to control the rasterization process have been consolidated into the CodecsRasterizeDocumentLoadOptions class and old class members were deprecated. In 17.5, these deprecated members are removed from the toolkit. The following table lists the removed members and their replacements:

Removed Member	Replacement
CodecsRasterizeDocumentLoadOptions.Enabled	None. This has been removed and CodecsRasterizeDocumentLoadOptions is always used when rasterization document files (the equivalent CodecsRasterizeDocumentLoadOptions.Enabled = true in previous versions of LEADTOOLS)
CodecsPdfLoadOptions.XResolution and CodecsPdfLoadOptions.YResolution	CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution
CodecsXpsLoadOptions.Resolution	CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution
CodecsTxtLoadOptions.LeftMargin, CodecsTxtLoadOptions.TopMargin, CodecsTxtLoadOptions.RightMargin, CodecsTxtLoadOptions.BottomMargin, CodecsTxtLoadOptions.PaperWidth and CodecsTxtLoadOptions.PaperHeight	CodecsRasterizeDocumentLoadOptions.LeftMargin, CodecsRasterizeDocumentLoadOptions.TopMargin, CodecsRasterizeDocumentLoadOptions.RightMargin, CodecsRasterizeDocumentLoadOptions.BottomMargin,
CodecsRtfLoadOptions.LeftMargin, CodecsRtfLoadOptions.TopMargin, CodecsRtfLoadOptions.RightMargin, CodecsRtfLoadOptions.BottomMargin, CodecsRtfLoadOptions.PaperWidth, CodecsRtfLoadOptions.PaperHeight, CodecsRtfLoadOptions.XResolution and CodecsRtfLoadOptions.YResolution	CodecsRasterizeDocumentLoadOptions.LeftMargin, CodecsRasterizeDocumentLoadOptions.TopMargin, CodecsRasterizeDocumentLoadOptions.RightMargin, CodecsRasterizeDocumentLoadOptions.BottomMargin, CodecsRasterizeDocumentLoadOptions.PageWidth, CodecsRasterizeDocumentLoadOptions.PageHeight, CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution

As well as the changes listed above, note that the following members contain updated default values:

Member	Old value	New value	Notes
CodecsRasterizeDocumentLoadOptions.XResolution and CodecsRasterizeDocumentLoadOptions.YResolution	0, 0	300, 300	In previous versions of LEADTOOLS, a value of 0 was used for these members to instruct the toolkit to load the documents using the current screen resolution. This proved to be not an optimal solution since the result document will almost always be loaded using a small resolution (such as 96 DPI) that is unsuitable for detailed viewing or OCRing. The new default of 300 by 300 DPI results in documents loaded at a higher detailed resolution.
CodecsPdfLoadOptions.DisplayDepth	24	0	In previous versions of LEADTOOLS, PDF documents were rasterized at 24 BPP by default regardless of the number of colors in the original document. The new default value of 0 instructs LEADTOOLS to auto-detect the best bits/pixel value to use when loading a PDF file, hence, a black/white PDF file will be loaded at 1BPP by default resulting in a much less memory being used.

In previous versions of LEADTOOLS, a value of 0 was used for these members to instruct the toolkit to load the documents using the current screen resolution. This proved to be not an optimal solution since the result document will almost always be loaded using a small resolution (such as 96 DPI) that is unsuitable for detailed viewing or OCRing.

The new default of 300 by 300 DPI results in documents loaded at a higher detailed resolution.

CodecsPdfLoadOptions.DisplayDepth

In previous versions of LEADTOOLS, PDF documents were rasterized at 24 BPP by default regardless of the number of colors in the original document. The new default value of 0 instructs LEADTOOLS to auto-detect the best bits/pixel value to use when loading a PDF file, hence, a black/white PDF file will be loaded at 1BPP by default resulting in a much less memory being used.

Version Changes: 16.5 to 17

Note on LEADTOOLS for .NET v17

In LEADTOOLS for .NET v16.5, some assemblies had a dependency on System.Drawing. System.Drawing is the .NET 2.0 assembly used with the Windows Forms and GDI+ platforms. Since LEADTOOLS v17 treats Windows Forms and Windows Presentation Foundation (WPF) as equal citizens, certain types in this LEADTOOLS assembly have been changed to reflect that. For example, properties with System.Drawing.Point type have been changed to use the new Leadtools.LeadPoint type, methods with a parameter of System.Drawing.Rectangle type have been changed to use the new Leadtools.LeadRect type. The following table shows the old 16.5 and corresponding new v17 types:

Old v16.5 Type	New v17 Type
System.Drawing.Point	Leadtools.LeadPoint
System.Drawing.Size	Leadtools.LeadSize
System.Drawing.Rectangle	Leadtools.LeadRect
System.Drawing.Color	Leadtools.RasterColor
System.Drawing.Drawing2.FillMode	Leadtools.LeadFillMode

These changes are not listed in the topics below.

Enhanced Features

LEADTOOLS version 16.5 includesJPEG2000 and JPEG support enhancements to improve performance compared to version 16.0 as follows:

JPEG2000 lossy decoder is 300 percent faster.
JPEG2000 lossless decoder is 10 percent faster.
JPEG2000 decoder uses MMX/SSD instructions by default. (To disable this feature and use floating point arithmetic, use either LOADFILEOPTION::Flags ELO_DISABLEP3 or LOADFILEOPTION::Flags = ELO_DISABLEMMX flags.)
JPEG lossless encoder and decoder are about 300 percent faster for RGB24 bitmaps.
JPEG lossless encoder and decoder are about 25 - 50 percent faster for Gray 8-bit, 12-bit and 16-bit bitmaps.
