Changes from Version 17 to Version 17.5

Version 17.5 of this C++ Class Library has changed from version 17 as follows:

• LEADTOOLS now supports the HTML (Hypertext Markup Language) output for LEADTOOLS Document Writer SDK (C API or .NET).

Changes to options for rasterizing document formats

In LEADTOOLS 17.5, the RASTERIZEDOCOPTIONS structure is used exclusively to determine and calculate the page size, resolution and margins (rasterization) when loading document file formats that do not have physical size as a raster image. These file formats are listed in the table below:

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

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

Removed Functions

LSettings::UnlockSupport has been removed and replaced with LSettings::SetLicenseFile and LSettings::SetLicenseBuffer.

Changed Functions

LBitmap::GetHistogram: The type of pHisto parameter has been changed from L_UINT32 to L_UINT64.

LBitmap::AutoZone A flag has been added to uFlags (AUTOZONE_TEXT_DETECTION) that causes the function to modify the original bitmap so that all it contains is text. For this reason, if you set the flag be sure to make a copy of the original bitmap if you want to keep it.

RASTERIZEDOCOPTIONS bEnabled member was removed, see Changes to options for rasterizing document format below.

FILEPDFOPTIONS nXResolution and nYResolution members were removed, see Changes to options for rasterizing document format below.
