`New features`

Transformation of the modules and extension schema

This release introduces the revision of the modules and extensions to align them with business needs.

The new modules are as follows:

Table 1. New base modules and extension schema
Base Modules & their Extensions	Description
`Module.ImageFormats`	Allows to load/save all supported image formats (apart from PDF loading)
`Extension.ImageFormatsPdfInput`	Allows to load PDF files (rasterization or content loading)

`Module.Prepro`	Allows the use of preprocessing algorithms applicable to scanner images
`Extension.PreproCameraImage`	Allows the use of preprocessing algorithms applicable to camera images

`Module.Barcode`	Allows to detect 1D barcodes
`Extension.Barcode2D`	Allows to detect 2D barcodes
`Extension.BarcodeAdvanced`	Enables the use of a third-party barcode engine to increase detection accuracy

`Module.Ocr`	Allows character recognition for printed Latin languages (except Vietnamese), Cyrillic languages, Greek, and banking fonts (OCR-A, OCR-B, CMC7, and E13B Optical)
`Extension.OcrHebrew`	Allows the recognition of Hebrew
`Extension.OcrArabic`	Allows the recognition of Arabic and Farsi
`Extension.OcrHandwritten`	Allows the recognition of handwritten characters (boxed and script)
`Extension.OcrAsianExtra`	Allows the recognition of Chinese (Simplified and Traditional), Japanese, Korean, Vietnamese and Thai
`Extension.OcrJapaneseAdvanced`	Allows combination with a third-party OCR engine to improve speed performance without compromising recognition accuracy

`Module.DocumentOutput`	Allows to create all output formats (except hyper-compressed PDF)
`Extension.DocumentOutputHyperCompression`	Allows to create hyper-compressed PDFs using IRIS iHQC technology

Impact of changes

This transformation of the modules and their extensions has important consequences that you should be aware of. Read this section carefully!

Removed modules and extensions

As a result of the module and extension schema changes, some resources are no longer available. Refer to the Removed Resources section for more information.

Update of binaries requirements for ImageFormats module

Since the extensions for the jbig2 and jpeg2000 formats have been integrated into the ImageFormats module, you must now always deploy the following libraries (.dll, .so, or .dylib) when configuring this module:

idrsjpeg2k16
idrsjbig216

Compatibility of existing license keys

The previously delivered license keys are still valid for the new modules and extensions.

Here is the mapping table describing the keys you can use to configure the new modules and extensions:

Table 2. Mapping table for license keys
Base Modules & their Extensions	License Key
`Module.ImageFormats`	`IDRS_MODULE_IMAGE_FILE` license key
`Extension.ImageFormatsPdfInput`	`IDRS_FILE_EXTENSION_PDF` license key

`Module.Prepro`	`IDRS_MODULE_PREPRO` license key
`Extension.PreproCameraImage`	`IDRS_PREPRO_EXTENSION_MOBILE_CAPTURE` license key

`Module.Barcode`	`IDRS_MODULE_BARCODE` license key
`Extension.Barcode2D`	`IDRS_BARCODE_EXTENSION_PDF417`, `IDRS_BARCODE_EXTENSION_QRCODE` or `IDRS_BARCODE_EXTENSION_DATAMATRIX` license keys
`Extension.BarcodeAdvanced`	`IDRS_BARCODE_EXTENSION_ENGINE_EVO_I` license key

`Module.Ocr`	`IDRS_MODULE_OCR` license key
`Extension.OcrHebrew`	`IDRS_OCR_EXTENSION_HEBREW` license key
`Extension.OcrArabic`	`IDRS_OCR_EXTENSION_ARABIC` license key
`Extension.OcrHandwritten`	`IDRS_OCR_EXTENSION_HAND_WRITE` license key
`Extension.OcrAsianExtra`	`IDRS_OCR_EXTENSION_ASIAN2` license key
`Extension.OcrJapaneseAdvanced`	`IDRS_OCR_EXTENSION_ASIAN3` license key

`Module.DocumentOutput`	`IDRS_MODULE_DOCUMENT_OUTPUT` license key
`Extension.DocumentOutputHyperCompression`	`IDRS_DOCUMENT_OUTPUT_IHQC_EXTENSION` license key

Update of the Vietnamese and Thai recognition requirement

The extension Extension.OcrAsianExtra is now required for Vietnamese and Thai OCR.

If your iDRS integration does not have this extension, please contact your account manager to verify that you have the right to access it.

`Improvements`

Blank page detection

Blank page detection is improved by the following 2 points:

The 'Sensitivity' property of CBlankPageDetection is transformed into an enum range so that the effect of this property is more obvious: from BlankPageDetectionSensitivity.StronglyFavorBlank to BlankPageDetectionSensitivity.StronglyFavorNotBlank.
The advanced mode algorithm BlankPageDetectionMode.Advanced is also improved to give more weight to the selected sensitivity. The default sensitivity BlankPageDetectionSensitivity.Balanced remains the setting that is expected to give the best results overall.

Improved PNG saving speed when performance is favored over file size

PNG file saving speed is improved when performance is given priority over file size.

The compression levels affected are CompressionLevel.MaximumPerformance, CompressionLevel.VeryHighPerformance and CompressionLevel.HighPerformance. The other values are not affected by this improvement.

For the compression levels concerned, the PNG file created is slightly larger, but the creation time is much faster (up to 2 times faster for CompressionLevel.MaximumPerformance).

`Deprecated or removed resources`

Removed modules and extensions

Due to the transformation mentioned above, some extensions and one module have been removed:

Before Now
