+
+### grayscaleTransformationModes
+
+Specifies how grayscale transformations should be applied, including whether to process inverted grayscale images and the specific transformation mode to use.
+
+It is an array of 8 integers, where each integer represents a mode specified by the [`EnumGrayscaleTransformationMode`]({{ site.dcvb_java_api }}core/enum-grayscale-transformation-mode.html) enumeration.
+
+View the parameter reference page of <a href="{{ site.dcvb_parameters_reference }}image-parameter/grayscale-transformation-modes.html?product=ddn&repoType=core" target="_blank">`GrayscaleTransformationModes`</a> for more detail about grayscale transformation modes.
+
+### grayscaleEnhancementModes
+
+Specifies how to enhance the quality of the grayscale image.
+
+It is an array of 8 integers, where each integer represents a mode specified by the [`EnumGrayscaleEnhancementMode`]({{ site.dcvb_java_api }}core/enum-grayscale-enhancement-mode.html) enumeration.
+
+View the parameter reference page of <a href="{{ site.dcvb_parameters_reference }}image-parameter/grayscale-enhancement-modes.html?product=ddn&repoType=core" target="_blank">`GrayscaleEnhancementModes`</a> for more detail about grayscale enhancement modes.
+
+### colourMode
+
+Specifies the colour mode of the output image.
+
+It is a value of the [`EnumImageColourMode`]({{ site.ddn_java_api }}enum-image-colour-mode.html) enumeration.
+
+View the parameter reference page of <a href="{{ site.dcvb_parameters_reference }}document-normalizer-task-settings/colour-mode.html?product=ddn&repoType=core" target="_blank">`ColourMode`</a> for more detail about colour mode.
+
+**Default value**
+
+0, which means output image in colour mode.
+
+### pageSize
+
+Specifies the page size (width by height in pixels) of the normalized image.
+
+### brightness
+
+Specifies the brightness of the normalized image.
+
+**Value Range**
+
+[-100,100]
+
+**Default value**
+
+0
+
+### contrast
+
+Specifies the contrast of the normalized image.
+
+**Value Range**
+
+[-100,100]
+
+**Default value**
+
+0
+
+### maxThreadsInOneTask
+
+Specifies the maximum available threads count in one document normalization task.
+
+**Value Range**
+
+[1, 256]
+
+**Default value**
+
+4
+
+### scaleDownThreshold
+
+Specifies the threshold for the image shrinking.
+
+**Value Range**
+
+[512, 0x7fffffff]
+
+**Default Value**
+
+2300
+
+**Remarks**
+
+If the shorter edge size is larger than the given threshold value, the library will calculate the required height and width of the barcode image and shrink the image to that size before detection. Otherwise, the library will perform document detection on the original image.
+
+### minQuadrilateralAreaRatio
+
+Specifies the minimum ratio between the target quadrilateral area and the total image area. Only those exceeding this value will be output (measured in percentages).
+
+**Value Range**
+
+[0, 100]
+
+**Default Value**
+
+0, which means no limitation.
+
+### expectedDocumentsCount
+
+Specifies the number of documents expected to be detected.
+
+**Value Range**
+
+[0, 0x7fffffff]
+
+**Default Value**
+
+1.
