The parameters include the file type (such as PNG or JPG), compression, image quality, and gray scale. **Referenced by:** [`Image`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/Image.md), [`ImageCollection`](https://docs.datalogics.com/apdfl18/Java/APDFL18.0.5PlusP2e/class/ImageCollection.md) ## Constructors ### ImageSaveParams ```java com.datalogics.PDFL.ImageSaveParams.ImageSaveParams() ``` *constructor* Default parameters for saving an image to a file. ## Methods ### delete ```java synchronized void com.datalogics.PDFL.ImageSaveParams.delete(Boolean disposing) ``` *protected* **Parameters** - `disposing` (`Boolean`) **Returns:** `synchronized void` ### delete ```java synchronized void com.datalogics.PDFL.ImageSaveParams.delete() ``` **Returns:** `synchronized void` ### finalize ```java void com.datalogics.PDFL.ImageSaveParams.finalize() ``` *protected* **Returns:** `void` ### getCompression ```java CompressionCode com.datalogics.PDFL.ImageSaveParams.getCompression() ``` **Returns:** `CompressionCode` The compression code currently set. The default is CompressionCode.Default. Gets the type of compression to be used in saving the image to a file. ### getDisableAlphaChannelGeneration ```java boolean com.datalogics.PDFL.ImageSaveParams.getDisableAlphaChannelGeneration() ``` **Returns:** `boolean` true if alpha channel generation is disabled, false otherwise. Gets whether alpha channel generation is disabled for the output image. When false, RGB image data with a Mask will be combined as RGBA + Alpha Channel output (32-bit). When true, the Mask is not combined and the output is RGB (24-bit). This is only valid for TIFF and PNG output formats. ### getHalftoneGrayImages ```java boolean com.datalogics.PDFL.ImageSaveParams.getHalftoneGrayImages() ``` **Returns:** `boolean` true if halftone conversion is enabled, false otherwise. Gets whether grayscale images are converted to halftone. When true, converts 8bpc grayscale images to 1bpc (B/W) images using a 45 degree line screen set for 106lpi at 600dpi. Note this can only be set to true for an image of ColorSpace of DeviceGray. ### getJPEGQuality ```java int com.datalogics.PDFL.ImageSaveParams.getJPEGQuality() ``` **Returns:** `int` The JPEG quality value (0-100). The default is 0. Gets the quality of a JPEG output image. ### getMonochromeThreshold ```java short com.datalogics.PDFL.ImageSaveParams.getMonochromeThreshold() ``` **Returns:** `short` The monochrome threshold value (0-255). The default is 128. Gets the threshold for determining which bits are white or black for Monochrome output. Note: this is only valid for TIF Images using G3 or G4 compression and HalftoneGrayImages must be set to false. ### getRaiseExceptionIfNotUsableColor ```java boolean com.datalogics.PDFL.ImageSaveParams.getRaiseExceptionIfNotUsableColor() ``` **Returns:** `boolean` true if an exception will be raised for unsupported color formats, false otherwise. Gets whether an exception is raised if the image color format is not natively supported. When true, an exception will be raised if the image being saved is not in a format this graphic form can save natively. When false, the image will be automatically converted into a form that can be saved natively (generally DeviceRGB using the sRGB profile). ### getReverseGray ```java boolean com.datalogics.PDFL.ImageSaveParams.getReverseGray() ``` **Returns:** `boolean` true if the grayscale output will be reversed, false otherwise. Gets whether the GrayScale output is reversed. Note this is only valid for an image with a DeviceGray Colorspace. ### getTIFFBlackIsOne ```java boolean com.datalogics.PDFL.ImageSaveParams.getTIFFBlackIsOne() ``` **Returns:** `boolean` true if the TIFF image is photometrically reversed, false otherwise. Gets whether a TIFF file is photometrically reversed. Note this is only valid for a 1-bit TIFF image with a DeviceGray Colorspace. ### getTIFFByteOrder ```java TIFFByteOrder com.datalogics.PDFL.ImageSaveParams.getTIFFByteOrder() ``` **Returns:** `TIFFByteOrder` The current TIFF byte order setting. Gets the byte order used within the TIFF file. This is only valid for TIFF output. ### getTIFFCMYKAlpha ```java boolean com.datalogics.PDFL.ImageSaveParams.getTIFFCMYKAlpha() ``` **Returns:** `boolean` true if CMYK + Alpha channel TIFF output is enabled, false otherwise. Gets whether CMYK image data is combined with the Soft Mask in TIFF output. Note: This is only valid for CMYK image data which has a Soft Mask; the output will be 40-bit. ### getWriteSeparationColorsToTIFF ```java boolean com.datalogics.PDFL.ImageSaveParams.getWriteSeparationColorsToTIFF() ``` **Returns:** `boolean` true if separation colors are written to TIFF, false if converted to sRGB. Gets whether separation colors are written to TIFF using the Photoshop tag. When false, separation colors will be converted to their alternate color space and rendered as RGB. When true, separation colors are output using the TIFF Photoshop tag. ### setCompression ```java void com.datalogics.PDFL.ImageSaveParams.setCompression(CompressionCode compression) ``` **Parameters** - `compression` (`CompressionCode`): The compression code to use. **Returns:** `void` Sets the type of compression to be used in saving the image to a file.

Note: this is only valid for TIF Images using G3 or G4 compression and HalftoneGrayImages must be set to false. ### setRaiseExceptionIfNotUsableColor ```java void com.datalogics.PDFL.ImageSaveParams.setRaiseExceptionIfNotUsableColor(boolean RaiseExceptionIfNotUsableColor) ``` **Parameters** - `RaiseExceptionIfNotUsableColor` (`boolean`): true to raise an exception, false to auto-convert. **Returns:** `void` Sets whether an exception is raised if the image color format is not natively supported. The default value is false. ### setReverseGray ```java void com.datalogics.PDFL.ImageSaveParams.setReverseGray(boolean reversegray) ``` **Parameters** - `reversegray` (`boolean`): true to reverse the grayscale output. **Returns:** `void` Sets whether the GrayScale output is reversed.
