Member Function Documentation

◆ create()

static JAWSMAKO_API IPSOutputPtr JawsMako::IPSOutput::create	(	const IJawsMakoPtr &	jawsMako,
		const IProgressMonitorPtr &	progressMonitor = IProgressMonitorPtr() )

static

Create a PS Output instance.

Parameters

jawsMako	The JawsMako instance.
progressMonitor	The progress monitor which allows aborting an operation or registering a progress callback.

◆ setAllowReusableImageStreams()

virtual void JawsMako::IPSOutput::setAllowReusableImageStreams ( bool allowReusableImageStreams )

pure virtual

Sets whether to allow reusable streams when writing images.

    When set to true, a single reusable stream (PostScript
    ReusableStreamDecode filter) will be used as the data source for any
    images that are considered to be reusable.

    This can produce significantly smaller output for content with lots
    of image reuse, but will increase the printer memory that is used.

    Currently, only color images will be considered for reuse.

    The default is false.

    Equivalent to calling setParameter() with the param name
    "AllowReusableImageStreams".

◆ setColorImageMaxResolution()

pure virtual

Set the desired maximum resolution, threshold and downsampling method for color images.

The default behaviour is leave the image resolution unchanged. Equivalent to calling setParameter() with the param names "ColorImageDownsamplingResolution", "ColorImageDownsamplingThreshold" and "ColorImageDownsamplingMethod" with the respective values.

Parameters

resolution	The desired output resolution, in dpi. Pass 0 to leave images unchanged, which is the default.

◆ setConvertAllObjectsToTargetColorSpace()

virtual void JawsMako::IPSOutput::setConvertAllObjectsToTargetColorSpace ( bool convert = true )

method	The method to use when downsampling. The default is bicubic for gray images.

◆ setJPEGQuality()

virtual void JawsMako::IPSOutput::setJPEGQuality ( uint8 quality )

pure virtual

Set the JPEG quality to use when compressing images in DCT format. Equivalent to calling setParameter() with the parameter name "JPEGQuality" and the value being the required quality. The default is 3 - normal quality.

Parameters

resolution	The desired output resolution, in dpi. Pass 0 to leave images unchanged, which is the default.
threshold	The threshold above which images will be reduced to the desired resolution. Pass 0 to use the resolution.
method	The method to use when downsampling. The default is subsample for monochrome images; using any other method will result in grayscale output.

◆ setPreferredColorImageCompression()

virtual void JawsMako::IPSOutput::setPreferredColorImageCompression ( eImageCompression compression )

pure virtual

Set the desired image compression for color images that need to be reencoded. The default is eICDCT.

CCITT is not allowed for color images.

Parameters

compression The desired compression.

Parameters

compression The desired compression.

◆ setPreferredMonoImageCompression()

Parameters

compression The desired compression.

◆ setStreamingOutput()

virtual void JawsMako::IPSOutput::setStreamingOutput ( bool enable = true )

pure virtual

Set whether or not streaming output should be enabled.

    Streaming output provides output as soon as it is ready, sending
    it to the output file or stream. Fonts are defined incrementally
    and a number of standard document structure comments are
    deferred to the end job trailer. This mode is suitable for use
    with streaming consumers, such as printers.

    If streaming output is set to false, then the output is withheld
    until the entire assembly has been processed. This enables
    providing all document resources (such as fonts and color
    spaces up front), and may be more useful for applications that
    further process the PostScript.
    The default is true.

    Equivalent to calling setParameter with the parameter name
    "StreamingOutput".

◆ setTargetColorSpace()

virtual void JawsMako::IPSOutput::setTargetColorSpace ( const IDOMColorSpacePtr & targetSpace )

pure virtual

Set the target color space for the intended output device. The default is DeviceCMYK. Equivalent to calling setParameter with the param name "TargetColorSpace" with appropriate values (please refer to documentation).

Parameters

targetSpace The desired color space. Must not be LAB, Indexed, DeviceN or scRGB. Any ICC space must have one, three, or four components.

◆ setTargetProfile()

virtual void JawsMako::IPSOutput::setTargetProfile ( const IDOMICCProfilePtr & profile )

pure virtual

Set the target color space for the intended output device using an ICC profile. Equivalent to calling setParameter() with the param name "TargetProfile" with the value as the path to the profile.

Parameters

profile The desired profile.
