Constructor & Destructor Documentation

◆ JpegDevice() [1/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( )

Initializes a new instance of the JpegDevice class with default resolution and maximum quality.

◆ JpegDevice() [2/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( System::SharedPtr< Aspose::Pdf::Devices::Resolution resolution)

Initializes a new instance of the JpegDevice class.

Parameters
resolutionResolution for the result image file, see Resolution class.

◆ JpegDevice() [3/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( int32_t  quality)

Initializes a new instance of the JpegDevice class.

Parameters
qualitySpecifies the level of compression for an image. The range of useful values for the quality is from 0 to 100. The lower the number specified, the higher the compression and therefore the lower the quality of the image. Zero would give you the lowest quality image and 100 the highest.

◆ JpegDevice() [4/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( System::SharedPtr< Aspose::Pdf::Devices::Resolution resolution,
int32_t  quality 
)

Initializes a new instance of the JpegDevice class.

Parameters
resolutionResolution for the result image file, see Resolution class.
qualitySpecifies the level of compression for an image. The range of useful values for the quality is from 0 to 100. The lower the number specified, the higher the compression and therefore the lower the quality of the image. Zero would give you the lowest quality image and 100 the highest.

◆ JpegDevice() [5/10]

Parameters
widthImage output width.
heightImage output height.

◆ JpegDevice() [6/10]

)

Initializes a new instance of the JpegDevice class with provided page size, resolution and maximum quality.

Parameters
pageSizePage size of the output image.
resolutionResolution for the result image file, see Resolution class.

◆ JpegDevice() [9/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( int32_t  width,
int32_t  height,

)

Initializes a new instance of the JpegDevice class with provided image dimensions, resolution and quality.

Parameters
widthImage output width.
heightImage output height.
resolutionResolution for the result image file, see Resolution class.
qualitySpecifies the level of compression for an image. The range of useful values for the quality is from 0 to 100. The lower the number specified, the higher the compression and therefore the lower the quality of the image. Zero would give you the lowest quality image and 100 the highest.

◆ JpegDevice() [10/10]

ASPOSE_PDF_SHARED_API Aspose::Pdf::Devices::JpegDevice::JpegDevice ( System::SharedPtr< PageSize pageSize,
System::SharedPtr< Aspose::Pdf::Devices::Resolution resolution,
int32_t  quality 
)

Initializes a new instance of the JpegDevice class with provided page size, resolution and quality.

Parameters
pageSizePage size of the output image.
resolutionResolution for the result image file, see Resolution class.
qualitySpecifies the level of compression for an image. The range of useful values for the quality is from 0 to 100. The lower the number specified, the higher the compression and therefore the lower the quality of the image. Zero would give you the lowest quality image and 100 the highest.
