ImageGear Filter Control Parameters

Filter Control Parameter	Type	Default Value	Available Values	Description
DefaultCompression	ImGearCompressions Enumeration	ImGearCompressions Enumeration.NONE	Any ImGearCompressions Enumeration value	This parameter specifies a compression used for encoding a raster page added/inserted into the PDF document by using ImGearDocument.Pages method.
Depth	Int32	24	1, 8, 24	This parameter specifies bit depth in bits-per-pixel during the PDF document conversion into the raster image. The greater this value, the higher the quality of the raster image you get and the more memory required for rasterization. The DIB of the output raster image has this value as a bit count.
DrawMode	ImGearPDFPageDrawMode enumeration	ImGearPDFPageDrawMode.ENTIRE_PAGE	One of the ImGearPDFPageDrawMode enumeration values	This parameter specifies default PDF rendering method used by the ImageGear PDF component to draw PDF page content. To improve performance when scrolling in PDF documents you can change the DrawMode to ImGearPDFPageDrawMode.VISIBLE_AREA.
IndependentPagesize	Bool	false	true, false	If this parameter is false, when saving a raster image into the PDF document, the width and height of the newly created page is set to the width and height of the previous page from the PDF document. If the previous page does not exist, the width and height are calculated from the image resolution and size as follows: Width = <width of the raster image> * 72 / <X DPI of the raster image> Height = < height of the raster image> * 72 / <Y DPI of the raster image> If the image resolution is not defined, the width and height are set to the width and height of the Letter page, which is 612 x 792. If this parameter is true, the following parameters are used to set the page size: PageHeight PageWidth
IncRend	Bool	False	True, False	This parameter specifies the way of drawing rendering. The true value sets incremental (stripe by stripe) rendering mode, the false value sets rendering as a single bitmap.
PageHeight	Int32	0	Any non-negative value	This parameter sets the height of the page (in 1/72 inches). If this option is 0, the height is calculated from the image resolution and size as follows: Height = < height of the raster image> * 72 / <Y DPI of the raster image> If the image resolution is not defined, the height is set to the height of the Letter page, which is 792. This parameter is not used if IndependentPagesize is false.
PageWidth	Int32	0	Any non-negative value	This parameter sets the width of the page (in 1/72 inches). If this option is 0, the width is calculated from the image resolution and size as follows: Width = <width of the raster image> * 72 / <X DPI of the raster image> If the image resolution is not defined, the width is set to the width of the Letter page, which is 612. This parameter is not used if IndependentPagesize is false.
Password	String	""	Any string	This parameter specifies password string for password protected PDF documents.
PrintDepth	Int32	8	1, 8, 24	This parameter specifies bit depth in bits-per-pixel during the PDF document printing. The greater this value, the higher the quality of the raster image you get and the more memory required for printing.
PrintResolutionX	Int32	300	Any	This parameter specifies the horizontal resolution in dots-per-inch during PDF document printing. The greater this value, the higher the quality of the printed image.
PrintResolutionY	Int32	300	Any	This parameter specifies the vertical resolution in dots per inch during the PDF document printing. The more this value the more quality image is printed.
Resolution3D	UInt	72	Any, except zero	This parameter specifies the resolution in dots per inch used for generating a pre-rendered bitmap of the default view of the 3D artwork. Producers should provide bitmaps of appropriate resolution for all intended uses of the document; i.e., a high-resolution bitmap for high-quality printing, and a default screen-resolution bitmap for on-screen viewing.
ResolutionX	Int32	72	Any	This parameter specifies the horizontal resolution in dots-per-inch during the PDF document conversion into a raster image. The greater this value, the higher the quality of the raster image you get after rasterization. The DIB of the output raster image has this value as an X resolution.
ResolutionY	Int32	72	Any	This parameter specifies the vertical resolution in dots-per-inch during the PDF document conversion into the raster image. The greater this value, the higher the quality of the raster image you get after rasterization. The DIB of the output raster image has this value as an Y resolution.
SaveFlags	ImGearPDFSaveFlags Enumeration	ImGearPDFSaveFlags Enumeration.FULL | ImGearPDFSaveFlags Enumeration.COLLECT_GARBAGE	A bit composition of an OR of ImGearPDFSaveFlags Enumeration values	This parameter specifies an option for saving a PDF file, which allows you to remove unreferenced objects, often reducing file size as well as to write a linearized file for page-served remote (network) access, and to control compression of content streams inside a PDF file.
SaveMajor	Int32	0	1	Specifies major PDF version number of the document for saving. If major equals 0, both major and minor are ignored and the document is saved to the library's default version. Make sure that the document conforms to the version number you are setting.
SaveMinor	Int32	0	6, 5, 4, etc.	Specifies minor PDF version number of the document for saving. Make sure that the document conforms to the version number you are setting.
SmoothFlags	ImGearPDFSmoothFlags Enumeration	13 ImGearPDFSmoothFlags Enumeration.SMOOTH_IMAGE | ImGearPDFSmoothFlags Enumeration.SMOOTH_TEXT | ImGearPDFSmoothFlags Enumeration.ENHANCE_THIN_LINES	A bit composition of an OR of ImGearPDFSmoothFlags Enumeration values	This parameter specifies smooth settings for PDF rasterization.
SVGAcroformFeatures	ImGearPDFToSVGAcroformFeatures Enumeration	All	All, None, PushButton, RadioButton, Checkbox, Text, ComboBox, ListBox, Signature	When the conversion from PDF to SVG is performed the combinations of values of ImGearPDFToSVGAcroformFeatures defines the widget types that will be converted.
SVGAnnotationFeatures	ImGearPDFToSVGAnnotationFeatures Enumeration	All	All, None, FreeText, Line, Square, Circle, Polygon, PolyLine, Widget	When the conversion from PDF to SVG is performed the combinations of values of ImGearPDFToSVGAnnotationFeatures defines the annotation types that will be converted.
SVGBackgroundColor	ImGearRGBQuad	White	Any RGB color	Specifies the background color of the SVG file that has been converted from PDF.
TextEncoding	ImGearPDFTextEncoding Enumeration	ImGearPDFTextEncoding Enumeration.ASCII_85	Any ImGearPDFTextEncoding Enumeration value	This parameter specifies which encoding scheme should be used to convert binary image data to the text format when saving raster image into the PDF document.
XFAAllowed	Bool	false	true, false	Specifies whether to allow opening of PDF documents with embedded XFA content. true - PDF documents with XFA content will not throw an exception on opening. false - (default) PDF documents with XFA content will not open and will throw an exception. In order to enable opening of PDF documents containing XFA data, you must first add the PDF filter, then initialize the pdf engine, and finally set XFAAllowed to true. See XFA SupportXFA Support for more details. Form fields in documents containing XFA should not be modified. See also XFA Support for more information.
