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 Enumeration.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.
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.
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.
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.
