	e_media : 0
	e_crop : 1
	e_bleed : 2
	e_trim : 3
	e_art : 4
}
Returns:
this object, for call chaining

Parameters:
Name Type Description
x1 number
y1 number
x2 number
y2 number
Returns:

Type
PDFNet.Convert.TiffOutputOptions

setGamma(gamma)

Sets the gamma factor used for anti-aliased rendering. Typical values are in the range from 0.1 to 3. Gamma correction can be used to improve the quality of anti-aliased image output and can (to some extent) decrease the appearance common anti-aliasing artifacts (such as pixel width lines between polygons). The default gamma is 0.
Parameters:
Name Type Description
gamma number
Returns:
this object, for call chaining
Type
PDFNet.Convert.TiffOutputOptions

setGray(enable)

Parameters:
Name Type Description
enable boolean
Returns:
this object, for call chaining
Type
PDFNet.Convert.TiffOutputOptions

setHRes(hres)

Sets the width of the output image, in pixels.
Parameters:
Name Type Description
hres number
Returns:
this object, for call chaining
Type

Parameters:
Name Type Description
mode number 
PDFNet.PDFRasterizer.OverprintPreviewMode = {
	e_op_off : 0
	e_op_on : 1
	e_op_pdfx_on : 2
}
Returns:
this object, for call chaining
Type
PDFNet.Convert.TiffOutputOptions

setPages(page_desc)

Specifies the list of pages to convert. "1" for only the first page. "1-5" for pages 1 to 5. "1, 5, 7" for pages 1, 5, and 7. "odd" for all odd pages. "even" for all even pages. By default, all pages are converted.
Parameters:
Name Type Description
page_desc string
Returns:
this object, for call chaining

setPalettized(enable)

Enabled the output of palettized TIFFs. This option is disabled by default.
Parameters:
Name Type Description
enable boolean
Returns:
this object, for call chaining
Type
PDFNet.Convert.TiffOutputOptions
