The ReadModuleType enumeration may take the following
The Default value allows ABCpdf to delegate the read operation
to what it considers to be an appropriate module or set of modules,
depending on the content provided and the method called.
The Pdf value is the standard PDF import module. It takes
advantage of the Password property.
The SwfVector module is a native Flash / SWF vector import
module. It takes advantage of the Operation and Frame
properties. The Operation must be either null or a SwfImportOperation.
The Xps module is a native XPS and OXPS (Open XPS) import
module. It takes advantage of the Operation property, which must be either null
or an XpsImportOperation.
The XpsAny module prints via the XPS printer driver and then
imports the resultant document. It takes advantage of the Operation, FileExtension, and Timeout properties. The Operation provided must
be either null or an XpsImportOperation.
The MSOffice module uses Microsoft Office for document
conversion. This module is fast and produces high fidelity output,
including native form fields and annotations conversion. It takes
advantage of the AddForms, Boomarks, Password,
The OpenOffice module uses OpenOffice.org for document
conversion. It takes advantage of the OpenOfficeParameters and Timeout properties.
The WordGlue module uses WordGlue .NET for DOC and DOCX
conversion. WordGlue .NET is a fully managed component for the
conversion of semantic document formats. This requires WordGlue
184.108.40.206 or later to be installed. WordGlue can be downloaded from
our web site.
The RichTextFormat module is a native RTF import module. It
takes advantage of the DefaultRect and Timeout properties.
The Svg module is a native SVG (Scaleable Vector Graphics)
import module. It takes advantage of the DefaultFont and DefaultRect properties.
The Eps module is a native EPS (Encapsulated PostScript) import
module. It takes advantage of the ErrorHandling and Log
The Tiff module is a native TIFF (Tagged Image File Format)
import module. It takes advantage of the PreserveTransparency and Frame properties. TIFF images may be black and
white, grayscale, RGB, CMYK, TIFF or Lab in 1, 8 , 16 and 32 bits
per component color depth and with out without alpha. Because PDF
does not support 32 bit High Dynamic Range (HDR) encodings, TIFFs
in this format will be downsampled to 16 bits per component. TIFF
images containing JPEG or CCITT compressed frames will be inserted
direct into the document without a decompress-recompress cycle.
This module is broadly similar in speed to System.Drawing for most
images. For CMYK images and images with large embedded color
profiles it is a bit slower simply because there is more data to
compress. In out tests with large images in the order of about 500
MB it was about ten times faster. In our tests with TIFF images
containing JPEG or CCITT frames it is typically about thirty times
The Photoshop module supports the standard PSD and also the
large image PDB file types. If the PreserveTransparency property is set
any transparency will be preserved. It allows the direct import of
bitmap, RGB, Grayscale, CMYK, Lab, Indexed and Duotone images in 1,
8 , 16 and 32 bits per component color depth, all with or without
alpha. The PDF format does not support 32 bits per component HDR
images so these are scaled down to 16 bits per component. The
Frame property allows the extraction of
individual layers from within the image. TIFF orientation flags are
automatically applied so that images that are tagged in this way
automatically appear the right way up.
The BasicImage module allows you to read images such as JPEG and
multi-page TIFF directly into a PDF document. It takes advantage of
