ABCpdf gets up close and personal! Because it goes Direct to
PDF™ it's incredibly fast. Because ABCpdf doesn't rely on any other
software it can be completely multithreaded without any unpleasant
ABCpdf is simple yet powerful. It's designed so you can get up
to speed and productive within ten minutes. Yet if you want fine
low-level control you can have that too with ABCpdf.
Create PDF documents from scratch or read and modify existing
PDF documents. Add pages from other documents for seamless joining,
insertion and stitching of multiple documents. Stream your
documents direct to your client web browser without going via the
disk. All up into the GB range and beyond. All with support up to
and including PDF 2.0 - ISO 32000-2:2017.
Import HTML / CSS pages from local or remote web sites. Placed
HTML support means your HTML can be treated just like any other
media - placed wherever you like on the page. Paged HTML support
allows you to flow your HTML from one area to another - across
pages or columns or both. Select between google Chrome style,
Firefox style and Internet Explorer style HTML rendering engines. A
vast range of options gives you full control over the HTML
rendering process and DOM. Different engines give you amazing
levels of compatibilities with associated technologies like HTML5,
CSS3, SVG, web fonts and Font Awesome, AJAX, WebGL and many
Render your PDF documents in a variety of formats. Output your
pages in raster formats like JPEG, GIF, TIFF, PSD, JPEG 2000, High
Efficiency Image File Format (HEIF), WebP, DDS or JPEG XR in any of
a variety of color spaces and bit depths. Alternatively choose
vector formats like EMF, EPS, XPS, SVG, HTML, DOCX, WebGL and SWF
(Flash) for specialist areas such as high resolution print work.
Control advanced rendering settings such as alpha, compression
type, multiple pages and different horizontal and vertical
resolutions. Validated against the Ghent PDF Output Suite 5.0.
Add virtually any graphic into your PDFs. ABCpdf supports JPEG,
GIF, TIFF, BMP, PNG, PSD, PSB, EXIF, WMF, EMF, JPEG 2000, JPEG XR,
High Efficiency Image File Format (HEIF), WebP, RAW, DDS, PS, EPS,
XPS, WPF, SVG and SWF (Flash) amongst others. Additionally you can
reference image data from multiple locations in your document -
great for inserting watermarks and other frequently used graphics.
ABCpdf is fully PostScript compatible.
Full support for the XML Paper Specification (XPS), Open XML
Paper Specification (OXPS) and for Encapsulated PostScript (EPS).
Microsoft XPS provides an alternative for page description and
document storage but it is not compatible with the de-facto PDF
standard. EPS is widely used in printing but often provides
compatibility headaches when it comes to interoperability with PDF.
ABCpdf supports full interoperability between Adobe PDF and
Microsoft XPS and EPS. Convert your PDF documents to XPS or EPS.
Convert your XPS or EPS documents to PDF. And our conversion
routines are carefully written to preserve the natural structure of
your source documents wherever possible. So this means the
preservation of color spaces and the preservation or conversion of
embedded fonts. Unless of course you want to change the format in
which case you can render directly to Grayscale, RGB or CMYK
Output, validation and conversion to PDF/A standards. Conversion
is made to work the way it should - it operates on practically all
documents - even documents provided by third parties. A partner in
this is transparency flattening which is a technology which allows
you to remove transparency from your documents while leaving the
vector nature of the format intact.
Full support for the Windows Presentation Foundation (WPF).
Microsoft WPF was the graphics sub-system originally developed for
.NET 3.0. Of course with a graphics API drawing to screen a PDF
export facility is needed too. As such ABCpdf comes with full WPF
import capability. See our WPFTable example project for details and
Not only does ABCpdf support PDF, HTML and Rich Text Format
(RTF) natively but it also supports a wide range of other document
formats. Formats like Microsoft Word (.doc), Microsoft Excel
(.xls), PowerPoint (.ppt), WordPerfect (.wpd), Lotus 1-2-3 (.wk1)
and AutoCAD (.dxf). All you need to do is read them in! *
ABCpdf allows you precise control over the way that your text is
laid out. Paragraph indent, kerning and tracking, word spacing,
line spacing, paragraph spacing and horizontal justification are
just some of the settings available. ABCpdf supports synthesized
bold and italic typeface styles for situations in which you do not
want to reference multiple typefaces.
ABCpdf supports Unicode and foreign languages. Reference fonts
from the relevant foreign language pack or embed Unicode fonts for
guaranteed fidelity of reproduction on any platform. Draw text
horizontally or vertically and quickly subset large CJK fonts with
minimal use of memory and impact on server load. Work with
bidirectional script such as Hebrew and contextual ligatures in
languages such as Arabic
Styled text allows easy creation and layout of multi-styled
text; supporting text box chaining to allow you to easily and
automatically flow text through from one area to another, around
images and other irregular objects. More complex options like text
on a curve or drop shadows are simple to implement using our
Apply advanced transformations like rotation, magnification,
skew and translation. This means you can draw rotated text, images
and graphics all with only a few simple commands.
ABCpdf allows multiple different approaches to layout and
document structure. The Table project shows how to use programmatic
table based layout. The WPF Table project shows how to take WPF
based content and convert it to PDF. The ABCpdf12.Drawing wrapper
namespace exists for easy porting of System.Drawing code for PDF
output. Or if you're more interested in XML to PDF or tagged PDF
output there are the Tagged PDF Example projects.
ABCpdf supports sophisticated color spaces. Mix and match RGB,
CMYK, Grayscale, Lab, calibrated color spaces and spot colors. Any
kind of graphic from text to lines to blocks of color can be drawn
in any of these color spaces. You can even perform complex
operations like colorizing grayscale images using spot colors or
converting from one color space to another.
ABCpdf supports direct import of ICC based RGB, CMYK and Lab
images from TIFF, PSD and PSB. Full TIFF and PSD support for all
color spaces, compression models and bit depths up to HDR
(High-dynamic-range). This means you can produce high-quality,
print-ready PDFs directly from your applications.
ABCpdf supports transparency everywhere. Any kind of graphic
from text to lines to blocks of color can be drawn transparently
using a simple alpha value to control levels of opacity. You can
apply soft masks or chromakey style masks to images for selective
transparency. Or you can draw transparent images such as GIF using
Create encrypted or signed PDFs for secure storage of PDF
documents. Apply user permissions and secure these permissions with
encryption keys from 40 to 128 bits in size. Check signed documents
for validity. Examine different revisions of documents to find
changes between them. Revert back to any previously saved revision
ABCpdf supports Fields and Forms. Use placeholder fields in your
template documents to position and lay out dynamically created
elements or assign field values directly. Stamp fields directly
into the PDF to prevent them being modified. Create new
annotations, anything from simple text fields through to multiple
incrementally updated signatures. With advanced support for exotic
for field calculations, triggers and callbacks.
Digital signature signing and verification using software,
hardware or cloud based certificates. Support for standards like
PAdES for standards compliant signatures - B for the base level, T
to add a timestamp, LT for long term archival and PAdES LTA for
extended long term archival.
ABCpdf now supports conversion of PDF content into annotated
SVG. This allows you to identify individual elements on a page and
map them back to the operators in the original PDF file. So it lets
you perform operations like search and replace on PDF text or
identify individual images on a page.
PDF optimization and size reduction provides whole document
optimization using a variety of options to reduce font sizes,
remove embedded fonts, to resample and recompress images, to
flatten wherever possible for the smallest possible output.
PDF analysis has been extended into easy-to-use operations for
text and images. Simple on the surface but sophisticated
underneath, they allow you to extract common-sense, de-hyphenated
and de-ligatured text from PDFs. Then select items of that text
within the PDF and perform operations on those selections.
If you have your own custom PDF analysis needs these can be
easily implemented using the content stream deconstruction APIs. So
if you want to separate out spot color graphics or change the width
of lines or indeed pretty much anything, there are simple classes
to allow you to achieve this.
PDF accessibility is now something that can be supported, even
for PDFs which were never designed to do so. Standards such as
PDF/UA and Section 508 compliance require that PDFs be accessible.
Our accessibility operation performs a sophisticated semantic
analysis of the document content and adds appropriate tagging
information to produce an accessible Tagged PDF output. This
includes features like headers, footers, tables, lists and
Our ABCpdfView sample application now demonstrates this and a
whole host of other ABCpdf features. It allows you to open, view
and print PDF documents. It lets you edit text and text styles
within the PDF. It allows you to insert, delete and re-order pages.
It allows you to watermark documents. PDFView comes with full
ABCpdf offers great control over images in PDFs. You can resize
them using a variety of sophisticated and high quality resampling
algorithms. You can assign new color spaces or convert them from
one color space to another. You can compress them in CCITT, JPEG,
Flate or JPEG 2000 format. You can resample them from one bit depth
to another. Determine size, resolution and placements using
sophisticated analysis operations.
ABCpdf is fully floating point for precise positioning of text,
line and other objects at a fractional point level. Variable
precision floating point support allows you to trade off precision
against legacy compatibility.
ABCpdf allows even more advanced control over any PDF object in
your document. If you can't see how to accomplish a task using our
simple to use methods then you can always access the raw PDF
structure directly. This is true both for the structure of the
document itself and also for any content streams held within that
structure. You can use the Atom classes to look at the very lowest
level of the data structures involved or you can the Element
classes which encompass the entire of the PDF 2.0 specification in
