TIFF
Rendering
and
Conversion
RasterEdge Document Imaging SDK supports converting TIFF Document to various image or
document types with customized options. You can convert TIFF Document to PNG, JPEG, BMP,
and GIF image formats. You can also convert TIFF Document to SVG, which is a vector image
format that is supported by HTML5 standard and therefore supported by most of the up to date
web browsers. TIFF document can be converted to PDF file as well.
Convert
TIFF
Document
to
Image
Files
You can convert TIFF Document to a collection of image files with only one function.
void ConvertToImages(ImageType targetType,String directory, String fileName)
This method will automatically convert every page in the TIFF document to image file, with the
page index append to fileName. Note that, the resolution is default to be 96 dpi for monitor
displaying purpose. You can adjust to the resolution to enlarge the image dimension.
Convert
TIFFPage
to
Image
File
You can get specific TIFFPage object from tiff document by BasePage GetPage(int index). After
that you can render TIFFPage object to REImage or other common image formats with
customized parameters.
Related APIs:
REImage ConvertToImage()
REImage CropImage(Rectangle sourceRegion, Size targetSize)
void ConvertToImage(ImageType toType,String filePath)
For large TIFF images we recommend you to use CropImage API for methods with a REImage or
Bitamp object to return. It processes tiff images in partition. You can convert the image in parts
and then combine the partitions.

Convert
TIFFPage
to
Bitmap
In .Net framework Bitmap is a frequently used class in image processing. RasterEdge provide you
with APIs to directly convert TIFFPage to Bitmap objects which then can be drew on graphics of
for example win form controls. These APIs returning a Bitmap object are faster than return a
REImage object taking into account that some additional operations needed with REImage.
Bitmap GetBitmap()
Bitmap GetBitmap(float zoomValue)
Bitmap GetBitmap(Rectangle sourceRectangle, Size targetSize)
Note that the resulting Bitmap cannot be too big to handle due to the restriction of system
memory. You can divide the big page into parts and deal with them separately. Typically if an
original tiff image or the resulting image magnified has a dimension product over 3000*3000,
we recommend you deal with them in partitions.
Bitmap GetBitmap(Rectangle sourceRectangle, Size targetSize) is a good choose.
Draw(Graphics g, PointF loaction)
void Draw(Graphics g, PointF loaction, Size targetSize )

You can specify compression type using the following code. For example you want to generate a
Black and White tiff you should use CCITID compression. Please note that the default JPEG
compression will in most cases produce the best performance in speed

TIFF
Annotation
You can add annotations like text and highlight on TIFF page. For detailed information about
annotation objects, please refer to Annotation section.
You need the following dll(s) to implement this feature.

TIFF
Metadata
You can get the tag collection of the specific tiff page, which is comprised of EXIF Fields, TIFF
Fields and IPTC Fields. Every EXIF and TIFF Field is made up of a “tag”, a “dataType” and a
“values”. The IPTC field is made up of a“ID”, a “Section” and a “value”.

TIFF
Field
Assume you have retrieved the tag collection already, then you can edit the TIFF Field, we
provide 8 constructors to create a TIFF Field, and you can choose the field’s data type easily.
Note there are some important fields which can’t be removed. Otherwise the tiff file would be
corrupted. The TagID must be a hexadecimal.

s(
S
tri

ePa
t

}
Swap

pages
of
TIFF
File
You can swap two pages of the tiff file, suppose you have a TIFFDocument object already.
C#

You can also insert pages to TIFF document. Suppose you have a TIFFPage class object named
page, you can do something like this,
C#
pub

Split
TIFF
File
To split TIFF document, you can use TIFFDocument class. There is a static method called
SplitDocument, which takes either an input Stream or an input path, an input index and a list of
output paths or output Streams. For example, if the target file has eight pages and you input
two as the page index using SplitDocument, then the first three pages(index starts at 0) will be
included in one TIFF document and the rest of five pages will be included in the other TIFF file.

Combine
TIFF
File
Using TIFFDocument class, you can also combine TIFF documents. There is a static method
called Combine, which takes either an output Stream or an output path and any number of
input paths or input Streams. The input TIFF documents are combined in order to create one
output TIFF document.

Because in some cases you only need to show part of the image magnified, we provide you with
API to crop the TIFF image. This API costs fewer resources and less process time.
