Graphics

Office Server Document Converter V10.0 supports the following types of graphics input. Unless otherwise noted they are supported across all platforms; Windows, Linux.
When graphic cormats cannot be embedded directly into the outputted PDF/SVG, they are converted into the format that can be embedded. An error occurs if the original document includes any unsupported graphics format. Specify "3" in -extlevel option if you want the program to ignore any unsupported graphics and continue processing.

When the specified image cannot be acquired because the image is not existent, etc., a substitute image will be displayed instead. However if the image is a background-image, a substitute image will not be displayed.

Supports Windows Bitmap. The content-type is “image/bmp”.

Supports JFIF (JPEG File Interchange Format). The content-type is “image/jpeg”.

Supports JPEG 2000 of the following format.

• JP2 (The content-type is “image/jp2”)

Supports PNG (Portable Network Graphics Format). The following restrictions currently exist:

• Alpha channel information is effective with PDF1.4 or later.
• 16-bit color depth image will be truncated to 8-bit depth.

The content-type is “image/png”.

Supports the TIFF files of TIFF Revision 6.0 specification.

• No Compression
• PackBits Compression
• Modified Huffman
• CCITT Group3 1D
• CCITT Group3 2D
• CCITT Group4
• JPEG Compression
• LZW Compression
• ZIP Compression

Supports the following color expression.

• Grayscale
• RGB
• CMYK
• YCbCr
• CIE L*a*b*

Restrictions:

• The following formats are not supported.
  • Tiled Image
  • Planar Configuration=2 (Planar format)
• A YCbCr image is transformed into an RGB image when outputting to PDF.
• Alpha channel information is effective with PDF1.4 or later.
• 16-bit color depth image will be truncated to 8-bit depth.
• All pages are converted when the original file is a multi page TIFF file. When multi page TIFF images are embedded in a document, only the first image in the TIFF file will be processed.
• Some parts of the TIFF extensions cannot be loaded properly.

The content-type is “image/tiff”.

Supports Graphics Interchange Format. The following restrictions currently exist:

• In the case of Animation GIFs containing multiple pages, only the first page is displayed.

The content-type is “image/gif”.

Supports Windows Metafile. The image quality is maintained by embedding the vector image in the PDF, SVG. The following restrictions currently exist:

• Only the horizontal value for the pen width can be used. If the value is 0.0, the drawing is not processed.
• The Bitmap specified for the brush is disregarded.
• The calculation of physical size may not correct.
• Clipping of Multiple rectangles is not supported.
• The raster operation is not supported. The original copied data is drawn as is.
• The function of clipping the characters is not supported.
• The background of the character is always transparent.
• The function of rotating the character from the baseline is not supported.

WMF in gzip file format is also supported. The content-type is “image/wmf”.

Supports Enhanced Metafile. The image quality is maintained by embedding the vector image in the PDF, SVG. The following restrictions currently exist:

• Only the horizontal value for the pen width can be used. If the value is 0.0, the drawing is not processed.
• The Bitmap specified for the brush is disregarded.
• The calculation of physical size may not be correct.
• The raster operation is not supported. The original copied data is drawn as is.
• The function of clipping the characters is not supported.
• The background of the character is always transparent.
• The function of rotating the character from the baseline is not supported.
• The function of clipping the bottom drawing is not supported.

EMF in gzip file format is also supported. The content-type is “image/emf”.

Supports Scalable Vector Graphics (SVG) 1.1. Office Server Document Converter V10.0 greatly enhances the display quality of SVG in PDF through a newly developed SVG native output engine. For more details, see “SVG Conformance”. SVG in gzip file format is also supported.

If the correct xmlns is described in the svg tag, it's counted as SVG. If not, it's not counted as SVG.

The typical content-type is "image/svg+xml".

Office Server Document Converter V10.0 Plus supports CGM defined in ISO/IEC 8632:1999 and WebCGM 2.0 defined in W3C.
If the CGM Option is installed, CGM graphic is embedded as vector graphic into the PDF without raster degradation.

About the CGM input function, see CGM Conformance page.
