Rainbow PDF Server Based Converter V

Rainbow PDF Server Based Converter V3.0 outputs SVG that is compliant to W3C Scalable Vector Graphics (SVG) 1.1 specification. Moreover, it also outputs SVG Tiny and SVG Basic in the Mobile SVG Profiles.

SVG Output Format

Rainbow PDF Server Based Converter V3.0 can output any of the SVG 1.1, SVG Basic and SVG Tiny. When a profile is not specified, it is regarded as SVG 1.1.

Mobile SVG Profiles are the specifications for mobile computing devices or cellular phones which have restrictions in the throughput of the hardware, the memory capacity and the number of colors that can be displayed.

Since SVG Tiny is for the hardware with the most restrictions, like a cellular phone, the supported elements and attributes are quite limited. Therefore, the reproduction level of the original document may be low.

SVG Basic is for more high-efficient pocket devices, such as high-efficient PDA, and has fewer restrictions than SVG Tiny. See also Mobile SVG Profiles for more details.

Rainbow PDF Server Based Converter V3.0 outputs SVG Tiny and SVG Basic on the basis of the output for SVG 1.1 by disregarding the unsupported elements.

When the document composed of multiple pages is converted into SVG, each page will be output to each file. It is possible to output them collectively to one file by setting Command-line Interface etc. However, when it is output as standard out, it is always output to one file.

Image Output

Vector Images

The following vector images are outputted to SVG as vector primitives are replaced with SVG operators.

Raster Images

In SVG output, whether to embed the raster image into SVG or to output it to another file and link can be specified by Command-line Interface etc.
The raster image which can be embedded directly into SVG is as follows.

JPEG
PNG

The raster images put on the MS Office document are stored in some different types. In Rainbow PDF Server Based Converter V3.0, when the image is the format which can be embedded directly into SVG, the image extracted from the original document is embedded. when it is not so, it is embedded after converting into JPEG or PNG. An error occurs when there is an image of the format that cannot be converted. The image of the format not to be able to be converted occurs an error.

Font Output

Please refer to "Fonts" for the font.

With SVG Output, although the font can be embedded, the font file is not embedded but the stroke of the associated character of a font is embedded. Therefore, you cannot embed the font in SVG when the font is protected by the patent and its stroke cannot be acquired.
In addition, the correct outline might not be embedded with some of TrueType and OpenType fonts.

Restrictions

Images are transformed into a format that can be embedded directly in the SVG. Images whose format cannot be converted cause errors. See also Graphics for the supported image formats.

SVG Tiny

In SVG Tiny, since many elements are not supported, it may be difficult to reproduce output that is faithful to the original document. Rainbow PDF Server Based Converter V3.0 approximate the original as much as possible by substituting the elements with alternative expressions to the extent possible. The following are the main restrictions of SVG Tiny.

An MS Office document may contain hidden data that will appear in the SVG Tiny output. An example of this is data that is hidden by an image in the Office document will appear in SVG Tiny because clipping is not supported by SVG Tiny.
SVG Tiny does not support fills that contain gradation. Plain color is used as a substitutes.
Writing mode is not supported by SVG Tiny. When a document contains vertical writing, the position for every character will be specified. For this reason, the size of the document may become larger than the one outputted by SVG 1.1.
Many SVG Tiny viewers do not support the rotation of characters. Those viewers will ignore the rotated character, even the rotated characters in the original MS Office document are output with rotated attribute.
