Image Output

Office Server Document Converter V7.1 supports the following types of image output: Monochrome/256 colors image output is only available for the Windows version.

In Windows version, Office Server Document Converter V7.1 creates bitmap images using the feature of Windows GDI or GDI+ features, and transforms them into associated image formats. The maximum size of a bitmap image depends on the system and the status of the available memory space. For this reason, the available maximum size of the image available is indefinite. If an error occurs (e.g. Rasterization error: xxxxx), please change the setting so the output size is smaller. When using GDI+, it must be specified. However, if it is specified in an environment where GDI+ cannot be used, it is processed without using GDI+ even if it's specified.

In Linux version, Office Server Document Converter V7.1 creates PDFs and converts PDFs into associated image formats. The maximum size of an image depends on the system and the status of the available memory space. For this reason, the available maximum size of the image available is indefinite.

Optional parameters of the output image

Parameter Functions
Smoothing processing Performs the smoothing when printing and outputting images. Specifies the smoothing processing to text, borders and images separately.
1.Text
2.Border
4.Image
Add values when you specify the smoothing processing in combination. If the value is omitted, "7" (all of 3 values are added) is automatically specified. This parameter is effective only with Windows 7 or later / Windows Server 2008 or later.
Output resolution Specifies the image size by a numerical value from 1-1,440 (DPI) when outputting an image. When the value of this parameter is outside the range or is omitted, a DPI value specified by the font size in the image is applied. (Windows version)
The maximum image size available to output depends on the Windows system resources such as free available memory, etc.
Reduction ratio The reduction ratio of an image output is specified by a numerical value greater than 0 but equal to or less than 1. It can also be specified by % or px (pixel) value. When the value of this parameter is outside the range or is omitted, the default is 1.
Maximum height Sets the maximum image height decided by the -rasscale parameter when outputting Images. "px" (pixel) is available as the unit.
File name format If the original document of the image output has multiple pages, multiple image files will be outputted with sequential numbers at the end of the file name. This parameter specifies the format of those sequential numbers. For example, when "document.png" is specified as the name for the output file, by specifying "-01" for -rasfmt, the output files will be document-01.png, document-02.png and so on. If this parameter is omitted, the default is "1".
Using GDI+ GdiPlus is used when the file is converted to Image. This setting is effective only with Windows 7 or later / Windows Server 2008 or later.
JPEG Quality Specifies the conversion accuracy by value within a range of 1-100 (%). When this parameter is omitted, the default is 80%.
Monochrome Output This parameter is specified when the original file is monochrome.The output in this format is only available for the Windows version.
Grayscale Output This parameter is specified when the original file is Grayscale.
256 color This parameter is specified when the original file is 256 color.The output in this format is only available for the Windows version.
