File Content Extraction 26.1
XML Export SDK C Programming Guide

# Convert Presentation Files

Export has special configuration options that allow greater control over the conversion of presentation files.

## Convert Presentation Files to Raster Images

Export allows you to convert each slide in a presentation document to a raster image, providing a high-fidelity conversion of the document.

The output format depends on the value of `bRasterizeFiles` in KVXMLOptions. See KVXMLOptions.

## Convert Presentation Files to a Logical Reading Order

Some presentation files do not store the logical structure of the original document—the correct reading order, for example, and the presence and meaning of significant elements such as headers, footers, columns, tables, and so on.

In general, when you convert a presentation slide to a raster image, the output file retains the logical reading order because it uses the correct coordinates for each element in the output. However, if you do not use the `bRasterizeFiles` option in KVXMLOptions to produce a raster image, you might find that the export process generates output for some files that does not match the logical reading order.

When you do not want to rasterize your presentation files, you can use the `formats_e.ini` file to retain the logical reading order in your files.

The `formats_e.ini` file is in the directory `install\OS\bin`, where `install` is the path name of the Export installation directory and `OS` is the name of the operating system.

To enable logical reading order by using the formats_e.ini file

- In the `formats_e.ini` file, find the `[Options]` section, and set `LogicalOrder` to 1.

  For example:

      [Options]
      LogicalOrder=1

## Mitigate Text Wrapping

When File Content Extraction cannot render text in exactly the same way as in the original presentation (for example because exact font information is not available), the text might end up too large for the box that contains it. In this case, it might clip at the box edge, or overwrite other text.

To mitigate this effect, you can use the `GraphicFontScale` option to reduce the size of all text rendered to images by a certain amount.

NOTE: The `GraphicFontScale` option is available only on certain platforms (see GraphicFontScale option in the platform differences section).

The default value is 1. You can set it to a value between 0.01 and 100.0 to scale the text rendered into images by this amount. Setting `GraphicFontScale` to slightly less than one can help prevent truncation and wrapping when File Content Extraction does not have access to exactly the correct font. For example:

    [Options]
    GraphicFontScale=0.95
