 The **PDF** format is an advanced and popular file format that allows a variety of content. Because of the complexity of the format, it is impractical for a lightweight SDK such as `Dynamic Web TWAIN` to have full support for it. Instead, `Dynamic Web TWAIN` supports the format in two ways
 
 * `Dynamic Web TWAIN` can read and write a pure-image-based **PDF** file; 
-* `Dynamic Web TWAIN` can use its [PDF Rasterizer module]({{site.indepth}}features/pdf.html) to rasterize almost any **PDF** file and convert its visible content into images so as to "read" it.

 ### Improvements
 
 - **Security enhancements**: updated third-party libraries to enhance security.
-- **Image rasterization logic**: when both [`ReaderOptions.renderOptions.maxWidth/ ReaderOptions.renderOptions.maxHeight and resolution`]({{ site.api }}interfaces.html/setreaderoptions) are set, if the dimensions of the rendered image exceed the maximum width and height, use the resolution applied during the image rendering process rather than the set resolution.

 - **New Dynamic Web TWAIN Service installation path for Windows**: moved installation out of `SysWOW64` and `System32` on Windows to prevent rare false positive antivirus scans.
   - New 64-bit system-wide installations: `C:\Program Files (x86)\Dynamsoft\Dynamic Web TWAIN Service 19`
