Assets file format best practices assets-file-format-best-practices

AEM 6.4 has reached the end of extended support and this documentation is no longer updated. For further details, see our technical support periods. Find the supported versions here.

Experience Manager Assets supports many proprietary and third-party file format libraries to cater to diverse file support requirements of users. The supported Adobe libraries include, Adobe Camera Raw, Gibson, Adobe PDF Rasterizer, and Adobe InDesign Server. In addition, Assets supports third-party libraries, including ImageMagick, TwelveMonkeys, and so on.

For the supported file formats, see Assets supported formats.

Adobe Camera Raw library adobe-camera-raw-library

For optimal performance, Adobe recommends using Adobe Camera Raw library for:

  • RAW
  • DNG

The Adobe Camera Raw library supports CMYK color profile as input. However, it generates the output in RGB colorspace and supports output in JPEG format only. It does not retain the source file colorspace (for example CMYK) in the thumbnails.

For more information, see Camera Raw support in Assets.

Adobe PDF Rasterizer library adobe-pdf-rasterizer-library

For best results, Adobe recommends using the Adobe PDF Rasterizer library for the following files:

  • Heavy, content intensive PDF files
  • AI files with thumbnails not generated out of the box
  • For AI files with SPOT (PMS) colors

Thumbnails and previews generated using PDF Rasterizer are better in quality compared to out-of-the-box raster output. The Adobe PDF Rasterizer library does not support any color space conversion. Irrespective of the color space of the source PDF file, Adobe PDF Rasterizer generates RGB output only.

Adobe InDesign server adobe-indesign-cc-server

Adobe recommends that you use Adobe InDesign server to extract Adobe InDesign-specific renditions, such as IDML and HTML. For more information, see Adding Experience Manager assets as references in Adobe InDesign.

Dynamic Media dynamic-media

Dynamic Media generates and delivers multiple variations of rich content in real time through its global, scalable, and performance-optimized network. It serves interactive viewing experiences and streamlines the digital campaign management process. For details around enabling Dynamic Media, see Configuring Dynamic Media.

Currently, Dynamic Media can support videos up to 15 GB of content per file.

ImageMagick library imagemagick-library

Adobe recommends using the ImageMagick library in the following scenarios:

  • To generate thumbnail renditions for EPS files
  • To preserve image profile information
  • To preserve transparency
  • To process PSD and PSB files

To know how to set up the ImageMagic library in Experience Manager, see Using ImageMagick. For optimum usage, see Best Practices for Configuring ImageMagick.

Image Transcoding Library image-transcoding-library

The Adobe Imaging Transcoding Library is an image-processing solution that performs core image-handling functions, including image encoding, transcoding, resampling, resizing, and so on.

Imaging Transcoding library supports the following MIME types:

  • PNG (8 bit and 16 bit)
  • GIF
  • BMP
  • TIFF/Compressed TIFF (apart from 32 Bit Tiffs and PTiffs).
  • ICO
  • ICN

For details, see Imaging Transcoding Library.
