Understanding Image Derivatives

Summary

Creating a derivative assists users in maximizing efficiency. With Derivatives all the variations and image modifications are made in your Bynder portal during upload.  Bynder Admins can even set up permissions to allow users to download derivatives, including watermarked derivatives.

Dynamic Asset Transformations (DAT) give you even more flexibility. Instead of setting up predefined derivatives, you can create digital asset transformations on the fly. 

Users can even have derivatives made automatically, simply contact your customer success contact to enable this time saving feature.  

Note: Both custom and default image derivatives cannot be created for files that exceed 25000 pixels in a single dimension (either width or height).

Understanding Default Image Derivative Dimensions

  • mini: 80x80 pixels

  • thul: 250x250 pixels

  • webimage: 800x600 pixels

Note: The resolution of your default derivatives may deviate slightly from the dimensions mentioned above depending on the aspect ratio of your original images.

Understanding Custom Image Derivative Options

Users can customize the resolution of the derivatives in the portal. When creating a derivative with custom resolution, Bynder uses the longer side to create the derivative. For example, an 800 by 600 pixels derivative will use the 800 pixel side is for resizing. The 600 pixel side is scaled according to the aspect ratio.

These custom derivatives can be set up in your portal:

  • A custom DPI value for your derivatives can be configured. For instance, we can automatically generate a 300 DPI derivative of your original 600 DPI image file.
  • An automatic crop generates the derivative based on the focal point of the image. The crop adjusts dynamically, ensuring that one of the longer sides of the desired aspect ratio reaches the image border while still outputting the required size.

  • Default dimensions and aspect ratio are preserved for use in your webshop. Bynder can resize the image according to the longer side and aspect ratio, and the remaining canvas size will be filled with a blank space to meet your fixed dimensions.
  • Derivatives generated based on the filename of the original file. Using regular expressions (regex) we can configure derivatives to only be generated when the filename of the original file meets specific criteria.  For example, if you don't want a derivative to be generated when the filename of the original file contains an icon.

Note: If using the Mass Uploader, the asset's filename must start with the specified regex for the derivative to be created. The standard uploader does not have this requirement.

  • Unique URLs can be generated for each derivative.
  • Accepted output formats (JPG, PNG, and TIFF) are used to generate the derivative file.
  • Recommended sizes: We recommend your asset have the original size, large(JPG - 1024*786 - 300 DPI - RGB), and small (JPG - 640*480 - 72 DPI - RGB).
  • Color spaces (RGB/CMYK/inherit): 
    • The inherit option ensures that the embedded color profile in the uploaded file is used to generate the derivative. This way, the derivative will be generated with the right colors. Inheriting the color profile is the best way to make sure that the color profile of the derivative will be identical to the color profile of the original file. If you want to make use of this option, make sure that you upload files that have an embedded color profile.
    • If no embedded color profile is available in the uploaded file, the system will fall back to a default color profile. For the RGB color space, this will be the sRGB color profile. For the CMYK color space, users can set a custom fallback color profile for you. If no custom fallback profile has been set up, the system will default to the ISO Coated v2 300% (ECI) profile. 
    • PNG derivatives can be customized to preserve transparency, and JPGs can define the desired quality.

Note: Aside from Vector files, Bynder can not create derivatives with larger dimensions than the original file as it would lead to quality loss.

Considerations

  • AI and PDF

    Bynder supports RGB derivatives for AI and PDF files. CMYK derivatives or derivatives that inherit the color profile of the original file cannot be created when the original file is an AI or PDF file.

  • DNG

    We cannot create derivatives for a DNG file if the original DNG file does not contain a preview file. Derivatives are based on the preview file only.

  • TIFF When the original file is a TIFF file the transparency cannot be preserved if:

    • The file includes transparent clipping paths, which often occur when the TIFF file is saved in Adobe Photoshop.

    • The TIFF file contains more than one alpha channel or a custom alpha channel.

    • The ExtraSamples metadata field of the TIFF file contains an unsupported value such as Unspecified. Only one of the following two values is supported:

Level: Proficient

Proficient-level articles are for users who have some prior Bynder knowledge. These articles require you to know the basics and may also require higher-level portal rights to accomplish the task outlined within the article.
