Version: ELN v4.x

Image Editing & Annotation

Overview​

As of version 1.5.0, images can be edited or annotated directly in the Chemotion ELN UI without an external editor.

Supported file formats

Editable file types are .png, .bmp, .tiff, .tif, .svg, .jpg and .jpeg.

The tif and tiff formats are converted to png format before annotation to be able to display them in the browser. The original image is preserved and remains unchanged.

Images in research plans that were created before version 1.5.0 cannot be edited at the moment.

Procedure​

  • Before editing an image, it must first be saved in order to make the necessary preparations on the server.
  • When the editor is started for the first time, the user is asked whether they want to save the settings and the history locally.
  • Previously placed elements can be edited subsequently. In addition, texts can be changed later on.
  • After editing the image, the corresponding element must be saved in order to permanently apply the changes and make them visible.

Availability​

Images can be edited in several places on the ELN:

  • In Research Plan (body)

  • In Research Plan (attachments)

  • In a Dataset:
