Document Solutions Image Viewer

Important note: A Shift from ‘GrapeCity Documents' to ‘Document Solutions'

GrapeCity Documents has undergone a marketing rebranding and as a result, this 7.2.3 version is the last release under the old GrapeCity Documents product naming. Starting with version 7.2.4, the package will only be released using the new name @mescius/dsimageviewer. The new package provides the same functionality, ensures future enhancements, and is backwards compatible with the current package. It is highly recommended to update to the new package as soon as you can. Your existing licenses will continue to work with the new package.
