We would require to have below functionalities in Thumbnail viewer in HTML/Javascript/React.
Multiple selection of thumbnails.
After multiple selection of thumbnails, we can delete it.
We can change the sequence of thumbnails.
We can select/drag multiple thumbnails and drop into different container to create a new PDF/Tiff file.
We can save file physically after doing all above operations.
We can show all thumbnails from single Tiff file.
We can show all thumbnails from single PDF file.
These functionalities is already available in Vintasoft Demo Windows Thumbnail Viewer but with few customization. We do not found this kind of Thumbnail viewer in HTML/Javascript/React.
Below are few snapshots:
Vintasoft demo Windows Thumbnail Viewer Demo
Sortable Thumbnail Viewer: To change sequence of thumbnails
Selectable Thumbnail Viewer: Multi select for drag & drop and delete multiple thumbnails
Let us know where we can find this kind of a control in HTML/Javascript, if it is not available then let us know how can we achieve this by Javascript/.NET Web API code (Basically we only require to loop all thumbnails from document and apply sort-able, drag-able/drop-able, multiple select-able, delete-able through Javascript code and later we will send all these data to server to process it to update the tiff file).
Do you need multiple selection of thumbnails using "mouse only", "keyboard only" or "mouse and keyboard" ?
Ans: Both, using "mouse" and "keyboard".
Do you want to delete selected thumbnails using keyboard ("Del" key) or mouse (context menu) ?
Ans: Both, using "Del" key and mouse "Context Menu".
Do you want to drag-and-drop thumbnails between different web thumbnail viewers ?
Ans: Here, we have two requirements as below:
1. Single thumbnail viewer to change the sequence though drag-and-drop, after doing we can save PDF/TIFF physically.
2. Another requirement is to Split the current PDF/TIFF through choosing different pages/thumbnails in multiple groups. Here we can able to do multi select via mouse or via keyboard. e.g. There are 9 pages of the PDF/TIFF file, now we want to Split this document into three files by choosing first 3 pages, second 3 pages and third 3 pages, to do, we just need to choose multiple thumbnails and after via mouse context menu we can add it into Split groups, see below snap shoot for reference:
