README
redcap-em-image-viewer
This external module permits you to preview the contents of a file_upload field. It supports images and PDFs.
It should probably be called 'upload preview' but that's not for today…
Directions
- New: PDF files are now supported.
- Enable the module on your server. If you wish to enable some logging, there is a server-setting to specify a log path.
- Enable the module on a particular project that contains file-upload fields that you wish to use with preview
- Use the module configuration tool to select the preview fields
- Alternately, you can use the @IMAGEVIEW action tag to specify fields to be previewed by editing the data dictinoary directly.
- Each field can be supplied with CSS paramaters to control formatting. For example, on a PDF upload field you might add a parameter of
`{ "height": "400px" }`.
- If you are supplying custom formatting using the action tag, the format is:
`@IMAGEVIEW={"height":"500px"}`
- The format of the parameter string must be valid JSON (see https://jsonlint.com/ )
- In some cases, you might not be able to override the formatting if the parent table is constraining you
- If custom formatting is supplied both in an action tag and as part of the EM config page, the EM config page will take precedence
- The default size is to expand to the maximum width of the current table cell.
- For right-vertical (Default) this means upto 50% but less if the image is smaller
- For left-vertical alignment this means the full width of the cell
Example
Last tested on v7.6.9
