Feature-Request: Possibility to keep image's metadata #35
Description
I work together with professional photographers.
One of them just recently indicated, that the metadata (IPTC/EXIF/ICC) he puts in his images gets stripped away on his photos.
Every picture used by my clients gets resized in my chunks/snippets to best fit the browser/layouts needs.
And I tested it: when the original file is uploaded, and downloaded again, the metadata still exists. But when used in the frontend (and thus resized/optimized by my code), the metadata gets stripped away.
Would it be possible to add some options that allow a developer to choose to keep the metadata?
If this is not possible or not in the scope of Resizer: would it be possible to add a MODX-Event like OnResizerResize?
With such an event I could write a plugin that listens to it, and with the help of a library like pel, could copy the metadata from the original file to the newly created thumbnail.
