[Collection Upload] previewFilter and loadImageMaxFileSize #72

Closed pjam closed 7 years ago

pjam commented 8 years ago

When using a preview filter, like one for creating a thumbnail, the option loadImageMaxFileSize should be tested against the result image, but always tests against the original image.

How can we fix that?

It is not possible to determine the size of the thumbnail before it's generated, but as far as I can see the purpose of this option is to prevent the generation of the thumbnail if the source image is to large. This is probably meant as protection: if somehow a image that't to large has been uploaded, the server is protected against large operations from generating the thumbnail.

So, the solution for your problem would probably be to determine a generic "shrink" factor which applies in your use case, and use that to calculate the maximum file size of the original image.
