Big file export issue

[infoterra001]

Hello,

We have developed a pair of import/export plug-ins in order to support a in-house format. For several reasons, which are not explained here, we had to develop import-export plugins instead of a single format plug-in. Our in house file format is designed for aerial and satellite images and supports very large files which can be above 100.000*100.000 pixels in size.

The import plug-in works fine with large images but, unfortunately, we cannot export these images because the export plug-in is grayed out in the drop down list when a large image is loaded. We have tried with several versions of Photoshop up to CS 6 but the problem remains. We haven't found any attributes in the export plug-in in order to indicate that it supports large images.

Has anyone got an idea ?

Thanks,

Bruno

Heh, we also seem to run into the same issue with our Geographic Imager plugin, when exporting georeferenced files that exceed in either height or width the 30000 pixel limit (yeah, a common case for aerial or satellite data). PS indeed disables the menu and I'm unaware about any workaround for it (I'd also love to know if there is one). What's more important though, is that Photoshop doesn't actually disable the export plugin in this case - you can still run it through scripts or actions. And this is why for us specifically this is not really a big deal, because we do provide access to all our functinality including Export via our own panel.

Here http://forums.adobe.com/thread/745904 Chris mentioned a PIPL property that was supposed to exist that limits the exported file size, but I think the overall conclusion was that it didn't make it to the release, so unless he or Tom enlighten us here about another magic property, there may be no better soultion to it.
