Thanks snibgo.

Could I just get a yes/no answer as to whether or not exr support is something I can add without having to compile IM. I'm guessing not, but there has been enough ambiguity in the replies to make me ask once more.

If I just run (as in your example): convert a.png a.exr Where a.png is a valid .png file that I have saved out of Photoshop I get no errors, however the output .exr file is still a .png it's just been renamed .exr Perhaps ...

I have just downloaded and installed ImageMagick-6.8.5-Q16 When I try to convert any .exr files, I get this error: "convert.exe: no decode delegate for this image format" `_tile_5x17_20x20_render.1.exr' @ error/constitute.c/ReadImage/550. and it does not show EXR or OpenEXR when I run: indentify ...

Thanks, can you tell me if you see .exr listed when you run:

Hi all, I've recently been exploring ways to quickly and easily combine tiled half-float .exr renders with a simple lightweight command line based tool approach. I have access to Nuke and various other compositing solutions however taking a license from another user for this seems like overkill for ...
