Re: [Openexr-devel] Surviving partial-saved exr tiles

[Florian Kainz]

Hi Ton,

incomplete tile-based files should be readable.  When you attempt
to read a missing tile an exception is thrown, but you should be
able to continue reading after you have caught the exception:

    for (int tileY = 0; tileY < in.numYTiles(); ++tileY)
        for (int tileX = 0; tileX < in.numXTiles(); ++tileX)
            try
            {
                in.readTile (tileX, tileY);
            }
            catch (Iex::InputExc &)
            {
                continue;
            }

Do you have an example file where continuing to read after a
missing tile does not work?

P.S.: I did reply to one or two recent mails from you, but my
mails directly to you all bounced.
