Hi Jason, Sorry that we didn't get back to you sooner. We did review your proposal.
We think you were describing an API for accessing image meta-data as though it were an XML document. Were you proposing a SAX like API? Here is some review details from our dev. "SAX from what I little understand is pretty heavy weight API, and I think the QXmlStream classes are better suited to most people's requirements. I imagine what the proposed API would also be overkill for most people. XML isn't a bad analogue for meta-data (XMP for example is XML) but it only addresses the problem of parsing the meta-data, interpreting the data may still require knowledge of the underlying format." It seems your proposal to extend this API to include actual decoding of an image in a pieces or streaming of the decoded data would be beneficial by avoiding memory allocation for an entire image if it's not needed. At this point, our conclusion is that your needs are reasonable but perhaps not appropriate for Qt without additional functionality. It doesn't make much sense to us to re-invent image loading to be more suitable for image processing without having any image processing functionality. Meta-data may warrant two API one for well understood data (tags, gps data) and another for the more generic access you were describing.

Has anyone given it any thought? Were my ideas rejected? Did they seem interesting but need more explanation? _______________________________________________ Qt-mobility-feedback mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt-mobility-feedback _______________________________________________ Qt-mobility-feedback mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt-mobility-feedback
