Mac: issue getting image data

[kwach]

Doing either native transfer or memory transfer I'm getting an error EXC_BAD_ACCESS (code=1, address=0x8bb4ff0)

src.imageMemXfer(imageMemXfer);

in this function

ReturnCode dsmPtr(Identity* dest, DataGroup dg, Dat dat, Msg msg, void* data) noexcept{
        assert(isValid());

        auto mgr = d()->m_mgr;
        return mgr->m_entry(&mgr->m_appId, dest, dg, dat, msg, data); //<--
    }

This is because

src.setupMemXfer(setupMemXfer);

returns Twpp::Success with (Twpp::SetupMemXfer) setupMemXfer = (m_minSize = 0, m_maxSize = 0, m_prefSize = 0)

Setting whatever (1024102410) in those params doesn't change a thing for me.

Native Xfer mode, as in example, does the same thing.

What other data can help identifying the issue?

Try setting CFBundleIconFile as advised here: https://stackoverflow.com/questions/4100619/how-can-i-figure-out-if-an-exc-bad-access-error-is-even-the-fault-of-my-code

It looks like TWAIN is a mess on Mac OS and Image Capture API is the way to go: https://stackoverflow.com/questions/4044622/what-is-the-state-of-twain-on-the-macintosh-today

Hi. Could you please check whether the issue is fixed for you, or still persists, with the current version? I am going to close this issue on 2017-11-02 if there is no activity.

I did abandon the Mac TWAIN interface all-together. I was not able to make it work.

Sorry. M.
