Hi:

I can, very quickly, report that there's something hinky, but I don't know the genesis yet. So far, the plugin seems to work well.

I can report that something is hinky with the KF7 DX emulation. Now...this may be something *like* the problem that affected the Voyage--where if you have an image that is > 50% of the width of the screen, but smaller than 100%, it will blow it up to full-width.

I tested an ePUB that I had handy. It had a few smaller images (a line and a copy of the Presidential seal) and then two that were larger. The plugin calculated the two larger images at 797px w, and 444px tall. (I confess a bit of whatever about this--the original image was 827x455, but, hey.)

On the Emulation, the Great Seal (set to display at 300px wide; original image is the same size, unlike the other, above), displays at what I believe it should. Ditto on the K2 Actual. All groovy.

But the larger images--the 797s--displayed at 100% of the width of the DX, which is wrong. The DX has a width of 824, and although 797 is close, it's not 100% of the width. Now, I can't tell you anything about the K2, because, (like a bloody idiot), it of course displayed full-width there, b/c the K2 is only 600px wide. DUH.

I think that maybe the DX has that (originally) Voyage image glitch. I'm going to have to make up an ePUB, that has gradually-increasing images, one per page, maybe, and test it. Or a sliding scale. Otherwise, given the limitation of the 600px on the K2, I'm going to be chasing my tail for a while. Coincidentally, the presidential seal image is half of the size--50%--of the K2 screen, so...it works. Of course, because...half.

In summation:

The plugin seems to work. Obviously, I need to keep testing.
The DX emulation MAY have a bug that makes it display certain images too large or full-screen.
I need to bracket-navigate what makes it blow up.
The Voyage had a similar issue; in KF8, the moment you made something 51%, it was full-screen.
I don't know if this is the same yet.

That's all I know thus far. Oh, William: nice plugin.
