Verve Levels bug

Hi Taron,
I did my study of "Hans Holbein the Younger, Portrait of Henry VIII" on Verve_painter v0.99v.18a.exe
but opened it on Verve_painter v0.99w.08 to adjust its Levels
and it changed the Levels fine the first time, so I kept working on the artwork on Verve_painter v0.99v.18a.exe,
but somehow now when I open it again on Verve_painter v0.99w.08 and try to adjust the Levels I get a black image,
but even this early version of the artwork (showing in the img) gives the same black image when trying to apply Levels,
and in that early version I didn't apply levels at all, I guess I resized the canvas, or applyed warp. Can any of those make the Levels to not work properly?

Can I do something to get the Levels working again?

Many thanks in advance Taron.

That's a weird one... I would have to see the image to judge what's happening there. Can you send it to me? Dropbox or so? Or email?
If you only drew with one color and it's all alpha, levels shouldn't do anything. If you primed the canvas and painted on top of that, then levels should work fine, but if it's something else...well... I really would have to look at it.
I haven't encountered any bugs with levels, yet, so... it's probably not so much a bug, but something unexpected.

Thanks for the reply Taron

If you only drew with one color and it's all alpha, levels shouldn't do anything

they did, Levels on an alpha drawing, change the value of the drawing. I sent you an email with a very short video about it and also the file as you requested.

Thanks Advanced.

Yaha, of course, I mean... you can lift or drop the color value, but it does not affect the alpha. That's what I tried to say.
I will examine your project! Thanks for the email!

HA!
Wow... I know what the problem IS and it is my stupidity, BUT I know how you can solve it before I will solve it, haha.
Somehow, totally black freaks out my levels.
Just go to RED channel, for example, and give the bottom a tiny nudge and all will be well again. I'll solve it for the next release, I promise!

Many thanks Taron.
I'm happy to with my tiny collaboration of today for a future Verve pro release.

[Taron]

And me! That's awesome, Eduardo!

Though, by doing that indeed get the image well again, but also the Levels will not adjust the brightness of the drawing (black lines and shades) anymore.

[Taron]

Pick up RED, GREEN and BLUE to some good amount and then you should be able to adjust from there. It's about 0 values. Not sure how I messed this up, but I will fix it, of course.

many thanks Taron
