KnobMan, the VSTGUI AnimationKnob bitmap generator

[Leslie Sanford]

Hi g200kg.

Nevermind about my suggestion. I didn't describe it very well; plus, now that I think about it, I don't think it was a very good suggestion to begin with.

But I have another possibly weird request. I was wondering if it would be possible to have the option to export the images as 32 bit bitmaps; basically a bitmap in ARGB format. And if so, would it be possible to have an option to premultiply the RGB values with the alpha channel?

Basically, I'm trying to get away from GDI+, and I'm exploring other functions in Microsoft's API, such as AlphaBlend and others. It helps, at least in the case of AlphaBlend, to have 32 bitmaps with the alpha channel already premultiplied with the RGB values.

If this is too obscure of a request, I will completely understand.

Hi Leslie,

Have you tried using LibPNG ??

Hi Leslie,

Have you tried using LibPNG ??

Hi asseca, I haven't heard of LibPNG, but I will look into it.

I wrote a small utility program in C# yesterday that converts PNG files into 32-bit bitmap files with the RGB channels premultiplied with the alpha channel. So I'm good to go for now.

I will check out LibPNG to see what it has to offer, though. Thanks for the suggestion.

Firstly let me just say thank you to the dev for what is an utterly fantastic program. I can see that this is going to make my life so much easier.

I've encountered a problem however, and can't see anything for it in the documentation. I can't see how to make the knob bigger in the preview/render/test section. I know how to alter the size of it when it's exported, but not before that, and I can see that some of the examples are larger than mine, such as the aqua knob.

If anyone can help with this I'd be seriously grateful!

Thanks.

You mean when you press "set" in the left hand side options?

Hey RunBeer,

Sorry I forgot to respond to this. Thanks that was the problem! I wasn't pressing it; thank you for the help, sorted me out

Hm seems like you can't import your own designed knob in knobman or am I mistaking ?
I make my knobs /sliders in photoshop and want to animate and stitch them into one file ,
Can I import my own creations into knowbman ?

[Hlis93]

yes, select image from your primatives.

If you only want to join the images try PNGStitch for png files or Trentstitch for other image types. They make joining images much simpler than knobman.

[Hlis93]

+1 to png stitch. Also if you want after you use png stitch you can load those images into knobman with the image primative, the only catch is you will have to tell knobman if it vert or horz and the number of frames. I would also set the number of frame in the properties to the same as well.

Thank you for a GREAT tool. You rock the VST GUI world.

But as many others I have a request. Maybe it has been suggested before I dont know. Did not really read all 63 pages in this thread. But here we go:

-It would be great to be able to do mathematical scaling for the dynamic text. In example to show a correct dB scale.

so will this be further updated? any news? just curious...

[brok landers]

a small bump to keep upfront what deserves to be so...

I just found this tool, it's pretty amazing - and, you can run it in Linux through wine!

Maybe a bug: I accidentally set "Step" for primitive "V-Lines" to 0 (zero). The application hung indefinitely and had to be forcefully killed.

Wow! What a great tool. Thanks so much.

One question... is it possible to extend the size options beyond 200x200px? That's plenty big for knobs, but it would be helpful to have larger sizes for sliders.
