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.

Yes, you can enter the value with the keyboard.

KnobMan ver 1.35 is released

http://www.g200kg.com/en/software/knobman.html

What's new in 1.35
* Scrollable effect pane
* Accurate color mix at Primitive edge
* New color selector window
* Preview image dragging for test
* Text primitive formula support (including log/log10/exp/pow/sqrt)

Preview Dragging will ease the confirmation how looks the knob on background.

Text primitive formula, for example, the text (0

%.2f:10*pow(100,x/100)) will make exponential curve.

Thank you

when you say this, do you mean it includes gamma correction?

does it include gamma correction for re-sampling? (when you do 1/4 scaling, is data gamma corrected before/after averaging?)

Thanks for the update

The draggable preview image is a great addition and so is the effect pane scrollbar and the new color selector.

Thanks!

no, i just fixed a minor bug that affect primitive edge color. that bug add dilute emboss even if the emboss parameter is zero.

BTW, I didn't realize the gamma issue with resampling. I will do some investigating.

what i describe is actually a work-around for the issue. the proper way to handle it would be to use 1/gamma for all input colors, work in linear space to preserve as many bits as possible, and then gamma-correct the final output image. when you spend some time with this stuff you quickly realize 8 bits isn't enough per component, not even close. 12 comes close, and 16 or 24 is more realistic. gamma-adjustment during a resample allows for very thin elements to be maintained. for example during a 1/4 scale, a single pixel wide white line would disappear, becoming only single dots of gray once in a while along the line. with the right gamma adjustment the line is maintained as a smooth dim gray line.

i can also recommend implementing dither into any gradient generators. you only need to add white noise at a level one bit less than the color data, so if you have color data in bits 8+, noise would be filled in bits 0 - 7. the result of that is all the color band edges get randomly shifted around by one level in the output making them look far smoother. it isn't even a requirement to use only one bit less, you could fill 0 - 6, or even only 0 - 5. that would make the smooth "dither edge" thinner between plateaus of flat color.

another kludge work-around for working in non-linear color space is during a gradient fill, the start/end values can be adjusted and the result can be adjusted back making the gradient flat rather than curved.

Thanks for the update.
The color selector windows has a bug though: it is not possible to enter values by numbers (the colour doesn't change after the input).
Also it would be nice if the windows would remember it's position (or always appear in the empty aerea below.)

* Color-window position saving
* Improved Color-window numeric value manupilation by keyboard
* BugFix: Sometimes crush in plugin 'SetLayout'

KnobMan 1.37 Release

http://www.g200kg.com/en/software/knobman.html

What's new in Ver.1.37
* Support APNG (Animated PNG) export
* BiDir (shuttling) animation support when exporting as a animation
* KeepDir option for rotation is added
* Save the window maxmized state
* BugFix: Cant undo primitive-color change

APNG is animated PNG file. downward compatible to normal PNG files.
FireFox / Opera will show animation. others will show still image.

This is a APNG sample. Also be used the 'KeepDir' option for numbers.

hi g200kg,
just wanted to say thank you for the update and good to see you continuing the development! i was a bit demanded the last year, so i was a bit quiet here, but i'll be back soon in a more regular fashion...

keep up!

It's kinda funny to read the first page of this and see people implying there's no need for another knob generation tool. What growth Knobman has seen since those early posts. Thanks g200kg!

see, that's what seperates the boys from the pr developers... continuum...
