An animated GIF may be the easiest way to show this:

Probably best if the actual "add node" action is restricted to mouse clicks, only?

Hi reexre. Sorry if this is a bad place to write you about a small PhotoModularFX suggestion. I thought GitHub might be better than email, but if I'm wrong, I won't do this again!

I downloaded the latest PhotoModularFX today to check out all the neat features you've added, and I found that the PhotoModularFX taskbar icon is all black. When extracting it to the desktop (or looking at its icon in the taskbar), if the user has a dark or black wallpaper like I do, it looks like PhotoModularFX has no icon. It might be worthwhile to add a bright outline (or glow, maybe) to help the icon stand out against dark backgrounds, since dark Windows 10 themes are more common these days.

Another idea for the taskbar icon could be to reflect the currently loaded image, if any. (GIMP is a good example of this.)

Just an idea. Thanks for the great program.

Would it be possible for PMFX to support alpha channels in 32-bit images?

Many modern images are 32-bit, and being able to manipulate the alpha channel alongside RGB would be helpful.

If this is too cumbersome, even the ability to pass an initial alpha channel, unchanged, from starting state to final state (and having it saved properly to e.g. PNG format) would be very helpful, instead of losing the alpha channel completely, as the current version does.

Alternatively, if you don't want to support alpha channels, maybe there could be an option upon importing a 32-bit image to composite it against a white background. (Or perhaps any color of the user's choosing?) At present, 32-bpp images are always composited against black which is not always desirable.

I notice that PMFX's current Gaussian Blur filter slows down significantly as radius increases. Since (I think?) PhotoModularFX works on floating-point data, it is a good candidate for an IIR implementation of Gaussian Blur, similar to what GIMP uses.

A nice BSD-licensed reference implementation is available here:

The original 1994 paper that inspired the approach is available here (free download):

https://www.researchgate.net/publication/236268568_Signal_and_Image_Restoration_Using_Shock_Filters_and_Anisotropic_Diffusion

On a 10-megapixel image (3872x2592), PMFX takes about 135 seconds to process a 3-channel gaussian blur. In PhotoDemon, IIR code very similar to the above project does the same thing in about 6 seconds, and that's including the overhead of moving all data from 8-bit integer RGB to 32-bit floating-point RGB and back again, plus processing a fourth channel (alpha )- so PMFX could be even faster, I think.

Hi @miorsoft!

It would be convenient to have a built-in way to copy the current output to the clipboard. Maybe a small button on the top-right panel?

Thanks for considering!

I'm not sure what the name is for this widget (Apple calls it a "picker"):

...but it would be very helpful to add mousewheel support, so you can quickly scroll through available options without clicking. This is how closed dropdown boxes work on Windows 10 (you can mousewheel scroll the box without clicking it) and it makes exploring options much faster.

Thanks!
