I'm asking, because you seems so happy with it, like you don't want to change and it looks like a SEO spam...

Yes GIMP can do it like any similar software, those are the very basic functions that any online/offline image processor do.

On a side note: If the website you are enjoying so much speaking about is "free" (for the moment), the software to download from this website is NOT.

gimp vs imag-r:

• imag-r: $199,00 (very limited function & over priced)

In the end if I'm obliged to buy a software for that purpose, I would buy Affinity Photo/Designer ($49 life time license) rather than imag-r""

no i am not promoting the imag-r site??? why do you assume this? I am askign how to do the SAME in GIMP so i can get AWAY from imag-r
are you trying to promote others away from gimp? do you not like Gimp? do you want gimp to be discontinued? I say this because you are wanting me to use imag-r so bad.. Oh, and yes, imag-r is free, i have been using it for a few months now for my laser engraver, but trying to get away from it, but it feels like you want me to continue to use imag-r?

since you missed my original question, here it is again, copied from my OP: does gimp2.10 have a simular feature so i can process my images in gimp for laser engraving?
thanks

Again Sorry, and Welcome

Not sure about laser engraving, but for the image processing in GIMP, yes it's quite easy
If I understood, you do need a black and white picture?
GIMP can automatically put your picture in grayscale (you can chose this in the preferences), crop/resize and DPI it's all easy access and DPI can be set to your preferred value as default

adjust brightness, contrast, sharpen, etc manually, or hit the auto button.
All those tools are in "Colors" and in "Filters" also GIMP has even multi "AUto" button

Skimming through what must be an over long tedious video, I got these examples: https://imgur.com/XW95pDa.jpg Gimp can certainly do that. As well as changing the mode to greyscale, desaturating a colour image gives some variation. The program options seem to be limited to scaling, contrast and brightness, sharpen, some effects, which I did not see, inverting the image.  In Gimp something like this: https://i.imgur.com/gTHg0cs.jpg There are third-party plugins that might be useful for extra effects.

Image format: bmp / png / jpg - no problem for Gimp exporting those. SVG will be a problem. Gimp is a raster editor, for svg  Inkscape is the application to use.

No, Colors > Auto > White balance... will do it (on B&W as well)

i eventually want to learn how to do it manually,
If you are selling you laser thing,
Yes! indeed IMHO you will need to learn to do it manually for example if a customer want to engrave something which appear in the colored photo, but disappear with all the "Auto" function in B&W, you will need to know how to make it appears when it becomes B&W.
I would recommend you to learn the "Levels" first (it's a simplest version of the Curves), the "Auto input levels" in that tools is exactly the same as the "Auto > White Balance..." I spoke above
2 quick links I found for a good start to learn "Levels":
https://patdavid.net/2011/07/getting-around-in-gimp-adjusting-levels/
https://www.youtube.com/watch?v=U6kFhN4T8uc

but its hard for my eyes to see the difference with greyscale so i cant always produce the best images for laser engraving.
You are no obliged to start with a B&W, personally I would do Levels in Colors then use the mono mixer (Colors > Desaturate > Mono Mixer...) or use any desaturate method that give a quick result I'd like AFTER adjusting the color,
Why? because your conversion in black and white will always depend about colors and darkness/lightness of these colors.
I love this tool -> Colors > Desaturate > Mono Mixer
https://www.youtube.com/watch?v=_SdjdPGb4B0
But it's me only, if you don't like it, in the Colors > Desaturate menu you have other tools to chose from

Also when you have finished to adjust your B&W picture, you might want to take a look at this tool > Menu Colors > Threshold... If laser engraving is just made of black and white spots (no gray gradients), you might love this tool. But I do not have any idea what type of B&W you need to do laser engraving

(07-24-2021, 07:59 AM)PixLab Wrote: Ill have to see if there is a way to do split view with B&W photos so i can see the greyscale image and color image next to each other whilst i adjust levels or curves?

All the tools we've mentioned have a preview and split-view options.
The preview and splitview are always at the same place -> at the bottom of the tool dialog
And... Yes you can move the line which split the view
