It's just a case study... let's call it Linear Motion Blur along a Path (with Perspective)
I saw this PS tuto > https://youtu.be/cL1BvOtd5zY?t=333 and told myself "let's do it with GIMP"

Below is what I came with at best I can think of (I did tried with partial selections and linear motion blur, but it's quite cumbersome, I'm searching something more straightforward like the paths),
If you want to try:

Smudge tool Brush: 2. Block 01 > @90 degrees > Dynamics > Track direction

Edit > Stroke path with the smudge tool
anyway it's all in the screenshot

   

But I am not truly satisfied for multiple reasons, as you can see on the "coupole/dome" the blur is fragmented and it's not a true linear motion blur, also the brush keep the same size which lead to some "blank" between paths that I need to fill with secondary paths (the shorter ones), overall it's not clean...
I think the best solution would be to do a "Linear Motion blur along the Path" where the size is increasing as it goes toward the end of a path, ( you might have better idea, if so please feel free )
In the end,  I would like to know if it's possible to do a linear motion blur along a path, in a way or in another way... if so how? any idea? or is it possible to have a Linear Motion blur between 2 Paths?

What do you think? Am I on the wrong path?  

What I mean is if you have an image which is too big or the wrong shape for printing on the paper you have in mind, say A4,  then is there an easy way to select and maybe enlarge or shrink selections of that image in order to make a satisfactory print out?

Like I have a long rectangular image. It is a photograph of what was a long rectangular piece of paper.

Now  I want to print it across a number of A4 sheets and I will stick them together.

If I could for instance  move a rectangle across the image that represents the size of an A4 sheet at that resolution and increase/shrink the size of that rectangle as I pleased - while at the same time as I enlarge and shrink the area within it always represents what will be printed on an A4  page - then I'd be helped enormously, I think. (and then press a button and have that area set aside as 'print selection 1 or something' or sent straight to the printer)

Is there such a feature somewhere or a method that achieves the same end?

I will attach the image.

Hi, I've got some bitmap images (hand drawn maps actually) which are simply all black details on a a solid white background.  I'd like to do some basic recolouring of these maps - making the rivers blue, footpaths red, and so on - which seems simple enough but I'm struggling to work out a way of doing this with gimp.  I want to have a fixed palette of half a dozen or so different colours that I can select one of, then be able to brush over part of my image so that anything which is black gets changed to the colour I've selected.  I'd need to have some control over the brush shape / size too.  It seems simple enough but I'm struggling to work out a way to do it.  Any suggestions would be much appreciated!

I would like to select left half of my image and mirror it onto the other one, that's all, how do I do that?

How do you use your graphics tablet ? I thought about using them for icons but it appears much tricky than I expected. I thought it would be like me drawing on paper. But it is far from it on Inkscape and GIMP. There is considerable vibration in what I draw. So it is not very clean for direct use. I am beginning to think that mouse is more useful unless I am going to trace over a photo.

How does a graphics tablet help you ? Is it mainly paining on GIMP and Krita ?

When I have an image cutout and set to a new layer, if I go back to that layer and say "alpha to selection", it does not show the outline around my cutout? It used to do this but lately it does not show me the outline. When trying to add a border or grow my selection, it won't show me how much it will grow by. I'm just left guessing. How can I get the outline to show up again? I am using Gimp 2.10.22 which is the most up to date for Mac.

I want to change my avatar in User CP, I upload one 100x100 png 20kb only and nope, no can do, even it says successful... avatar do not show up, tried with jpg, same problem...

I was so lucky to get this tablet (One by Wacom). I am very excited and I was able to use it nicely on Inkscape after choosing it through input devices. I first tried it on GIMP but whenever I use a paint brush and Stylus it shows an error window. All I need to do is select the paint brush and use Stylus to touch inside the canvas for this error to pop up


   

Is it possible to make temporary lines to serve as a border for filling, and then when we are finished with the filling, we delete these lines? Or what do you suggest? Because sometimes there are open areas on my image and I must complete and close the gaps by drawing with brush or pencil there but they stay.

Hi, is there any brush we can use to get a " shine " effect like this ?
