I am having difficulty with gimp (version 2.8.10).

To what does the layers dialogue refer?

Regarding Channels dialogue, how do I use the Red, Green, and Blue channels?

What is the function of the eye?

I am having difficulty with transparency. After adding alpha, how do I select the colour in the image to achieve transparency?

Why is it called alpha?

Thank you

Hi All,


I have been watching the you tube on how to do cutout. I followed all the steps, however when I Invert the picture and hit the delete either the car I traced disappears, or the background goes all white?  I cannot get the checkered background?  I am enclosing the original picture and the one I cutout but cannot get checkered backgound.  If anyone could look at this and let me know what it is I am not getting?  I really am trying to learn so I would appreciate if you coulf tell what steps I must take to fix this.

Again, Thank all of you for your support and guidance.

I would like to make a gimp project collaboratively with a friend, but I haven't found any methods that are possible.

By collaborate I mean if there were two computers connected via ethernet cable and they both had gimp. Would it then be possible to have them work on the same image so that one could see what the other had just done and vise versa.

My first idea was to make both computers use the same image simultaneously, but that didn't work because gimp seems to load the image in memory. So the next thought was to share the swap/memory/temp between the two computers, but i'm not sure how to even do that. (by swap I mean the gimpswap file or any other tile caching.) I tested one idea by opening the same image in two gimp windows but they just edited them separably.

I seem to remember a version of gimp would always use another file with the same name but with a ~ at the end in the same folder as the one being edited to save temp data of some sort. I am now wondering if you could use that simultaneously?

I have looked at compiling my own version of gimp, but probably wouldn't know where to start. Possibly making a plugin might help, but again don't know what to look for as a reference.

Thanks in advance to anyone who can help me.

Ive outlined a face and am now trying to fill it in. The bucket tool just fill sin the whole screen or fill it in and leaves the face outline...how do i just fill in the designated areas. Every tutorial i follow seems to work for them but not me...im so annoyed please help my non knowing self!!!

Hello all,

   I am new to the forum.
I did a couple searches, been over Google a bit but ....

   If I can explain this: ( I am sure I might not use the "proper" term somewhere, please excuse me )

    I have a png image with a transparent background.
    If I re-size the canvas, the only method I know to make the new image include the
expanded canvas is to Image -> Flatten Image.
   This removes the transparent background and replaces it with the present background color from the tool bar.
   The same type of thing happens to me with text. In order to have the text as part of the image,
I have to go to Image -> Flatten Image. Once again it removes the current transparent background
and replaces with the present background color from the tool bar.

    My question(s) is/are then:

    Is there a way to make the image not loose the transparent background, ie
use something other than Flatten Image
    or
    Is there a way to set the background selected color on the tool bar to transparent?

Thanks so much for your time,

kumado

I am looking at getting a new computer. Have seen a Lenovo 'all in one' computer that I like.
Lenovo IdeaCentre 300 23.8" AMD A6 1TB 8GB All-in-One


Not heard of Lenovo before.  I will be doing graphics work. (Photo restoration, Fractals etc on it). I don't play games alot. Would this be sufficient and has anybody heard of this brand before and how it  works?

At the moment I am using a Toshiba Laptop but gimp wont complete a lot of stuff because it says I don't have the memory, I cant do full resolution fractals plus my fan has stopped working. I can probably still use it for smaller things after I get that fixed but want another bigger one for other stuff

Fairly new to the workings of GIMP. I'm using 2.8 with Paint Studio 2.0 addon and a bog-standard mouse.

I'd like to ask if there are any setting combinations (brush types, dynamics and paintbrush modes) that will create the brush stroke and paint effect of, for instance, oils.

What I'm looking for is a stroke which will take the colour from the brush as I paint, leaving a kind of smear or scraped effect at the end of the stroke.

I know this is possible when using a mouse, as a couple of the online paint programs I've used feature just such an effect.

To be honest I'm not altogether sure how the various Dynamics work, because it doesn't seem to matter which I pick, all the strokes come out as simple, digital block strokes with no variation or texture.

Any help on getting different paint stroke effects will be very much appreciated.

I did this one a while back, I think it was from 7 different image of a lotus flower.
