  Does posterize black and white use same value ranges each time?
Posted by: topher - 05-05-2022, 06:00 AM - Forum: General questions - Replies (3)

Hi,

I am trying to print the equivalent of a value swatch for graphite and charcoal drawings that I do and I am still fairly new to Gimp.

Ultimately when I posterize a black and white image with say 7 levels I am trying to get a print out of the 7 grey values used in the posterized image so I can match to graphite and charcoal values of my pencils and tools.

My question(s) around this:
- apart from indexing the image, creating a colour palette and then using gradients to print the colour palette, is there an easier way to be able to print out the grey values used?
- if I have multiple black and white images all using 7 layers when I posterize the image, will all images automatically have the same 7 values or will they be different slightly for each image?

Really appreciate any help on this.

Cheers,
Topher

  How can I host a Google classroom meeting with a different account?
Posted by: Chemist116 - 05-04-2022, 05:17 PM - Forum: Watercooler - Replies (1)

I've just installed the classroom app for my android device from the google play store. However I need to use a different account for classroom. When I run the app for the first time there is an Access window which tells me that I can log in by creating a new account. When I push that option the next screen allows me to enter my new email and password. But after doing this there is a warning message which tells me that my profile will be deleted why is this happening? Can someone explain this to me? Does this means that my already in use account in other google apps like youtube, gmail, samsung email, will be deleted or affected by this decision? Please I need someone to explain me this.

Assuming that after accepting delete and then I get to my classroom classes board. I click on the one which I am doing to administer. But I cannot find the Google meet icon where is it? How can I host a google meet from my class?. Please use a screenshot for helping me in this step.

Please note that by this time I already have created the invitation link that students will see.

Is it necessary to have Google meet set up previously? I mean for to use Classroom?. How do I set up Google meet?. Assuming that I already entered my google account, how do I enter or add a new account and switch to that new account in Google meet?. Can someone explain this to me please?. I ask this because, Is it required that google meet account matches the account to be used in classroom?.

I appreciate somebody could explain these questions to me.

  doing an aura
Posted by: aka - 05-02-2022, 10:20 AM - Forum: General questions - Replies (1)

Hi,

I am looking for a mean to transform one of the two first images to the last one.

Please note that :

- The two first images are the same, except the edge of the second (out of focus).
- The choice for the color of the aura, on the third image, is the opposite of the basis color of the image :

Blue <-> Orange
Yellow <-> Purple
Red <-> Green

But this is not mandatory.

Thanks  Smile

  Adjustment Layers
Posted by: Ritergeek - 05-01-2022, 07:58 PM - Forum: General questions - Replies (1)

I'm going through old emails and I found one from 2008 where I mentioned that "GIMP has promised that adjustment layers will be added quite soon. Fingers crossed." That was 14 years ago and we still do not have this feature. Is it still in the works? Should I continue to hope?

  RGB Levels - Adjustments Visibility
Posted by: Seasider4747 - 05-01-2022, 04:21 PM - Forum: General questions - Replies (2)

In Photoshop under Windows, one can see in the RGB Levels panel the effect on each colour of adjusting the black and white sliders by holding down the Alt key while moving a slider. See attachment. Is there any way of getting the same view in GIMP 2.10? Thanks in advance for any solution.

  Edit gif
Posted by: Luciole - 05-01-2022, 10:25 AM - Forum: General questions - Replies (10)

Hello !

First of all, sorry for my bad english, I'm not a native speaker.

I'm trying to edit each layer of my gif, found on internet (erase a part of the gif with an eraser) but I don't want to do the same thing for each layer, there are a lot and it's not very precise (and it doesn't work, anyway).

Can you help me ?

Thanks !

  Help with scaling a layer - image vanishes
Posted by: GloriaGlitter - 05-01-2022, 07:03 AM - Forum: General questions - Replies (3)

Hello there - I am a novice user of Gimp and I'm having a problem that a friend of mine doesn't and we wonder if it is a Windows 11 issue.  What I am doing is the following:

First I open an image that is size 1024 x 1024.
Then I open as a layer another image but this much larger at 3054 x 3054
It seems I can only see a 1024 x 1024 section of this larger image
I then use the scale tool and replace the width 3054 with 1024
As soon as I click into the height box, this 2nd image vanishes just showing the first image
I hit the 'scale' button anyway
I suspect my 2nd image rescaled has moved to outside of the visible area - on one occasion I was able to bring this rescaled image back by using move tool and keeping finger on right cursor key and slowly this image slid back into view but it doesnt do this each time.
Am I doing something wrong or is this a Windows 11 quirk since my friend on Windows 10 doesn't get this result - on her computer the rescaling acts as one would expect.
Grateful for any advice
