  Command/API to move to particular coordinate?
Posted by: Ken Shirriff - 05-06-2022, 04:57 PM - Forum: General questions - Replies (4)

Is there a command / plugin / API that will center the window on a particular coordinate? E.g. I enter 2000, 3000 and it moves the window to that coordinate.

My use case is that I have a 10000x10000 image and a list of coordinates where I need to fix things. Currently I scroll, then stop to read the cursor position in the lower left, scroll some more, and repeat until I find the desired location, which is tedious. I'd like to be able to jump directly to a position.I looked through script fu but couldn't figure out if there is a  better way.

Thanks!

Question Script-Fu: gimp-image-get-filename does not return string?
Posted by: bliss - 05-06-2022, 03:26 PM - Forum: Scripting questions - Replies (1)

I'm probably doing something stupid?
(Scheme and Script-Fu first timer)

Does

Code:
(gimp-image-get-filename 1)
not return a string?
Script-Fu Procedure Browser says so at least.


Code:
> (string-length (gimp-image-get-filename 1))
Error: string-length: argument 1 must be: string

Thank you for your time and effort kind stranger!

I had to do:

Code:
(string-length (car(gimp-image-get-filename 1)))

Where the (car x) is the important part.

Seems to be a Lisp thing where everything returns a  pair or a list and car selects the first element of a pair/list.

  How to resize a selected object to a hd
Posted by: eedwards68@ymail.com - 05-06-2022, 12:37 PM - Forum: General questions - Replies (2)

I play this space game where you can create your own races but the final size of the species pics have to be 1920x1080. I find some cool pics of alien races but they may be of different file size and want to move of copy them to a blank pic that is 1920x1080.  Not sure on how to do that. 

I have a cool pic that is 739x1080 but I want to move the specific creature into a pic sized 1920x1080....  I have transparency, and alpha channels created.  Am new to this and would really like some help. Thank you in advance.


With the attached file I want to take that alien pic and move it to a sized 1920x1080 without distorting the pic of the alien....

  Multiplying images
Posted by: GloriaGlitter - 05-06-2022, 06:19 AM - Forum: General questions - Replies (6)

Hi there - I'm a novice user of Gimp so apologies in advance if this is a really simple question.

I have an AO image size of 1024 x 1024.

The image layer that I want to add is only 512 x 512.

I do not want to resize this to 1024 x 1024 as the pattern will be too large.

So what I would like to do is to take the 512 image and make 3 copies and make a 2x2 matrix so that my image is now 1024 x 1024.

I have been doing this in Paint but it is very much hit and miss to get the images to align properly.

Is there a way I can do this in Gimp?

Thanks

  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
