Question Align side by side horizontally - No gaps. - SOLVED
Posted by: Krikor - 09-03-2022, 03:45 AM - Forum: General questions - Replies (3)

Hello All,

I'm having the following difficulty:

I have several layers, they are all the same height but differ in width;
All are now aligned vertically;

I want to align them horizontally so that they are juxtaposed; as close together as possible without overlapping.

Ideally, the top layer should be on the left of all layers, followed by the layer below it on its right, and so on until the last layer is positioned at the other end of the horizontal (on the right).

With Inkscape there is the option:
"Move objects as little as possible so that their boundings boxes do not overlap."

I tried it with the Alignment Tool, but I never really understood this tool, and I didn't get that kind of alignment.

I thought the "Distribute targets evenly in the horizontal " option would do the job, but not even close.

How could I achieve this alignment optimally?

Thx!


Insisting I found a solution.

I had to sum the width of all the layers (I only used 6 layers in this experiment) and then increase the width of the canvas size to that value.
After that, "Distribute targets evenly in the horizontal" did the desired alignment.

But having to sum the width of a hundred layers is daunting.  Undecided


I was wrong, I noticed now that there was overlap between the layers after using the technique described above.  Blush


Solved!

The arrange-layers-0.2.py plugin does just what I need!

I know which is the widest layer among the approximately 100 layers.
I multiply the number of layers by that width and the result I use as the canvas width value.

So just apply the arrange-layers-0.2.py plugin and like magic everything lines up!!

Thx Ofnuts! (I'm pretty sure this is your plugin)

  Will background color print?
Posted by: hsmokey - 09-02-2022, 10:02 PM - Forum: General questions - Replies (2)

Hi there,
We have a piece of art we're trying to edit and then save and print- We would like it to be a certain size but, as is, there is a gap between the size of the artwork and the 'background'. We would like to change the background color to match the border of the artwork, however, are unsure if the background color will actually save and print since it's not the same layer (or maybe not a layer at all?). Does anyone know if the background color will in fact save as displayed and print that way? Please see attached image for reference-

Thanks!

  problem with resynthesizer
Posted by: ian32 - 09-02-2022, 04:34 PM - Forum: Extending the GIMP - Replies (2)

I recently downloaded resynthesizer for Gimp and I encountered a problem with the transition from the resynthesizer folder to the plug-ins folder. 
Every file goes into the plug-ins folder except for the resynthesizer.exe file, the system gives me this messagge: "you need to give administrator permissions to move to the folder" and if I click continue it says "authorization is required to perform the operation" try again or cancel.
When I try to open the file it gives me three errors that saying it can't find three "dll" files that I installed.



Can you please help me?
Thanks

  Colour->Compose Only 1 Layer(?)
Posted by: 4Rajas - 09-01-2022, 11:49 PM - Forum: General questions - Replies (3)

Hi all - hope someone can help!

After I import 3 monochrome .tif files as separate layers and go to the Colours->Components>Compose i only see the top layer to select for each channel not the other 2 layers. Tried opening as layers; openeing separately and copying as layers, etc but no luck. This process works on other laptop with GIMP. This is a fresh install of GIMP. Is there a setting I am missing or ...? thx

  Jpeg file loaded with script-fu not considered imported
Posted by: cyril42e - 09-01-2022, 04:25 PM - Forum: Scripting questions - Replies (6)

Hi,

When I open a JPEG file with Gimp 2.10, either from the menu File/Open or with the command line "gimp file.jpg", the image is considered imported (this is in accordance with the spec), and there an entry "Overwrite file.jpg" available in the Menu entry (with the hint "Export the image back to the imported file in the import format").

But when I load the same JPEG file with script-fu:

Code:
(define (myload file)
    (let*
        ((image (car (gimp-file-load RUN-INTERACTIVE file file))))
        (gimp-display-new image)
    )
)
Code:
gimp -b '(myload "file.jpg")'

then the image is not considered imported: the Overwrite menu item is not available, the image name when trying to close Gimp is "file.jpg-1" instead of "[file] (imported)-1", and when choosing to export the proposed file name is file.png by default (thus PNG file).

This is annoying because instead of being able to save the result in 2 actions (click overwrite menu item + click export button), I now need 5 actions (click export menu item, change the file name extension or select the existing file, click export button, click replace button, click export button). I can mention that my actual script is more complex, performing some preprocessing, before leaving the hand to the user to perform manual operations and save (and the time saved by the automatic preprocessing is somewhat reduced by the extra steps for saving...).

I didn't find a way in script-fu functions to explicitly import the file, and I feel that the current behavior is not consistent with the specification aforementioned, Is it expected and wanted ? Should a file loaded like this considered imported, or should there be a way to make it considered as imported with script-fu ? Or did I miss something ?

Thanks

  dpi does not change
Posted by: rjhanson - 09-01-2022, 02:24 PM - Forum: General questions - Replies (2)

Hello,
I use to be able to go to the "scale image" function and change the x/y resolution, lets say 72 to 300.  I hit scale now, it closes, I reopen and it says that the resolution  has changed, image size has not, which is a bad sign.

I Save the file to "webP" and reopen, only to find in the properties that the file is the same size and the resolution is still 72 dpi.

I would say this function is not working correctly anymore, but it was in the past.

Anyone see where I am messing up?

Thanks
Richard

  save color values from transparent pixels
Posted by: zeuspaul - 08-31-2022, 05:03 PM - Forum: General questions - Replies (9)

When exporting to png there is an option to save color values from transparent pixels.  It is not the default.  I am still a newbie with transparent pixels.

I am tracing objects with the intent of later adding them to another image.  First I trace with free select and then I copy and paste the object to a transparent layer.  Then I export to a png and I get the option to save color values from transparent pixels.  I don't know whether or not to select this option.

When I zoom in on the pasted object on the transparent layer I see along the edge of the tracing what appears to be partially transparent pixels.  If I opt to save color values from transparent pixels will the object blend better when I add the png file to another image?

  How to get rid of the white line in the middle
Posted by: snowmansion - 08-31-2022, 10:56 AM - Forum: General questions - Replies (4)

Dear all,

I've been searching this forum for a way to get rid of the white line in the middle of the attached photo which is the result of stitching 2 scans together.
As I'm not entirely sure of the right terminology (I've used e.g. removal of crack/border/line) I wasn't able to figure it out yet. That's why I posted it in the general section.

Is there an option in GIMP that allows you to remove or enhance it in such a a way that it isn't visible anymore? 

Thank you in advance.

Sander
