  Size problem in saved tif image
Posted by: MarcoCarta - 06-11-2024, 07:49 PM - Forum: General questions - Replies (5)

Hi all,
I face a problem in saving a tif image.
What I'm doing :
I'm editing a 3600x3600 16bits integer grayscale geotiff with 1 layer.
When I save it and reopen it with the Gimp 2.10, the image is 3602X3600 px and the layer have a 2px left offset.
Despite of numerous attempts to correct size and layer position, when I save it the same thing append.
Am I missing something obvious here ?
thanks for reading

  an example of image manipulation
Posted by: MJ Barmish - 06-11-2024, 12:05 PM - Forum: Gallery - No Replies

Hello, everybody
for those who are interested, here is an example of processing a photo to create the image of my site "Remains of a mausoleum" in five steps (because the number of attachments allowed in a thread).

First step : the initial, quite banal photo (I don't know why it can't be attached jpg 400px X 247px 103Ko ; when I try everything crashes ! ?)

Second step : first treatment in Canon DPP4 ; I applied my "gilging" tonal composition and straightened the perspective and cropped. You will see that we still have a photo

Third step : first processing in Gimp ; I apply the "despeckled" filter in recursive ; an interesting shape is outlined. It now remains to strengthen and clarify it    

Fourth step : second processing in Gimp ; I apply the "neon" filter in saturationTSV. At this moment the image is formed, but very "dirty" ; so all that remains is to clean it and improve colors (saturation, contrast...)

Then, the cleaned and finalized image (that of the site in the section History and Journey)

  Balancing colors across images
Posted by: jame0123 - 06-10-2024, 07:22 PM - Forum: General questions - Replies (2)

Hi there everyone, 

I've got three "blue pencil sketch" images which I've attached. 

I'd like to be able to adjust the blues in all of them to be as close to the same tone as possible. You'll see that I've got an example of a lighter blue, a darker blue, and one that's in between. Ideally I'd like to get all the images to be the same white as well. 

The kicker is that I've got 100 images similar to these I need to do this with, so I need a replicable process for getting all of these to the same-ish blue. 

I had thought perhaps I could do this by creating a color curve preset, but the issue is that the curve needs to be different for every image to get to the final destination. 

What's the right way to do this given that I've got 100 images? I'll compromise a bit on quality for speed purposes here.

  Any way to export a lot of pictures from *.jpg to *.dds
Posted by: misha.physics - 06-10-2024, 03:14 PM - Forum: General questions - Replies (9)

Hi. I'm trying to do something that seems pretty simple, but I'm not sure if it's possible to do in GIMP at all, but I really hope so.

I have an image "file.jpg". I open it with GIMP, then I go to "File", then "Export As...", I choose "DDS image" (there're two ones, I select the first one, I don't know if/how they differ from each other). Then I use the settiongs (I choose the compression - BC1/DXT1, other options are default):
[Image: YVoUTMfS]
(Sorry, my picture isn't vissible. It's on https://imgbox.com/YVoUTMfS)
After exporting I get "file.dds" picture.

So, I have a directory which contains several subdirectories each of which contains several *.jpg pictures similar to "file.jpg" (all picture are 512x512, but I think it doesn't matter). All what I need is to export all these *.jpg images to *.dds format ang get the results the same as if they were received if I exported them manually one by one as I've written above. The all exported *.dds file should have names the same as its input *.jpg files. Also, it would be nice to delete all input *.jpg files after conversion.

 I've seen some scripts for GIMP, but they look pretty difficult for me, I've never used GIMP before. Maybe there's a simple way to do it in Windows command-line CMD. (Also, I could make such conversion on Linux if it will be easier, than on Windows, although my laptop with Linux isn't so powerful). Also, I've installed BIMP and tried the "Batch Image Manipulation Plugin", but I havent found the *.dds format for exporting...

Hi, all,
I tried to post a new thread, but I can't attach any more images. For what ? Should I delete images that have already been published Rolleyes ?

  Where are preferences being stored?
Posted by: ajax - 06-09-2024, 04:12 PM - Forum: Windows - Replies (3)

This question pertains to Windows installations in general.  I'm having a problem when running different versions of GIMP on the same Windows computer.  It appears to me that the same Preferences are being used no matter what version of GIMP I might choose to run.  This is causing a problem when I might want to have different preferences apply to different versions of GIMP.  For example, when using plugins it is desired to associate the plugin version being used with the version of GIMP being used but that does NOT seem to happen.

On Windows one might expect that storing Preferences in the registry rather GIMP specific files would have this affect.  However, I haven't been able to find anything in the registry that looks like GIMP preferences.  Same applies to standard file locations such as those located within the AppData folder.
