  GIMP not using Windows Libraries
Posted by: ajax - 02-04-2018, 06:59 PM - Forum: Windows - Replies (2)

On my Windows 7 system, GIMP seems to assume that pictures are located in a folder named C:\user\name\Pictures no matter where they really are.  Windows, I believe starting with Vista, began using a concept called Libraries within which user data (i.e., documents, pictures, music, video, etc.) is stored.  While the default location is on the C: drive (i.e., system partition), the user can relocate them to another drive/partition.  This was also true of the "My Documents" folder on Windows systems prior to Vista.  In order to make my systems less fragile I've always located this user data (i.e., work product) on a different partition than the one containing the frail Windows system.

It would very desirable if GIMP could use/recognize these libraries rather than assume something that is not always correct.

  Default startup tool
Posted by: adiabat - 02-04-2018, 04:12 PM - Forum: Linux and other Unixen - Replies (2)

Gimp selects the Airbrush tool on startup. I'd much rather start with a non-destructive tool like Rectangle Select. Is there a way to do that?

  Introducing "inline code"
Posted by: Ofnuts - 02-04-2018, 12:31 PM - Forum: Gimp-Forum.net - Replies (5)

I have a thing for the "inline code" in markdown. So I have added it equivalen on gimp-forum.net. Text surrounded with backticks is:

  • shown in a fixed size font
  • included in a box, like this
Code:
like `this`

I find it nice to distinguish what should be entered/used: Open the file with File>Open as layers...

  Removing White Pixels from Grayscale
Posted by: pongiste - 02-03-2018, 07:19 PM - Forum: General questions - Replies (10)

I have used Gimp a bit in the past but have decided to adopt it as my main image editing software.

One of my most frequently performed tasks in Photoshop is removing the white background from pure black-and-white grayscales by dragging the gray channel onto the dotted circle option in the channel menu (sorry, away from my laptop at the moment so can't be more precise) which selects all the white pixels allowing me to delete the white pixels in one fell swoop.

Is there an equivalent workflow in Gimp? Thanks!

  Differences between software used to view digital images
Posted by: ajax - 02-03-2018, 06:09 PM - Forum: Other graphics software - Replies (3)

The post is not specifically about GIMP but rather about the general concept of rendering digital images for display on a computer monitor.  It is provoked by an observation triggered by Windows Photo Viewer (WPV) and pertains to the problem of obtaining a consistent result when viewing a digital image which I think is the main objective of GIMP.  In that, GIMP is producing something that needs to be useful with all manner of hardware and software.

In this case we're specifically talking about viewing a digital image on a computer display monitor but I would think the same problem exists with all manner of other devices used to display graphical images.  My recent interest in learning about digital image editing has lead me to learn that color management is a pretty complex subject and that differences exist between all of the devices involved in the process (i.e., work flow) of creating an image.  I also recognize that there is an inherent problem in trying to produce an image whose only purpose is to be viewed but that we don't have any control over what devices our audience might want to use when viewing that image.  However, it is really troubling when a fully developed image looks dramatically different when viewed on the same device using different software.

I offer as an example a photograph in the form of a jpg image developed by a camera.  Since I also realize that you will be viewing anything I can try and show you with equipment and software unknown to me, the only way I could think to accomplish my objective was to photograph my own monitor while displaying an image.  Keep in mind that image quality is irrelevant in this case the only thing I'm wanting to demonstrate is difference, which I'm thinking should be apparent no matter how you are viewing this image.

Here is a photograph of a photograph being display on my monitor with 2 different image viewers.  In that, the exact same file has been opened by each viewer.  The one on the left is the WPV that is part of Windows 7 and the one on the right is GIMP.  It looks to me like WPV is the outlier.  In that, whatever differences might exist between other viewers (i.e., other than these 2) are subtle enough that they are not so apparent, at least to me, from what GIMP shows.  However, I'm inclined to think that whatever explanation might exist for the difference demonstrated here could also apply to any software and that all such software may in fact be different in the same respect even if those differences are not sufficiently dramatic to be apparent to me or maybe even to you.  It would be much more comforting to learn that WPV is an anomaly and that by simply not using it this apparent problem is solved.

Can anyone explain what is happening here?

  Scaling layers and loosing resolution
Posted by: grit - 02-03-2018, 06:06 AM - Forum: Gimp 2.10 - Replies (3)

When I scale down and rotate layers in 2.9.8/9, resolution is decreased and layer is blurred.  I remember this wasn't like that before.
 
Is that a bug?

What can I do get GIMP to load faster? It loads very slowly, mostly with the finding fonts window.

  Crop Preset Problem
Posted by: abcjme - 02-02-2018, 03:57 PM - Forum: General questions - Replies (6)

I input specific size and position quantities for the crop tool, and I saved that preset. Well, the preset loads just fine, but when I go to crop, I have to press the preset 4 times for it to adjust properly! Ideally, I'd like to just have to press 1 button after I load the preset. Is there a way to get this to work more efficiently?

  Batch combine multiple images together
Posted by: josip - 02-02-2018, 02:20 PM - Forum: Extending the GIMP - Replies (5)

Greetings!

I am absolute new to GIMP (and any other than MS Paint...)
My problem is:
I have 6 pieces .bmp images of same size
Rotate them 180°
then combine them into a 3x2 format and save the result.
(or combine in reverse order, then rotate the result 180°)

It's not a big deal in paint, but I have a few thousands of those sixpacks, and I would like to automate the process.

I'm using Windows and quite familiar with windows batch, therefore when I heard that Gimp has powerful command line features I was happy.
But honestly, after half a day of searching forums and looking trough procedure browser, I did not get closer to the solution.
I dont even know where to start.
I can insert images to multiple layers, but cannot move them.
Is there a simple "move"-like command, or I have to write a complete plugin for this?

Please, if this is not some incredible hard task, help me with with a little starting kick.

[Hi! Sorry for bad english!]
(yes, I heard about ImageMagick, but I work on a company PC and can use only whitelisted softwares. While GIMP is accepted, IM isn't.)
