I am trying to make passport photos for three different people.

And I think to finish up with an image suited for your typical print shop where they print on 4" x 6" paper and usually get about eight passport pics on the one card.

So I've been making the passport pics from different photos all supposedly crafted to be of the required size (48mm x 33mm in this case ) and I have finished up with the 'passport pics'  with these details according to GIMP:

1.   737 x 1072 pixels.   4" x 5.9"             180 x 180 ppi
2.  689 x 1003 pixels   3.82" x 5.57"        180 x 180 ppi
3.  630 x 918 pixels     3.5"  x 5.1"            180 x 180 ppi

So it hasn't worked out.  They're all different.

So am I using the wrong method?

Or can this all be fixed at this stage?

Right now I can't even cut and paste them successfully onto a new canvas of 4" x 6".   Can paste them on but they're too big and I can't move them around to tuck them into the corner.  Hence I never even get past the first one.

The method is to calculate the pixels per mm by measuring the head height in pixels right there in GIMP and dividing that number by the required head height in mm as specified.  (30mm)

I then know the pixel dimensions of the rectangle I need to cut out because I just multiply those pixels/mm by the height and width (48 x 33).

Sounds alright.   But it's not working too good.

Unless it can all be fixed now.

Or is there an entirely different way to go about it?

Hi everyone,

I'm new to this forum so apologies in advance.

I have no Library Folder in my Preferences (! trust me, I'm sure I've looked carefully) and I wish to import my Mac fonts from its Library folder.  How do I re-instsate the Gimp Folder.  I'm not a 'coder' or deeply software literate (but am a hands-on Mac user for countless years) so an idiots guide would be most appreciated.

Hello,

I'm trying to improve the following photo:


  IMG_1488 - v - L.xcf (Size: 938.31 KB / Downloads: 569)

My camera had too much haze on the lens that day, causing the image to not be as crisp as it could be. I've improved it somewhat by increasing the contrast and the saturation a bit, but it could still use some more improvement. Other than increasing the contrast and saturation, does anyone know how to make images more crisp?

I'm trying to make an acceptable passport photo.  There's 'edge shadow' - you know?  Subject too close to the  back wall when the photo was taken and one side has a little shadow outlining it.

How to remove that?

I notice that there are 2 new scaling algorithms. These are LoHalo and NoHalo. How exactly do these work? I've found nothing on the internet about them (for example academic papers on image scaling algorithms), so I assume that they are exclusive to the Gimp software, have been invented directly by Gimp's developers. So I'm hoping somebody on these forums can explain exactly what calculations it performs. For example, are they based on the Cubic algorithm? Or maybe based on a Sinc function? Or are they based on some kind of AI, that "sees" the image in the same way the human brain sees it, and so actually attempts to make a reasonable effort to scale the image based on what would look the most natural to the human brain?

Hello...

I need to draw some images for LCD screen used in embedded controller.
So I open gimp and set 128x64 pixels image and draw it.
The image on computer screen is perfect but when I upload to the embedded screen it's ugly as aspect ratio is wrong. So how to change aspect ratio for preview on computer to mimic that for embedded lcd? The LCD is 128 x 64 pixels but it's near square.
So I need to draw on 128x64 matrix but somehow squeze image from left and right on preview. Is that possible at all?

Thanks.

Hi everyone! I have a pretty big image (it's a logo) and its dimensions are 6900x2500. I am trying to shrink it down to a width of about 500 but it always comes out pixelated. Is there anyway to shrink this image without losing quality? Thank you very much!

Hello GIMP gurus,


Is there a way to turn an image into indexed color mode with a custom palette while specifying a number of colors as well?

I want to say turn a full RGB image into let's say 8 colors (indexed) but not generate optimum palette but 8 colors from my palette of colors.

Quote:Currently,
the Cross-stitch turns image into indexed colors (number of colors specified by user).
Then it replaces each indexed color by a closest match DMC thread color.
This process isn't the optimal, since turning to indexed colors already does some conversion and then matching DMC colors does some more conversion to it's 2 conversions which could take us further from original.

I was thinking of using the indexed colors where you specify a palette which I could make that already contain the DMC thread colors. So that it's one conversion so it's better. But now the problem is GIMP doesn't allow you to specify number of colors when you specify a custom pallete.

Any ideas on how I could do this? reducing number of colors while using a custom palette?

Hey everyone, this is my first post here and I'm hoping for some advice.. Months ago I downloaded a t-shirt mock up template to post online, I have tried many tutorials written and on Youtube over months to try and figure out how to actually get the t-shirt to show up, I just cannot figure it out. I'm running out of ideas how to figure this out anymore so thought I'd ask here.. Any ideas or a direction to point me in would be much appreciated.

I have attatched a screenshot
   

New one. Purpose: showing a stack of things. Gimp layers, but this script was written to help me make drawings for a presentation on Docker images and their union/overlay file systems.

Assume you have an image with several layers like this:
