Re: [Gimp-user] Resizing

2021-02-03 Thread Jay Smith
In addition to ImageMagick which can do all sorts of great stuff, to do 
this kind of thing we had to resort to writing a Perl program.


Our inputs are TIFFs and our outputs are JPEGs in four different pixel 
size-ranges.  The output pixel size for some is fixed (i.e. for 
thumbnails) and for others is variable, but within a range, depending 
upon the input size.


On one hand it is "simple" when you describe it in words, along with a 
little hand-waving.  However, trying to do it programatically is a bit 
messy.


Perl does have image handling modules that help a lot.  (Disclaimer, I 
did not personally do any of the real work; I just did the talking and 
hand-waving.)


We have a library of many tens of thousands of source images as TIFFs. 
We keep them as TIFFs for ultra-long-term purposes, also for 
print-on-paper use, and don't want any compression, etc., etc.  New 
source images are dropped into the library at will.  A command is run 
several times per week, or as needed, which compares all the sources to 
all the targets and makes/remakes any new targets where targets do not 
yet exist or any source's timestamp is newer than the target.


It can be done.

Big operations take time. Go and make a coffee. I have 32 GB of RAM and a 200 GB
tile cache in SSD. Sometimes the operation takes 5-10 minutes, which is hardly
anything. It might take 2 hours to save as well, but I can do something else
during that time.

Notice the memory usage in the title bar and/or status bar. When GIMP
is using all of your memory, everything will be very very slow.

(1) Make sure the "tile cache size" is set to at least half of your
physical RAM in Edit->Preferences. You may need to experiment as you
didn't mention operating system or how much memry you have or whether
32 or 64 bit.

(2) there were some speedups - get 2.10.14, not 10.4, and see if that
helps?

i routinely work with large images but not with 35 layers. Sometimes
40,000 pixels on a side.

For an 8-bit precisoin RGB image like JPEG, each pixel uses 3 bytes of
memory. So the image will be three times bigger than we might expect.

So, divige 1.5 megapixels by 3 and aim for that number.

1.5 megabyets is 1024 * 1024 * 1.5 is 1572864, but we have to divide
that by three, which gives us 524288 pixels.

So it's the same except with a new number:

To get the image size in the title bar (it's already in the status bar)
go to Edit->Preferences; under Image Windows near the bottom is Title &
Status. In there at the end of the Image Title Format, add a space and
then (%m) to get the memory size.

I also find it useful to put %EE at the start (with a space after it),
which gives an E if the image has been exported since it was last
changed.

This is a slightly mathsy reply but i hope the short answer isn't too
intimidating :)

Is it megapixels or megabytes?

If megapixels, that's 1.5 * 1048576 pixels = 1572864 pixels.

Short answer


Open up scale image and note the current width and height of the image
in pixels (set the units to px in the dropdown to the side of Height if
yo uneed to) and then...

1. divide 1572864 by the current image width in pixels.
2. multiply that number by the image *height* in pixels
3. take the square root of that result
4. put that number into the Height field in Scale Image
5. the Width field should update auomatically

Handy Hint: the result of scaling down an image looks bst if it's a
factor of two, so swich units to % and ee. If it's nearly a factor of
two, 51.2%, you'll get a better image by scaling down to 50% and then
if needs be adding a solid border to make up the size.

You may need to sharpen the image after scaling; use LoHalo or NoHalo
as "interpolation" in the Scale Image dialog to see if they give a good
result.

Handy Hint Two: scaling up to make an image larger is asking GIMP to
invent data. It doesn't do a good job at being creative. You can use
the resynthesize plugin to try and do a better job, maybe.

If you needs megabytes, it depends on the bits per pixel, but if 8, the
calculation is similar but for an RGB JPEG image (no transparency) it's
that same number 1572864 divided by three (for red, blue and green
values for each pixel). That's 524288, so use 524288 in the formula to
get megaytes instead of megapixels. I think.

Long answer:


If your current image is w wide and h high, then it is
(w * h / 1048576) megapixels currently.

You need to end up with w * h = 1048576 * 1.5
that is, neww * newh = 1572864

But we want to keep the aspect ratio of the picture when we scale or it
will distort. So, we need that
neww/newh = w/h.

 Armed with this, we can write, by multiplying both sides by neww,
neww = w * newh/h
and, from before,
neww = 1572864 / newh
So,
w * newh/h = 1572864 / newh
multiplying by newh * h and dividing by w we get,
newh * hewh = 1572864 * h / w
So, newh = sqrt(1572864 * h / w)


So, in scale image, in the Height field, use a calculator, substitute
in the current w and h values, do the calculation and take its square
root.

Megapixels are a product of (roughly) width times height of an image in
pixels, and as such not really properly specified - there are many ways
to multiply two of these values and arrive at 1.5 megapixels.

Going by the following chart (and assuming 1.4 MP or 1.6 MP are close
enough, and fairly common display size - or at least height -
standards), I'd go with an image of either 1440x960 pixels or 1536x1024
pixels.

https://en.wikipedia.org/wiki/File:Sensoraufl%C3%B6sungen.svg

I'd opt for the former at 1.4 MP, though.

With such a large percentage reduction you are always going to lose a lot of
detail. There is absolutely no way around this. You just can't represent the
same amount of information in such a small number of pixels.

Since 398 isn't an exact multiple of 28, it may help to crop it first
to 392 pixels by 392. Then scale down to 1/7th the size (56 x 56) and
use curves to make sure you still have contrast, then scale down 2x to

Make sure the image is in 16bpp or 32bpp precision (assuming Gimp 2.10)
and RGB, not indexed.

Without seeing the original image it's hard to give better advice. The
images on the front of fromoldbooks.org are mostly scaled down with
Gimp in lohalo mode, often to between 1% and 3% of the original height,
but at 200x300 pixels i have a chance of sme detail.

Are you talking pixels as the unit, ie, 398x398 pixels and trying to reduce 
that to 28x28 pixels.

If so, I think you are going to be out of luck as the reduction is too great.

Using reductio ad absurdum, what would you expect if you tried to reduce the 
image to 1x1 pixel?

You cannot expect to have anything like the same information (image likeness) 
when reduced to such a small amount, approx .6% of the original).

[Gimp-user] Resizing default screen shot size

2017-09-15 Thread mjolnir
I recently installed GIMP 2.8.22 on my laptop, and find that when I 
create a new image from a screenshot, the resulting image is 1857 x 1094 
pixels, instead of the selected scren size of 1920 x 1080 pixels. Is the 
screenshot size configurable in the GIMP someplace?

Probably using the wrong tool or do not understand how the tool works or
expecting click-n-wish to work

Without greater details of the image you are using, all a bit of a guess but
this is a demo of

1. Image menu -> Fit Canvas To Layers

2. Image menu -> Resize Canvas

Either probably do the job, only 1 minute 30 seconds so no great epic.

How _exactly_ did you try to resize the canvas? What menu item did you
choose to do this?

What I would do, after cropping the image to 2 inches square, is to 
select "Canvas size" in the Image menu. In the dialog menu, in the 
"Canvas Size" item, I would  change the unit from "px" (pixel) to "in" 
(inches), and set the height and width to the desired values. Below 
that, in the "offset" section, I would click the "center" button at the 
far right of the dialog box. The file is now ready to export to any 
supported file format you desire.


Having written that, it's not clear exactly what types of images you are 
using, and whether or not scaling is the best tool to use, but if you 
don't want to change the proportions of the elements in the image, you 
may want to "resize" rather than "scale" your source file.

Re: [Gimp-user] Resizing

2016-11-28 Thread Rick Strong

Cropping and Resizing are two different actions.

To CROP means to cut away stuff so that you are left with only—in your 
case—a 2 inch square image.


To RESIZE means you have reduced an image in size, not cut anything away. If 
your original image was not EXACTLY square you can never end up with a 
perfectly square smaller image. This is because RESIZING makes things 
smaller, or bigger, by keeping the proportions or aspect ratio of the image 
the same as the original.


The tool you want is the CROP tool. TOOLS > TRANSFORM TOOLS > CROP.
- Check FIXED > Aspect Ratio.
- SIZE > Inches (In)
- 2.0 ,  2.0
- Make the cropping square bigger or smaller to fit by moving the corner 
boxes.

- Press Enter.
- Save it as a GIMP .XCF, then  EXPORT AS whatever you want: JPEG, PNG, 
whatever your lab wants

- Put your cropped image into 4 x 6 document that will go to the photo lab.

Smile at the good job you have done! {8>)

Cheers,
Rick S.

Re: [Gimp-user] Resizing

2016-11-28 Thread Partha Bagchi
Make sure that your original image is square (2x2) prior to resizing.
Otherwise your aspect ratio will be wrong and the image will be distorted.
Then use scale image and then copy the image. Open a new 4x6 document and
paste into it. Finally export the image as jpeg.

Can you describe step-by-step how you do dit? You must be missing something?


Also, what is the size of the final image (in pixels), and what to you

You are probably resizing the image and not the layer.

Try this:

1. Make the left eye layer the active layer.
2. Use the rectangle select tool to make a selection around the eye 
   and quite a bit more, but smaller than the whole image.
3. Layer / Crop to selection
4. Clear the selection (Select / None)
5. To make the layer larger:
  Layer / Scale Layer

[Gimp-user] Resizing an imaged - revisted

2014-11-20 Thread HarryA
Hello all,

I have photo of my wife which is an up close shot of the face.
Because she is near sighted the view of eyes through the tri-focual  lens are
made so small such that the side of the head shows through the lens.

I have removed the eyes to  separate layers (left and right eye layers)  when
the three layers are made visible it looks like the original image.

But no matter how I try I can not resize an eye image without the other layers 
getting resized also.  I can not un-anchor nor dissociate  the eye layer from
the face?

The layers are not anchored together in the layers dialog. 

How does one do that?

thanks in advance,
HarryA

The distortion is only if you do not keep the aspect ratio locked. If 
you keep the dimensions locked to maintain the aspect ratio, there 
should be no distortion.
