Re: [Gimp-user] Resizing
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.

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.

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.

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. -- Liam Quin - web slave for https://www.fromoldbooks.org/ with fabulous vintage art and fascinating texts to read.

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. -- Regards, Michael GPG: 96A8 B38A 728A 577D 724D 60E5 F855 53EC B36D 4CDD ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

Re: [Gimp-user] resizing image creates blurry image
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).

Arghhh I have made a change in an image rotating part of it so that it now extends above the edge of the canvas. Resizing the canvas to layers does nothing. I had similar problems extending the canvas when I added an image from another file but nothing worked to fix that problem either. It was all so easy in photoshop- why is this so difficult -- View this message in context: http://gimp.1065349.n5.nabble.com/resizing-canvas-question-tp50350.html Sent from the Users mailing list archive at Nabble.com. ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list

What I previously did in photoshop was to crop it to 2x2 inches, save it, then place it into a 4 x 6 new document, then save it as a jpeg. 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. ns ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
Re: [Gimp-user] Resizing
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.

Re: [Gimp-user] Resizing
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.

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 Gary ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
[Gimp-user] Resizing an imaged - revisted
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 -- HarryA (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
