Resizing Images (was: How much time does it take to manage a group?)
|
Ken KM4NFQ
Thank you for your reply Duane.
?
My Nikon CoolPix digital camera takes huge photos.
I used to save them in a directory, and it didn't take long to reach an astronomical size.
Now I only save resized images to disc.
Compare: 4608x3456+0+0 8-bit sRGB 3.86798MiB
to: 849x561+0+0 8-bit sRGB 656352B
3.8MB to 0.6MB
?
So I am now working with resized images 99% of the time.
I simply open the original image in a browser which automatically resizes it to fit in the window.
I can use Ctrl-plus or Ctrl-minus to get the size I want.
Then I use a screenshot program to select the area I want to grab, and make a new image.
?
It doesn't take much time at all, and I am managing my disc space much better.
Plus, I find that I rarely look back. That is, I hardly ever look at those saved images again.
And if I do find myself looking through back-up discs for images, if I find it, I resize it as described above.
?
I guess that is the main thing. I used to think that I needed to save 'everything.'
It just does NOT seem that important to me anymore.
I am pretty sure it has something to do with time? ;-D
?
One other thing that I have discovered is that there is just so much information that can be discovered in an image. It seems that the closer I look at an image, the less I see. Go figure.

Ken, Flexxi - Batch Image Resizer?

Hello Bret, I use the Debian GNU/Linux operating system. Graphics programs that I have on my system are: Kolourpaint4 GIMP Inkscape ImageMagick I usually have a browser open on one of the four desktops. After downloading the image from the digital camera, I open an image in the browser. Ctrl-O [ path to image/image_name ] The image opens, resized to the browser window. I can zoom in or out with Ctrl-plus or Ctrl-minus, and center the area I want to grab with scrollbars. Then I press the PrtScr button on my keyboard. The screenshot program opens. I choose Select Area To Grab and press the Take Screenshot button I use my mouse to grab the area that I want - various sizes - sometimes small, sometimes larger. I can type in a new filename for the new image, or accept the default. The resized image is automatically saved in the Pictures directory. Really, it is very fast and easy. It took way longer to describe it than to do it. I have muscle memory for doing it. I use the Firefox ESR browser. If I need a slightly larger image, I press F11 to go fullscreen on the browser. I usually I use this browser method for one-off images that I want to include in an email or a post to a forum. I can do batch operations on similar images using the convert utility from ImageMagick. j=2001; for i in {1001..1024}; do convert -crop 343x767+341+1! ${i}.png ${j}.png; let j++; done That command took screenshots that were opened in the browser and saved as Grab the whole window (1024x768). The original images were 3558x7411+0+0 pixels in size. They were cropped to 343x767 pixels in size. Then I used a command-line utility to animate the images. But I could also resize the original images using convert, with a similar bash shell command: j=2001; for i in {1001..1024}; do convert -resize 10% ${i}.JPG ${j}.png; let j++; done That convert utility from ImageMagick is the bee's knees! 24 images is about the most I ever have to do at any time. ;-D I guess Kolourpaint4 is similar to Paint? It is a raster graphics program with simple features. I have not used MS-Windows for over 23 years, so I don't really know for sure? Also, I do not know anything about MAC OSX. Both MAC and MS-Windows are extremely proprietary systems. Inkscape is a vector graphics program. The GIMP is similar to PhotoShop? That is what I've heard. I do everything that I need to do on a computer with Free Open Source Software. Regards, Ken, KM4NFQ "Not Fully Qualified" On Sun, Nov 17, 2019 at 3:59 PM bret <bmaverick@...> wrote:

There's also the free Irfanview that lets you resize by percentage,
dpi, or pixels. Simple, easy to figure out and use, and small in size. Nothing too fancy--it's not a Photoshop--but it can make some enhancements as well. It's been around a long time and keeps improving, and the price is right!

This will usually drop the image size down below half the original size. Should you need to go smaller, use the 640 for pixel size or the smaller 480. ---------------------------------------------------- Join the Icom group, a general Icom (amateur radio) discussion group on Groups.io: /g/ICOM (recently launched, growing slowly) **also, a new self-help group dedicated to your cat's health: /g/CatVet (just launched) |

That's fine but of no help when other members decide to upload photos. It's much better to get the "uploading" resizing setting right and that will keep everybody's photos to a sensible size. Chris |

Hello Chris, I agree. That is why I have images set to resize to 488x488. Regards, Ken, KM4NFQ "Not Fully Qualified" On Sun, Nov 17, 2019 at 5:02 PM Chris Jones via Groups.Io <chrisjones12=[email protected]> wrote: On Sun, Nov 17, 2019 at 09:49 PM, Ken KM4NFQ wrote: |
