GUI for Geometry

[x0054]

Hi guys,

I was wondering, are there any Windows GUI plugins for ImageMagick? What I mean is, for instance, I would like to write a small batch script that preforms a few actions on a set of pictures in a folder. One of the things I need to do is crop all the pictures in that folder in a certain way. Basically, these pictures are photos of biological cells taken under microscope for research. So, one folder would contain 6-10 photos of the same cell but under different fluorescent lights. Because the area to be cropped out is different for every sat of images, currently I have to figure out the geometry by hand every time before running the script.

It would be cool if I can instead write a script like so:

IMHelper convert folder\*.jpg -crop ++geometry++ folder\out-*.jpg

IMHelper would be an interpreting program, it would run through the script supplied to it, when it encounters ++geometry++ it would popup a preview window with first picture from the source, and let me select the cropping area. Then it would pass those values to imagemagic. I searched and searched, and could not find anything like this. If it already exists, could someone point me in the right direction. And if not, maybe someone wants to write it I would my self, but I would not know were to begin with real programming

I can also see such as "IMHelper" having other GUI functions, such as ++source-files-drop++ would show a dropbox into which one could drag files, or ++out-files++ would show a save as dialogue. All kinds of interactive plugins basically can be added to interact with im scripts.

Any ideas or suggestions for my specific problems? Any comments on the idea presented above?

Thanks in advance for any help!

There have been a couple of attempts at Windows GUI but they seem to have disapeared.

You can check this thread: viewtopic.php?f=1&t=18219&hilit=gui
I belive the OP was looking for some testers but it has to be on windows 64bit

You can use IrfanView as a geometry GUI for ImageMagick. You can do that by way of an AutoHotKey script that performs some action based on your selection in IrfanView. (BTW: IrfanView can of course do a batch crop by itself.) Here is an AHK-Script that marks the selected area in the original photo and extracts that area from the photograph. I provide it as-is (with German comments). I will incorporate this example on my Windows Usage page in the future (see link below).

nip2 runs fine from Windows (I'm told: not a windows user).

On Windows and OS X, nip2 includes its own copy of ImageMagick, so there are no other packages to install.

I don't know if this works from Windows, but you could use display http://www.imagemagick.org/Usage/basics/#display http://www.imagemagick.org/www/display.html to immediately show the result of your IM operation, on the same command line.
So, it would not be a GUI, but you could tweak the crop value on the command line, press return, see the result, kill the display (in unix, <CTRL>-C would do it from the command line), "up arrow" to recall the last command line, and edit to taste for another go.
With a bit of practice, almost certainly faster than using a GUI, because you'd do everything from the shell (DOS terminal, I imagine), without every moving your hands from the keyboard.
(From MinGW? Cygwin? I don't really know: sheltered *n*x snob here.)

Something like

Code: Select all

   convert image.jpg -crop  `im_geometry image.jpeg` result.png

should work very well (UNIX, or Cgiwin), but I don't know of any.


I myself use "xv" with a 'info' window to select regions. But I have to manually type the geometry result
For points I use display with its magnifier, mostly to get 'colors' for remapping.

Something like this built into IM would be useful with IMv7 "magick" scripting.
Also a 'multi-point picker' with magnification for exact pixel/color selection, perhaps even sub-pixel positioning would also complement things.

Problem the "display" program under windows is also in need of a developer. Or so I believe, as I am not a Windows user.

Gimp can be used as a GUI driver for IM, rather clumsily. True, I'd like Gimp to build a batch file of IM commands that I could run at my leisure, but doing that is probably harder than making Gimp 16-bit. In the meantime, we can:

1. Use Gimp curves tool to adjust tones, colour balance etc. Then use Gimp to apply the same curve to a gradient file that IM can use for CLUT. This is easy and real magic -- I can easily see the effect of subtle changes to the curve in Gimp, leaving IM to do the 16-bit work.

2. Use Gimp to decide on a crop and save it. Then IM can work out the cropping parameters and apply that to a 16-bit file. This is actually a tricky problem for IM. We can use "compare -metric RMSE -subimage-search", but this takes too long for 36M pixel files. The trick is to make tenth-size copies (-resize 10%) of the original and the crop. IM can quickly find this crop within this image, so now we know the position within about 10 pixels for the full-size image and crop. This lets us narrow the search for the full-size crop within the full-size image, so that is also fast.

You can also do compount color processing in GIMP on an HALD image. Create the unprocessed HALD image in IM, process it in GIMP, then bring the modified HALD image back to IM and use it to apply to many images. Note the HALD technique does not work with spatially dependent processing such as convolution, blur, sharpen or resize/distort. see http://www.imagemagick.org/Usage/color_mods/#hald-clut

This is the exact trick I use in some of my scripts to speed up the subimage search with compare.

Ah, great minds ... In theory, the tenth-size trick might generate a false positive, but it works for me.

Agreed!

In principal, one could do it on a factor of 2 pyramid. I thought about that, but decided it was too much work.
