Legacy ImageMagick Discussions Archive

Hi,

i have a little bit complicated question and i hope i can explain what i want.

i have a lot of comic books scanned and want to crop and resize them to be readable on my tablet. at the moment i use xnview with batch mode, but rotation results in a bad text quality and at the moment there is no option to use a better "resize method". i do the same options to all input files in this order: rotate, crop, auto-crop. if necessary i rotate the image. if auto-crop has cropped all parts around the box i don't use crop, if auto-crop doesn't work correctly (sometimes there are some 'dots' on the paper so that auto-crop thinks this is a part of the image, it stops cropping at that 'dot') i use crop only to crop at this side. here the 'live preview' is very helpful because i can increase the crop value and see when its enough. if the 'dot' is cropped auto-crop works correctly.

can i do the same with image magick? i know there isn't a gui. is there any other way to do this? i imagine something like one preview windows where i see the input file and an other window where i can edit the three options (rotation, crop, auto-crop). when i change something the preview is also changed. if all is ok i click i go to the next image, if it fits with the same settings i go to the next and so on. then i save the cropped and rotated images.

What is your platform? On Windows 8.1, I can run a command like ... ... and open out.png in a viewer sush as Microsoft Photo Viewer. When I re-run the command with different options, the viewer automatically refreshes the image on the screen.

This is a feature of Windows, not ImageMagick.

I'm on ubuntu. Is there no preview Funktion in IM?

Other idea. Can i create a little GUI only to edit the options Rotation, crop and autocrop? Wen something is changed IM creates a New file. As you porposed i could open the New files in an extra image viewer. The image viewer should then reload the image every time the image is changed.

I think the major Problem is the GUI. I'm thinking about doing this with yad or zenity. But i have not enough experience with both programs.

Imagemagick has a GUI with X11 on Linux.

You mean the command display? This is not want im searching for.

Once the image is displace on X11, you can click on it and it will open a GUI to do more processing. Is that what you want. If not, then I do not have any other suggestions. You can create an entry in your delegates.xml file to display an image with some other viewer.

Do you mean the command 'display'? How can i open the image with x11?

Use display, then click on the image. I do not recall which button as Mac no longer supports X11 and it does not work any more in XQuartz. But I think X11 on Linux is still available.

It works fine with XQuartz on my Mac. Use display, then left-click the image to get the menu.

You are correct. My mistake. I had not used that in a while. What I have trouble with is getting coordinate measurement features that used to exist. But perhaps I do not recall the key options to use along with the right mouse button to initiate that mode. Does it work for you?

I never do this, but a little experimentation:

1. Right-click alone gets me a short list of shortcuts.
2. Option-right-click gets me a new window with 3x magnification and as long as I don't let go, I can move around the image with it. The coords of the pixel under the cursor are given in the new window.

That is what I cannot get to work. Perhaps I have a shortcut involving option- that interferes.
