I was not completely clear :'-( so here some more info.
I have no real experience with Swing and had an itch to scratch.
That is why I wrote this program: to get some experience with
Swing and get a little tool to make my live a little easier.
At the moment it is the first try: there is a lot that could be done
much better, but at least this makes live a little easier for me.
The problem is that I like to crop part of a photo to post on
Instagram. For example:
https://www.instagram.com/p/BIGN8pjACDT/
and:
https://www.instagram.com/p/BIGNtrpAmnT/
The first is not perfect, because the leg of the frog is cut of, but I
want to have a one on one crop to keep the quality of the picture. (Or
a 2, 3, 4 on 1 crop, but that is for a next step.)
To show what I mean see the picture in the link. Sometimes a picture says
more as a thousand words. ;-)
https://drive.google.com/file/d/0BzW5q7uL-6z0XzNJb0FSRFFxMDA/
Gimp does not work (at least for me), because I have to crop exactly a
piece of 1080x1080. I do not know how to do this with Gimp. Also when it
is not correct I need to draw again, with the program I have just to
move the cursor a little and click again. Would be better when I could
drag the square, but again: this is just my first try.
A rundown of what the program does:
When it starts it asks for a graphic file to be displayed. It displays
this with both the width and height divided by eight because I want to
see the complete picture.
The program displays a square of 135x135 in the upper left corner. When
multiplied by 8 this gives the wanted 1080x1080.
By clicking in the picture the square is moved to select the part of the
picture I want to crop.
By clicking on crop a file is selected to save the selected area and the
saved part is displayed. The displaying of the selected part is done
without re-sizing because I want to see exactly what I did select and it
can almost be displayed on my screens.
If I am satisfied with the cropped image I can click load to start with
the next picture.
What needs to be improved:
- It should be system independent. For me pack did not work, so I put
things on a hard coded position. This will probably be no problem when
it is run on another Linux machine, but could wreck havoc on a Windows
machine.
- I should know if the image is rotated, so I could rotate the cropped
image also. Maybe this is not really important, because I am thinking
about putting all pictures in a SQLite database and then the rotation
will also be stored.
- After loading an image the first click results in flicker. This should
be solved.
- I want to have the possibility to add comment to the picture. (EXIF)
- It now only works with the primary dimensions of Instagram, but it
should also work with the other two. After this it should also work
with the dimensions of the other Social Media and it should be
possible to add your own custom dimensions. (SQLite to the rescue.)
- Possibility to resize. (Select an area of 2.160x2.160 and crop it to
1.080x1.080).
- Instead of clicking it should work with dragging the square (or
rectangle).
- Probably a lot of other things. :-D I am open to suggestions.
