I used java swing to write an image tagging tool.

Function Description:

1. CLICK: select the cropping area.

2. Double Click: select the cropping area, save the cropping area as a file, and save the coordinates of the center of the area.

3. Open an image: Open the image from a folder and display it. At the same time, upload the paths of all the images in the directory. This function is mainly applicable to such situations,

If you process the image set of a folder and it is terminated or paused, the next time you start from the image. <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4KPHA + NCCxo7Tm1/release/CvLXEy/release + release/qsS/release + release/KjrLGjtObX + release/release + release/J0tTA + 9PDobC08r + release + examples/examples + cve-vcd4kpha + examples/ix6qGxus2hsM/examples + cve-vcd4kpha + z8LD5ri9yc/utlt6wuujuw.vcd4kpha + PGJyPgo8L3A + placement = "brush: java; "> import java. awt. borderLayout; import java. awt. color; import java. awt. container; import java. awt. dimension; import java. awt. flowLayout; import java. awt. graphics; import java. awt. gridLayout; import java. awt. image; import java. awt. toolkit; import java. awt. event. actionEvent; import java. awt. event. actionListener; import java. awt. event. keyEvent; import java. awt. event. keyListener; import java. awt. event. mouseAdapter; import java. awt. event. mouseEvent; import java. awt. image. bufferedImage; import java. awt. image. cropImageFilter; import java. awt. image. filteredImageSource; import java. awt. image. imageFilter; import java. io. bufferedWriter; import java. io. file; import java. io. fileNotFoundException; import java. io. fileOutputStream; import java. io.
