Kelas : PBO - B


1) RANCANGAN INTERFACE

2) CLASS

Penjelasan :

Class :

• Class ImageViewer : Untuk menjalankan program dan menggabungkan semua kelas
• Class ImagePanel: Menampilkan OFImage
• Class ImageFileManager : Membuka dan menyimpan gambar
• Semua Filter : Membuat filter gambar sesuai dengan namanya antara lain (DarkerFilter, EdgeFilter, FishEyeFilter, MirrorFilter, LighterFilter, SolarizeFilter, GrayScaleFilter, InvertFilter, ThresholdFilter, SmoothFilter, PixelizeFilter.)

Menu Tools :

• Add Text : Menambahkan tulisan pada gambar yang sudah di buka
• Crop : Memotong gambar

Menu Fitur :

• Rotate : Rotate right 90 drajat, rotate left 90 derajat, dan rotate 180 derajat. Untuk memutar gambar sesuai dengan keinginan
• Zoom : zoom in (memperbesar gambar) dan zoom out (memperkecil ukuran gambar)
