opsi
Tidak dapat disimpan ke format yang ditentukan karena tidak didukung pada saat ini.;optionsBase
Ekspor gambar gagal.
SetPalette(Tembakau dan Bool)
Menetapkan palet gambar.
public abstract void SetPalette(IColorPalette palette, bool updateColors)Parameters
palette IColorPalette
Palet yang harus ditentukan.
updateColors bool
Jika ditetapkan pada warna ‘kebenaran’ akan diperbarui sesuai dengan palet baru; jika tidak indeks warna tetap tidak berubah. perhatikan bahwa indeks yang tidak berubah dapat merusak gambar pada muatan jika beberapa indeks tidak memiliki entri palet yang sesuai.
UpdateContainer(Image)
Mengemas kini kontena.
protected void UpdateContainer(Image container)Parameters
container Image
dari container tersebut.
