Contoh

Contoh ini menunjukkan konversi format gambar PSD ke Color Modes/BitDepth lainnya.

[C#]

string dataDir = baseFolder + Path.DirectorySeparatorChar;
string outputDir = dataDir + "output" + Path.DirectorySeparatorChar;

// Contoh ini mendemonstrasikan konversi format gambar PSD ke Color Modes/BitDepth lainnya.

ImageConversion(ColorModes.Grayscale, 8, 2);
ImageConversion(ColorModes.Grayscale, 8, 1);
ImageConversion(ColorModes.Rgb, 8, 4);
ImageConversion(ColorModes.Rgb, 16, 4);
