我正在尝试使用指定的调色板创建 3x1 位图。为了测试,我使用了 3 种颜色:红色、绿色和蓝色。当我运行我的代码时,我得到的都是红色(这是第一种颜色)。
这是我的代码
public void CreateTestImg()
{
// List to store colors for palette
List<Color> Colors = new List<Color>();
// Adds Red to the list
Colors.Add(Media.Color.FromArgb(255, 255, 0, 0));
// Adds Green to the list
Colors.Add(Media.Color.FromArgb(255, 0, 255, 0));
// Adds Blue to the list
Colors.Add(Media.Color.FromArgb(255, 0, 0, 255));
// Create a new palette with the list of colors as input
BitmapPalette PLT = new BitmapPalette(Colors);
// Make a Bitmap with the specified width, height, dpix, dpiy, pixelformat, palette, PixelData, stride.
BitmapSource wb = BitmapSource.Create(3, 1, 96, 96, PixelFormats.Indexed8, PLT, {0, 1, 2}, 3);
// Freezes the object
wb.Freeze();
// Creates a new brush from the Bitmap so I can draw with it later
ImageBrush newBMB = new ImageBrush(wb);
// Freezes the brush
newBMB.Freeze();
// Adds brush to dictionary for later referencing
ImageBatch.Add("WHATEVER", newBMB);
}
