Usage Examples:

IMAGINGNET-6558 Required palette is missing exception loading BMP

using var image = Image.Load(@"Texture.bmp");
image.Save(@"output.png");

IMAGINGNET-6466 The GIF file loading issue

using var image = Image.Load(@"input.gif");
image.Save(@"output.png");

IMAGINGNET-6428 Exception on creating palette of large image

using var image = Image.Load("large-tiff.TIFF");
var bpp = 8;
var colorPalette = ColorPaletteHelper.GetCloseImagePalette(image, 1 << bpp); // does not throws exception

IMAGINGNET-6410 DICOM load issue

using var image = Image.Load("0008cc0a_niming.dcm");
image.Save("0008cc0a_niming.jpg");

IMAGINGNET-6285 Implement Remove watermark filter

var imageFilePath = "ball.png";
var outputFilePath = "result.png";
using (var image = Image.Load(imageFilePath))
{
    var pngImage = (PngImage)image;

    var mask = new GraphicsPath();
    var firstFigure = new Figure();
    firstFigure.AddShape(new EllipseShape(new RectangleF(350, 170, 570 - 350, 400 - 170)));
    mask.AddFigure(firstFigure);

    var options = new ContentAwareFillWatermarkOptions(mask)
    {
        MaxPaintingAttempts = 4
    };

    var result = WatermarkRemover.PaintOver(pngImage, options);

    result .Save(outputFilePath);
}
