Int nextLine = originalData.Width - width įor (int y = 0, i = 0 y srcPixels = new Span((void*)originalData.Scan0, originalData.Width * originalData.Height) įor (int y = 0, i = 0, s = left + originalData.Width * top y < height y++, s += nextLine)įor (int x = 0 x < width x++, i++, s++) Int* srcPixel = (int*)originalData.Scan0 + (left + originalData.Width * top) Unsafe public static Bitmap Crop(this Bitmap bitmap, int left, int top, int width, int height)īitmap cropped = new Bitmap(width, height) īitmapData originalData = bitmap.LockBits(new (0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, bitmap.PixelFormat) īitmapData croppedData = cropped.LockBits(new (0, 0, width, height), ImageLockMode.WriteOnly, bitmap.PixelFormat) If cropping to a 1000x1000 image they are about the same speed.īenchmarks are below if interested. I've included 2 versions, one uses Span, which is slightly more performant when cropping to a smaller image. (Other formats could work as long as 1 pixel is stored as 4bytes) Just keep in mind 32bpp is the only format the methods support. Graphic.DrawImage(OriginalImage, new SD.Rectangle(0, 0, Width, Height), X, Y, Width, Height, SD.GraphicsUnit.Pixel) įor anyone willing to use "unsafe" code, you can achieve much better performance than the standard method, and even better if you are using Bitmap.Clone(). Graphic.PixelOffsetMode = PixelOffsetMode.HighQuality Graphic.InterpolationMode = InterpolationMode.HighQualityBicubic Graphic.SmoothingMode = SmoothingMode.AntiAlias Using (SD.Graphics Graphic = SD.Graphics.FromImage(bmp)) Using (SD.Bitmap bmp = new SD.Bitmap(Width, Height))īmp.SetResolution(OriginalImage.HorizontalResolution, OriginalImage.VerticalResolution) Using (SD.Image OriginalImage = SD.Image.FromFile(Img)) ![]() Static byte Crop(string Img, int Width, int Height, int X, int Y) ImgCropped.ImageUrl = "images/crop" + ImageName String SaveTo = path + "crop" + ImageName ĬroppedImage.Save(SaveTo, CroppedImage.RawFormat) Using (SD.Image CroppedImage = SD.Image.FromStream(ms, true)) Ms.Write(CropImage, 0, CropImage.Length) Using (MemoryStream ms = new MemoryStream(CropImage, 0, CropImage.Length)) String ImageName = Session.ToString() īyte CropImage = Crop(path + ImageName, w, h, x, y) Protected void btnCrop_Click(object sender, EventArgs e) ImgCrop.ImageUrl = "images/" + Session.ToString() LblError.Text = "Cannot accept files of this type." LblError.Text = "File could not be uploaded." + ex.Message.ToString() String allowedExtensions = įor (int i = 0 i < allowedExtensions.Length i++) String FileExtension = Path.GetExtension(Session.ToString()).ToLower() Protected void btnUpload_Click(object sender, EventArgs e) Protected void Page_Load(object sender, EventArgs e) the subimages to the output image using GraphicsĬroppedImage.SetPixel(x, y, atlasImage.GetPixel(t.x + x, t.y + y)) ĬroppedImage.Save(Path.Combine(workingFolder, t.name + ".png"), ImageFormat.Png) Ĭ# code logic for upload and crop. copy pixels over to avoid antialiasing or any other side effects of drawing height of the texture in the atlas imageīitmap atlasImage = new pixelFormat = atlasImage.PixelFormat ĬroppedImage = new Bitmap(t.width, t.height, pixelFormat) width of the texture in the atlas image y position of the texture in the atlas image x position of the texture in the atlas image So later i managed this way and needed 2,43 sec to do the same job. I tried Nicks solution, but i needed 29,4 sec to "extract" 1195 images of an atlas file. I was looking for a easy and FAST function with no additional libary to do the job. ![]()
