c# - Convert Simpleitk image into BItmap. System.ArgumentException -

i want read dicom image using simpleitk, convert bitmap , display result in picturebox. when i'm trying this, argumentexception thrown. how can solve this?

here code:

openfiledialog dialog = new openfiledialog(); dialog.title = "open"; dialog.filter = "dicom files (*.dcm;*.dic)|*.dcm;*.dic|all files (*.*)|*.*"; dialog.showdialog(); if (dialog.filename != "") {     using (sitk.imagefilereader reader = new sitk.imagefilereader())     {         reader.setfilename(dialog.filename);                            reader.setoutputpixeltype(sitk.pixelidvalueenum.sitkfloat32);         sitk.image image = reader.execute();          var castedimage = sitk.simpleitk.cast(image,              sitk.pixelidvalueenum.sitkfloat32);         var size = castedimage.getsize();         int length = size.aggregate(1, (current, i) => current * (int)i);         intptr buffer = castedimage.getbufferasfloat();          // declare array hold bytes of bitmap.                             byte[] rgbvalues = new byte[length];          // copy rgb values array.         marshal.copy(buffer, rgbvalues, 0, length);          stream stream = new memorystream(rgbvalues);          bitmap newbitmap = new bitmap(stream);          //i have tried in way, generated argumentexception         //bitmap newbitmap = new bitmap((int)image.getwidth(), (int)image.getheight(), (int)image.getdepth(), pixelformat.format8bppindexed, buffer);          obraz.pic.image = newbitmap;     } } 

thank comments , attempts help. after consultations , own searching on internet solved issue. first problem inadequate representation of pixel image. had change float32 uint8 provide eight-bit pixel.

var castedimage = sitk.simpleitk.cast(image2, sitk.pixelidvalueenum.sitkuint8); 

then create bitmap using constructor was commented out in question, (int)image.getwidth() instead of (int)image.getdepth().

bitmap newbitmap = new bitmap((int)image.getwidth(), (int)image.getheight(), (int)image.getwidth(), pixelformat.format8bppindexed, buffer); 

unfortunately, new problem appeared. image, supposed in gray scale, displayed in strange colors. found solution here

colorpalette pal = newbitmap.palette;                 (int = 0; <= 255; i++)                 {                     // create greyscale color table                     pal.entries[i] = color.fromargb(i, i, i);                 }                 newbitmap.palette = pal; // need re-set property force new colorpalette
