c# - BlobCounter unsupported pixel format -


i getting current exception:

unsupportedimageformatexception: unsupported pixel format of source image. aforge.imaging.blobcounter.buildobjectsmap (aforge.imaging.unmanagedimage image) aforge.imaging.blobcounterbase.processimage (aforge.imaging.unmanagedimage image) aforge.imaging.blobcounterbase.processimage (system.drawing.imaging.bitmapdata imagedata) aforge.imaging.blobcounterbase.processimage (system.drawing.bitmap image) cam.blobcounter (system.drawing.bitmap videooutput, aforge.imaging.blobcounter bc) (at assets/scripts/cam.cs:127) cam.update () (at assets/scripts/cam.cs:69)

which caused blobcounter not accepting current image format. fix used convertion method: bitmap yellowclone = aforge.imaging.image.clone(originalbm, system.drawing.imaging.pixelformat.format32bppargb);

but still error(despite trying every format available).

for context, here code, originalfeedtexture being webcam feed:

byte[] bytes = originalfeedtexture.encodetojpg();         using (var ms = new memorystream(bytes))         {             originalbm = new bitmap(ms);         }          bitmap yellowclone = aforge.imaging.image.clone(originalbm, system.drawing.imaging.pixelformat.format32bppargb);  yellow = new bitmap(yellowclone); yellowfilter(yellow); blobcounter bc = new blobcounter();         blobcounter(yellowclone, bc);         rectangle[] rects = bc.getobjectsrectangles();          if (bc.objectscount >= 1)         {             debug.log("swedes");         }

my yellowfilter function:

 void yellowfilter(bitmap videooutput)     {         hslfiltering yellowhslfilter = new hslfiltering();         yellowhslfilter.hue = new intrange(40, 70);         yellowhslfilter.saturation = new doublerange(0.3f, 0.9f);         yellowhslfilter.luminance = new doublerange(0.3f, 0.8f);          yellowhslfilter.applyinplace(videooutput);     }

and blobcounter function: 

void blobcounter(bitmap videooutput, blobcounter bc)     {         bc.objectsorder = objectsorder.size;         bc.processimage(videooutput);     }

edit: forgot mention, error on following line: blobcounter(yellowclone, bc);

i fixed issue changing version number of aforge.net. tested on multiple versions, , seems when using exact code, issue appears on 2.0.0 version.
