If you have an Image or a Bitmap object and you want to save it to disc you need to do a couple of steps first.
Here are the examples of the csharp api class SystemDrawingImagingImageCodecInfoGetImageEncoders taken from open source projects. The Quality encoder parameter has values from from 0-100 that will dictate the amount of compression that can be applied for certain encoders 0 for maximum compresssion and 100 for minimum compression. In this case there is only one EncoderParameter object in the array.
An EncoderParameters object has an array of EncoderParameter objects. Never create instance of this type on stack or using operator new as it will result in runtime errors andor assertion faults. Used the full path as below running ok now Dim encoderParam as SystemDrawingImagingEncoderParameter new SystemDrawingImagingEncoderParameterSystemDrawingImagingEncoderQualityquality.

I passed some parameters while saving the image so that the quality is at 100 and there is no compression but the number of actual unique colors go from 254 in the original image to 16in the saved image with a clear loss in qualityinformation even though the image properties show 8bpp. Here are the examples of the csharp api class SystemDrawingImagingEncoderParametersDispose taken from open source projects. Create an EncoderParameters object.
