The \fBMPSImageAreaMax\fP kernel finds the maximum pixel value in a rectangular region centered around each pixel in the source image\&. If there are multiple channels in the source image, each channel is processed independently\&. The edgeMode property is assumed to always be MPSImageEdgeModeClamp for this filter\&.

.SS "\- (nullable instancetype) \fBinitWithCoder:\fP (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device"
\fBNSSecureCoding\fP compatability  While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly\&. To avoid that problem, use initWithCoder:device instead\&. 
.PP
\fBParameters:\fP

\fIaDecoder\fP The NSCoder subclass with your serialized \fBMPSKernel\fP

\fIdevice\fP The MTLDevice on which to make the \fBMPSKernel\fP
