For example,

xx.ppm has 10bit data format

when I use a = imread("xx.ppm")

'a' file's data has multiplied by 64, because MATLAB Imread ppm default data format is 8bit unit

More exactly, If a files axis(1,1) origianl data is decimal 10 but In Matlab Imread, that data is changed decimal 640.

But I want using 10bit data format.

How can I change ppm image data unit format when I Using Imread?

please help me,

I'm sorry for the lack of readability because My English skill are not good

Thanks for reading.

Sorry My English skill are poor

It's mean, xx files loading data 'a' has muliplied by 64,

xx files original data (view by using notepad) is 10 (10 bitdepth)

but matlab is forcibly change 16bitdepth(uint16) format.

So data is changed 10(In Notepad) --> 640 (In Matlab)

I want my ppm data format has 10 bit depth
