rgb statistics of an 24bit bitmap

[Simon790]

Hello

I try to analyse the RGB values (max, min, mean, ect) of a 24bit bmp. i found a way to represent the pixelvalues as 24bit values in an array.

then i convertet the array into a dynamic signal. since the 24bit consists of 3 Bytes which represent the values of each rgb-channel i need to splitt this 24 bit into bytes. I found a VI vich changes the color format into rgb. the problem now is that the resulting values are single scalar which i really cant analyse with the signal analysing tool. i always get the same values for mx, min and mean, that means only one scalar value ist analysed.

How can i achive that the whole 2bit signal is splittet into byte-pieces in signal form?

can somebody help me? 

Thank you very much!

Hi Simon,

maybe you can stick to your RGB data without converting to 'dynamic signal'. Just have a look at the attached vi, it's just pure arithmetic to get the color channels.
Other simple method would be to put 'Color to RGB' into 2 auto-indexing for-loops (without conversion to dynamic in front) to split the color channels.
