IMHO ..
only default section is executed in any case.
That is what I thought.
So, the MX3 code is incorrect ?
Also, I have a spotmeter function that shows the average luminance of a 24x16 pixel area in the middle of the screen.
That works for A620 and ixus860, it always shows 255 with the SX200IS.
That is based on MX3's code for calculating byte position in the live viewport.
I have assumed that the byte-order for all viewports is the same.
Is that correct ?
