I don't understand this...

[J_Y_C]

So, I have a condition to test, that a pixel color is in a certain value range. When I use an "IF" statement to perform the test, it doesn't work, but if I use a switch statement, it does. Check it out:

This works:

$swVal = PixelGetColor($x, $y)

Switch ($swVal)
    Case ($RED-100000) To ($RED+100000)
        $lineState[$LN - 1] = 2
        Return True
EndSwitchoÝ÷ Ù8b±Ú²z-jëh×6$swVal = PixelGetColor($x, $y)

if ($swVal>($RED-100000)) then
        if ($swVal<($RED+100000)) then
        $lineState[$LN - 1] = 2
        Return True
        endif
endif

It seems to me that these should test the same, but they don't. Any ideas on why this is? The code works with the Switch statement, but it seems wanky to me, and I want to understand _why_.

Thoughts?

Edit: The "enclosing" parentheses don't seem to be an issue with another test script I did, but again... I'm grasping here

Gee, I found this problem yesterday, and now that I come back to it all 3 method work.

woof.

I need some rest, I guess. Sorry for wasting your time, I should have re-checked again today.

Solution probably looked like:

$swVal = PixelGetColor($x, $y)

if ($swVal >= ($RED-100000) AND $swVal <= ($RED+100000)) then
        $lineState[$LN - 1] = 2
        Return True
endif
