Adding CurvePoints to existing Curve

Michael Wilmes

• February 28, 2020 12:07

It's seems like every image has preexisting curves in C1 with two CurvePoints set by default as a curve is a straight line with two points by default. I'm however now struggling in identifying proper means of adding CurvePoints via JXA or AppleScript. Does anyone have a JXA or AppleScript example on how to add an element?

Thank you in advance.

  Hi Michael,
  
  I'm probably a bit late to answer. But in case you still need the info, here is a sample using AppleScript:
  
  tell application "Capture One 20"
set selectedVariants to (get selected variants)
tell document in front
-- CHECKS IF ANY VARIANT IS SELECTED
if selectedVariants is {} then
display dialog "No selected variant. Please select variants and try again."
else
-- LOOP TO APPLY SETTINGS TO ALL SELECTED VARIANTS
repeat with thisVariant in selectedVariants
tell adjustments of thisVariant

-- DEFINE VALUES FOR RGB CHANEL
tell rgb curve

-- SET VALUES FOR DEFAULT (0;0) POINT
-- !! VALUES ARE DEFINED ON a 0-100 SCALE, NOT 0-255
set brightness of first curve point to 0
set amount of first curve point to 5

make new curve point with properties {brightness:18, amount:14}
make new curve point with properties {brightness:50, amount:55}
make new curve point with properties {brightness:85, amount:87}

-- SET VALUES FOR DEFAULT (100;100) POINT
set brightness of last curve point to 100
set amount of last curve point to 95

end tell

-- DEFINE VALUES FOR RED CHANEL
tell red curve

-- SET VALUES FOR DEFAULT (0;0) POINT
set brightness of first curve point to 2
set amount of first curve point to 0

make new curve point with properties {brightness:50, amount:45}

-- SET VALUES FOR DEFAULT (100;100) POINT
set brightness of last curve point to 100
set amount of last curve point to 98

end tell
end tell
end repeat
end if
end tell
end tell
