Lightroom Classic: Add to API: LrDevelopController.quickDevelopAdjustImage smallDecrease and largeDecrease

Hi Rory,

Thanks for sharing the feedback.
We'll consider it.
However, Once can use LrDevelopController.quickDevelopAdjustImage (settingName, size) with a negative number for size to decrease the values.

Thanks,

Right, but in the Library module, you can't check ranges for an adjustment, and different file types have different ranges, so using a number is problematic. Also, not having small/large for decreases misses the benefit of small/large for increases, as a person adjusting a photo would want the ability to overshoot an adjustment and move it back down by the same increment.

Some reverse engineering reveals how to use the photo:quickDevelop* methods to behave like the <<, <, >, and >> buttons in the Quick Develop panel.

photo:quickDevelopAdjustWhiteBalance ("Temperature", n)
photo:quickDevelopAdjustWhiteBalance ("Tint", n)

With n = -5 or 5, these settings increase or decrease the same amount as using the < and > buttons. With n = -20 and 20, they change the same amount as using the << and >> buttons.

photo:quickDevelopAdjustImage ("Exposure", n)

With n = -16.5 or 16.5, Exposure increases or decreases the same amount as using the < and > buttons. With n = -50 or 50, Exposure changes the same amount as using the << and >> buttons.

photo:quickDevelopAdjustImage (setting, n)

For "setting" equal to one of "Contrast", "Highlights", "Shadows", "Whites", "Blacks", "Clarity", and "Vibrance": With n = -5 or 5, the settings increase or decrease the same amount as using the < and > buttons. With n = -20 or 20, they change the same amount as using the << and >> buttons.

* * * 

With all of these, when the settings reach their minimum or maximum value, further attempts to decrease or increase them leave them at the minimum/maximum, just like the <<, <, >, and >> buttons.

And of course, this should all be documented.  

Im praying for you to resolve this matter. I have been waiting to use the complete Quick Develop module with my midi controller for a long time!! haha

Thanks for all
