Hi Scott,
I understand that you would like to set the contrast of the image instead of the default. For this, I would suggest you to use the 'clim' property. This will set the range of the slide in the 'imcontrast' panel. Here is an example for the same:
% Load your image
image_data = imread('gray.png');
% Display the image
imshow(image_data);
% Open the interactive contrast adjustment tool
h = imcontrast(gca);
min_value = 100; % Set your desired minimum value
max_value = 200; % Set your desired maximum value
clim([min_value max_value]);
You can know more about the 'imcontrast' function using the link below:
Hoping this will help in resolving your issue!
