About the Pixel Analyzer |
The Pixel Analyzer is an analysis tool for finding and comparing different color values on your image. You can examine mimimum, average, current, or maximum pixel values on either a selection that you make, or across an entire image. It is particularly useful, naturally, when doing color-corrections.
Drag across an image with the cursor, and the values update in the Analyzer. You can usually use the default settings in the Analyzer, clicking on the color swatch that you want to examine, Curr (Current color value), Min (Minimum color value), Avg (Average color value), or Max (Maximum color value). You can toggle between the differenct color swatches repeatedly without the need to re-drag.
The Analyzer keeps the examined pixels in memory, so if you switch images in the same Viewer, the Analyzer will update its values based on the new image. Because of this, you can compare images, or do color-corrections, as the color correction will constantly update the Analyzer.
Mode
Accumulate
By hitting the Accumulate button, all scrubbed pixels, not just the current pixel, will be considered for Average, Min, and Max calculations until you hit the Reset button. Average will therefore calculate the average of every scrub since the last time Reset was hit, and Min and Max will replace their values if a new minimum or maximum value is scrubbed. If the Analyzer is on Image Mode, this button has no effect.
Reset
Resets the scrubbed buffer to black.
Value Range
Shake describes its color in a range of 0 to 1 (0,0,0 is black, 1,1,1 is white). However, you can set this to a different numerical range, i.e., 0,0,0 is black, and 255, 255, 255 is white. This is only a display setting for the numerical date - the images won't change.
Hexadecimal
Toggles the numerical display to hexadecimal values.
Min/Max Basis
These toggles set the channel for calculation of the Min/Max swatches. Normally, this is set to l, luminance. If, however, you wanted to find the minimum values only in the red channel, you would toggle the Basis to r (red). The difference is if you have a pure red pixel and a pure green pixel. Based on luminance, these are equivalent pixels, but based on red, the green pixel has a minimum value of 0, and so Min would return a different number.
