and select Pixel Analyzer.The analyzer’s full frame mode samples the visible region of the Viewer by default. As a result, actions that change the visible area, such as zooming in and out, alter the available color values.
NOTE: Enabling full frame processing forces the Pixel Analyzer to analyze the entire frame, regardless of the portion of the Viewer currently visible.
| 1. | Connect a Viewer to the output you intend to analyze. You can connect multiple Viewers to a single output, and vice-versa, for comparison. |
| 2. | Click the contents menu and select Pixel Analyzer. |
The Pixel Analyzer panel displays.
| 3. | Use the sample dropdowns to control which Viewer and layer provides the swatch information: |
• viewer - the default, current viewer, always samples the active Viewer if there is more than one. Selecting pixels in a Viewer or clicking on a Viewer’s tab causes the Viewer to become the active or current Viewer. Alternatively, you can select a named Viewer from the dropdown when more than one is open.
• layer - the default, current layer, displays the layer(s) specified in the Viewer channels dropdown.
NOTE: If rgba channels are not present, the first four available channel values are written into the Pixel Analyzer’s rgba controls.
NOTE: The color swatches may not update immediately if you select a layer from the sample dropdown that is not currently visible in the Viewer, because the new layer must be rendered in the background before the swatch is calculated.
Alternatively, you can select a named layer from the dropdown. When switching between Viewers, the Pixel Analyzer attempts to match the selected layer in the new Viewer. If that layer doesn't exist, the default current layer is displayed.
TIP: You can use the layer dropdown to sample a layer that is not displayed in the Viewer, allowing you to compare position and color values between layers.
| 4. | Ensure that the mode dropdown is set to full frame. |
| 5. | Click on the swatches to display rgba and hsvl color values for the selected swatch. |
The Pixel Analyzer also detects inf (infinite) and nan (not a number) color values. The ! point in the swatch indicates inf/nan values.
| 6. | Use the range dropdown to select the color bit-depth you intend to display. For example, selecting 8-bit limits your color values to 255. |
| 7. | Set the min/max channel you want to use to calculate the min/max color swatches. |
This control defaults to luminance (l), but if you wanted to display the minimum values in only the red channel, for example, you could set min/max to red (r).
