Where Is The Ruler Tool In Photoshop Cc

Ruler tool

The ruler tool lets yous measure distances and angles in an epitome. To draw a measuring line, make sure the Info panel and/or ruler tool options bar are visible and click and drag with the ruler tool in an prototype certificate window. After y'all have dragged the ruler tool to make a measurement, the measurement units will appear in the ruler options bar like the example shown below in Figure 1. You tin can and then click on the Clear push button to clear the current ruler measurement.

Figure 1 Here is a view of the ruler tool options bar where I made a measurement with the ruler tool. The ten y readouts betoken the start point coordinates for the ruler tool measurement and the W and H readouts signal the width and height of the ruler measurement. The units displayed here utilize whatever units are currently set for the ruler preferences. Annotation that the 'Use Measurement Scale' option is only available in the extended version of Photoshop.

Figure 2 Here is another view of the ruler tool options panel for the Extended version of Photoshop. In the instance shown here the 'Employ Measurement Scale' option was checked. In this mode, the ruler tool displays the measurement units using the Measurement Calibration settings. This can exist accessed by going to the Image menu and choosing Analysis Set up Measurement Scale Custom… Y'all can utilise this dialog to create a custom measurement scale setting where logical unit of measurement lengths can be given a name such every bit inches or pixels and yous can gear up the pixel length for each unit of the logical calibration. In the example shown here, I created a setting where 10 pixels equaled a one cm unit of measurement of length.

Protractor mode

The ruler tool also has a protractor fashion. Subsequently cartoon a measuring line, Selection/Alt-click on one of the finish points and elevate out a second measuring line. As you lot drag this out, the angle measurements are updated in the ruler tool options bar and Info panel. Notation that the ruler tool line merely remains visible when the tool is selected (or you can hide it with the View Hide Extras command). The ruler tool line tin be updated at any time by clicking and dragging any of the end points. And as with other tools, the ruler tool can be made to snap to the grid or guides.

Straightening images

With previous versions of Photoshop, the ruler tool could exist used to measure the angle of say, an horizon in a photograph and apply this measured angle to rotate the image choosing Image Image Rotation Arbitrary. You tin can however apply this method if you wish, simply it is now much easier to simply select the straighten tool from the crop tool Options bar, equally described below.

Straightening images using the crop tool

To employ a precise image rotation, you can click to select the straighten tool from the crop tool options bar and drag across the prototype as shown below in Effigy 3.

Figure three When an image is opened upwardly in Photoshop, yous may detect that it is not perfectly aligned. If an image doesn't announced to exist perfectly aligned, click on the Straighten button in the ingather tool Options bar and drag along what should be a vertical or horizontal edge in the photograph. This will rotate the image so that it appears to be perfectly level.

Straighening a layer

Alternatively, if you wish to rotate an individual layer, make the layer active, select the ruler tool and drag to define the edge you lot wish to appear straight. Then click the Straighten Layer button in the ruler tool Options bar (see Figure iv) to straighten.
