To make the Ruler display other units of measure, you need the option On a measurement scale. If you change the unit of measurement on the scale of the rulers to, say, centimeters, then automatically on the Rulers options panel all the corresponding values will also be displayed in centimeters. If line 2 (L2) was created, this field indicates the angle between L1 and L2.ĭefault Ruler repeats those units of measurement that are specified. Photoshop measured this for us - 16.9 degrees. The angle is very small and in geometry is called acute. You can see it visually in the screenshot above. That's exactly its length and will be displayed in this field.Īt is a display of the angle of the line with respect to the x-axis.Īgain, draw a horizontal guide through the line's start point and get a measurement of the angle between the line and the guide. The mouse cursor will change, which means you can draw another line from the selected point. To do this, when the document already has one segment, hold down the Alt key and move the mouse pointer to the start / end points of the segment. True, it can be constructed as a continuation of one of the points of the segment. L2(line 2) is the length of another line that can be added to the document. In the example above, if the projection of the line width was 398 pixels, then the length of the line itself is almost 416 pixels. In this case, this is not a projection, but simply a measurement of the line itself, taking into account the angle of inclination. L1(line 1) - shows the actual length of the drawn line. If it were a perfect horizontal line, then the height value would be 0, because the projection of the start and end points are both at the 0 value on the Y axis. This means that, regardless of the angle of the segment, it has a specific value for the width and height of the image that it includes. This is nothing more than the projection of this segment onto the X coordinate axis - width (W), and onto the Y axis - height (H). W and H - width and height- calculate the distance that the line has traveled along the X and Y axes. Look, I'll draw the guides, and you just count what the rulers show and compare what is displayed in X and Y: The values that these options show are taken from the rulers near the document. Where X is the horizontal coordinate axis and Y is the vertical one. X and Y are the coordinates of the starting point of the segment. Now look at and its readings for this measurement: (it’s hard to see on the screenshot, I tried as best I could to focus on where the segment of the ruler was) Suppose there is a certain image and the task is to find out what is the distance between two red dots: Now let's move on, directly, to the removal of measurement readings. Parameters panel or what the Ruler measures Photoshop will do everything itself and show a perfectly even ruler. It's simple, hold down the key and draw a line segment. Only the position of the second point will remain unchanged. In this case, you seem to be re-creating the dimension. If you drag one of the two points of the segment, you can completely change it. At the same time, the segment will retain its dimensions and angle of inclination. To do this, with the Ruler tool selected, move the mouse cursor over the segment, when it changes, simply drag it to a new location. More on this below in the text, but for now here is a series of actions that can be applied to the ruler: Next, all attention should be switched to the tool options panel, because there will be many numbers with measurements that have calculated this segment in all planes and in all possible ways. Then, without releasing the pressed mouse button, drag the mouse to the point where the end of the segment for measurement will be. With the tool selected, click on the image where the distance calculation will start from. The ruler is located in the group of measurement tools (where it is headed): I emphasize that this is not a graphic element, which means that it will not be visible when saving the image. The ruler is an auxiliary element and is a segment limited by two points. Ruler tool(Ruler) allows you to measure the distance between two points in a document.
