You can resize, move and rotate path by using Free Transform control. See the example below:
Let's say you have this path that you want to transform.
Select Path Selection tool from Tool palette and click on the path to select it.
Right click the path and select Free Transform Path.
The Free Transform Box will appear around the path.
You can Resize the path by moving your mouse over the corner of the free transform box.
To change the width of the path, mouse over to the side of the free transform box.
To change the height of the path, mouse over to the upper or bottom side of the free transform box.
To rotate a path, move the mouse to further corner until the cursor turn into rotation cursor.
You can change the anchor point of the rotation. So that the rotate done in different axis. Move your mouse to the middle of the Free Transform box.
Drag the anchor point to different place, now try to rotate the path again, it will rotate around the new anchor location.
You can easily duplicate path by using Alt key,
First hold Alt key and mouse over to the path you want to transform.
With the Alt key still holding, drag the path to other place, it will drag as a new duplicated path. The original path still in the original location.
Paths actually do not exist in any layers, paths are stored in Paths Palette. Whenever you create paths, it is stored in paths palette, by default all paths are store in Work Path.
Work Path are temporally space for storing paths, you can your own work paths and rename it to more meaningful paths.
The icons at the bottom of the paths palette are:
Fill Paths,Stroke Paths,Load Path as selection, Make work path from selection, create new path and Delete current path.
To fill the path with color, just select one of the work paths from the Paths palette. Then press the Fill Paths button at the bottom of the Paths palette, it will fill the paths with your selected foreground color.
To stroke the path with color, just select one of the work paths from the Paths palette. Then press the Stroke paths button at the bottom of the Path palette, it will stroke the paths with your currently selected foreground color.
One of the good usage of paths is it can be convert into selection. Because paths can be store as work paths and paths can be easily manipulated and extend, paths has become a very good tool to work as a selection.
To load your paths as selection, select one of the work paths from the paths palette. Then press the Load path as selection at the bottom of the Paths palette, a selection will be created according to your paths. Note that your original paths are still remain intake in your Paths palette.
Make Work Path from selection
Sometime you might decide to convert your current selection to work path to gain the rich feature of work path editing for your selection. To convert selection into work path, make sure your current selection is still active, go to the Paths palette and press Make Work Path from selection.
If you want to create new paths that store independantly from all the previous paths you created, click on the Create new Path icon. It will create a new Work path in the Paths palette, all your new path will be store in this new work path. Note that you can rename the new work path like how you rename the layers. Just double click on the label of the work path to rename it.
Question: Help! I can't get rid of the paths from my canvas!
Answer:Because path automatically store as a work path in Paths Palette, you should delete your path from Paths Palette instead of Layer palette. See the section below.
If you want to delete work path from Paths palette, Select the work path that contains your unwanted paths from the Paths palette. Click the Delete current path icon to delete your paths.
Question: What if I just want to hide the paths from my canvas, and I will still need to use the path later?
Answer: The trick to hide your current paths is to create a new empty work path in Paths Palette and select this new empty work path as active work path.
After you draw a straight line and click on the , you can start a new path independant from the existing path. What if you want to continue extend the first straight path? You can use Direct selection tool.
You can select Direction selection tool on tool palette. But we will use short-cut here. With the Pen tool still selected, hold Ctrl and click on the path.
and click on the path to select it
Before we adding more path to existing path, we need to tell the path which side we want the path to be extend. To extend path to the right end of the path, with the Pen tool still selected, mouse over to the corner point(small white rectangle) until the cursor turn to the icon as shown below:
mouse over with pen tool
click on the corner point to select it.
When selected the corner point turn into black color, and the mouse cursor turn to a pen with a line, indicate that you may extend the path now.
now click anyway on the canvas to extend the path, but we want to extend a curve path instead. To delete this path, press Backspace.
after deleted the new path, reselect the corner point again.
this time click and do not release the mouse.
with the mouse still holding, drag the mouse to lower right as shown in the figure on the left.
to draw another curve path, release the mouse and click on the empty canvas area on the right.
same to the first curve, drag the mouse to the lower right.
We can move the direction point to adjust the curve path. To move the direction point, hold Alt key and move the direction point.
Figure on the left show the adjusted curve. Feel free to move other direction point to adjust both curve until you satisfy with the result.
If we try to extend more path from this point, it will always be curve path. To extend straight path from curve path, you need to remove the direction point. To remove the direction point:
Hold Alt key and click on the corner point. Note how the mouse cursor change when you hold Alt key and mouse over the corner point. It will remove the direction point to the right.
Note how the direction point on the right removed after click.
Now you can add straight line to the path. Click on empty area to add a path.
You may go back and adjust any corner point or direction point anytime. Hold Ctrl key and mouse drag the corner point or direction point to adjust the path.
To complete the path, click on Pen tool on tool palette.
Pen tool is good for selecting complext object, other selection tool force to made a full selection right after the first time your mouse release, this inevitably leave some unwanted regeon to clean up, while pen tool creates paths, which you can then convert into selections.
Pen tool offers control and precision, it is excel in selecting curve object when compare to other selection tools. However, this great tool require a greater learning curve.
The following figure show terms used in Photoshop Path.
We will be creating the Path shown on the left figure in this tutorial, start from the left straight line to the curves on the right.
First create a straight line path with Pen tool, select the Pen tool from the tool palette or press P key. We want to create a straight line that marked as 1 as shown in figure on the left. Start from the left of where you want the line begin, click once and then move your mouse to the right end of the straight line and click once as well.
If you want to draw a exact horizontal, vertical or 45 degree angle line, hold Shift key as you click. To complete the path, click on the Pen tool button again.
