The Move tool
Auto Select Layer
When this option is selected, you can drag an image without first selecting its layer. If the option is not selected, the layer that includes the selection must be selected first in the Layers palette. Holding down the [Ctrl] key while clicking an image will automatically select its layer when the Auto Select Layer option is turned off.
Show Transform Controls
When this is selected, a bounding box containing eight adjustable points appears around the image. The points can be dragged to transform the image. This is similar to using the [Edit] – [Free Transform] command [Ctrl]‐[T].
Layer Alignment
The layer alignment option automatically lines up layers. The option is used when there are two or more linked layers within the image.
Tips:
Holding the [Alt] key while dragging creates a copy of the selection.
Dragging the selection to another image window makes a copy in the new window.
When the Auto Select Layer option is selected, you can drag without selecting the layer first.
If the Auto Select Layer option is not selected, you must first click the layer before using the Move tool.
The Crop Tool
The Crop tool
Use the Crop tool to select an area to crop. The Crop border will contain eight adjustment points that you can use to move, or rotate the crop area. To complete the crop, press [Enter]. Pressing [Esc] will undo the crop selection.
The Crop Tool Options Bar before a Crop Selection is made:
Width and Height
Set the width and height of the crop area.
Resolution
Set the crop resolution.
Front Image
Click to automatically set the size and resolution to that of the front image.
Clear
Clears the entered values.
The Crop Tool Options Bar before a Crop Selection is made:
Cropped Area
Selecting [Delete] removes areas outside of the crop area completely. Choosing [Hide] hides the unwanted areas from view. Hidden areas can be recovered by pressing [Image] – [Reveal All].
Shield Color
Indicates which areas are outside of the crop area.
Perspective
Check this option to use the adjustment points to give the image perspective.
Tips:
You can also use the Selection tool to create a selection, then select [Image] – [Crop].
Changing the Image Size
Each image appears on an image canvas. You can use [Image] – [Image Size] to change the size of the image and canvas at the same time. This command can also be used to change the resolution of the image.
The Image Size Dialog Box
Pixel Dimensions
Displays the width and height of the current image.
Document Size
Displays the print size and resolution.
Scale Styles
When checked, style effects are scaled along with the image.
Constrain Proportions
When this option is checked, the ratio of the width to the height is kept constant as you resize the image.
Resample Image
If you select the Resample Image option, the dimensions of the image will remain the same regardless of changes made to the resolution. In other words, Photoshop will add or remove pixels so that your image is the same size regardless of its resolution. Without this option selected, the total number of pixels will remain constant, and changes made to the Resolution value will increase or decrease the width and height measurements of your image accordingly. Note that selecting this option and altering your image’s resolution will affect the file size of your image.
Changing the Canvas Size
The size of the canvas can be changed without affecting the size of the image by using the [Image] – [Canvas Size] command. If you reduce the size of the canvas, you will be warned that the image will be cropped. If you increase the canvas size, the additional area will be filled with the background color.
The Canvas Size Dialog Box
Current Size
Displays the file size, width, and height values for the current image.
New Size
Used to set the new size of the canvas.
Anchor
The white square represents the position of the image on the canvas. Click on one of the squares in the grid to anchor the image at that position. This will change how space is added or removed when you change the canvas size. In this case, additional space will be added equally to all sides of the image.
