Call the Free Transform and Transform commands in the Edit menu to apply transformations to the selected layer or object. The transformation parameters are displayed on the Settings Panel.
Note: If you want to transform the entire image, you should select the needed operation in the menu Image -> Transform Image. In this case, all layers of the active image will be transformed.
To transform the contour of the selection, use the Transform Selection command in the Select menu.
Move. You can change the position of an object horizontally (X) and vertically (Y). The parameter uses the coordinates (in pixels) of the upper left point of the bounding box or of the center point (if the sign is activated). Usually the center point is fixed, but you can move it to the different location.
Place the cursor inside the bounding frame and drag the object. If you bring the cursor to the center point, you will get a pointer with a circle - now you can move only the center point.
Scale. You can adjust the size of an object in width (W) and height (H) (in percent). Drag one of the eight square markers on the frame to increase or reduce the size. The cursor will turn into a two-sided arrow . Use Shift-key or press the sign between W and H to constrain the proportions of the object. If the sign is deactivated the proportions can change. Hold down the Alt key scale a fragment or a layer in relation to its center point.
Skew. You can shift some parts of an object relative to the others. When you bring the cursor to the frame, it will look like this . Press and drag to transform the object. Hold down the Alt key scale a fragment or a layer in relation to its center point.
Rotate. You can rotate an object. The center of rotation can be changed by moving the center point of the object. Outside the bounding frame the cursor turns to a rounded two-sided arrow . Holding down the left mouse button, rotate the object clockwise or counter-clockwise. If you press Alt, the rotation angle will change in five degrees.
Click on the Reset Center Point button to restore the center point in its default position.
Press OK to apply changes. To cancel the transformation press Cancel or use the Esc-key.
Also, you can apply transformations using the following commands from the Transform submenu:
The commands Rotate 90o CW, Rotate 90o CCW, and Rotate 180o rotate the image to specify degrees .
The Flip Horizontal command flips the image along the vertical axis.
The Flip Vertical command flips the image along the horizontal axis.
