Basic Operations

Basic Operations: Resize, Crop, Rotate

> You can access the Resize form from the main menu by either Edit>Resize Project or Edit>Resize Canvas

> Resizing for the screen

> If you only need to display the resized picture on a screen, or as part of a web page, then you may want to modify the "New Width" and "New Height" values directly. The values are expressed as pixels units.

> Resize for printing

> If you need to change the size for printing, you have two options:

> - you may change the picture's resolution (that is the pixels density per inch). Greater resolution will produce smaller pictures and viceversa when printing. This method leaves to the printer the task to refit the picture to a different size. When you save the picture to a file, the information about the new resolution is also saved.

> - you may change directly the size that the picture should have on the paper expressed in real world units such as cm, inch or mm. By this method the program will resize the picture, knowing the new size on paper and the resolution.

> You can of course use both options at the same time.

> Note that if you need to increase the picture size for printing it's always advisable to change the size directly rather than decreasing the resolution.

> Resize a Project:

> Resampling means changing the size of an image, by stretching pixel information on a smaller or a bigger area. When you down-sample (decrease the number of pixels), excess information is deleted from the image. When you up-sample (increase the number of pixels), new pixels are added, thus adding information that did not exist. You have to specify an interpolation method to determine how pixels are added or deleted.

> There are different resample methods: A good one is the Lanczos (bicubic) that can be used for down-sampling as well as up-sampling (reducing and increasing size).

> If you are not sure which method to use, you can check the "suggest best method" option.

> Resize Canvas

> Resizing the canvas will just affect the background layer.

> You can choose in which direction the canvas will be extended or cut by selecting one of the 5 direction buttons.

> Center button means that canvas will be extended or cut in all directions (top, bottom, left, right)

> Other buttons are provided to change canvas at Top-Left, Top-Right, Bottom-Left, Bottom-Right corners, or in one direction only.

> Crop:

> In Focus Photoeditor you can crop pictures by selecting a rectangular region with the Work/Crop area tool and by selecting the command Edit>Crop to Work Area from the main menu.

> If you have layers, the current layer will be cropped and not the background. If you want to crop the background, first select it from the layers window before.

> Rotate:

> The most often used rotations are 90 degrees right or 90 degrees left; that's why they are easily accessible from the main menu>Process>Rotate 90° and from the top toolbar.

> If you have layers, the currently selected layer will be rotated.

> For rotations of custom angle take a look at the transform menu.
