In order to start working on a new document, first click ‘File’ menu and select ‘New’. Then, select ‘Document’ which is displayed in the fly-out menu. You will see a box from where you can change the settings of the page as per your requirement. After changing the page size or layout, you have to click ‘OK’.
After that, you have to click ‘File’ menu and then ‘Place’ in order to open the Place dialog box.
Find the image file which you want to import into the layout. After finding the file, select it and open it by clicking ‘Open’. It will load the mouse cursor along with the thumbnail of the image on your screen.
Then, insert the image into the page by clicking at the location at which you want to place your image.
Select the ‘Selection’ tool from the Tool panel.
There will be 8 handles which you can use to crop your image. You can crop your image in any dimension by using the handles on your screen through your mouse button.
