Looking for a quick and easy way to manipulate images without having to master a battery of functionalities or any hassle of sort? With a decent collection of essential tools, editing and annotating images with preview on macOS 10.14 is a no-brainer operation. The moderate battery of tools on the app is available on a user interface with a minimalist design, making it all the easier to edit images and mark up pdfs with Preview on macOS 10.14. By learning how to manipulate images using Preview, you can easily alter images without using complex photo editing software like Photoshop or Pixelmator. Read on to learn more.
Preview is Mac’s default image viewer, so when you double-click an image on your Mac OS Mojave, it opens automatically in Preview. And if your default image file association settings has been changed, you can view images with Preview by Command-clicking or right-clicking an image file, and then scrolling to 'Open with' and then choosing Preview.
To open a file directly from the window of Preview app itself, select the Preview app from the Application folder or Launchpad. Tap 'File' on the menu bar of the open Preview window, and then select “New” and choose the desired image file.
Preview comes with an impressive collection of tools to edit images and mark up pdfs with preview on macos 10.14, including tools for adding text, drawing lines, inserting arrows and custom shapes, etc. All the tools are applicable to both PDF files and images. To access these features, tap the 'Show Markup Toolbar' around the top-right corner of the screen. Alternatively, you can tap 'Tools' on the menu bar, scroll to 'Annotate' and select any of the annotation tools.
You can insert portions or the entirety of images on an image to form new backgrounds or manipulate the image in various ways using Preview. To do this, open both images on the same Preview window by selecting and opening both of them. Then select the image whose portion you want to insert in the other image, and then use the 'Instant Alpha' tool to crop out the unneeded parts. Press 'Command' + 'A' to highlight the cropped image, and then press 'Command'+ 'C' to copy it. Switch over to the image you want to insert the cropped image into, and then press 'Command' + 'V' to insert the copied image. You can also rotate and resize your pasted clip (see the sections below) to make it fit in more perfectly.
As earlier noted, the functions for editing images with OS 10.14 preview are easily accessible. To rotate an image, simply click the 'Rotate' button on the toolbar around the top-right corner of the window as many times to perform any rotation sequence. Open the 'File' menu, and then select 'Save' to save the changes.
The rectangular selection is the default cropping setting of Preview. Simply mark out a rectangular section to be cropped, and then tap 'Tools', and then select 'Crop' .
Nonetheless, with an additional cropping function, it’s even easier to edit images with OS 10.14 Preview. You can remove the background or portions of an image by using the Instant Alpha tool. Select the 'Instant Alpha' tool from the 'Tool' menu, and then drag your mouse around to mark out the area to be removed with a red shade. Select delete to remove the selected area. Save the changes by opening the 'File' menu and then selecting 'Save'.
Open the 'Tools' menu, and then select 'Adjust Size'. A 'Resize' dialog box will then pop up to allow you to adjust the size of images based on numerous measurement units, including pixels.
Note that the quality of the image actually diminishes the more you enlarge the image, although the aspect ratio will remain intact by default. Save the changes by opening the 'File' menu and then selecting 'Save'.
With a color-adjustment functionality that’s accessible through a couple of clicks, it’s relatively easier to edit images with apple’s preview on macOS 10.14. Simply open the 'Tools' menu, and then select 'Adjust Color' to access the color-adjustment tools. These include tools for adjusting contrast, temperature, exposure, sharpness, etc. They come in sliders that allow you to automatically view the changes as you’re apply them.
Preview allows you to browse through the history of file changes and edits. To view the previous changes you made on a file, open the image, and then open the 'File' menu, and then select 'Revert To', and then select 'Browse all Versions', This will bring up all the saved versions of the image file.
Taking screenshots on MacOS Mojave is only a matter of a couple of clicks. To take a screenshot of the entire screen, press 'Command' + 'Shift' + '3'; To take a screenshot of a selected area, use '4' in place of '3' in the keypress sequence. Using '5' in the keypress sequence opens up a comprehensive snapshot menu with functions for capturing the entire screen, a particular window, a selectable area on the screen, and a video of the entirety or a selectable area of the screen. This menu also features options for saving, copying, and mailing the screenshot, as well as for editing the image with the OS 10.14 preview.
For a good number of reasons, you may run into a need for an alternative to Preview for editing images.
