You’ve uploaded an image to the document library. It’s almost perfect, but it’s missing a little something. It could use a little more focus to really highlight the message you’re trying to communicate. Just a little editing and the image would draw your readers in. You could edit the image in your favorite image editing program and re-upload it, but that’s a bit tedious for the minor changes this image requires.
What else can you do?
Lucky for you, Liferay Portal now comes with its own built-in image editor.
A crop here and there, a little bit more contrast, and some adjustments in saturation, and boom! The image is ready to go.
Since Liferay Portal CE 7.0 GA2 and Liferay DXP 7.0, users can edit images within portal instances. To access the image editor, go to the Documents and Media repository and locate the image you want to edit. Click the Actions icon () and select Edit With Image Editor.
The image editor can also be accessed through the item selector. Essentially, anywhere you have an image, you can edit images. For example, in blog entries, web content articles, and wikis, you can view a preview of the image.
Within the item selector preview window, you can access the image editor by clicking the pencil icon () in the bottom right corner of the preview window.
The image editor was designed with quick editing in mind, and offers a minimal, user-friendly UI:
The main toolbar consists of three buttons, each of which contain a subset of options. The menu options are described below:
Transform Tools ()
Crop: Lets you reframe the image, by removing the outer portions.
Resize: Lets you resize the image in pixels. If the lock is closed, the aspect ratio remains locked, and changing either width or height will automatically adjust the other dimension to maintain the aspect ratio. When the lock is opened, the width and height can be changed individually, allowing the aspect ratio to be altered. This is not recommended though, as the image can become distorted.
Rotate: Lets you rotate the image to the left or right, in 90 degree increments.
Adjustment Tools ()
Saturation: Lets you adjust the amount of color saturation in the image. The default value of 50 is the current saturation. The slider values range from 0(completely desaturated) to 100(completely saturated).
Contrast: Lets you adjust the difference between highlights and shadows. A value of 50 is the current level of contrast. The slider values range from 0(no contrast) to 100(full contrast).
Brightness: Lets you adjust the amount of light in the image. A value of 50 is the current brightness. The slider ranges from 0(completely black) to 100(completely white).
The third and final toolset is a preset of filters, which you can access by clicking the wand icon ():
Once you have made changes to the image in the editor, you can click the Cancel button to cancel the changes, or the Apply button to apply the changes to the image. Once you have applied changes to your image, the history bar appears:
The history bar allows you to undo, redo, and reset changes that have been made to the image in the editor. Note that the reset button should be used with caution; once it has been pressed the image is reset to its original state, causing all changes made within the editor to be lost.
As mentioned earlier, you can access the image editor in the Documents and Media repository, or through the item selector in blogs, web content articles, and wikis. When the image is edited within the Documents and Media repository, and saved, the version is incremented a minor version i.e. version 1.0 to version 1.1. You can view the previous versions of the image through the version history table, under the information section for the image. When the image is edited within the item selector, and saved, a copy is created of the image and saved to the document library.
