As an example we will load 10 images from a folder, do some processing and output the images in two different sizes.
When you start the software it will automatically create a Read Node for you that lets you load images.
Double click on the Read Node to bring up the Properties Panel.
In the Properties Panel click on Load Image(s).
Navigate to the folder where your images are located, select as many as you want and click Open.
Now you will see a list of the images you loaded in the panel. To view the output of the Read Node, click on it in the Tree View and press V on your keyboard. A red outline around the node indicates that you are currently looking at this node.
By clicking on the images in the list you can toggle between them.
Now lets do something with our images.
Right click on the Tree View an select CropNode in the popup menu. This creates a new node in the view.
Too hook the Crop Node up to our read, left click on the output of the Read Node, hold the mouse button down and drag to the input of the Crop Node. This creates a new connection between the two nodes.
Double click on the Crop Node to bring up its properties and press V to view it.
In the properties pane select Center Square. This will crop the image to square dimensions, keeping it centered.
Now let’s create a ResizeNode, the same way we did before and hook it up to the output of the CropNode. This is what you should end up with.
Set the scaling in the Resize Node to 0.5 (i.e. 50%). This scales down the image by half.
Create another Resize Node and connect it to the Crop Node like so.
Set this Resize Node to 0.25 (i.e. 25%). Now we have two versions of our image. One is scaled down to half the original size, the other one to a quarter. Both have been cropped to be square.
Let’s save the images to disk!
Create a Write Node and hook it up to the first Resize Node.
In the settings panel of the Write Node click on Set Folder and choose a location. I have created a new folder called halfsize.
Under file name select Custom and enter a name. I have entered half_. Since we are processing several files we do not want them to all end up with the same name of course. Let’s add a number.
Click on the little Plus symbol to add another field to the file name. Set the dropdown box that appears to Number. We are setting it to 4 digits, starting at 1.
You can choose the file type below but we will leave it at JPG.
Activate the batch process check box at the bottom. This allows us to process all files contained in our Read Node at once.
Our Properties panel should look like this now.
If you click on Save Image(s) all ten images will be processed and saved to the specified folder.
Now create a second Write Node and connect it to the other Resize Node like this.
The settings will be the same, except that we change the filename and choose a different output folder.
Click on Save Image(s) and the ten images will be saved.
