Load 2 separate images into filter?

I'm a newbie who has spent about three hours in help files, forum searches and experimenting, trying to create my first filter using the latest version Filter Forge. The filter I am trying to create needs subtract one image from another, and then display the result.

So far no matter what I try I cannot load two separate images into the filter. I've read the Multiple Image info in the Help file. I've searched the Forums. There must be something this Newbie is missing?

Anyone have an example filter they've created that subtracts one image from another? Maybe by looking at how you did it I can figure out how to create the filter I need?

And this way this ONLY allows to have colors input, BUT if you change the "External Images" from "Not Allowed" To "Allowed" it will LET you upload your own images apart from the one you have already loaded using the "Image" component

You can see a good example on how the color control is used to load additional images by opening and editing inside the FF Filter Editor this very good filter made by Morgantao that uses many of them.

To be able to solve this errors is very easy, you only need to add to the "color control" component as "Default source" the "Image" component that is going to be overriden, AND load any kind of image that you want so there is one source and is not empty.

Here below is how should look after adding the Image component and loading the image

Glad of being of help

Here is another part of the tutorial that I forgot to put

The default and "normal" color control image load assumes and suposses that you are going to load "square" images and so there will be no problem, and does not need to do anything else.

BUT if the loaded images are NOT square, you could perhaps and probably have problems in the following components added to this control, OR also you want to customize the placement of the image.

So there is a further "Image placement" option

When loading a NON square sized image, you will see some transparent background checkerboard showing you that the image does not fit the pre-defined square, so then you have many options to customize how you want to place the image using the 4 drop-down menus below.

The checkerboard will appear wherever the image does not fit the default square (up, down, left, right, round...)

You do not need to fill the whole square to be able to use the image inside filter forge, because you can perfectly use non-square images if the filters and components accepts them.

As far as I know, there is no limit of how many "color controls" components you can use to load as many images as you want BUT the problem comes when connecting this images to the components that they have limitations and can only use fr om 1 to 7 sources, depending on which component you want to use and connect with.

The image placement ALSO is useful When using a window wh ere the canvas needs to be bigger than the image loaded. The best example I can think for this second option is the Bombs Away filters fr om CFandM ----> Bombs Away FF 2.0 and FF 3 .0 and Bombs Away Multimage for FF 3.0
