Choose between the rewards showing up as an overlay on top of Warframe, having a new window spawn displaying the items on a second screen, or light mode, having no display show up but copy to clipboard.

Change how long the overlay stays displayed. Change to high contrast mode to improve readability and change whether or not items get highlighted.
If display mode is set to Overlay, you can adjust where the result overlay appears.

Choose the minimum and maximum allowed size for the snap-it results overlay. Change how long the snap-it results stay displayed for.
Change if you want snap-it to attempt to detect how many of each item you have, and let WFInfo remember that.
Choose if snap-it is allowed to use more of your CPU at once for faster results.

Choose your preferred hotkey to activate WFInfo's reward detection. We recommend printscreen by default but you can use almost any keyboard key and even some mouse buttons!
Avoid setting your activation key you'd frequently press for other reasons.

Snap-it efficiency, these are ducats per plat values. Anything under the min value will display as red and anything above the max value will display as green.

Useful in cases where you have issues with theme detection or the standard theme presets.
Use dropdown menu to override the automatic theme detection. In most cases, this should be left on AUTO
Use the cog (settings icon) to modify the CUSTOM theme option, if the standard options are insufficent

Auto will use the logs created by Warframe to detect when the reward screen is being displayed and run the program for you!
Clipboard will copy the results into your clipboard allowing you to paste it into the chat for other players (Ctrl + V)
Auto List will only work with Auto enabled, it wil spawn a listing screen whenever it detected rewards and an end of mission
Auto CSV will only work with Auto enabled, it will record information about your reward choice in %appdata%/WFInfo/rewardExport.csv
Auto Add will only work with Auto enabled, whenever it detected rewards and an end of mission, it will open an interface for increasing how many of the chosen reward you own according to WFInfo. See Count Item feature found under Snap-it options
If you ever run into a problem running WFinfo then you might be asked by the developers for a "Debug zip", this contains information useful to the developers for debugging what went wrong. This button will generate a series of zip files that can be sent over discord (All are under 8mb)

To configure a theme properly, we need an image to test it on.
If you have recently tried using the reward screen scanning or snap-it feature, click Load Last Use to use it for testing.
If you want to use some other image instead, click Load From File and select which image you want to use.

After using one of these buttons, the image will display on the left

There are 4 filters in total, two that use RGB for describing colours and two that use HSL.
To start off with, select one of these filters and click the checkbox to enable it. Which one you select isn't important
RGB and HSL describe colours in different ways, which could affect how good of a filter you can make. If you can't get a good enough result with one, you should try using the other

Show Unfiltered> can be pressed at any time to show your original test image
Apply Filter can be pressed to apply the active filters. A pixel will be black if it was within the assigned range for all parameters for at least one of the enabled filters, otherwise it will be white

Here, I picked Primary HSL Filter and have resized the window to better see what the filter will be doing. The image in this example is using the Vitruvian theme with Tritanopia colorblind compensation

I am now going to do the following:
1. Adjust one of the sliders, in this example I will be changing Primary Hue Max to about half. You can also write a number in the corresponding textbox, using . for decimals
2. Click Apply Filter

As we can see, the text is still black in this image, but so is a lot of other things. For you, the entire image may be black!

We will now repeat this process, trying to find when the text switches from black to white

After adjusting and applying the filter a few times, this time the text turned white!
I know I'm close to the correct value for what I'm adjusting right now, so I'll adjust it just a bit more and it should be perfect!

There we go! Time to repeat the process for each of the other sliders. Don't forget that the min value should always be lower than its corresponding max value

You may notice the text for Pyrana Prime Barrel in the bottom-right corner is still white. We'll cover that later

After adjusting all the other values, and this filter turned out very well.

However, the Pyrana Prime Barrel in the bottom-right corner isn't visible. Why is that?
In the original image, I was hovering over the Pyrana Prime Barrel. The game uses a different color for this, so we'll need to use a second filter.
To do this, simply enable another one of the filter options and repeat the adjustment steps, this time focusing on just the text for the hovered item.

Now this filter is complete, and ready for use!
This example turned out really well. Even if you get a lot more noise than this, it can still be enough for WFInfo to work well.

Once you're done adjusting your custom filter, simply select CUSTOM in the Theme section of the settings menu

To share your newly customized filter with someone, click Export Filter.
The exported filter will appear in the text box above the buttons.

To import a filter, clear the textbox above the buttons, paste the filter into the text box above the button and click Import Filter
Importing a filter will delete your old filter
