In the flood fill can be done separately from the selection mask falloff function or can use the same falloff function where contiguity is defined at any tolerance. (There's pseudocode for the flood fill algorithm in that link.) The tolerance for contiguity The actual curves don't have to be linear either, you can use any fall-off curve such as a cubic, or cosine.įor contiguous selection, use the above technique combined with a a flood fill algorithm. Photoshop represents this withĪ tolerance of 30 and a "fuzziness" of 10 (the range 20-40 is centered on 30 and has a radius of 10). Pixels are assigned a fractional mask value, and finally differences outside the fall-off range will not match (i.e.: match at 0%.) The match values are used to construct a selection mask.įor example, you might say that pixels that are 20 units of distance or less apart match 100%, and pixels that are 40 units of distance or more match at 0%, and values in between are linearly scaled between 100% and 0%. A range of differences will match at 100%, then there will be a fall-off curve where less matching Such a difference function might be: sqrt( (R2-R1)^2 + (G2-G1)^2 + (B2-B1)^2 )įor non-contiguous selection, assign each pixel a mask value based on the difference relationship between each pixel and the magic/selected pixel. Regardless, you'll get a scalar quantity representing the difference between the pixels. To use the magic wand tool in Paint.NET: Go to Tools > Magic Wand, or select the Magic Wand icon in the toolbar. HSV colourspace or some other colourspace before computing the distance. Other techniques involve converting both pixels to or One typical way is to find the "distance" between the points in Hopefully assigning a linear value to the difference between them. This makes it easy to make a selection that includes all red objects as well as all green objects (assuming they are in that range).You need to be able to compare pixels to see how well they match. Keep in mind, however, that doing so will bring in not only that object to the group, but also all similar objects that fall within the set tolerance. You can add more objects to the selection by Shift-selecting another object. Adding Objects to a Selection With the Magic Wand Tool Turning it off lets you limit your selection to items on the same layer.

This option will automatically select all matching objects, regardless of which layer they’re on. By default, “Use All Layers” is turned on in the Magic Wand options. All of the objects that match your criteria will automatically be selected. 5.6 Step 5: Refine the edges of the selected areas. 5.5 Method 1: work by selecting the background. 5.3 Step 3: Configure the Magic Wand Tool in Photoshop. Simply choose the Magic Wand and click on an object. 5.1 Step 1: Open your product photo and duplicate the background layer. Once you’ve set up your criteria and tolerance levels, selecting the matching objects is a breeze. The star with 61% opacity falls outside that range and is therefore not included. With a tolerance value of 10%, selecting the star with 50% opacity with the Magic Wand will also select the oval with 56% opacity. The magic wand tool to change color is a cake in the image editor name Adobe Photoshop. If you don’t see all of these options, you might need to toggle them on by using the panel’s menu in the top right corner. Select as many of the attributes as you want to match by clicking each checkbox. Your options include: Fill Color, Stroke Color, Stroke Weight, Opacity, and Blending Mode. In the Magic Wand panel, you indicate which similar attributes you want the Magic Wand to select for. To set the options for using the tool, either double-click it in the panel or choose Magic Wand from the Window menu. You can find Illustrator’s Magic Wand tool in the Tools panel, just below the Selection tool. If you’re one of those people, the Magic Wand tool might be your new best friend! Magic Wand Tool Basics As a result, I’ll have objects that are all red, but not the same red, meaning the Select > Same option won’t catch them. It’s a great option for me because I have a bad habit of accidentally assigning two very similar colors to objects. With “magic” in the name, I don’t know why I often forget about it. On the Options bar, set the tools options: Tolerance defines the tools sensitivity. One technique I use-once I remind myself that it exists-is employing the Magic Wand tool. Magic Wand Tool In the Toolbox, select the Magic Wand Tool. Whether you’re a “drag across all objects” kind of guy, or a “shift-click to select each item” sort of gal, the point is that many roads will lead you to your destination. It will select any contiguous areas of a similar color. When it comes to selecting objects in Illustrator, you have several different ways to approach this task. This tool, represented by a magic wand, allows you to make Selections by selecting a point of color.
