By Color Select Enables you to pick areas of an image that have a similar spectrum of colours. This
Tool tool and the Fuzzy Select tool are different in that the latter only selects continuous
pixels, or those that are close to one another. On the other hand, the By Color Select
tool selects every pixel that falls within the colour range, regardless of where it is on
the image.
Intelligent When attempting to select an area with prominent colour changes at the boundaries,
Scissors this tool can be helpful. To utilise the Intelligent Scissors, click the edges of the zone
you want to pick in order to generate a collection of “control nodes,” also known as
anchors or control points. Following any high-contrast edges it can locate, the tool
creates a continuous curve that passes through these control nodes.
Note that a good, smooth path is not always produced by this tool. Instead, the Path
tool is more frequently used by knowledgeable GIMP users.
To use selection tools on images, follow the steps given below:
Step 1: Open the image on which you want to apply selection tool.
Step 2: In the GIMP toolbox, click on the selection tool icon. The selection tool can also be chosen by clicking the
desired Selection tools after choosing Tools from the program’s menu. To pick the desired area, the tool of
choice is dragged over the visible portion of the image.
Step 3: After the region has been chosen, a boundary (such as a rectangle, ellipse, marquee, etc.) is visible all the way
around it.
Step 4: The chosen area is used for additional image processing and other processes.
