The Rectangle Select Tool

Updated on: November 19, 2014

Hello and welcome to this video series on the Gimp. Now, on this particular video, we're going to be touching base on a couple of the select tools here in our toolbox. And in this particular video, we're going to be working mainly with the rectangular select tool but we're kind of touch on these other ones because there are some similarities between these. So once we cover the one, then you'll have a pretty good idea on working with the others as well.

So let's go ahead and chop right into this and get us a new palette con and we're going to go with the 250 by 250 pixels. So basically, it’s a square so determine whether we want to use portrait or landscape will make no difference or whatsoever. And as far as the additional info here, you can alter this by going to advanced options. Just click on the little plus sign there. If working with webpages or websites, the 72 DPI or the resolution of 72 points really is plummy. You go larger than this and it's going to affect the file size which of course will affect the amount of time it takes for your webpage to open, to upload, or download this particular images or creations. You're going to be using the dpi that’s given here. The only time you really want to go more than 72 is if you're working with printing. If you're going to be printing a particular object or a picture, then you may want to go like 300 DPI. That's just an idea.


The color space --- the space if you're working with color, RGB, or grayscale which basically is black and white.

The background color --- you know I just see this a lome unless of course you're working with photos then you might want to go with transparency. You know, just an idea there. Then again, play around with it.

The comment section --- if you're better than eagle maniac then you might want to toss your name here otherwise because this will not show too often anyway but it's there in case you want to play around with that.


So let's go ahead and get us our new palette of 250 by 250 and we'll move it over in between the two docks here. And as far as the select tools which are basically these top six in this top row here. Just kind of touch on this, this is a rectangle select tool, our ellipse select tool, the free select tool. The free select tool will determine a particular part of your canvass although with this one being only a rectangle in size or shape. This one being in the ellipse in shape and the free select tool as you may have guessed by the name you can do whatever you want but you'll see down here in our additional functions of these tools that we select, there's going to be some similarities namely this tab section here. So under the ellipse tool you'll see that it all says the antialiasing, feather edge, expand from center, and the different modes. The fuzzy select you can see the name right here the tools we select, the select by color, the scissors, and the foreground select.


Now this one here, it’s kind of a free hand or the paths tools based for free-hand drawing kind of thing. We’ll get into that on a later video. But these other select tools you see again they have their similarities and some of the functions that are offered. So again by going over the one rectangle select tool you'll be able to adapt the same information for the most part for these other select tools as well. But we'll go on those in just a later video but for the time being, under the rectangle select tool we've got a rectangle and you're going to just re-size it here by highlighting  one of these segments and move it in or out to your desired area that you need selected.

Now, with the select tool any work that will take place will only take place inside of these moving or marching ants. As you can see, they are moving right along here and only just in the straight this by opening up our brush selection tool and as you can see nothing has happened on outside of this selected area, only inside. So again that’s one of the purposes behind using one of these select tools up here. I’m going to erase this and undo it by holding down my control key on my keyboard and hit in the letter Z. I’m going to go ahead and get rid of this by doing the same task again. So now, we're starting again with our empty palette.


I want to show you the feather edges and based on what it's going to do is just kind of feather or blur the edges of our selection. So the default is ten and of course you're going to adjust this. The higher the number move to toggle up, the fatter the blur will be. So let's take it down here again just for demonstration purposes and in this case 12.6. Now this will only work if you select this or tick this box prior to creating your selected box, or in this case, rectangle. So if you select this and then click on this, it's not going to work. So let's go ahead and demonstrate our feathered edge here.  You can see again it's just a little bit of a blur around the edges and to demonstrate this more, select and kill our marching ants. So you see the little blurring around the sides here, okay and by the way with it being unselected I can manipulate the information in here anywhere I want, anywhere inside of our palette. So again, that's one of the reasons behind using the select tools. So control Z my mess here.

And rounded corners, just the name may imply, you're rounding the corners. Unlike the feathered edges, you can make this adjustment after you've made your selection. So almost up to an ellipse or in this case, a circle. So again that's our rounded corners. This works pretty cool. I’ve used this whenever I’ve been making badges or I wanted to e-ink the header image, or a webpage, or you've got or want rounded corners. It comes in pretty cool or works pretty good there.


So let's pretty much our select tool is far as this three here, the rectangle, the ellipse, the free. These are all basically the same or more than a thing to down here in the corner. I’ll go over the mode quick to highlight our mask. So here, in this particular mode we can add to the current selection. Now to kind of see what I’m working with here, go down here to this toggle quick mask right here in the left corner and you're going to see it has already added the feathering there. The feathered edges or the blurred edges so you can untick this if you don't want that in there. So again this just gives you a better view of what you have selected. Now, we can untick this and this two here we will subtract just as we added, we can subtract. So again that's a bit of our modes up here. We’ve touch based on the feathering of the edges and rounding of the corners. And a lot of this other information down here you can just play around with this. These are the main functions of our select tools, the rectangle, the ellipse, and the free hand.

So I hope you learned something from this video on utilizing the select tools in your Gimp. Thank you very much for watching. Have a great day!
