Bill Rosener: Hello, Dr. Bill, welcome back in this video. We're going to take a navigation button, maybe one a pink one pointed to the right. And we're gonna change it to a blue arrow pointing up. And this is kind of a common operation where you maybe have got some navigation buttons. And you want some, maybe point in in various directions there.
Bill Rosener: Okay, so fair. First, st if you want to do, is press on the assignment. 17 subdirectory, you go ahead and click on. Write gift and save that
Bill Rosener: I've already got mine open in adobe Photoshop, and maybe in this case that very 1st step. But it's kind of a small image, but 1st up I might want to do is just go ahead and zoom in here a little bit.
Bill Rosener: and there we go.
Bill Rosener: And as soon as I look at this I can see that this is an index format. It's a get format and index. A lot of operations are not available, I cannot create layers. So the 1st step I'm going to do is come up here to image mode and change this to RGB color.
Bill Rosener: Now I can actually work with layers.
Bill Rosener: So if I want to get this haven't maybe changed the color and also change the direction. So it's now a blue arrow pointed up. One thing you might be inclined to do. So let me just come right over here.
Bill Rosener: I'm gonna go to image rotation, and I'm gonna go counterclockwise.
Bill Rosener: But what you're going to find is not at all did it shift.
Bill Rosener: rotate the arrow? But it also shifted the background as well. Kind of that border around the outside. And let's assume we want to leave that border alone.
Bill Rosener: So at this point, what I'm gonna do is go ahead. And now use the rectangle marquee. I'm just gonna highlight an area around this
Bill Rosener: and that's gonna copy it.
Bill Rosener: edit copy and then turn around and edit paste.
Bill Rosener: And now I've got that on its own layer.
Bill Rosener: So now what I'm doing is, turn this eye off. Now come back here to the background, and I'm actually go ahead and remove it from the background. So I just highlight an area around the Arrow. I'll go ahead and I use my magic wand.
Bill Rosener: Come right over here and press
Bill Rosener: sample that color, and then I'll come right up here and hit Edit
Bill Rosener: and Phil.
Bill Rosener: and okay.
Bill Rosener: and I'll go ahead and deselect that.
Bill Rosener: So now what I've got
Bill Rosener: is the arrow on its own, the arrow on its own layer. And then I've got this as well.
Bill Rosener: and if you wanted to, you could come on, go ahead and actually clean this up a little bit. I could use the magic wand. I could highlight oops. Make sure your active layer highlight kind of this gray, and just press that delete on the keyboard to remove that.
Bill Rosener: So now I've got the background, and I've got the Arrow.
Bill Rosener: So now, but maybe at this point I'll tell you. I'll go ahead and put this back on.
Bill Rosener: and then I can come right up here. You can see I've got the arrow as my active layer. I come right up here to
Bill Rosener: edits and come down to a transform. I could choose counterclockwise, or if I want, I could come up here and choose rotate.
Bill Rosener: This is, gonna allow me to specify any angle I want, but in this case I am going to put that negative 90 degrees there.
Bill Rosener: Okay, at this point, if I wanted to change the color, I could go ahead and use the magic wand.
Bill Rosener: I can highlight kind of this pink.
Bill Rosener: I can go ahead and press on my foreground. Icon pick my new shade of color.
Bill Rosener: and I usually use the keyboard shortcut all backspace. But just go ahead and come up here to, or you can come up here and go edit. Fill
Bill Rosener: foreground color and press Ok
Bill Rosener: and control D, and there we go. So we now have
Bill Rosener: this arrow point and up, and it's blue. And if you ever want you, come over here and merge these 2 down if you wanted to. If you knew you weren't ever gonna touch this again, go ahead, merge that back into a single layer. You could then actually save it in index format. But typically I'm gonna go ahead and save this as a gift file, and that'd be the last step there. One thing you kinda notice is, maybe when zoomed in that kind of looks, so you kind of see the stair step approach. But
Bill Rosener: when I zoom back out. It's gonna look pretty well normal again.
Bill Rosener: Okay. Finally, again, the last step would be to open a file, save a copy.
Bill Rosener: and you could save it as a gift out, or maybe as a Png, I'd probably go with the Png. And
Bill Rosener: assignment
Bill Rosener: 17 dot, PNG.
Bill Rosener: And save it
Bill Rosener: well, hopefully. In this video, you learned how to take a navigation button. In this case an arrow point in one direction. We reverse or change the direction, and then we change the color. And I'll catch the next video. Thanks a lot.
