LightBurn Tutorial 19 – Image Masking

0:00 in this video i’ll be going over the new

0:02 image masking functionality in the

0:04 latest version of light burn

0:06 so let’s say we’ve got this a picture of

0:07 an adorable puppy we’d like to

0:10 engrave it but leaving out the

0:12 background we just want the puppy

0:14 now previously the way that you would

0:16 have to handle this is to take the image

0:18 load it in some image editing software

0:20 crop it bring it back into light burn

0:23 then continue on with your workflow but

0:24 no more this is why we have image

0:26 masking

0:28 so the first thing i’m going to do is

0:29 select a tool layer if you’re not

0:30 familiar with those those are also new

0:32 to the

0:33 most recent versions of lightburn and

0:35 those work

0:36 just like a normal cut layer in terms of

0:38 the shapes and objects that you can draw

0:40 however they will never be output

0:43 they’re merely

0:43 for marking things off on your design or

0:46 doing things like this image mask

0:48 so i’m going to then go and select

0:50 rectangle

0:52 i’m going to draw a box around the puppy

0:55 and then select both of them i just use

0:57 ctrl a in this case because there’s only

0:59 two objects

1:00 right click and now as you can see

1:02 there’s an apply mask to image

1:04 you can also go to tools and have the

1:07 same option

1:08 so i’m going to apply that and as you

1:10 can see it brings it down to just that

1:12 rectangle size now the one thing that

1:14 you will note here

1:16 is that the selection box has not

1:17 changed it did not get any smaller

1:20 and that is because this is a mask

1:23 and not a crop and let me show you what

1:24 that means in this case i’m going to

1:27 click off to deselect everything and

1:29 then click just

1:30 on the mask rectangle that i created

1:34 and if i drag this around as you can see

1:36 it automatically updates it’s basically

1:38 providing a window into that image

1:40 and putting the image only where that

1:43 rectangle is i can even invert this

1:45 select just the image move the image

1:47 around

1:49 and it does the same thing so this is

1:51much more powerful because then you can

1:53 tweak it after the fact and it’s

1:54 completely non-destructive

1:57 for example i can actually go and draw

1:59 another shape

Tran script for LightBurn Tutorial – Image Masking (Cont…)

2:00 let’s say i want to make a frame i know

2:03 this is a terrible frame but i want to

2:04 make a frame and i want to have the

2:05 dog’s face at the top well

2:08 one thing that i’ll have to do first is

2:11 actually

2:11 remove the mask so we can go back here

2:13 i’m then going to

2:15 select that shape and the other one

2:19 and group it so note that if you want to

2:21 apply a mask

2:23 the shapes that you use have to all be

2:25 grouped if there’s multiple shapes and

2:27 they all have to be of the same cut

2:28 layer

2:30 now these are grouped i can select

2:32 everything again right click

2:34 apply mask to image and now as you can

2:36 see

2:37 again it’s providing that sort of fill

2:39 style window into the image and again

2:42 this

2:42 is completely movable

2:45 just as you would expect and if i go to

2:48 preview

2:51 as you can see it only engraves where i

2:53 have applied that mask

2:58 now if i instead wanted to actually cut

3:01 this out

3:02 instead of using a tool layer you could

3:04 then select

3:06 those shapes switch it to a normal cut

3:08 layer

3:09 and now that i’ve done this now this

3:11 will actually also cut along that line

3:13 if you wanted to cut it out

3:15 it just tool layers are sometimes

3:16 simpler if you don’t actually want to

3:19 cut where your mask is

3:21 so switch this back the other thing i

3:24 could do here and i’m going to remove

3:25 the mask again

3:27 is just to show you some of the

3:28 complexities that you can do with this

3:30 and delete this shape entirely

3:32 add some text

3:35 and then move that over the image

3:38 look at his nose right on the p there

3:41 select everything

3:42 right click apply mask and as you can

3:45 see it’s only going to engrave

3:47 where that text is it works just like

3:50 you would

3:50 on a fill but instead of a solid color

3:52 fill it’s going to be

3:53 basically an image fill now another

3:56 thing that you can do with this

3:58 is if you’ve done this and you want to

4:02 bake this in so to speak you know you’re

4:04 done you know that it’s perfectly

4:06 oriented and you want to kind of clean

4:07 things up you can actually right click

4:09 on the image and there’s also a

4:11 flattened image mask option

4:13 i can select that as you can see now the

4:15 selection box has shrunk

4:17 to just the size of the masking area and

4:20 that tool layer is gone from the cut

4:22 layers so this image

4:24 is just that we’ve literally removed all

4:26 of the other image data

4:28 other than what you wanted it to be so

4:31 that’s the image masking functionality

4:33 we hope you like it thanks
