LightBurn File Formats Demo 06 – SVG and DXF and More

0:00 so it’s been a little while and I

0:02 thought it was time to do another

0:04 LightBurn demo quite a bit has happened

0:07 lately let’s see first of all SVG

0:12 support I’ve got if I just drag and drop

0:16 an SVG in we’re handling creating new

0:21 layers cut layers based on the distinct

0:24 colors in the SVG file I do the same

0:26 thing with Adobe Illustrator files

0:29 handling arc circles ellipses rectangles

0:33 pretty much everything in the file and

0:37 if I go into node edit mode you can see

0:40 like the arcs are actually proper

0:42 splines and so on that is my dog going

0:48 crazy behind me what else

0:53DXF I have also added support for DXF I

0:58 can drag and drop a DXF just like I

1:01 could anything else now a lot of

1:03 software that exists looking at you

1:06 Inkscape does kind of a crappy job with

1:08 DXF files so if you look at this this is

1:11 all tiny little line segments being

1:15 exported as just bits and pieces so in

1:19 order to help out with that I’ve added

1:22 tools to do joining so if you look at

1:25 this

1:25 I just auto joined it and so now this is

1:30 distinct shapes this one is actually

1:32 kind of a bad example because there’s

1:34 spots here in the file where there’s an

1:36 overlap however it’s a whole lot better

1:39 than it was before the other thing that

1:42 a lot of DXF exporters do is they create

1:46 really really dense objects so tons of

1:49 points even points that are in a

1:51 straight line which is really silly and

1:54 I’m not sure why anybody would do that

1:56 however light burn now has an optimized

2:00 function so you click the button and now

2:03 you have recovered splines and recovered

2:06 lines and

2:08 generally speaking it just looks a lot

2:10 better this also makes for a

2:13 significantly smaller file the original

2:15 file with this density of points saves

2:18 to about a megabyte and a half with this

2:22 point density it saves to just under 250

2:25 K so that’s pretty significant it’s also

2:29 worth mentioning that light burn is kind

2:32 of fast I have a spire I am a registered

2:38 user you can see my name up here if I

2:41 take one of my generated Mac file here

2:50 so I have a file that I made with half

2:55 toner which you may have heard of this

3:00 file is kind of an iconic truck image

3:03 that people use for image bathing it’s

3:08 got a lot of circles in it and you can

3:10 see when I’m trying to zoom in or even

3:12 just navigate around aspire which is a

3:15 $1500 piece of software is kind of

3:19 choking dragging the view is going

3:22 pretty pretty slow doing operations on

3:25 this stuff takes quite a while if i zoom

3:26 in it takes a really long time so notice

3:32 that also pay attention to how long it

3:40 takes so I’m about to drop and the

3:44 import happens relatively quick but then

3:46 navigating is pretty slow

3:49 compare that to light burn so here’s the

3:53 same file in light burn drop I can zoom

3:57 move around navigate pan select I have

4:04 to ungroup them they come in grouped

4:06 automatically move them around so on and

4:11 so on and so on

4:12 light burn is really fast and it’s been

4:15 authored to be really fast I pay

4:18 attention to these things I have a game

4:20 development

4:21 background so I’m actually a little bit

4:23 anal about making things quick and you

4:26 know that’s the bulk of what’s really

4:31 new in general there have been a lot of

4:35 bug fixes lately I still have a bunch of

4:38 stuff to do for DXF files I feel like

4:42 SPG’s are working quite well most SVG

4:46 files that I’ve thrown at it just work

4:47 now so this world map the Korean so on

4:58 and so on and so on there’s quite a few

5:01 files that I’ve tried it with and they

5:04 all seem to be fine so I think SVG

5:08 support is pretty good I’m not dealing

5:11 with a lot of what’s in an SVG file

5:14 because I don’t support things like

5:16 gradients and different stroke widths

5:18 and fills and stuff like that so it’s

5:20 easier for me to handle it then

5:22 something like Inkscape but that said

5:24 I’m still doing a fairly decent job of

5:26 it anything else don’t think so like I

5:33 said a bunch of bug fixes have happened

5:36 recently just general cleaning up for

5:41 example if I quit when I restart lightburn

5:46 remembers the position and size

5:48 and layout of my window that didn’t

5:50 happen before lots of small details like

5:53 that that are more usability things than

5:57 anything changed a couple of the icons

5:59 have moved a couple of things so like

6:01 preview is up here now which makes a

6:03 little more sense font is down here it

6:05 used to be up here but I kept actually

6:08 trying to click down here because this

6:10 is where all the tools are so it’s

6:15 coming along progress is being made I am

6:17 hoping for a release probably middle of

6:22 November so thanks for watching
