@aliarokapis:matrix.orgAlexandros LiarokapisJust wanted to get the bounding boxes right for this :P17:54:20
@aliarokapis:matrix.orgAlexandros LiarokapisThanks for the suggestion though!17:54:31
@sirhcel:matrix.orgsirhcelNow i see. This looks awesome! Is the whole ui seem in the window rendered with embedded graphics?18:48:01
@aliarokapis:matrix.orgAlexandros LiarokapisNo, main UI is based on the Juce c++ framework for VSTs19:02:14
@aliarokapis:matrix.orgAlexandros LiarokapisI use rust bindings to bridge the main engine19:02:42
@aliarokapis:matrix.orgAlexandros LiarokapisAlso acts as an emulator for the hardware, the small display will be the part actually handled by embedded graphics.19:03:41

@jo_we:matrix.orgjo_weHey there, id like to load a custom font into embedded-graphics. I've found that i can just create a mono_font::MonoFont for that, though what format is the raw file embedded-graphics uses? I cant seem to open it with a classical raw viewer?08:29:56
@jamesmunns:beeper.comJames Munnsiirc it is a plain binary bitmap, https://github.com/wezm/profont might be useful to look at as an example08:47:27
@jamesmunns:beeper.comJames MunnsI think they also have some debug tooling you can poke around to see how it is done08:47:57
@jo_we:matrix.orgjo_weoooh yea they have tooling for conversions. thats super cool, how did i miss this? thanks, I'll fiddle around with it!08:48:33
@wezm:matrix.orgwezmNote that some of my tooling only works for OpenType fonts with embedded bitmaps, it won’t work for scalable fonts (which is most of them) without hooking up a rasteriser. 10:06:03

@jo_we:matrix.orgjo_weThanks for your help! i managed to get my fonts in a while ago! Ive got another question: is there a way using embedded-graphics to invert a section of my drawtarget?13:04:48

@avsaase:matrix.orgAlexander van Saase Has anyone tried to use the epd-waveshare driver with WeAct displays from AliExpress? I have the 2.9 inch version and it looks like I'm able to control it but the colors are inverted. I not sure if this a bug, the driver is not compatible or if I'm doing something wrong. 19:07:08

@hans_l:matrix.orgHans LarsenHey. Just found this matrix room. I have a PR that's been inactive for close to a year but is still passing and it still works; https://github.com/embedded-graphics/simulator/pull/48 Who should I talk to to get this moving forward?20:18:09
@hans_l:matrix.orgHans LarsenI really think this PR would be very useful, and it's backward compatible.20:18:27

Apart from the

                    if window_id != window_id {
                        return None;
                    }

I think it's ok :)

@almindor:matrix.orgalmindorLGTM, I don't have the rights tho17:14:36

@hans_l:matrix.orgHans LarsenFixed the example and propagating of window events. I think it's awkward to have its own event system and not have all events sent to the app, but I didn't change the behaviour in the PR, just added a TODO19:58:56

@avsaase:matrix.orgAlexander van SaaseHi everyone, I wrote a new driver for the WeAct Studio e-paper displays you can get in AliExpress for quite cheap. I'm waiting for the two displays with red color support to test if they work correctly before I make a release. If you have one of these displays lying around you can already try it out. Let me know if you have any feedback. https://github.com/avsaase/weact-studio-epd08:31:15

@dominaezzz:matrix.orgDominic FischerAnyone know of a no_std crate that can decode JPEG into a plain RGB framebuffer?11:11:07
