Custom Splashscreen wrong color

Fuganater

Hello!

I'll do my best to explain but please tell me if more info is needed.

I followed this guide and it works but my splashscreen is the wrong color. I tried exporting as a bmp in GIMP and Paint (which is what the instructions say). I think the issue is the orange/yellow that I am using isn't being converted properly.

This is what it should look like.

But this is what it looks like when on the panel.

Looking forward to any help I can get!

@Fuganater Your can try the method described here: https://github.com/Duet3D/PanelDueFirmware#splash-screen

But wrong colors usually indicate that you picked the wrong firmware binary as a base. Which PanelDue do you have?

Point 1 - That method doesn't work because it is a 16-bit application and won't run on my 64-bit system.

Point 2 - The colors for the rest of the display is fine. It is just the logo that is the wrong color. I have the MKS 7" Duet Panel.

Try the bmp2c from https://github.com/Duet3D/PanelDueFirmware/tree/master/Tools/bmp2c/Release

@dc42 what command line would be used for that version of bmp2c ?

Phaedrux

Should be the same

rathorp80

@Phaedrux gives unkown option: -outfile error code -1

Phaedrux

Can you show what your entire command line was?

So I do that but it still shows up as the wrong color.

I also tried a much simpler version and it just flat out doesn't work at all. The display looks fine and works as it should. Just no image at boot up.

This is the image I was trying:

Since I am using RR 2.01, I'm using this version for the PanelDue: https://github.com/Duet3D/PanelDueFirmware/releases/tag/1.24

MY commands are:

bmp2c-escher3d.exe newbumblee.bmp newbumblee.bin -b -c

copy /b PanelDue-5.0i-7.0i-nologo.bin+newbumblee.bin PanelDueFirmware.bin

Perhaps take a look at https://github.com/frank26080115/PanelDueSplashMaker

While it is old, and not updated recently, it is still working even with the latest firmware versions. Simply go to its folder "release_binary" and download the file.

Place the file in an easy to access location and run it (I think it will download the Bossa and bmp2c-escher3d binaries automatically, on first run). It provides a simple to use interface:

Click on the Load Image and select your image (a preview will be shown).
Choose the "Local Files" tab (default is From Web, which gets the latest version, but may not work reliably).
In the Firmware Binary (nologo) File Path, browse to your firmware that you want to use.

The last step is what to do with the resulting firmware. If you want to save it, (for example to upload it with DWC in latest version firmwares, to flash it from ReprapFirmware), click the Save Resulting Firmware and choose your location. If you have the PanelDue directly connected to your (you might still have to save it), you can use the "Final Firmware Binary File Path" and its buttons to flash it (have not used this direct flashing).

This is what I use to create the splash screens for all my various printers.

This is odd. I just tried it on my Windows 10 Pro 64-bit and it runs just fine.

Can you please provide the original BMP you tried to convert so I can test what the issue is?

Fuganater

@wilriker

It won't let me upload a .bmp. I just converted these to .bmp in paint.

wilriker

@Fuganater I am not sure if the forum scaled your images but non has the required exact size of 800x480. That by itself will already be a problem.

You can attach the BMP if you put it into a ZIP file first.

@wilriker I did some for @Fuganater with this image but as bmp and he had same result

rathorp80

@rathorp80 wouldnt let me upload .zip of bmp

to upload either you would have to change the extension unfortunately.

Please try the tool linked by @Jacotheron

Make sure your image is exactly 800x480

@Jacotheron

While I did get this to work. The image still shows up blue. I also tried just a b/w image and it was very spotty. I may try to remake it at some point but I just don't have the time right now.

I really wish this was easier to do.

Phaedrux

@Fuganater well you can share the actual bmp file so we can see what format it's actually in.

Generally the image will look a lot better when you can match the reduced color pallet of the screen, so try setting your color pallet to 16 colors.

wilriker

To add to what @Phaedrux said (and correct a little): The splash screen does not have to adhere to the 16 color palette used for icons but it should work well within 16-bit color space (RGB 5-6-6).

Re spottiness: all of your images here contain a lot of compression artifacts. So I guess they all have been saved as JPG (or any other lossy-compression format) before being converted to BMP. This means all compression artifacts will end up in the BMP as well. And based on the 16-bit color space these will be more or less visible thereafter. So to create a clean splashscreen save the raw image (as created by whichever drawing application) as BMP (or at least PNG). This will avoid compression artifacts.

I'll have to do some googling because I have no idea how to do that.
