Does anyone here work on Superslicer?

@resam is the Cura plugin for QOI thumbnail images available yet? If it is then I will mention it in 3.4.0rc1 release announcement.

resam

@dc42 could you test this generated file - to make sure it works, before I submit the plugin to Ultimaker for review: debug.gcode

I still don't know which image resolutions you want, so right now it contains:

64x64
128x128
160x160
256x256

Ultimaker Marketplace Review usually takes a few days, but you can alway install the plugin in manually with these instructions https://github.com/Kriechi/Cura-DuetRRFPlugin/#manual-installation
You can add that to the release announcement now.

@resam there's a problem with it, the start comment should be

; thumbnail_QOI begin

instead of

; thumbnail_OQI begin

and the end comment should read

; thumbnail end

instead of

; thumbnail_OQI end

Then it should work as expected.

resam

@chrishamm lol - yeah, good idea of mine to ask for a sanity check Thanks for catching that typo!

I'll ask again about resolutions: what do you want, or what can you/DCW/RRF/DSF handle? I read that PanelDue can do a max. of 160x160.

Actually that typo was made by the devs of PrusaSlicer; but they later corrected it.

I don't have a latest build of PrusasSlicer, so I don't know whether they use thumbnail_end or thumbnail_QOI end.

resam

@dc42 indeed! https://github.com/prusa3d/PrusaSlicer/commit/086662b6a1c7d7a14e35a90e6d46445f6871ac24 fixes it - so I probably copy-pasted it.

The end tag is the same tag as the begin, so thumbail_QOI. See https://github.com/prusa3d/PrusaSlicer/commit/87cff55856ae14096cd57f8e2542f1f1caef7167#diff-e09699df9f3fa4c292ba50b9f88dffe95b2d2d5c0a58d9d81441f9da5031c97bR49

WIP: Implemented support for QOI G-code thumbnail format as requested
by the RepRapFirmware team due to their low RAM budget for decompression.
Bundled the QOI image compression library.

@resam thanks for that. We'll need to change RRF and probably DSF then.

resam

@dc42 ok - my Cura plugin behaves the same way as PrusaSlicer.

resam

@dc42 please also update the code comment at https://github.com/Duet3D/RepRapFirmware/blob/09bf6d01b6028c7d7d162f0e2b60ca8a07849901/src/Storage/FileInfoParser.cpp#L959-L961

and am I reading RRF constant MaxThumbnails = 3 correctly, that the fourth thumbnail will not be parsed by RRF? My Cura plugin currently outputs 4 sizes... so again my question about resolutions?

chrishamm

@resam That limitation applies to RRF but not DSF. For the DWC filelist the ideal resolution is 48x48px and there is no real upper limit for previews. For PanelDue the maximum thumbnail height appears to be 6 x rowTextHeight. That means we have effective height limits of 126px for small displays and 192px for larger displays.

dc42

For PanelDue the recommended image size is 160x160 pixels. That size works on all three screen sizes.

ecause QOI for

I work with ideamaker and have the possibility to add content of data into gcode file. Thumbnail 640x640 or any other value.

Would be nice if it would be used on your side.

thx

@icy_snake for PanelDue the optimum size is 160x160. DWC can use a wider variety of sizes, however RRF can only use the first 3 thumbnail images in the file.

Anyone got a "sample gcode" with some sort of thumbnail that they can share just to see how the thumbnails look on DWC / Paneldue?

resam

@exerqtor https://github.com/Duet3D/DuetSoftwareFramework/blob/v3.4-dev/src/UnitTests/File/GCodes/Thumbnail_QOI.gcode

ICY_SNAKE

@resam Here is a sample code
Box_2_led-rar.txt

rename to .rar

includes a 160x160 thumbnail in the gcode plus an thumbnail for octoprint and Mainsail.
