P: SDK ignores values set in updateExportSettings function (Timelapse plugin)

This is in a plugin I'm working on. I'm very inexperienced. This is the first plugin I'm writing. So a mistake on my part is definitely possible.

My plugin looks something like this. I hope I didn't leave out anything essential:

local Plugin = {
    hideSections = { "exportLocation", "fileNaming", "metadata", "video" },
    allowFileFormats = { "TIFF" },
    allowColorSpaces = nil,
    exportPresetFields = {}
}
function Plugin.startDialog( propertyTable )
    propertyTable.LR_format = "TIFF"
    propertyTable.LR_tiff_compressionMethod = "compressionMethod_None"
end
function Plugin.processRenderedPhotos( functionContext, exportContext )
    local exportSession = exportContext.exportSession
    local nPhotos = exportSession:countRenditions()

    local failures = {}
    for _, rendition in exportContext:renditions{ stopIfCanceled = true } do
        local success, pathOrMessage = rendition:waitForRender()
    end
end

pathOrMessage will be a path to a file in a temporary location where the name ends in .jpg and testers indicate to me that the file is in fact a JPEG file.

I have not observed this on my own Windows workstation and have limited access to a OSX machine under the current conditions.

Also, thanks for the quick response 🙂

Oliver, are you seeing this problem with a plugin you wrote or using the LR user interface?

Is it possible that there has been a regression on this? Because I'm seeing the exact behavior where I'm requesting a TIFF to be exported, but I'm receiving a .jpg file after the export. Although I'm only seeing that behavior on OSX, not on Windows.

"Adobe seems to have deleted the Lightroom SDK forum."

Unfortunately, all of the scripting and SDK forums were merged into their parent forums as part of the ugly migration from the Jive platform to Khoros.   Most of the old LR SDK forum content is still there, though it's much harder to search, and it's much harder for a plugin developer to monitor just SDK content.

Regardless, this forum (the official feedback forum) is the place to post bug reports.

This should be resolved by the 9.1 update released earlier today. Please give it a try and let us know if you still see the issue after updating.  Thank you for your patience!

I can confirm this problem, it's a big issue for me and the users of my software who rely on my Custom Export Plugin for Lightroom.

Here is a sample ServiceProvider script:

local LrDialogs = import 'LrDialogs'
return {
    showSections = 
        { 'fileNaming', 'imageSettings', 'exportLocation' },

    updateExportSettings = function( exportSettings )
        LrDialogs.message("Called") -- this will be called, 
                                    -- but still the exportSettings
                                    -- won't be changed 
                                    -- export will happen in JPG.
        exportSettings.LR_format = "TIFF"
    end,

    processRenderedPhotos = function( functionContext, exportContext )
        local exportSession = exportContext.exportSession
        local renditions = exportSession:renditions{ stopIfCanceled = true }
        for i, rendition in renditions do
            success, pathOrMessage = rendition:waitForRender()
        end
    end
}

If the Plugin is being called by a preset, which sets format = "TIFF", it will show the right format (tiff) in the dialog, but then still export jpgs.

I'd really appreciate if a fix could be provided asap! Thank you!

Hi Allen,

Thanks for reporting the issue.
We'll investigate and get back to you.

Meanwhile, Can you provide a sample script to replicate the issue?

Thanks,
