Save File Thumbnail

[Josh]

@Andy90 When you right-click on a file in the asset browser there is an option to save the thumbnail as a PNG image.

local extension = {}

function extension.hook(event, extension)
    
    if event.id == EVENT_WIDGETACTION and event.source == extension.menu then
        if program.assetbrowser.selectedfile ~= nil then
            local file = RequestFile("Save File", CurrentDir().."/", "Portable Network Graphics:png", 1, true)
            if file ~= "" then
                local assetfilename = Lower(StripDir(program.assetbrowser.selectedfile.path))
                local n
                for n = 1, #program.assetbrowser.assetdisplays do
                    if program.assetbrowser.assetdisplays[n].panel:GetHidden() == false then
                        if Lower(program.assetbrowser.assetdisplays[n].label.text) == assetfilename then
                            local pixmap = program.assetbrowser.assetdisplays[n].thumbnail.pixmap
                            if pixmap == nil then
                                Print("Error: No pixmap found")
                                return true
                            end
                                pixmap:Save(file)
                            break 
                        end
                    end
                end
            end
        else
            Print("Error: No file selected")
        end
    end
    return true
