Hi guys

as i created a code which is for finding empty or blank spaces in project.

so i follow these steps.

• select all events
• add regions on every event
• invert regions
• deselect events

so those inverted regions will be EMPTY SPACES in project.

but my invert region code is not doing it accurately

look

so can anybody fix it ??

this is the code i am using

private void InvertRegions(Vegas vegas)
{
    var regions = vegas.Project.Regions;

    // Calculate the project length
    Timecode projectLength = vegas.Project.Length;

    // Create a list to hold the new regions to be added
    var newRegions = new List<ScriptPortal.Vegas.Region>();

    // Calculate the total number of regions to process
    int totalRegions = (regions.Count > 0) ? (regions.Count + 2) : 1; // +2 for potential start and end regions

    // Add a new region from the start of the project to the first existing region
    if (regions.Count > 0)
    {
        var firstRegion = regions[0];
        if (firstRegion.Position > Timecode.FromNanos(0))
        {
            var newRegion = new ScriptPortal.Vegas.Region(Timecode.FromNanos(0), firstRegion.Position, "Empty Space");
            newRegions.Add(newRegion);
        }
    }
    else
    {
        // If there are no existing regions, add a single region covering the entire project
        var newRegion = new ScriptPortal.Vegas.Region(Timecode.FromNanos(0), projectLength, "Empty Space");
        newRegions.Add(newRegion);
    }

    // Add regions in the gaps between existing regions
    for (int i = 0; i < regions.Count - 1; i++)
    {
        var currentRegion = regions[i];
        var nextRegion = regions[i + 1];

        if (nextRegion.Position - currentRegion.Position - currentRegion.Length > Timecode.FromNanos(0))
        {
            var newRegion = new ScriptPortal.Vegas.Region(currentRegion.Position + currentRegion.Length, nextRegion.Position - currentRegion.Position - currentRegion.Length, "Empty Space");
            newRegions.Add(newRegion);
        }
    }

    // Add a new region from the end of the last existing region to the end of the project
    if (regions.Count > 0)
    {
        var lastRegion = regions[regions.Count - 1];
        if (projectLength - (lastRegion.Position + lastRegion.Length) > Timecode.FromNanos(0))
        {
            var newRegion = new ScriptPortal.Vegas.Region(lastRegion.Position + lastRegion.Length, projectLength - (lastRegion.Position + lastRegion.Length), "Empty Space");
            newRegions.Add(newRegion);
        }
    }
    regions.Clear();

    // Add the new regions
    foreach (var newRegion in newRegions)
    {
        regions.Add(newRegion);
    }
}
