GetImage()

WARNING: graphics.DrawImage() or GDI cannot draw an image that is too big, typically with an area larger than 10,385,000 pixels (Jiro estimated > 40000 pixels). This means it cannot handle recording sonograms longer than 2 minutes. Therefore call a recursive method to draw the image.

Declaration

public Image<Rgb24> GetImage()

Returns

Type	Description
SixLabors.ImageSharp.Image<SixLabors.ImageSharp.PixelFormats.Rgb24>

OverlayScoresAsRedTransparency(Image<Rgb24>, Double[,])

It is assumed that the spectrogram image is grey scale. NOTE: The score matrix must consist of reals in [0.0, 1.0]. NOTE: The image and the score matrix must have the same number of rows and columns. In case of a spectrogram, it is assumed that the rows are frequency bins and the columns are individual spectra.

Declaration

public static Image<Rgb24> OverlayScoresAsRedTransparency(Image<Rgb24> bmp, double[, ] hits)

Parameters

Type	Name	Description
SixLabors.ImageSharp.Image<SixLabors.ImageSharp.PixelFormats.Rgb24>	bmp	the spectrogram image.
Double[,]	hits	the matrix of scores or hits.

Returns

Type	Description
SixLabors.ImageSharp.Image<SixLabors.ImageSharp.PixelFormats.Rgb24>

OverlayScoresAsRedTransparency(Image<Rgb24>, Int32[,])

Overlays a matrix of scores on an image, typically a spectrogram image. It is assumed that the spectrogram image is grey scale. NOTE: The score matrix must consist of integers from 0 to 255. NOTE: The image and the score matrix must have the same number of rows and columns. In case of a spectrogram, it is assumed that the rows are frequency bins and the columns are individual spectra.

Declaration

public static Image<Rgb24> OverlayScoresAsRedTransparency(Image<Rgb24> bmp, int[, ] hits)

Parameters

Type	Name	Description
SixLabors.ImageSharp.Image<SixLabors.ImageSharp.PixelFormats.Rgb24>	bmp	the spectrogram image.
Int32[,]	hits	the matrix of scores or hits.

Returns

Type	Description
SixLabors.ImageSharp.Image<SixLabors.ImageSharp.PixelFormats.Rgb24>	The new image with overlay of scores as red transparency.
