The number of neighbor pixels to be included in the convolution mask is specified by width. The standard deviation of the gaussian bell curve is specified by sigma

GM16ImageMBS.gaussianBlurChannel(channel as Integer, width as Double, sigma as Double)

The number of neighbor pixels to be included in the convolution mask is specified by width. The standard deviation of the gaussian bell curve is specified by sigma.

GM16ImageMBS.getChromaBluePrimary(byref x as Double, byref y as Double)

GM16ImageMBS.getchromaGreenPrimary(byref x as Double, byref y as Double)

e.g. x=0.3, y=0.6

GM16ImageMBS.getConstPixels(x as Integer, y as Integer, columns as Integer, rows as Integer) as Ptr

GM16ImageMBS.GetEXIFOrientation(byref orientation as integer) as boolean

Orientation is set to number from 0 to 8 depending on rotation. -1 if unknown.
This function can only read orientation, if there is an EXIF block in image.
Returns true for success and false for failure.

For new development, please use ExifTagsMBS class instead.

GM16ImageMBS.getPixels(x as Integer, y as Integer, columns as Integer, rows as Integer) as Ptr

Var f as FolderItem = SpecialFolder.Desktop.Child("test.jpg")
Var g as new GM16ImageMBS(f)

// get pointer to some pixels to write
Var x as ptr = g.getPixels(0, 0, 100, 100)

// draw a red line to the pixel buffer
Var o as Integer
for i as Integer = 0 to 99
  o = 100 * i + i
  x.UInt32(o * 4) = &hFFFF0000
next

// write back
g.syncPixels

// show
me.Backdrop = g.CopyPicture

Modified pixels may be subsequently transferred back to the image via syncPixels. This method is valid for DirectClass images.

GM16ImageMBS.Graphics as GM16GraphicsMBS

Var g as new GM16GeometryMBS(500,500)
Var c as new GM16ColorRGBMBS("white") // white
Var image as new GM16ImageMBS(g, c)

image.strokeColor = new GM16ColorRGBMBS("red") // Outline color
image.fillColor = new GM16ColorRGBMBS("green") // Fill color
image.strokeWidth = 5

Var draw as GM16GraphicsMBS = image.Graphics

// Draw a circle
draw.Circle(250, 250, 120, 150)

Backdrop=image.CopyPicture

Using the graphics object you can draw on the image.
