Test Images

ImageEnView1.IO.LoadFromFile( 'D:\ImageTest1.jpg' );

  

AlphaFill

// Gradient fill the alpha channel with fully transparent on the left to fully opaque on the right
ImageEnView1.Proc.AlphaFill( 0, 255, gdHorizontal );

  

CastAlpha

// Flood file transparency from the top-left of the image
ImageEnView1.Proc.CastAlpha( 0, 0, 0, 50 );

  

CastAlphaRange

// Reduce number of alpha values to 4 (i.e. 2-bit alpha)
alphaCount := 4;         // Number of alpha channel values
a := 255 / alphaCount;   // Range of each alpha band
ImageEnView1.LockUpdate();
ImageEnView1.IEBitmap.AlphaFill( 0, 255 );  // Add an alpha gradient to the image
for i := alphaCount - 1 downto 0 do
  ImageEnView1.Proc.CastAlphaRange( Round( i * a ), Round( (i+1) * a ), Round( (i+1) * a ));
ImageEnView1.UnlockUpdate();

  

CastColor

// Perform a red flood fill starting at 0,0 (with a tolerance of 10)
ImageEnView1.Proc.CastColor( 0, 0, clRed, 10 );

  

CastColorRange

// Change all dark values (from dark gray to black) to black
ImageEnView1.Proc.CastColorRange( CreateRGB(0, 0, 0),
                                  CreateRGB(100, 100, 100),
                                  CreateRGB(0, 0, 0));

  

FeatherAlphaEdges

// Make colors similar to white transparent and then feather the alpha edges
ImageEnView1.Proc.SetTransparentColors( CreateRGB( 156, 156, 156 ), CreateRGB( 255, 255, 255 ), 0 );
ImageEnView1.Proc.FeatherAlphaEdges( 10 );

  

Fill

// Fill selection with red
ImageEnView1.Proc.Fill( clRed );

  

GradientFill

// Fill selection with a yellow to red vertical gradient
ImageEnView1.Proc.GradientFill( clYellow, clRed, gdVertical );

  

PaintMark

// Draw a black pixel every 10 pixels horizontally and vertically
ImageEnView1.Proc.PaintMark( 10, CreateRGB(0, 0, 0) );

  

inPaint (IEVision)

// Inpaint an area of the image (to fill missing areas of image or erase blemishes)
ImageEnView1.IEBitmap.GetIEVisionImage().InPaint( selRect.Width, selRect.Height, ipRect, rangeSize, ievINPAINT_TELEA );
ImageEnView1.Update();

Random

// Fill with pixels of random values (Gaussian distribution)
ImageEnView1.Proc.Random();

  

RemoveChromaKey

// Load Chroma-Key image
ImageEnView1.IO.LoadFromFile( C:\ChromaKey.jpg );



// Guess the background color
KeyColorRGB := ImageEnView1.Proc.GuessChromaKeyColor();

// Remove Chromakey from the image (will become transparent)
ImageEnView1.Proc.RemoveChromaKey( KeyColorRGB, 0.21, 30, 2, 0 );

SetTransparentColors

// Make colors similar to white transparent
ImageEnView1.Proc.SetTransparentColors( CreateRGB(255, 255, 255), 50, 0 );
