function ToRGBAlphaImage: TRGBAlphaImage; deprecated 'create TRGBAlphaImage and use TRGBAlphaImage.Assign'; |

Warning: this symbol is deprecated: create TRGBAlphaImage and use TRGBAlphaImage.Assign Create a new TRGBAlphaImage instance with RGB contents copied from this image, and alpha fully opaque. | |
|
function ToRGBFloat: TRGBFloatImage; deprecated 'create TRGBFloatImage and use TRGBFloatImage.Assign'; |
|
Warning: this symbol is deprecated: create TRGBFloatImage and use TRGBFloatImage.Assign Convert image to an TRGBFloatImage format. Generally this conversion is safe, since Single can express more-or-less precisely (and definitely uniquely) all values that Byte can express. (Yeah, we have autotest for this statement.) | |

constructor CreateCombined(const MapImage: TRGBImage; var ReplaceWhiteImage, ReplaceBlackImage: TRGBImage); |
|
Create image by merging two images according to a (third) mask image. This is a very special constructor. It creates image with the same size as MapImage. It also resizes ReplaceWhiteImage, ReplaceBlackImage to the size of MapImage. Then it inits color of each pixel of our image with combined colors of two pixels on the same coordinates from ReplaceWhiteImage, ReplaceBlackImage, something like
Pixel[x, y] := ReplaceWhiteImage[x, y] * S +
ReplaceBlackImage[x, y] * (S-1);
where S = average of red, gree, blue of color MapImage[x, y]. This means that final image will look like ReplaceWhiteImage in the areas where MapImage is white, and it will look like ReplaceBlackImage in the areas where MapImage is black. | |
