ImageGear v26.3 - Updated
ImageGear.Core Assembly / ImageGear.Processing Namespace / ImGearScaleReductionOptions Class / DontScalePixels Field




In This Topic
    DontScalePixels Field
    In This Topic
    Set to true to avoid scaling the pixel values.
    Syntax
    'Declaration
 
Public DontScalePixels As Boolean
    'Usage
 
Dim instance As ImGearScaleReductionOptions
Dim value As Boolean
 
value = instance.DontScalePixels
 
instance.DontScalePixels = value
    public bool DontScalePixels
    public: bool DontScalePixels
    public:
bool DontScalePixels

    Field Value

    Boolean value.
    Remarks
    In this case, the component values of each pixel will be preserved (within the limits of precision) even though their effective ranges may be different. For example, if you have a 16bpp grayscale image but each pixel value actually only ranges from 0-255, and you want 0 to represent black and 255 to represent white, it makes sense to set this option to true and avoid scaling the values. If scaling were used in such a case, the image would appear black since the brightest possible value (255) would be scaled down to almost nothing: (255/65535) * 255 = 1.
