DontScalePixels Field




ImageGear.Core Assembly > ImageGear.Processing Namespace > ImGearScaleReductionOptions Class : DontScalePixels Field
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.
