SetResolutions Method

public void SetResolutions( 
   LeadSize[] resolutions
)

'Declaration
 

Public Sub SetResolutions( _
   ByVal resolutions() As LeadSize _
) 

'Usage
 

Dim instance As CodecsSaveOptions
Dim resolutions() As LeadSize
 
instance.SetResolutions(resolutions)

public void SetResolutions( 
   LeadSize[] resolutions
)

- (BOOL)setResolutions:(NSArray<NSValue *> *)resolutions //CGSize

public void setResolutions(LeadSize[] resolutions)

 function Leadtools.Codecs.CodecsSaveOptions.SetResolutions( 
   resolutions 
)

public:
void SetResolutions( 
   array<LeadSize>^ resolutions
) 

Parameters

resolutions

An array of LeadSize structures indicating the resolutions to save.

Currently, this only works with the JBIG format.

For JBIG, the maximum number of resolutions that can be saved is 29.

For a JBIG file, the values of different resolutions are implied because the dimensions of each resolution layer are half the dimensions of the one directly above it.

GetResolutions and SetResolutions are used to determine the highest resolution layer which will be saved in a file. You can fill the array with an actual width and height, or you can fill either the width or height with a valid value, and specify 0 for the other dimension to allow LEADTOOLS to calculate that dimension based on the image's aspect ratio during the next save operation. Note that for JBIG, all the values set in the array are stored, but only the first item is used during an actual file save process.

Ex.

uCount = 3 Resolution[0].Width = 800 Resolution[0].Height = 0

If you then save an image that is 1600 x 1200, the resolutions that are stored in the file would be:

800 x 600 400 x 300 200 x 150
