Parameters

resolutions
An array of Leadtools.LeadSize structures indicating the resolutions to save.
Remarks

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
            

Example
For an example, refer to CodecsOptions.
