Detailed Description

A view on an image with multiple levels of detail (LOD).

It is also usually called a pyramid of resolutions

• level 0 always gives the original resolution of the image
• image resolution at level N+1 is always lower than resolution at level N

Member Function Documentation

Dispose()

override void IOLink.LodImageView.Dispose ( bool  disposing )

inlineprotectedvirtual

Reimplemented from IOLink.View.

GetLevelRange()

virtual Vector2i64 IOLink.LodImageView.GetLevelRange ( )

inlinevirtual

Give the range of available levels of resolution Level 0 is always in the range. (because it corresponds to the original image) First value of returned vector is the level corresponding to the highest resolution (inferior or equal to 0) Second value of returned vector is the level corresponding to the lowest resolution (superior or equal to 0)

• a negative level (< 0) gives a higher resolution of the original image
• a positive (> 0) level gives a lower resolution of the original image

  Returns

  a vector of 2 values (high-res level, low-res level)

Resolution()

virtual ImageView IOLink.LodImageView.Resolution ( long  level )

inlinevirtual

An ImageView of the n-th level of detail.

Parameters

level

the level of detail

Returns

ImageView corresponding to given level

Exceptions

Error

if required level is not handled (out of range)
