Leadtools.Codecs Namespace > CodecsSaveOptions Class : GetResolutions Method




Gets the resolutions to save when saving multi-resolution files.

Syntax

Visual Basic (Declaration) 
Public Function GetResolutions() As Size()
Visual Basic (Usage)Copy Code
Dim instance As CodecsSaveOptions
Dim value() As Size
 
value = instance.GetResolutions()
C# 
public Size[] GetResolutions()
Managed Extensions for C++ 
public: Size[] GetResolutions(); 
C++/CLI 
public:
array<Size> GetResolutions(); 

Return Value

An array of Size structures indicating the resolutions to save.

Example

For an example, refer to CodecsOptions.

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

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
