SaveResolutionHeight property (ILEADRasterIO)
|
float SaveResolutionHeight(short nIndex) | |
|
Overview |
Refer to Implementing JBIG Features |
Remarks
Specifies the height component of the resolution to write.
The array range is SaveResolutionWidth(0) to SaveResolutionWidth(SaveResolutionCount-1).
Currently, only the JBIG format uses these properties.
Note that for a JBIG save, only the first resolution is used. Each subsequent dimension up to SaveResolutionCount will actually be calculated as 1/2 the previous dimension. You can set this to 0 to use the default or, you can set this to 0 and set a value for the height component, and the width component will be automatically calculated for you based on the aspect ratio of the image being saved.
Ex.
SaveResolutionCount = 3
SaveResolutionWidth(0) = 800
SaveResolutionWidth(0) = 400
If you then save an image that is 1600 x 800, the resolutions that are stored in the file would be:
800 x 400
400 x 200
200 x 100
By default, the control will save images using the default of the file format. For JBIG only one resolution which has the size of the bitmap being saved will be saved.
The unit of measure is determined by the ScaleMode property.
