Method Detail

setImageWidth

public void setImageWidth(int inWidth)
Set the width of the image to retrieve. The data source can use this information to generate the appropriate rastor shapes. Several shapes may be generated or just one that cover this area. This is just a suggestion.


setImageHeight

public void setImageHeight(int inHeight)
Set the height of the image to retrieve. The data source can use this information to generate the appropriate rastor shapes. Several shapes may be generated or just one that cover this area. This is just a suggestion.
