ImageEn, unit imageenio




procedure SaveToFileICO(const FileName: WideString);


Saves the current image to a file in ICO format. ICO format allows storing multiple images with different resolutions and sizes.

FileName is the file name including extension.
ImageEn creates for you the sub-images to save, you have only to set the Params.ICO_BitCount and Params.ICO_Sizes arrays.
To control each image separately, use the IEWriteICOImages function.

- If an internal save error is encountered Aborting will return true. Saving issues due to insufficient write permissions and disk write failures will raise an exception.
- To abort while saving set Aborting to true
