Hi All,

ImageEnIO := TImageEnIO.CreateFromBitmap(ABitmap);
ImageEnIO.Params.?

What params are assigned via the TImageEnIO component?
for example is IOParamsVals.TIFF_Compression assigned?

Thanks
Ron

Hi

When creating a TImageEnIO all Params will have the default value. Params are set when loading a file (LoadFromFile/LoadFromStream), loading the params only (ParamsFromFile/ParamsFromStream) assignment of params (Params.Assign).

So in your example above TIFF_Compression would have a default value.

Thanks Nigel,

Is there any way to populate the TIOParamsVals structure with a TIEBitmap?

If you loaded ABitmap from a file into ImageEnView you can assign the ImageEnView.IO.Params to ImageEnIO.Params. 
ImageEnIO.Params.Assign(ImageEnView.IO.Params);

or just assign each parameter you need:
ImageEnIO.Params.TIFF_Compression := ImageEnView.IO.Params.TIFF_Compression;

If ABitmap is assigned from memory you can modify any of the ImageEnIO.Params:
ImageEnIO.Params.Width := ABitmap.Width;
ImageEnIO.Params.Height := ABitmap.Height;

Also, when loading and saving TIEBitmaps you can also pass a TIOParamVals object to get/set the parameters:
