TppImage

edited August 2001 in General
I have a TppImage on a report. At OnPrint I load a file from the disk. If
the file is not found I do not want to print any image. I check for the
existance of the file with FileExist if true then I load it from disk if
false I want to clear the image. I used TppImage.Clear. I do not get any
error messages and the line of code runs but the image is not cleared. Is
this a problem? Is there another way to accomplish clearing the image
either before it is loaded from the disk or after it is printed?

Thanks

    One easy way to do this would be to set TppImage.Visible to True/False.

    TppImage basically works like Delphi's TImage. It has Picture property
    etc.

    I researched this and can find no way to clear the image other than to
    draw on the Picture.Bitmap.Canvas or resize it to 1 x 1 pixel (or both).

    BTW, the clear method is defined in an ancestor, but for Image is
    currently does nothing.
