Subject: Re: Could not find a match for TImageScrollBox::TImageScrollBox()
In reply to: Roberto Pungartnik 's message, "Could not find a match for TImageScrollBox::TImageScrollBox()" on 14:17:56 07/29/05 Fri

you need to declare a type for the image to be loaded in.
I dont know c+ but in Delphi it is like this:

var
MyGraphic : TDibGraphic;

MyGraphic := TDibGraphic.create;

MyGraphic.loadfromfile('image.bmp');
MyGraphic.SaveToFile('SaveFile.jpg');


TDibGraphic is used for programmatically dealing with images, especially if you don't know the type of image ahead of time. ImageScrollbox is used for visual reading of images. Envision also includes other graphic types you can use, such as TJpegGraphic, TTiffGraphic, etc.

Hope this helps,
Dave
