Subject: Clear Graphic Image

I am trying to implement a program using Borland C++Builder 6 and 2 Envision Image Library controls (Version 2, beta 1) to display tiff files. I execute the following code when I get new images to display. The first set of images display with no problem but I am unable to clear the images to display the subsequent images. Can you please tell me what I am doing wrong…

I've tried Clear().
I've disabled and enabled the control.
I've loaded the information into a new TImageScrollBox and assigned its graphic to the control.
I have set graphic and DisplayedGraphic to NULL.

Nothing I have done will allow me to change the original image. After I have done the load from file, I still have the original image displayed.

Best regards,

Chuck Latham

AnsiString filepath = ExtractFilePath(Application->ExeName);
if (FileExists(filepath + "Front.tif"))
AnsiString fn = filepath + "Front.tif";
ISBFront->LoadFromFile(fn, 0);
DeleteFile(filepath + "Front.tif");
CheckImageAvailable = true;
ISBFront->Visible = true;
ISBFront->Visible = false;
if (FileCheckRetry < 20)
fileTimer->Enabled = true;
if (FileExists(filepath + "Back.tif"))
AnsiString fn = filepath + "Back.tif";
ISBBack->LoadFromFile(fn, 0);
ISBBack->Visible = true;
DeleteFile(filepath + "Back.tif");
ISBBack->Visible = false;
