- Introduction
Delphi Builder components for preparing and burning images to CD, DVD, and Blu-ray optical storage media. Uses standard Windows Image Mastering API 2.
2. Components in the Demo and what they do
The Demo contains some labels with text, as well as TEdits for the directory paths and file names. The ‘Create Image’ button call the button onClick event, which executes the Write process. In the next code you can see the execution in details.
procedure TFormDemo.ButtonCreateImageClick(Sender: TObject);
begin
Cancel := False;
ProgressBar.Position := 0;
UpdateControls(True);
try
DiscImage.VolumeName := EditVolumeName.Text;
DiscImage.SourceTree := EditSourceTree.Text;
DiscImage.Write(EditImageName.Text);
finally
LabelStatus.Caption := '';
UpdateControls(False);
end;
end;
The Main component that does the Image Writing is the TDiscImage component by Winsoft. Depending on the TRadioGroup choice, the user chooses between two file systems – ISO 9660 and UDF. When one of the files systems is marked, an onClick event is fired with code:
procedure TFormDemo.RadioGroupFileSystemClick(Sender: TObject);
begin
if RadioGroupFileSystem.ItemIndex = 0 then
DiscImage.FileSystems := [fsISO9660]
else
DiscImage.FileSystems := [fsUDF];
end;
