Base64ToStream

function Clomosy.Base64ToStream(ABase64:string):TclMemoryStream;

Base64ToStream is a function used to convert a Base64 string to a stream (TCLMemoryStream). This function takes a Base64 code and converts it to a TCLMemoryStream object, making the data readable.

For example, Base64ToStream function can be used to convert Base64-encoded data obtained from a file or over a network into a TCLMemoryStream. This allows the data to be processed using this stream or transferred elsewhere later.

Example
In the example, the data held in Base64 format within the TclMemo object is converted to a TCLMemoryStream object using the Base64ToStream function. This converted data is then transferred to a TclImage object.

 var
   Form1 : TCLForm;
   noteMemo : TclMemo;
   SourceImg : TCLImage;

 void memoBase64ToStreamClick;
 var
 LMemStream:TCLMemoryStream;
 {
   noteMemo.Lines.Text = Clomosy.FileToBase64(clPathCombine('apple.png',Clomosy.AppFilesPath));
   LMemStream = Clomosy.Base64ToStream(noteMemo.Lines.Text);
   SourceImg.Bitmap.LoadFromStream(LMemStream);
 }
 
 //------ Main Code ------
 {
   Form1 = TCLForm.Create(Self);
   Form1.AddAssetFromUrl('https://clomosy.com/demos/apple.png');
   
   noteMemo = Form1.AddNewMemo(Form1,'noteMemo','---');
   noteMemo.Align = alMostTop;
   noteMemo.Height = 400;
   noteMemo.StyledSettings = ssFamily;
   noteMemo.TextSettings.WordWrap = True;
   Form1.AddNewEvent(noteMemo,tbeOnClick,'memoBase64ToStreamClick');
   SourceImg = Form1.AddNewImage(Form1,'SourceImg');
   SourceImg.Align = alClient;
   Form1.setImage(SourceImg,'https://clomosy.com/learn/xMark.png');
   
   Form1.Run;
 }
