I am trying to replace the default SVG file loader with another SVG file loader. How can I change default SVG file loader to my own I am trying to use the following code: 


const
  ioSVG = ioUSER + 782; // to get a unique FileType number contact support@xequte.com

  procedure RegisterSVG();
  procedure ReadSVG(Stream: TStream; Bitmap: TIEBitmap; var IOParams: TIOParams; var Progress: TProgressRec; Preview: boolean);
  function  TrySVG(Stream: TStream; TryingFormat:TIOFileType): boolean;

procedure RegisterSVG();
var ff: TIEFileFormatInfo;
begin
  ff:= TIEFileFormatInfo.Create;
  ff.FileType:= ioSVG;
  ff.FullName:= 'Scalable Image Format';
  ff.Extensions:= 'svg';
  ff.InternalFormat:= True;
  ff.ReadFunction:= ReadSVG;
  ff.WriteFunction:= nil;
  ff.TryFunction:= TrySVG;
  IEFileFormatADD(ff);
end;


The ReadSVG is my routine for loading a SVG file and convert it to a Imageen Bitmap.

It is working for other file formats I have added like QOI and others but not for SVG and I need this for my thumbs browser.

Any ideas?

Hi Roy

Did you try removing the ioSVG format:

And then adding SVG as a custom format, e.g.

iormkSVG = 10001;
