Question

我在How to store images in FireMonkey?找到了从资源文件加载位图的解决方案我试图在我的Firemonkey应用程序中使用它，但它找不到资源并引发错误“EresNotFound”。我的资源.RC文件就像这样

Bitmap_1    BITMAP    "Test.bmp"

我的代码是

procedure Tform1.load_image_from_resource(var Im1: Timage; res_name: String);
var InStream: TResourceStream;
begin
  InStream := TResourceStream.Create(HInstance, res_name,RC_RTDATA);
  try
    Im1.Picture.Bitmap.LoadFromStream(InStream);
  finally
    InStream.Free;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Load_image_from_resource(Image1,'Bitmap_1');
end;

我还在问题Delphi 2010: unable to find resource - EResNotFound上找到了解决方案。但它仍然没有找到资源

Answer 1

您的代码中存在多个问题，您需要将资源声明为RCDATA

Bitmap_1    RCDATA    "Test.bmp"

另外看起来你创建了VCL应用程序并且资源类型名称中有一个拼写错误，它应该是RT_RCDATA，工作FireMonkey代码看起来像这样

procedure Tform1.load_image_from_resource(var Im1: Timage; res_name: String);
var InStream: TResourceStream;
begin
  InStream := TResourceStream.Create(HInstance, res_name, RT_RCDATA);
  try
    Im1.Bitmap.LoadFromStream(InStream);
  finally
    InStream.Free;
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Load_image_from_resource(Image1, 'Bitmap_1');
end;

从资源加载位图
