I need to load a .png image because i need it's transparency. It's not an option to convert it for example in bmp because i lose it's transparency. How can I do that?
Just add an include for stdimage.hpp
.
At designtime, this will make .png files available in the Image.Picture
dialog. At runtime, you can create and load a TPngImage with the file, and assign it to the Image.Picture
.
#include <stdimage.hpp>
__fastcall TForm1::TForm1(TComponent* Owner)
: TForm(Owner)
{
TPngImage* img = new TPngImage();
img->LoadFromFile("C:\\Images\\calculator.png");
Image1->Picture->Assign(img);
delete img;
}
(Delphi code and explanation included as well as C++ Builder, because the TImage
and TPngImage
are both Delphi classes and therefore it's relevant, and because C++ Builder users should be pretty familiar with translating Delphi code as the entire VCL is built on it. Also, as TImage
is a Delphi VCL component, a Delphi user may find the question and find the information useful as well.)
procedure TForm4.Button1Click(Sender: TObject);
var
Png: TPngImage;
begin
Png := TPngImage.Create;
try
Png.LoadFromFile('C:\Images\calculator.png');
Image1.Picture.Assign(Png);
finally
Png.Free;
end;
end;
