I am trying to ooad a bmp image from disk. Whe the line:

Image k=BMPEncoder::NewBmp()->LoadImageFile("OffIMG.bmp");

is compiled the compiler presents the error:

(...) error: `NewBmp' is not a member of `Upp::BMPEncoder'

Which is the easy way to load a bmp image from disk into a Image type variable? Source code would be appreciated.

Many thanks

Alex

Do you mean:

Image k = ::LoadImageFromString(GetExeDirFile("Bruma.bmp"));

?

tab1.labelNumero.SetImage(k);
tab1.labelNumero.Refresh();

LoadImageFromString always return NULL ...

Any help?

alex100: why "from string"?
I think that function does expect the data of image to be in the string passed as argument, while you are giving it the name of file, not the data.

(but I didn't check the code or documentation, so I may be wrong)

Cant load jpg images using that code Sad

Image k = StreamRaster::LoadFileAny(GetExeDirFile("1025.jpg"));
if(k==Null)
{
PromptOK("NULL received");
}
This doeanst load the image. Returns null but the file exists in the exe directory

This code:

Image k = StreamRaster::LoadFileAny(GetExeDirFile("foto1.png"));
if(k==Null)
{
PromptOK("NULL received");
}
Works well, why?

Thanks

Alex
