The image reader is not registered for this image format

Hi!

Very simple code:

Code: Pascal  [Select][+][-]

1. uses ..., BGRAbitmap,BGRADefaultBitmap, BGRABitmapTypes;
2.  
3. const BigImg = 'NE1_HR_LC_SR_W_DR.tif';    // 668 MB
4. var img : TBGRAbitmap;
5. .....
6.  
7. procedure TForm1.Button1Click(Sender: TObject);
8. var startTime : QWord;
9. begin
10.    startTime := GetTickCount64;
11.    Img := TBGRABitMap.Create(BigImg);
12.    showMessage (IntToStr(GetTickCount64 - startTime));
13. end;      
14.  
15.  

Results in an exception:

Code: Text  [Select][+][-]

1. The image reader is not registered for this image format

We had the same problem some years ago.
But I don't know how it was solved.

If bgra uses fcl-image to load (some?) types, add fpreadtiff to your uses clause

In fact BGRA provides its own version BGRAReadTiff, but yes, it is compatible with FPReadTiff.

Thanx marcov and circular!

fpreadtiff did not solve it but BGRAreadTiff did.

2264 milliseconds to load 668 MB tiff from a hard disk

Very good speed!

Cool 

I optimized as I could.
