We are using build 4.1.2 beta with Delphi XE
We use the ImageEnMView component which load a 45 page tiff via
ImageEnMView.LoadFromFileOnDemand(). the exception happens when executing ImageEnMView.MIO.SaveToFileTIFF(_Currentfile),see below. After the exception the ImageEnMView image 1-5 are blank.
if the number of pages is small, say 10 pages there are no issues.
Thanks All...
Ron
procedure TImagEnFrm.ImageAutoCollate(iList:TList<integer>);
var
PagesToMove: Int32;
i: Int32;
MoveTo, PageToMove: Integer;
ImageEnVectTemp: TImageEnVect;
begin
if iList.Count > 0 then begin
ImageEnVectTemp := TImageEnVect.Create(nil);
iList.Sort;
ImageEnMView.LockPaint;
PagesToMove := (iList.Count div 2)-1;
try
for i := 1 to PagesToMove do begin
PageToMove := iList[Pred(iList.Count)] ;
MoveTo := iList[Pred( i*2 )];
ImageEnMView.MoveImage(PageToMove ,MoveTo);
ImageEnMView.UpdateEx(true);
// need this to load file into viewer for update
ImageEnMView.CopyToIEBitmap(PageToMove, ImageEnVectTemp.IEBitmap);
ImageEnMView.CopyToIEBitmap(MoveTo, ImageEnVectTemp.IEBitmap);
end;
ImageEnMView.MIO.SaveToFileTIFF(_Currentfile);
finally
ImageEnMView.UnLockPaint;
ImageEnVectTemp.Free;
end;
end;
end;

Hi Ron,
because LoadFromFileOnDemand uses threads to load images (when they are actually displayed) please make sure that your code access to an image when it is actually loaded.
Also, please describe what your code should do, another solution (using other ImageEn functions) could be more efficient. |

Hi Ron
Can you give me a simple way to reproduce this without using generics?

After further test we see that this issues is raised when performing any operation when the document is more than 38 pages. |

One addtional note. The problem seems to be raised when there are more than 38 pages and you try to collate all or just a subset of pages.
Thanks

its seems that a tif file can not be uploaded so I posted them to our site.
www.docuxplorer.com/download/testdocuments.zip
As part of the test we would select the last 6 pages of the document to be collated.
Thanks
Ron
P.S. Let me know when you have the file so we can remove it from oursite. |
