I am unable to call ImageEnVect1.CreatePolygonsFromSelection to create a polygon object since it keeps giving me a "out of memory" error. Is there an alternative to create a polygon object from a selection?
Thanks in advance.
Andy

Hi Andy
What version are you using? Can you give us the steps to reproduce this issue?

Hello Nigel, I am using the latest version 6.2.2. I just set the MouseInteract to allow making a Polygon selection and when it is closed, I called CreatePolygonsFromSelection.
ImageEnVect1.MouseInteract := [miSelectPolygon];
ImageEnVect1.CreatePolygonsFromSelection;
If I make a small selection, the error does not happen. Is there a way to get around this? I am not allowed to resize the whole image to a smaller size.
Thanks Nigel.
Andy

Hi Andy
I cannot reproduce that even with highly complex selections.
Is there any more information you can give me?

Hi Nigel, thanks for checking this for me. It seems to happen when my file is a TIF file. I converted it to a JPG which reduces its size dramatically and the error disappears. But the TIF file definitely gives the error.
I am trying to make a selection around each label image in the TIF file and convert the selection to a polygon object.

Thanks Nigel. I hope you can reproduce this on your end.

Hi Andy,
I've tried with my prog. (built with Ien 5.2.0) and yes, it crashes when four selections are marked (using shift key). I'm converting selections into vector polygons and draw strokes through polygon points. Here is Eurekalog screen (if it can be of any help):

Thanks very much Spetric. I am doing the same functions too. I hope there is a fix for this.

Hi Andy
Tested that TIFF and still had no failure. What version of Delphi are you on?

Hi Nigel, I am using Delphi Seattle 10 with the latest ImageEn 6.2.2, although I have similar results with XE6 Update 1 as well.

Hi,
I've tried with C++ XE5 32-bit and Ien 6.2.2 and the error "out of memory" is thrown in CreatePolygonsFromSelection method.
I've used lasso selection and selected four labels (roughly).
This is selection scenario that produces error:

Thank you spetric and Nigel. I have also encountered "Floating point error" when calling CopySelectionToBitmap after making the polygon selection with the same file. I think the issue could be related.

Hi
We have an update to improve the memory handling (though still not fast with very large selections). Email us if you want the updated source.

Hi Nigel, thanks for the updated code. Unfortunately, I am still getting the error. I created a polygon object using the same image file by manually drawing it. I then save it to .iev file. I would load it back and do the following:
if (ImageEnVect1.ObjKind[0] = IEKPolyLine) or (ImageEnVect1.ObjKind[0] = IEKEllipse) then begin
for x:=0 to ImageEnVect1.ObjPolylinePointsCount[0]-1 do
ImageEnVect1.AddSelPoint( ImageEnVect1.ObjPolylinePoints[0, x].x, ImageEnVect1.ObjPolylinePoints[0, x].y );
ImageEnVect1.EndSelect();
end;
ImageEnVect1.RemoveAllObjects;
ImageEnVect1.Update;
Bmp := TBitmap.Create;
try
ImageEnVect1.CopySelectionToBitmap( Bmp, True );
FTempVect.Bitmap.Assign( Bmp );
FTempVect.Update;
FTempVect.IO.SaveToFileBMP( fsc ); <--- Error (Floating point)
finally
Bmp.Free;
end;
I get a floating point error. This code works with smaller files or smaller selection but not with this file for some reason.
Can you verify if you can reproduce this error?
Thanks again.
Andy

I did a test where I created a rectangle object instead of a polygon and it also seems to fail. There is no error but it appears to hang:
if (ImageEnVect1.ObjKind[0] = IEKBOX) then begin
x1:=ImageEnVect1.ObjLeft[0];
y1:=ImageEnVect1.ObjTop[0];
x2:=(ImageEnVect1.ObjWidth[0]+ImageEnVect1.ObjLeft[0]);
y2:=(ImageEnVect1.ObjHeight[0]+ImageEnVect1.ObjTop[0]);
ImageEnVect1.Select( x1, y1, x2, y2, iespReplace );
end;
It looks like the issue is the CopySelectionToBitmap for all cases, at least with my sample file.

I assume you are compiling with Win32 platform. Try compiling with Win64 platform and see if the error still occurs.

Hi Bill, yes I am compiling with Win32 because I don't have a choice. The other libraries that are in the application are not 64-bit compliant...yet. So, I am in a bind...

Hi Andy
Your first bit of code is wrong. You can't use ImageEnVect1.ObjKind[ 0 ], because TImageEnVect objects are not indexed, but listed by hObj, so you must call:
ihobj := ImageEnVect1.GetObjFromIndex( 0 );
if (ImageEnVect1.ObjKind[ ihobj ] = IEKPolyLine) or (ImageEnVect1.ObjKind[ ihobj ] = IEKEllipse) then
begin
for x:=0 to ImageEnVect1.ObjPolylinePointsCount[ ihobj ]-1 do
ImageEnVect1.AddSelPoint( ImageEnVect1.ObjPolylinePoints[ ihobj, x ].x, ImageEnVect1.ObjPolylinePoints[ ihobj, x ].y );
ImageEnVect1.EndSelect();
end;
Also, what is the purpose of FTempVect? If it is just for saving your BMP, then you can just make BMP a TIEBitmap and call BMP.write( fsc );

Hi Nigel, GetObjFromIndex helped to get his solved. Thanks very much for solving this very nagging issue for a while now.
