Hi,
I have a TImageEnMview thumbnail to load images.
When I selected a image on thumbnail, I edit it using a TImageEnVect.
Since I use vectorial object, I canīt save this image with vectorial objects back to thumbnail unless I use ImageEnVect1.CopyObjectsToBack.
The problem is that doing it, my vectorial objects are lost. Next, when I selected other thumbnail image and back to thge first I have no way to recover my vectorial objects.
Is there a workaround to do it?
Regards,
Luiz

Hi,
Thank you so much,
Your help was great appreciated in this topic.
I have a basic dicom viewer working now.

This is an application specific question (put a button "Save", "Cancel") or just save the image when TImageEnMView has another image selected (look helps for a events list). |

Hi,
You were correct. It works well with Wang Annotations. I thought that I had to delete this line to substitute with your tip:
ImageEnMView1.CopyToIEBitmap( idx, ImageEnVect1.IEBitmap );
I put this line again and all works ok.
But, what event from TImageEnMView thumbnail should I use to save changes to current image, before I select a new image on thumbnail.

of course, DICOM images cannot embed Wang annotations.

TImageEnMView handles multiple images while TImageEnVect handles a single image and annotations over it.
You could load/save vectorial objects, for each dicom frame, in separated files using LoadFromFileIEV and SaveToFileIEV. |

Hi,
It seems it doesn't work with dicom image. The bitmap image in TImageEnVect disappears.
If I use the next, no image is showing:
ImageEnMView1.MIO.Params[idx].ImagingAnnot.CopyToTImageEnVect( ImageEnVect1 );
ImageEnVect1.Update();
If we had a TimageEnMview derived from TImageEnVect, maybe the problem was solved.

Hi,
supposing you have to stay compatible with Wang annotations (which is a subset of objects and properties supported by ImageEn), you can transfer objects from TImageEnVect to TImageEnMView writing:
ImageEnMView.MIO.Params[imageIndex].ImagingAnnot.CopyFromTImageEnVect( ImageEnVect1 );
The opposite (from TImageEnMView to TImageEnVect) is:
ImageEnMView.MIO.Params[imageIndex].ImagingAnnot.CopyToTImageEnVect( ImageEnVect1 );
ImageEnVect1.Update();
This way (Wang annotations) allows you to embed objects inside multipage TIFF image files and be compatible with Windows preview, but allows a subset of supported vectorial objects.
Other ways (ie saving/loading vectorial objects in a separated file, for each page) allows you to use all objects and related properties.
