Hello,
i am very new on ImageEn. I saw in some sample applications the different selection modes (for example rectangle or circle).
If i use the rectangle mode i can edit the selection with the mouse.
I hope same is possible for polygon selections. This means i can select the nodes and move them of an poligonal selection.
Thanks alot for reply
Kind regards.
Markus

Hi
ImageEn does not support free form manipulation, so if you have an ellipse object, for example, you can only stretch it to make it higher/flatter, you cannot change it to a completely different shape, such as rounded square.
If you have a polygon object, you can drag the points of the polygon to change it to any shape, however.
See the Annotations demo for an example.

Hello Mr. Miller,
i played around with the demo. Thanks for your great tip.
I set the ObjPolylineClosed poperty to true --> so i can set the brushcolor for filling the area of my polygon.
Then i use copyObjectsToBack and save the file with io.SaveToFile('xxx.bmp');
I can live with that.
Thank you very much for your great help

Yes, you can color the border as well as the background, but not by painting... you have to set object properties. Look at the Vectorial demo in samples folder.

i have to test this, but if i understand correctly i can create only the border and set the color for this? I can not fill the area with an specific color?

With ImageEnVect you do not fill the color, you specify the objects brush color... Other than that it should work well I suspect.

Dear Mr. Miller.
Thanks for your reply.
I do not need necessarily a selection. If i can create a Polygon with ImageEnVect,
modify the nodes and fill the polygon area with a color and "add" the polygon to the image (saved as bmp or jpg) this can a solution for me.
Kind regards
Markus

I failed to mention that if you use ImageEnVect you can draw polygons and edit the nodes as well... but the ImageEnVect object is not a selection.

If there is a selection all ImageEnProc will effect only the selection. If there is no selection the procedure effects the entire bitmap. So... if you fill with a color only the selected area will be filled:
ImageEnView1.Proc.Fill(CreateRGB(127,50,200));
ImageEnView1.Proc.Fill(clBlack);
You can not edit the nodes of the polygon selected area; however. It is just not possible with ImageEn.

Thanks for your reply.
Perhaps there is another solution.
Background: I have to fill the selected or drawed polygon area with a fill-color.
Is there any way to draw a polygon (with editable nodes) and fill this area with an color?
Thanks a lot for all tips and answers.

Unfortunately, ImageEn does not support moveing the points of a selection polygon like you can with a rectangle.
