I want to draw text on the bottom right of image with ImageEnVect.
How can I measure text width of vector objects ?
When I add text object with commands

int hFooterText = this->ImageEnVector->AddNewObject(true);
this->ImageEnView->ObjKind[hFooterText] = iekTEXT;
this->ImageEnView->ObjFontName[hFooterText] = "Tahoma";
this->ImageEnView->ObjFontHeight[hFooterText] = FontSize;
this->ImageEnView->ObjFontStyles[hFooterText] = fs1;
this->ImageEnView->ObjLeft[hFooterText] = FooterX;
this->ImageEnView->ObjTop[hFooterText] = FooterY;
this->ImageEnView->ObjText[hFooterText] = "This is my footer";

1.How can I set object width to fit with text length.
and how can I measure text width of this object.
2.Is unit of measurement of ImageEnVector->IEBitmap->Canvas the same as vector object,so I can draw text at the bottom right of image correctly.

Thank you.

Hi

You can use ObjTextAutoSize to make the object automatically size to its text:

Then use ObjWidth/ObjHeight to position it.
