I want annotation default font size change.

My Implemetation code.

LImageViewerCell* pCreateCell = new JImageViewerCell();
pCreateCell->Create(m_ImageViewer.GetWindowHandle(0), 0);
pCreateCell->EnableAnnotationCreatedCallBack(TRUE);




L_INT JImageViewerCell::AnnotationCreatedCallBack(L_INT nCellIndex, L_INT nSubCellIndex, L_UINT uAnnotationType)
{
UNREFERENCED_PARAMETER(nCellIndex);
switch(uAnnotationType)
{
case ANNOBJECT_RECT:
case ANNOBJECT_ELLIPSE:
case ANNOBJECT_TEXT:
{
HANNOBJECT hAnno;
this->GetAnnotationContainer(nSubCellIndex, &hAnno, 0 );
LAnnText anno(hAnno);
//anno.SetHandle(hAnno);
anno.SetFontSize(50);
}
}

return SUCCESS;
}

The code is not correct. It gets the annotations container then creates a text annotation class from it, which is not a valid approach.

How exactly are you creating the text annotations in the first place? Are you using the mouse to draw them on the cell?

The attached project is a modified from the C++ Medical Viewer demo. This project shows how to set the font size of the text object.

To compile and run the project correctly, copy the project to the following folder:
[LEADTOOLS 17.5 Folder]\Examples\ClassLibrary\MSVC
