Dst... example for C++ 5.0 and later

This example uses the destination rectangle properties to zoom in on an image.

// Calculate the values to zoom in by 10 percent and center the image.
m_LEADRasterView1.SetDstWidth(m_LEADRasterView1.GetDstWidth() * 1.1f);
m_LEADRasterView1.SetDstHeight(m_LEADRasterView1.GetDstHeight() * 1.1f);
m_LEADRasterView1.SetDstTop((m_LEADRasterView1.GetScaleHeight() - m_LEADRasterView1.GetDstHeight()) / 2);
m_LEADRasterView1.SetDstLeft((m_LEADRasterView1.GetScaleWidth() - m_LEADRasterView1.GetDstWidth()) / 2);
// Set the clipping area to the same as the destination rectangle
m_LEADRasterView1.SetDstClipWidth(m_LEADRasterView1.GetDstWidth());
m_LEADRasterView1.SetDstClipHeight(m_LEADRasterView1.GetDstHeight());
m_LEADRasterView1.SetDstClipTop(m_LEADRasterView1.GetDstTop());
m_LEADRasterView1.SetDstClipLeft(m_LEADRasterView1.GetDstLeft());
// Redisplay the image
m_LEADRasterView1.ForceRepaint();
