Zoom picturebox with static edges (for report)

[projecttoday]

The red does the same thing. It's cut off on the side and the bottom.

This picturebox was actually downsized once earlier. The original was a larger form. I decided to reduce the size of the form and the picture box and because the code multiplies everything by a scaling factor it worked. But the image is too small to see detail. So I decided to add a click to upsize it. The current viewable area of the upsized image looks suspiciously like the size of the old/original picturebox.

In any case it must be a setting somewhere but I can't find it. I am not at all expert in VB.Net drawing code.

The scroll bars are working fine.

Also, the hard copy print works fine.
