I am wondering whether it is easy to setup a coordinate system for
drawing (using GDI+) that uses meters (or any custom scaling for that
matter). Currently, I need to convert from pixels to meters for
scaling. This can sometimes get rather complex when you need to take
scaling into account or other things like window resizing, scrolling,
etc.
There is a property called PageUnit which can be set to World. I could
not find any examples...

The main ideea:
I havea 513x513 array of values....I draw a sort of map using that values
for colors... so I have a realistic lanscape (map).
I want to zoom about 60 times that map...and the zoomed area to be drawn on
full screen.
I want to draw it smoth not a square of 60 pixels x 60 pixels
with one color, because I can see blocks and it's not good.
There is a way to interpoate the colors between rectangles to show a smoth
zoom?

Hi,
I'm trying to create a little program that loads a 1bpp bitmap
(black/white) and displays it in a PictureBox using the PictureBox's
Paint event. I have buttons for zooming in/out and I calculate the
source image origin rectangle and the destination rectangle.
Problem is that the image should look "blocky" when I zoom in,
but instead it looks *very* anti-aliased.

Hi
I was looking for a component that will enable me to zoom into an image very
easily and quickly. I was hoping there may be something, perhaps part of
VB.NET, that will allow me to drag a box over a selected area and this would
then be displayed at full screen.
Any help on this would be greatly appreciated.
Kind regards, Carl Gilbert

Dear all,
I need a picturebox on which I can with GDI+ draw rectangles. The scroll and
zoom should be supported. Do I have to manually resize rectangles,when zoom
button clicked and change position when scroll done and redraw with new
coordinates? Is there some standard procedure for that? Any link or advice
is greatly appreciated.
Thanks,
Boni

Hi,
I've got a Picturebox, into which I am putting a frame bitmap from a video
camera. The camera bitmap is larger than the picturebox, which has SizeMode
set to "Zoom" which causes the bitmap to be resized and correctly displayed.
My question is whether letting the Picturebox do the bitmap resizing is the
most efficient mechanism, or whether it would be preferable to perfrom the
resizing myself before passing the modified image to...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
