Region Capture

Region capture is the workhorse of Tex. You draw a rectangle over any part of any monitor, and Tex hands you the pixels inside it.

How to Trigger

SurfaceAction
Global hotkeyCtrl+Shift+S (remappable — see 10.2)
Main toolbarClick the Region button
System trayRight-click the tray icon and pick Region Capture
Dock pillClick the capture button on the floating pill

What the Overlay Does

When you trigger region capture, Tex drops a full-screen CaptureOverlayWindow over every monitor:

  1. The screen dims under a semi-transparent overlay (darkness controlled by Capture.OverlayOpacity).
  2. Instructions at the top read: "Click and drag to select region | ESC to cancel".
  3. Click and hold, then drag to define a rectangle.
  4. While dragging, a live label shows the selection as "W x H pixels" if Capture.ShowDimensions is on.
  5. Release the mouse to confirm. Press ESC at any point to cancel with no capture taken.

After You Confirm

The capture flows through several optional steps, each gated by a setting:

  1. The bitmap loads into the MainWindow preview + inline annotation canvas.
  2. If Capture.OpenEditorAfterCapture is on, the dedicated AnnotationWindow also opens so you can mark up immediately (see 03.1).
  3. If Capture.CopyToClipboard is on, the image is placed on the clipboard as PNG.
  4. If Capture.PlaySound is on, a shutter sound plays.
  5. The capture is appended to history (see 08.5).
SettingDefaultEffect

Capture.DefaultDelay0Pre-capture delay in seconds (see 02.3)
Tip

Tip — If the overlay feels too dark on an HDR monitor, drop Capture.OverlayOpacity to around 30.

Tip

Setting — To skip the annotation editor and keep the main toolbar minimal, turn Capture.OpenEditorAfterCapture off. The capture still lands in the MainWindow preview.
