\nhttp://www.barberdsp.com/downloads/Dayton%20Paper.pdf\n\n### Image\n\nTo load an image:\n* tap **\"Take Picture\"** or **\"Pick Picture\"** menu button, or \n* use the **Share** option of an app like e.g. Gallery.\n\nTo keep the aspect ratio, black borders will be added if necessary. \nOriginal image can be resend using another mode without reloading. \nAfter image rotation or mode changing the image will be scaled to that mode's native size. \nAfter closing the app the loaded image will not be stored.\n\n### Text Overlay\n\nActions for working with text overlays:\n* Single tap **to add** a text overlay. \n* Single tap on text overlay **to edit** it. \n* Long press **to move** text overlay. \n* Remove the text **to remove** a text overlay.\n\nAfter closing the app all text overlays will be stored and reloaded when restarting.\n\n### Menu\n\nAvailable menu options:\n* **\"Play\"**: Sends the image\n* **\"Stop\"**: Stops the current sending and empties the queue\n* **\"Pick Picture\"**: Opens an image viewer app to select a picture\n* **\"Take Picture\"**: Starts a camera app to take a picture\n* **\"Save as WAVE File\"**: Creates a wave file in the Music folder in SSTV Encoder album\n* **\"Transform Image\"**:\n * **\"Rotate\"**: Rotates the image by 90 degrees\n * **\"Reset\"**: Resets image rotation and scaling\n* **\"Modes\"**: Lists all supported modes\n\n### Installation\n\nThe working app \"SSTV Encoder\" can be installed \n\non Google Play: \nhttps://play.google.com/store/apps/details?id=om.sstvencoder\n\nor on F-Droid:

Modes

\n\nSupported SSTV modes:\n
    \n
  • Martin Modes: Martin 1, Martin 2
    • \n
  • PD Modes: PD 50, PD 90, PD 120, PD 160, PD 180, PD 240, PD 290
    • \n
  • Robot Modes: Robot 36 Color, Robot 72 Color
    • \n
  • Scottie Modes: Scottie 1, Scottie 2, Scottie DX
    • \n
  • Wraase Modes: Wraase SC2 180
    • \n
\nThe mode specifications are taken from the Dayton Paper, JL Barber, \"Proposal for SSTV Mode Specifications\", 2000:
\nhttp://www.barberdsp.com/downloads/Dayton%20Paper.pdf\n\n

Image

\n\nTo load an image:\n
    \n
  • tap \"Take Picture\" or \"Pick Picture\" menu button, or\n
  • use the Share option of an app like e.g. Gallery.\n
\nTo keep the aspect ratio, black borders will be added if necessary.
\nOriginal image can be resend using another mode without reloading.
\nAfter image rotation or mode changing the image will be scaled to that mode's native size.
\nAfter closing the app the loaded image will not be stored.\n\n

Text Overlay

\n\nActions for working with text overlays:\n
    \n
  • Single tap to add a text overlay.
    • \n
  • Single tap on text overlay to edit it.
    • \n
  • Long press to move text overlay.
    • \n
  • Remove the text to remove a text overlay.
    • \n
\nAfter closing the app all text overlays will be stored and reloaded when restarting.\n\n

Menu

\n\nAvailable menu options:\n
    \n
  • \"Play\": Sends the image
    • \n
  • \"Stop\": Stops the current sending and empties the queue
    • \n
  • \"Pick Picture\": Opens an image viewer app to select a picture
    • \n
  • \"Take Picture\": Starts a camera app to take a picture
    • \n
  • \"Save as WAVE File\": Creates a wave file in the Music folder in SSTV Encoder album
    • \n
  • \"Transform Image\":
    • \n
      \n
    • \"Rotate\": Rotates the image by 90 degrees
      • \n
    • \"Reset\": Resets image rotation and scaling
      • \n
    \n
  • \"Modes\": Lists all supported modes
    • \n
