ZoomMe

Application for zooming/magnifying and annotating the desktop (like ZoomIt under windows).

You can...

  • Draw lines, rectangles, arrows, ellipses and hand draws (free forms)!
  • Insert text
  • Highlight parts of the screen with colors (a highlighter)
  • Use a "Flashlight" function to concentrate attention on the cursor position
  • Zoom in and out of the desktop.
  • Switch between your desktop and a blackboard
  • Save the current work to an image
  • Record what you do
  • Save the current work in a .zoomme file and recover from it later (like a project/backup file)

Made with Qt6 (it works with Qt5 too. There's an older branch for that) and OpenGL.

Demonstration of the functionality

The idea of the Flashlight effect was taken from tsoding/boomer

Functions & Mappings

Essential

Key/Event Function
Press & Hold Control This will show a panel with all the available tools, allowing you to interact with the app without the need to remember all the key mappings, except for the essentials ones.
Mouse Wheel To zoom in and zoom out
Shift When it's zoomed in, if you press and hold the key, the screen will not follow the mouse, so you can freely move it around in that part of the screen (for drawing, for example). When you release it, it will continue following the mouse
Shift + Mouse Wheel When the flashlight effect is turn on, this will increase/decrease the size of the "light"
Right Mouse Button When the mouse tracking is disabled, you can drag the canvas around
ESC The function of the Escape key is described in here...

Escape key functions

The Escape key performs the following actions in a sequential order. If one condition applies, it executes only that function.

  1. If you are writing text, it finishes writing text.
  2. If you are inside a mode (pick a color, delete a drawing, trim or the flashlight effect), it exits that mode
  3. If you are in 'hide all' mode, it restores to 'show all'
  4. If you are zoomed in, it restores the zoom
  5. If you are recording, it stops recording
  6. Otherwise, it quits/exits the app

Text Mode Mappings

Key Function
Enter To finish writing text
Shift+Enter To make a new line when writing text
Left/Right keys To go to the previous/next character when writing text
Up/Down keys To go to the previous/next line break when writing text
Click a text You can access and modify the text by clicking on it when you're in text mode. However, you cannot be writing or drawing a new text while clicking

Non-essential

Export

Key/Event Function
S Save the current work to an image, which will be stored in the Desktop folder (or the current path if not found). The computer will beep if the image was correctly saved
Shift + S Save the current work to the clipboard. The computer will beep once the mapping is pressed
Shift + E Save the current work inside a '.zoomme' file, so you can later restore the state of the program from it. It is going to be save in the same path and with the same name that the image of the screenshot. The computer will beep if the file was correctly saved
- (dash) Start/stop recording. After stopping, a video will be produced, but it may take some time for rendering (You'll know when it finished rendering when the recording indicator of the status bar goes away and you listen a beep). The video is going to be save in the same path and with the same name that the image of the screenshot. Requirements: have ffmpeg installed, and use a Unix based system

General

Key/Event Function
. (period) To toggle the "Flashlight effect" on the cursor.
Tab To toggle between your screen and a blackboard mode. By the way, your drawings will persist between the modes
Space To toggle the visibility of the elements of the screen: hide the status bar, hide all or show all

Available Drawing Modes

Key Function
Z To change the mode to drawing Lines (mode by default)
X To change the mode to drawing Rectangles
E To change the mode to drawing Ellipses
F To change the mode to drawing Free forms / Hand draws
T To change the mode to insert Text
H To highlight the background of the forms/drawings
A To draw an arrow at the end of the line

Available Actions for the drawing modes

Key Function
U To delete the last drawing of the current draw mode (undo)
Shift + R To redo the last deleted drawing of the current draw mode (redo)
, To delete a drawing (from the current mode) with the mouse. You can exit by deleting a form, with the Escape key or pressing , again
Q To clear all the drawings

Running (flags)

Warning

When using Wayland, this program is unable to take a screenshot, so it must be run with either the -l flag for a transparent background or th -i flag for grabbing an image

  • [ --help ] Show the help message
./zoomme --help

Synopsis

./zoomme {configurations} {mode}

Configuration

./zoomme {[-p path/to/folder] [-n name_of_file] [-e:i jpg] [-e:v gif]} {mode}
  • [ -p ] Set the path where the produced files will be saved

    • It can be an absolute or relative path
    • By default, ZoomMe saves it to the Desktop folder
  • [ -n ] Set the name of the produced files

    • By default, the name will be: Zoomme dd-mm-yyyy hh.mm.ss. The format of the date can be customized in the zoomwidget.hpp file
  • [ -e:i ] Set the extension of the exported image (when pressing the 's' key)

    • By default, the extension will be: png
  • [ -e:v ] Set the extension of the recorded video (when pressing the '-' key)

    • By default, the extension will be: mp4

Modes

[ -l ] Use a transparent background. No zooming allowed, only drawing

./zoomme {configurations} {-l}

[ -i ] Use an image as the background (instead of the desktop)

You can modifying any image (including previously saved images from ZoomMe)

./zoomme {configurations} {-i path/to/image [-w|h] [--replace-on-save]}
Additional arguments:
  • You can force the image to fit the screen's width or height with -w or -h after providing the image path, like this: ./zoomme -i path/to/image -w, if you do not providing anything, it automatically detects the best option.

  • You can overwrite the image provided when saving by doing this: ./zoomme -i path/to/image --replace-on-save. This will autocomplete the -p, -n and -e:i arguments for you. How kind :)

[ -r ] Restore the state of the program from a `.zoomme` file

Load/Restore the state of the program saved in that file. It should be a .zoomme file.

Ensure that you execute the file on the same monitor where it was previously run, or ensure that both monitors have the same resolution for optimum results. Otherwise, if the resolutions (between the saved one and the actual monitor) differ, the image (including the drawings) will be scaled, and while it will still work, the image may lose quality

This will override the file name, video extension and image extension configuration for exporting files with the saved one. You can still change the save path, as it's not saved in the .zoomme file

./zoomme {configurations} {-r path/to/file.zoomme [-w|h]}
Additional arguments:
  • If the resolutions differ, you can force the image to fit the screen's width or height with -w or -h after providing the image path, like this: ./zoomme -r path/to/file.zoomme -w, if you do not providing anything, it automatically detects the best option.

[ -c ] Use an image from the clipboard as the background (instead of the desktop)

You can use any image from the clipboard as the background

./zoomme {configurations} {-c [-w|h]}
Additional arguments:
  • You can force the image to fit the screen's width or height with -w or -h, like this: ./zoomme -c -w, if you do not providing anything, it automatically detects the best option.

[ --empty ] Create an empty blackboard

You can create an empty blackboard with the given size.

./zoomme {configurations} {--empty [width] [height]}

To do

  • Make ffmpeg processing in a separate thread
    • Notify the user that ffmpeg is running in the background
    • Prevent the user from recording again untill ffmpeg finished (although they can use other parts of the app normally)
  • Rewrite and reorganize the header file (it's currently quite messy)

:suspect: Secret :suspect:

Shhh! Don't tell anybody... 🤐

You can customize certain features in the app 🎨 by editing the header file (zoomwidget.hpp). Within this file, there are macros that determine various program behaviors. You can modify the content of these macros located inside the "Customization" comment section. To apply the changes you've made, simply recompile the program.

The customizable elements are:

  • Color codes for the color of the drawings
  • The font size (increase/decrease the size factor, when the default font size is too small or too big)
  • The date format when saving screenshots, recordings and .zoomme files
  • Icons in the status bar
  • FPS and quality of the recording
  • Default folder for exporting files
  • And more!
