Build A Photoshop Like App With TKinter and Python GUI Apps

Learn to draw a straight line on a Tkinter canvas with create_line, using coordinates x1,y1,x2,y2 and a red color, and understand the canvas coordinate system.

Draw with the mouse by painting on the canvas, using the paint function to track mouse motion, set color and brush size, and apply smoothing.

Define brush parameters for a Tkinter photoshop-like app to adjust size, color, and brush type; implement cap styles - round, projecting (diamond), and slash - and plan runtime updates.

Create a brush size label that updates as the Tkinter slider moves, convert the slider value to an integer, and apply it to the canvas drawing in the paint function.

Use the color chooser to update brush and canvas colors by selecting a hex color returned by the color chooser, using a global brush color with a black default.

Implement a clear screen function for the canvas by calling canvas.delete to remove all items, then reset the canvas background color to white for quick redraws.

Create a save as dialog with tkinter's filedialog to prompt for a file name and location. Initialize it in the paint/images directory and filter to PMG files (star dot PMG).

Implement a python tkinter logic to ensure saved images have the correct png extension. Check the filename ends with .png and append it if missing, via a simple if statement.

Convert your Python program into a standalone exe using a packaging tool, producing a single file for Windows, Linux, and Mac with a dist folder.
