Drawing is done simply by hold down mouse left button and drag it across the canvas. Our Paint supports Wacom and Surface ipts pressure sensitive pen input (including tilt). If you closed the canvas panel accidentally, go practice the user interface manipulation as mentioned previously, and open a new one.
Check if you actually selected "Paint" mode in the tool panel (or on the application header), also make sure you have a layer and brush selected. (If you haven't deleted them, there should already be a selected layer and brush)
Drag the "◿" symbol on the color picker to adjust its size.
Press and hold middle mouse button to move the canvas, press and hold Ctrl+Middle mouse to zoom, press right mouse betton or Ctrl+Right mouse to pick up color from the canvas.

Select "Cropping" tool to adjust the final cropping of the canvas. By default cropping is disabled, click "Show Border" to enable it. You can drag and move the cropped region. Drag your mouse pointer outside the cropping region to adjust border position or size.
Our Paint stores all image content completely on your video memory. Please take a moment to estimate the memory cost if you need to draw/paint a huge painting. For integrated graphics, modern day Intel integrated graphics should be able to access up to half of the entire memory of your machine. Otherwise some machines also support setting VRAM limit inside BIOS. Our Paint uses 16bit, 1024px sized texture tiles to form a complete canvas, thus a painting of around ~1000px in size would roughly take 8MB~32MB of video memory.
Our Paint has a simple layer system. You could add, remove laerys as well as adjusting blending mode and transparency. Layers are not movable in current version, also it only supports "Normal" and "add" blending modes. Drag the "☰" symbol to the left of the layer name to reorder layers. Click "🠳" to merge the current layer with the one below it.
You can adjust the background color of the canvas. When you started painting, the background color is locked to prevent accidental changes. To adjust it again, click "Locked" button, then it's unlocked.
You can set the color profile of the entire canvas in the layers panel, it's recommended to keep it in "sRGB" most of the time.
To save the canvas, use File→Save. If you haven't assigned a file for it, Our Paint will open a dialog. Click the drop down menu to the right side of the Main Canvas entry, select "< Save as a new file >", then specify a file in the file dialog. Our Paint allows 3 file extensions for saving data: "udf", "ourpaint", "ourbrush". You can choose either one, but to visually identify a canvas file, it's recommended to use "ourpaint". When you are done selecting the file, click the "Save all modified" button to the lower right corner of the dialog to save stuff.
Use File→Read to read any data file.
Unsaved data block would have a "🌑" icon showing to the left of their names. Our Paint will always open the saving dialog when you close the program if there's any unsaved data block or unassigned ones.
You could save brushes to the same file with the canvas, and if you open that file, those brushes will be loaded as well.
