NSBitmapImageRep * imgRep = initWithData:] load the defined colorspace data into image rep: NSColor * rgb = [NSColor colorWithDeviceRed:1.0f Tactic #3 - using image and image rep objects: NSImage * image I know I'm drawing a line here, but every little bit helps. Tactic #2 (and I really did not want to try this one as it struck me as cheap and lazy) - NSBezierPath: NSBezierPath * path = What follows are my attempts at drawing some kind of something. Then, load it using a window controller object and ask that for its window. Instead, make a separate NIB for the window. I open the constructing function with: - (void)applicationDidFinishLaunching:(NSNotification *)aNotificationįor a more complex app, it's probably better to not put a window into the Main Menu NIB. This is what's happening in my AppDelegate. I ended up going through more StackOverflow and Apple Kit articles than God can count.ġ) access my blank application window’s “content”Ģ) specify my pixel of interest within that contentģ) access that pixel with its colorspace valuesĤ) rewrite the values directly if possible I really did not want to deal with images and image buffers or draw the smallest visible lines and rectangles, but I was willing to give all that a try.

I want to do this economically, with as few lines of code as humanly possible, because looking at large chunks of code is a real eyesore.

My current objective is pretty simple (at least in the abstract): I want to (re-)color a pixel in my blank Mac OS X application window. To stop drawing at any time, click the Text Mode button on the far left of the Draw tab.Moving forward from phase 1 of my project here: How do I re-define size/origin of app window in code, overriding nib/xib file parameters, with Obj-C, Xcode 11.3.1 on Mac OS X 10.15.2 (Catalina)? To erase any parts of a drawing, tap the Eraser tool, and then drag the eraser over the ink strokes that you want to remove. To select any parts of a drawing, either to modify or move them, click the Lasso Select button, drag a selection around the ink strokes you want, and then Control-click the selection for more options. To erase any parts of a drawing, click the arrow to the right of the Eraser tool, choose the eraser size that you want, and then draw over the ink strokes that you want to erase.

You can make a new selection at any time to begin drawing with a different stroke thickness. Select the stroke thickness for your selected drawing tool by clicking one of the wavy line samples.

To change your custom color selection, click the arrow next to the button again. After selecting a custom color, clicking the Ink Color button will apply that color to any other ink strokes you have selected. Select a custom color by clicking the arrow next to the Ink Color button and choosing the exact color you want to use. Select a basic drawing color by clicking one of the four color dots There’s a Pen, a Marker, and a Highlighter.Īfter you’ve chosen your preferred drawing tool, customize your drawing style by doing any of the following:
