  • Drawing scaled emoji icons on iOS

    - by Eimantas
    I'm trying to implement my own emoji icon keyboard and have some problems. I'm trying to draw emoji icons at the same size as on native iOS emoji keyboard, but when doing simple drawing (standard unicode characters like "\ue415") icons always appear at original size. When trying to increase the font - emoji icons stay of the same size. When applying CGAffineTransform for scaling - drawn icons are bigger, but pixelated and blurred. How should I go about drawing emoji icons bigger, but sharper?

  • "Beveled" Shapes in Quartz 2D

    - by Shaggy Frog
    I'm familiar with some of the basics of Quartz 2D drawing, like drawing basic shapes and gradients and so on, but I'm not sure how to draw a shape with a "beveled" look, like this: Essentially we've got a shine on one corner, and maybe some shading in the opposite corner. I think -- I didn't make this image, although I'd like to be able to approximate it. Any ideas? This is on the iPhone, and I'd like to use built-in frameworks and avoid any external libraries if at all possible.

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

  • Visual Studio 2008 Report Designer - can't turn on gridlines

    - by bob
    Microsoft in their infinite wisdom have seen fit to remove the useful "Draw Grid" and "Snap to Grid" checkboxes in the report properties dialog that were in VS 2005 but are not in VS 2008. I'm assuming they put that functionality elsewhere but I can't find it after going through what seems like every menu option available. Does anybody know how to turn on the gridlines?

  • Plotting Scientific data in .net

    - by Dan Schubel
    Does anyone have any recommendations for plotting scientific data in .net (c# winforms). Some of my requirements are: real time plotting, 3D (waterfall), multiple axis, ability to accept BindingList as a data source and recognize any changes to the data. I also need a high level of user interactivity such as the ability to graphically select 1 or more series, draw regions. highlight part of a series, etc. So far I've looked at Nevron, Synchfusion, Infragistics, TeeChart and a few others.

  • Java MS Word-like Application

    - by Halo
    You know in MS Word, you can write text and draw&put shapes anywhere you want.. in the text when you hit enter and get to a new line, the shapes below your cursor also moves down one line? I want to implement that property in Java on a pane, using components as the shapes and text. How can I provide absolute positioning for shapes but at the same time preserve the space between them? I'll appreciate any idea, cause I'm almost out of ideas.
