I am going to use graphviz to generate state flow charts (i.e. blobs representing states, arrows from one blob to another representing events/transtions) based on a transition table.
There are ways to give hints about the preferred placements, in rough terms, through the "rank" specification. That is not defining the placements, just one input parameter to the placement algorithm. Ideally, I would like to give the user a mechanism to drag one or more blobs to a different position, and then redo the layout but with this one blob pinned.
I do not have the time do decipher the placement algorithm from the source code , so now I hope that either someone knows graphviz in great detail, or the placement algorithms: Is pinning of individual graphic elements at all compatible with the placement algorithm? If it is, can this be done in the dot input language to graphviz? Or in some other way?
I am trying to develop a 2D graphics editor on C#.
In that editor I want continuous co-ordinates where ever the mouse hovers.
I tried using Graphics class in C# but it uses the screen co-ordinates.
Instead I want to use world co-ordinates to draw different shapes.
(Some what like a Autocad Editor, but I don't want to include the complex functionalities)
How can I achieve that?
With a lot of hard work. And what do you mean by, "I want to use world co-ordinates to draw different shapes."? It does not matter what co-ordinate system you use, drawing a shape is much the same process.
Sorry can't reply on your question, but highly recommend you to think about 3d, not 2d. With the development of technology, virtual and augmented reality - 2d images are something that might be undemanding soon enough
I really need your help on this topic. I designing some PSD template websites and apps isthisis the right web design or I have to code also? What responsive website means for a web designer is just create the same design for mobile, tablet... or the real meaning of the automatically changing weight for each screen?
And are we able to prototype our web page in Photoshop like the prototyping feature of Adobe XD?
Using OpenTK in devStudio 15 and windows forms on my dell desktop.
When I render a color (eg red = 255, 0, 0, 255), and read the results back it is about, but not quite half of the written value, eg 127, 0, 0, 127.
On a laptop, running the same code, same extremely simple shaders, but different gpu, the red is sometime red on the screen, and sometimes 'half red' and the values I read back are sometimes not exactly half,
Using a framebuffer in opengl instead of Marshalling gives the same results.
All other colors and using r,g,b or any combination gives the same result.
I was planning to use 'designated colors' to identify objects, similar to a shadow map, but the colors are not consistent.
Is this a known or expected behavior? Is it fixable? Running out of things to look for.
Here, there is an article about Creating OpenGL Windows in WPF. But is it possible to embed a pure С++ OpenGL-GLFW or SDL based context into the WForms/WPF, which in its turn will provide controls on the GLFW-context and objects? In other words, WForms/WPF C# editor + C++ GLFW Context.
I am generating a PDF for use in a lasercutter.
The printerdriver for the laser cutter takes vectors with a specific color and stroke-width, and uses them to cut all the way through the material. All rasters/bitmaps are just burnt into the surface of the material.
I would like to be able to take a piece of text and convert it to a vector outline.
I thought this would do it:
I have need to use the Vector2.CatmullRom(...) method in a memory intensive program that currently produces extremely large pictures for testing purposes. I found the ability to do this on the XNA platform. Before adding this reference, I was able to create the pictures I need. Unfortunately, since I now have to compile a 32 bit runtime as that seems to be the only format for the XNA library, I do not have enough memory available to complete the task(s) necessary.
IS there a 64 bit version of this method in this or another library? I need the ability to turn blocky cardinal direction lines into smooth lines with easy slopes (which is why I am using this function).
I'm trying to make a small ASCII block graphics adventure game on Windows using the console terminal, and I am looking for example resources and tutorials on how to make a console window screen wrapper. I mean to change the resolution by changing the fontsize, and then just display simple graphics with ascii block character.
Any free tutorials, examples and resources will be greatly appreciated.
I am writing a fairly simple editor for managing video subtitle information(*). I do not touch the video itself, but use an external player (such as MPC-HC) to video in any of umpteen different formats.
It would be very nice if my editor could obtain the playing time for the video file, to bracket the timing of the subtitles. Some video editors write that into the NTFS attributes, but only sometimes, and only for some formats. I guess some formats provide it in metadata within the file, but again: only for some formats. And I do not want to spend weeks chasing duration info in this format, that format, and the third format...
Do you know of any library that can extract metadata info of this sort from "all" different video file formats? It certainly would not hurt if I could also extract e.g. fps value, video resolution etc.
I would need either source code or something that can be called from dotNet/C# - I am prepared to translate from e.g. plain C to C#. Obviously, I can pick up the source code for MPC-HC and extract that 0.1% of it that I need, but I am hoping for something requiring less work, less need to understand the structure of half a million code lines (or however large MPC source code is).
(*) regarding my desire to reinvent the subtitle editor wheel: I never found any editor suitable for handling multiple subtitle formats, and multiple languages, with the capability to generate a "concrete" subtitle file for lines spoken in specific language, subtitles in a specific languate. Also, I never saw good mechanisms for creating timestamped subtitles from scratch in an efficient manner.
