  • How to convert any text/font to its bezier path representation?

    - by yizzreel
    I have a bezier path library to draw complex bezier paths without problem. Now, I need to know how to read a text or font and extract its path information to draw it as a path instead of as text. I came across a C applicaiton, FontForge. It does exactly what I need, picks any font and extract its path information. But what I need to know is how it does it to add that feature to my drawing library.

  • Which JavaScript graphics library has the best performance?

    - by DNS
    I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority. The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one. Has anyone done a performance comparison between any of these?

  • How can I calculate a trend line in PHP?

    - by Stephen
    So I've read the two related questions for calculating a trend line for a graph, but I'm still lost. I have an array of xy coordinates, and I want to come up with another array of xy coordinates (can be fewer coordinates) that represent a logarithmic trend line using PHP. I'm passing these arrays to javascript to plot graphs on the client side.

  • Is there a good NumPy clone for Jython?

    - by jbrogdon
    I'm a relatively new convert to Python. I've written some code to grab/graph data from various sources to automate some weekly reports and forecasts. I've been intrigued by the Jython concept, and would like to port some Python code that I've written to Jython. In order to do this quickly, I need a NumPy clone for Jython (or Java). Is there anything like this out there?

  • GDI+: Set all pixels to given color

    - by Charles
    What is the best way to set the RGB components of every pixel in a System.Drawing.Bitmap to a single, solid color? If possible, I'd like to avoid manually looping through each pixel to do this. Note: I want to keep the same alpha component from the original bitmap. I only want to change the RGB values. I looked into using a ColorMatrix or ColorMap, but I couldn't find any way to set all pixels to a specific given color with either approach.

  • Controlling the print options of a pdf

    - by John Nolan
    I am producing a number of PDFs using either SSRS or using an HTML to PDF component. What I want to do for each document is to set the first page to print to tray 1 and subsequent pages. Is there anyway to do this? System.Drawing.Printing and System.Printing seem like good candidates but they don't seem to be useful for PDFs (i may be wrong). The Adobe sdk doesn't at first glance seem to have that level of granularity either.

  • Error:A generic error occurred in GDI+

    - by sanfra1983
    Hi, I created a web project on the server, and when I upload an image shows me the error Error: A generic error occurred in GDI +. I have read many links on the net that talk about this issue, and although I made the changes, nothing went wrong. I was thinking if the case is not an issue of permissions to folders. In fact I have two folders one inside the other. This is the code to resize the image: public Bitmaps ResizeImage (Stream stream, int? width, int? height) ( System.Drawing.Bitmap bmpOut = null; const int defaultWidth = 800; const int defaultHeight = 600; int width = lnWidth == null? defaultWidth: (int) width; int height = lnHeight == null? defaultHeight: (int) height; try ( LoBMP bitmap = new Bitmap (stream); ImageFormat loFormat = loBMP.RawFormat; decimal lnRatio; lnNewWidth int = 0; lnNewHeight int = 0; if (loBMP.Width <& & lnWidth loBMP.Height <lnHeight) ( loBMP return; ) if (loBMP.Width> loBMP.Height) ( lnRatio = (decimal) lnWidth / loBMP.Width; lnNewWidth = lnWidth; decimal = lnTemp loBMP.Height lnRatio *; lnNewHeight = (int) lnTemp; ) else ( lnRatio = (decimal) lnHeight / loBMP.Height; lnNewHeight = lnHeight; decimal = lnTemp loBMP.Width lnRatio *; lnNewWidth = (int) lnTemp; ) bmpOut = new Bitmap (lnNewWidth, lnNewHeight); Graphics g = Graphics.FromImage (bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.FillRectangle (Brushes.White, 0, 0, lnNewWidth, lnNewHeight); g.DrawImage (loBMP, 0, 0, lnNewWidth, lnNewHeight); loBMP.Dispose (); ) catch ( return null; ) bmpOut return; ) and this is the code that I insert in the codebehind: string filepath = AppDomain.CurrentDomain.BaseDirectory + img_veterinario / "; string = filepathM AppDomain.CurrentDomain.BaseDirectory + img_veterinario / img_veterinarioM; Reseize Reseize R = new (); Bitmap = photosFileOriginal r.ResizeImage (fucasiclinici.PostedFile.InputStream, 400, 400); Bitmap = photosFileMiniatura r.ResizeImage (fucasiclinici.PostedFile.InputStream, 72, 72); String filename = Path.GetFileName (fucasiclinici.PostedFile.FileName); photosFileOriginal.Save (Path.Combine (filepath, filename)); photosFileMiniatura.Save (Path.Combine (filepathM, filename)); Can you help me? Thanks

  • Canvas and HTML5: Supported Browsers?

    - by Paddy
    I am looking at using HTML5 Canvas element for my upcoming project. I want to know what all major browsers (including the versions!, cos i know that the latest builds do support canvas) support the Canvas tag. I don't give a damn about IE. So don't bother reporting IE. :) In this tutorial Drawing shapes - MDC, the quadraticCurveTo section says: quadraticCurveTo(cp1x, cp1y, x, y) // BROKEN in Firefox 1.5 (see work around below) Does that mean that Canvas is supported on Firefox 1.5 and above too?

  • Defining your own Ord for a data type

    - by mvid
    I am attempting to make some data structures to solve a graph puzzle. I am trying to define an edge's comparison criteria, but I am not sure how. So far: data Edge = Edge (Set String) Bool How do I tell let the compiler know that I want edges to be declared equal if they have identical sets of strings, and not have equality have anything to do with the boolean value?

  • Java serialization testing

    - by Jeff Storey
    Does anyone know if there is a library that exists to help test if an object graph is fully serializable? It would probably be as simple as writing it out and reading it back in, but I figured someone must have abstracted this already - I just can't find it.

  • generate image of basic figures with perl

    - by jonny
    I am using jalava library as a diagram drawing tool. It displays firgures as images in order to maintain compatibility with majority of browsers. When diagram block is being resized a request is being made and new gif image is generated and send to browser. What I need is generating image of basic blocks, like rounded rectangle, circle, diamond with specified parameters (height, width and color). I want to do all server-side; my server part is written on Perl.
