Open Source projects

Chitra Utility function (findDistance(x1, y1, x2, y2)) added to find the distance between two points (link).

Chitra Fix zero width or height oval bug. Due to this context scale was set to zero and no further shapes were drawn (link).

Chitra Gallery home page and gallery detail page added. Also added the sort order to rank the Gallery entry (link).

Chitra Added Makefile and bash script to generate the Gallery images and its thumbnails (link).

Chitra Source code of the Gallery is saved as separate file so that managing or updating code becomes easy (link).

Chitra Added Gallery example: Background (link).

Chitra Added example: Clouds (link).

Chitra Added example: Distance (link).

Chitra Added example: Random blues (link).

Chitra Added example: UUID Thumbnail (link).

Chitra Added new feature to control the co-ordinates and dimentions while drawing the oval/circle shapes (link).

ovalMode(CENTER);
//   X    Y    W    H
oval(100, 100, 100, 100);

ovalMode(RADIUS);
//   X    Y    R1  R2
oval(100, 100, 50, 50);

ovalMode(CORNER);
//   X   Y   W    H
oval(50, 50, 100, 100);

ovalMode(CORNERS);
//   X   Y   X2   Y2
oval(50, 50, 150, 150);

Chitra Added Jekyll based documentation website under docs directory. Theme and documentation work is in progress (link1, link2 and link3).

Chitra Added image tint feature (link).

tint("red");
image("tiger.png", 0, 0);

Chitra Fix image scale when output resolution changes. Image scale was not changed when the canvas resolution changes. For example the following example draws only in 25% of the canvas size because paper size almost increased to 4 times when the default resolution changed to 300 from 72 (link).

auto ctx = new Chitra(600);
ctx.image("img_600.png", 0, 0);
ctx.saveAs("output.png", resolution: 300);

Dataframes(D) Added shift feature to shift the column values as needed by giving the required number of jump value. Negative jump value will shift the column values in reverse order (link).

auto c1 = Column!int([10, 20, 30, 40, 50]);
writeln(c1.shift(1)); // Shifts index by 1 => [0, 10, 20, 30, 40]
writeln(c1.shift(-1)); // Reverse Shifts index by 1 => [20, 30, 40, 50, 0]

auto c1 = Column!int([10, 20, 30, 40, 50]);
auto avgCol = (c1 + c1.shift(1)) / 2;
writeln(avgCol);

Chitra Fixed the translate API example. To reset the translate value used earlier it was using the negative number, but since the data type was wrongly used as ulong negative values were casted to something unexpected (link).

//        X    Y
translate(100, 100); // Move to (100, 100)
rect(0, 0, 200, 50);
translate(-100, -100); // Move back to original position

Chitra Set the default text color to Black. Earlier it was taking the previously used color while drawing any other shape (link).

Chitra Fix the traffic light example by generating multiple drawings (output images) using the newDrawing API (link).

Chitra Added example of using the scale API (Increase or decrease the scale) (link).

Chitra Chitra context management using Lua lightuserdata. This helps to use Chitra with multiple threads using Lua plugin.

Chitra Expose setSize function to use with Lua plugin. When Lua plugin is used, no need to initialize the Chitra context, by specifying size(w, h) the canvas size can be customized. Documentation is not yet available to use the Lua plugin (link).

Kannada Initial version of Phonetic to Unicode and Unicode to Phonetic conversion framework (link).

Kannada Create JS library for both browser and nodeJS using esbuild.

Kannada Added mappings for Phonetic and Unicode (link).

Chitra Added two examples, Traffic signal and Text (https://github.com/aravindavk/chitra-d/commit/894b47b7e7cfef259abf7624962bd29741525cf1).

Chitra Added FOSS United logo as Sponsor to Github project page of Chitra (link).

Chitra Added the new feature to customize the color inputs. Some prefer 0-255 color codes and some prefer floating values from 0-1.0. Chitra now supports chosing the color scale as needed. Default color scale is 0-255 for RGB values and 0-1.0 for Alpha (Opacity control) (link).

//         RGB  A
colorScale(255, 1);    // Default scale
//   R  G  B    A
fill(0, 0, 255, 0.5);  // Blue with Opacity 50%
colorScale(255, 255);
fill(0, 0, 255, 127);  // Blue with Opacity 50%

Chitra Added border and borderColor APIs. Border supports thikness, margin, radius and color (link).

borderColor("blue");
border(5, margin: 10, radius: 7);
