Summary

The SvgUtility and SvgUtilityBuilder classes provide a convenient and streamlined way to create, parse, and modify SVG files in Java. SvgUtility allows for the manipulation of SVG files with methods such as parsing SVG files to strings, changing colors, classes, and attributes in SVG files, adding styles, and exporting SVG files to a file path. SvgUtilityBuilder implements the builder pattern by allowing for the modification of various parameters using builder methods, which are then used in the appropriate methods of SvgUtility to modify the SVG file.

SvgUtility

The SvgUtility class provides a set of static methods for parsing, modifying, and exporting SVG files in Java. Some of the key features and methods of SvgUtility include:

• The ability to parse an SVG file to a string using the parseSvgToString() method.
• The ability to change the fill color of an SVG using the changeColor() method.
• The ability to change the class of an SVG using the changeClass() method.
• The ability to add a new class to an SVG using the addClass() method.
• The ability to add a new attribute to the opening tag using the addAttribute() method.
• The ability to add a new style to the existing style attribute or create a new style attribute using the addStyle() method.
• The ability to export an SVG file to a file path using the exportSvgToFile() method.

SvgUtilityBuilder

The SvgUtilityBuilder class provides a way to modify an SVG file using a set of builder methods before building and returning the modified SVG as a string. Some key features and methods of SvgUtilityBuilder include:

• The ability to set the SVG file to be used by SvgUtility methods with the setSvgFile() method.
• The ability to set the HTML class to be used by SvgUtility methods with the setHtmlClass() method.
• The ability to add a new attribute to the opening tag using the setAttribute() method.
• The ability to change the fill color of an SVG using the addColor() method.
• The ability to set a new CSS class for the SVG using the addNewClass() method.
• The ability to add a new attribute to the opening tag using the addNewAttribute() method.
• The ability to add a new style to the existing style attribute or create a new style attribute using the addNewStyle() method.
• The ability to export the modified SVG file to a file path using the addFilePath() method.
• The ability to add a new CSS class to the SVG using the addClass() method.

Overall, both SvgUtility and SvgUtilityBuilder provide a comprehensive set of tools for working with SVG files in Java, making it easier to manipulate and create SVG files in code.

Examples

Modifying an SVG File with SvgUtilityBuilder

This example uses the SvgUtilityBuilder to create a modified SVG file with various modifications. It sets the SVG file to be modified, adds an HTML

try {
    String modifiedSvg = new SvgUtilityBuilder()
            .setSvgFile("example.svg")
            .setHtmlClass("my-class")
            .addNewAttribute("viewBox=\"0 0 100 100\"")
            .addColor("#FF0000")
            .addNewClass("new-class")
            .addNewStyle("stroke: black;")
            .build();
    System.out.println(modifiedSvg);
} catch (IOException e) {
    e.printStackTrace();
}

Parsing an SVG File to a String

This example uses the parseSvgToString() method to read an SVG file at "example.svg", add a "class" attribute with the value "my-class", and add additional attributes width and height to the opening <svg> tag.

try {
    String svgString = SvgUtility.parseSvgToString("example.svg");
    System.out.println(svgString);
} catch (IOException e) {
    e.printStackTrace();
}

Changing the Fill Color of an SVG

This example uses the changeColor() method to change the fill color of an SVG file at "example.svg" to red (#FF0000).

try {
    String svgString = SvgUtility.changeColor("example.svg", "#FF0000");
    System.out.println(svgString);
} catch (IOException e) {
    e.printStackTrace();
}

Adding a New CSS Class to an SVG

This example uses the addClass() method to add a new CSS class "my-class" to an SVG file at "example.svg".

try {
    String svgString = SvgUtility.addClass("example.svg", "my-class");
    System.out.println(svgString);
} catch (IOException e) {
    e.printStackTrace();
}
