Coloring Book

This applet allows the user to 'color' predefined images by selecting a color and mouse-clicking on the image. The applet will automatically color the clicked pixel with the desired color. Furthermore it will recursively color any pixels of the same original color that lay adjacent to the clicked pixel. Note that this applet is somewhat CPU intensive, and 'color filling' might take a few moments on slower machines.


The applet may be downloaded for free by clicking on the TAR-file link below (read the FAQ if you're not sure what to do with a TAR file). The FAQ also has step by step instructions on how to embed an applet into your own webpage.


Once unTARed, you should find the following classes (plus a '.jar' file if you want to use the archive= attribute in the <applet> tag):


Below are descriptions of all the parameters you may use to customize the applets to your webpages. Be sure to enclose any parameters that contain white space in double-quotation marks. Most parameters have default values in case you do not specify your own values, but the first two parameters (AUTHOR and COPYRIGHT) are necessary. If you are not sure how to incorporate an applet into a webpage (with its parameter names and values), looks at the source of this webpage and the applet embedded for an example, or read the FAQ page.

  • AUTHOR: This parameter must appear exactly as follows:
    <param name=AUTHOR value="Eric Harshbarger,">

  • COPYRIGHT: This parameter must appear exactly as follows:
    <param name=COPYRIGHT value="ColoringBook applet, Copyright 1998, Eric Harshbarger">

  • BGCOLOR: This parameter indicates the background color of the applet. Consult the FAQ page if you are unsure what format to use for the parameter's value.

  • FGCOLOR: This parameter indicates the foreground color of the applet. Consult the FAQ page if you are unsure what format to use for the parameter's value.

  • FONTNAME: This value indicates the fontface used by the applet. Java1.0.2 has the following values from which to choose (must be spelled exactly): TimesRoman, Dialog, Courier, Helvetica, DialogInput, Symbol.

  • FONTSIZE: This value indicates the size of the font used by the applet.

  • FONTSTYLE: This value indicates the style of the font used by the applet. The value should be one of the following: plain, bold, italic, bolditalic.

  • IMAGE.#: This series of parameters (IMAGE.0, IMAGE.1,...) indicates the images that are to be colored. Each parameter value should list the title of the picture then a '|' symbol then the directory path to the image. @ color black and white GIFs lend themselves best to this coloring applet as the filling algorithm scans only for pixels of the exact color as the original clicked pixel (i.e. no anti-aliasing or anything).

  • COLORS: This parameter's value is a list of RGB colors separated by the '|' symbol. As stated in the FAQ, the colors are represented by a comma-separated RGB triplet, so the final parameter will look something like:
    <param name=COLORS value="255,100,125 | 255,0,0 | 0,200,128">
