    <p>I have this little animation here that animates in a repeated seamless pattern.</p> <p>I have text, colored white, in the middle of the canvas that the looped shapes pass over. What I am trying to work out is when the white bars pass over the text it turns black. So as half the white bar goes over the T of "Text", half the T would be black and the half not covered would be still white on a diagonal.</p> <p>Would this be done with splitting up the letters? By doing masking, or using vector images?</p> <p>Here is a graphic example of what I'm trying to achieve. </p> <p><a href="http://imm.io/2Qsb" rel="nofollow noreferrer">http://imm.io/2Qsb</a></p> <pre class="lang-java prettyprint-override"><code>drawLine wob1; drawLine wob2; drawLine wob3; drawLine wob4; drawLine wob5; PFont helv; drawText title; void setup() { //frame.setResizable(true); size(320, 480); smooth(); frameRate(50); wob1 = new drawLine(0); wob2 = new drawLine(200); wob3 = new drawLine(400); wob4 = new drawLine(600); wob5 = new drawLine(800); title = new drawText(); } void draw() { background(#000000); wob1.increment(); wob1.display(#ffffff); wob1.pos(); wob1.boundary(); wob2.increment(); wob2.display(#ffffff); wob2.boundary(); wob3.increment(); wob3.display(#ffffff); wob3.boundary(); wob4.increment(); wob4.display(#ffffff); wob4.boundary(); wob5.increment(); wob5.display(#ffffff); wob5.boundary(); title.rendertitle(#ffffff; } class drawLine { int x = -480; int y = 0; int count; drawLine(int offset) { this.x = this.x + offset; } void increment() { this.x += 3; this.y += 4; } void display(int col) { //noStroke(); fill(col); //translate(0,0); rectMode(CENTER); rotate(-PI/3.0); rect(x,y,100,3000); rotate(PI/3.0); } void pos() { println(this.x); //if(this.x &gt;= -218 &amp;&amp; this.x &lt;= 207){ colr = #000000; } else { colr = #ffffff; } } void boundary() { if(this.x &gt; 520) { this.x = -480; this.y = 0; } } } class drawText { drawText() { helv = loadFont("Helvetica-Bold.vlw"); } void rendertitle(int colr) { fill(colr); textFont(helv, 30); text("Text goes here", width/2, height/2, 240, 50); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
