Fixed-Price – Est. Budget: \$250.00 Posted
I'm using PHP imagick to draw bezier curves. I have a function (finControlPoint) that will draw a 3 point bezier curve that passes through each point. The function looks like: \$s1 = array("x" => \$var1, "y" => 0);//start \$s2 = array("x" => \$var2, "y" => \$var3); \$s3 = array("x" => \$var4, "y" => \$var5);//end \$smp = findControlPoint(\$s1, \$s2, \$s3); function findControlPoint(\$s1, \$s2, \$s3){ // Unit vector, length of line s1,s3 \$ux1 = \$s3['x'] - \$s1['x']; \$uy1 = \$s3['y'] - \$s1['y']; \$ul1 = sqrt ...
• ## CRC checksum generator

I need to be able to create CRC data based on a dataset. Most of the datasets are only 64bytes and the last 4 bytes are the checksum, however there is a defined format for this but it's out of my skill set to tun it into code. This uses Reed-Solomon (N, N-4) of GF (256). P(x) = x8 + x4 + x3 + x2 + 1 A primitive element α in GF (256) shall be α = ( 0 0 0 0 0 0 ...
