Código PHP:
$upfilename = "Untzu.gpx";
$profile = "http://chart.apis.google.com/chart?cht=ls&chco=000000&chm=B,76A4FB,0,0,0&chd=s:ATSTaVd21981uocA&chf=bg,s,efefef&chtt=aia.gpx-9.44Km&chd=t:431.29,441.38,449.55,462.53,477.93,484.63,499.54,500.02,526.45,532.24,540.41,567.32,573.57,574.52,576.44,613.47,634.14,651.91,664.4,669.71,676.9,712.96,720.15,725.45,717.77,705.73,712.96,713.45,733.14,737.46,772.09,802.84,817.26,832.16,833.11,830.7,829.76,799.95,784.59,798.03,822.53,818.21,825.92,803.79,809.09,788.91,777.85,794.19,805.71,810.04,804.28,793.7,783.61,766.79,750.94,740.36,731.7,725.94,706.22,689.88,677.88,665.38,646.15,631.73,621.15,615.39,588.48,579.33,554.83,550.99,537.51,523.59,516.85,520.69,525.99,525.99,521.18,514.44,508.19,502.92,497.62,491.86,483.2,478.38,463.02,454.85,445.22,436.11,420.23,421.66,429.37,434.19,421.2,421.2,442.36,449.06,454.37,463.97,468.29,481.28,497.13,507.71,518.28,537.51,553.36,562.02,572.11,576.93,578.85,582.23,586.07,591.83,599.02,612.5,614.42,610.09,606.73,605.3,608.17,592.78,587.01,585.09,585.09,577.9,562.02,552.91,539.92,535.59,523.1,513.5,496.67,472.14,470.21,458.21,454.37,449.55,439.95,437.54,434.19,431.78,431.29,424.07&chg=20,50,1,5&chxt=x,y&chxr=0,1,9.44|1,0,833.11&chds=420.23,833.11&chs=800x250";
include 'class.image.transparency.php';
$transparency = new Image_Transparency;
// range of transparency (from 1 to 100)
$transparency->pct = 90;
// Source Image
$transparency->source_image = $profile;
// New Image Name (optional)
$transparency->new_image_name = $upfilename;
// Save to folder (optional)
$transparency->save_to_folder = '../imagesProfile/';
$process = $transparency->make_transparent();
if($process['result'])
{
$profile = $process['new_file_path'];
}
No me da ningun resultado al pasarlo por la clase.
