===================Imagetool using =====================

First import the Imagetool tool:

require_once ' ImageTool.class.php ';

Then instantiate the Imagetool object:

$imageTool New Imagetool (' img/oppman.jpeg ', ' out/'); // picture path, output folder

First, generate compressed pictures

$imageTool true); // compression width, compression height, whether to save $imageTool->showimage ();

Second, add text watermark

$imageTool true); // content, size, font, save $imageTool->showimage ();

Third, add image watermark

$imageTool true); // watermark Path, transparency, whether to save $imageTool->showimage ();

Only as temporary image output:

$imageTool->addtextmark (' Fast output ', ' Res/micro.ttf ')->showimage ();
