IMAGEDASHEDLINE(3) 1 IMAGEDASHEDLINE(3) imagedashedline - Draw a dashed line SYNOPSIS
bool imagedashedline (resource $image, int $x1, int $y1, int $x2, int $y2, int $color) DESCRIPTION
This function is deprecated. Use combination of imagesetstyle(3) and imageline(3) instead. PARAMETERS
o $ image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3). o $x1 - Upper left x coordinate. o $y1 - Upper left y coordinate 0, 0 is the top left corner of the image. o $x2 - Bottom right x coordinate. o $y2 - Bottom right y coordinate. o $color - The fill color. A color identifier created with imagecolorallocate(3). RETURN VALUES
Always returns true EXAMPLES
Example #1 imagedashedline(3) example <?php // Create a 100x100 image $im = imagecreatetruecolor(100, 100); $white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF); // Draw a vertical dashed line imagedashedline($im, 50, 25, 50, 75, $white); // Save the image imagepng($im, './dashedline.png'); imagedestroy($im); ?> The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : imagedashedline() Example #2 Alternative to imagedashedline(3) <?php // Create a 100x100 image $im = imagecreatetruecolor(100, 100); $white = imagecolorallocate($im, 0xFF, 0xFF, 0xFF); // Define our style: First 4 pixels is white and the // next 4 is transparent. This creates the dashed line effect $style = Array( $white, $white, $white, $white, IMG_COLOR_TRANSPARENT, IMG_COLOR_TRANSPARENT, IMG_COLOR_TRANSPARENT, IMG_COLOR_TRANSPARENT ); imagesetstyle($im, $style); // Draw the dashed line imageline($im, 50, 25, 50, 75, IMG_COLOR_STYLED); // Save the image imagepng($im, './imageline.png'); imagedestroy($im); ?> SEE ALSO
