GD Image help

[jay83r]

Hi there, i want to draw dynamic lines by using ImageLine($image, 0, 0, 100, 100, $color) but i want to store the line co-ordinates in a mysql database so i can give each line a meaningful name and call them and display when I want to... anyone with anyideas?

Seems like you've summed up exactly what you should do.

 

I'm not sure what you've left out?

 

Just keep all the lines in a table, with x1,y1 and x2,y2 columns, along with columns for an id and whatever meta data you need to store.

 

If you need help with the actual code, I suggest posting what you have so far. If you don't even know where to start, I suggest checking out the introduction section of the PHP manual.

i've got this but i'm totally lost with it, i'm getting a header issue, and im not sure how to to do the mysql part.

<?php

$image = ImageCreate(200, 50);

$background_color = ImageColorAllocate($image, 255, 255, 255); // white

$gray            = ImageColorAllocate($image, 204, 204, 204); // gray

 

ImageFilledRectangle($image, 50, 10, 150, 40, $gray);

$image = ImageCreate(200, 50);

$background_color = ImageColorAllocate($image, 255, 255, 255); // white

$gray            = ImageColorAllocate($image, 204, 204, 204); // gray

 

ImageFilledRectangle($image, 50, 10, 150, 40, $gray);

 

header('Content-type: image/png');

 

ImagePNG($image);

 

 

  ?>

i've fixed the header issue, and are able to draw a line with text, but how to i reference this to a table in a database

 

<?php

// set the HTTP header type to PNG

header("Content-type: image/png"); ?>

<?php

 

header ("Content-type: image/png");

$handle = ImageCreate (640, 480) or die ("Cannot Create image");

$bg_color = ImageColorAllocate ($handle, 255, 255, 255);

$txt_color = ImageColorAllocate ($handle, 0, 0, 0);

$line_color = ImageColorAllocate ($handle, 0, 0, 0);

ImageLine($handle, 0, 0, 200, 0, $line_color);

ImageString ($handle, 8, 5, 18, "base line", $txt_color);

ImagePng ($handle);

?>
