creating a string for base64 from in memory image?

[MrUmunhum]

Hi group,

 

  I need to create a string to be used by base64_encode to build an SVG file. The source for the string is an image I built in memory.

$img = imagecreatetruecolor( 50,50 );
Other stuff, draw circles, test, ect.

I currently write it out to disk with:

imagepng( $img, "$Name.png" );

 

Then read it back in and process it to create an SVG file.

 

I would like to avoid writing it to disk, so how can I create a string for base64_encode from an in memory image??

 

Thanks for your time.

You would use output buffering (ob_start) and let imagepng() send the output to the buffer. Then use ob_get_contents to get the image data into a string.

Thanks, perfect.
