In what situations would it be necessary to adjust the Document type in Joomla when working with image generation libraries like pChart?

When working with image generation libraries like pChart in Joomla, it may be necessary to adjust the Document type to ensure that the generated images are displayed correctly. This is because the default Document type in Joomla may not be compatible with the image generation process. To solve this issue, you can adjust the Document type to 'raw' before generating the image. 

// Adjust the Document type to 'raw' for image generation in Joomla
$doc = JFactory::getDocument();
$doc->setMimeEncoding('image/png');
$doc->setContentType('image/png');
$doc->setType('raw');
