Detailed Description
This class renders text to small images on-the-fly.
It attempts to mimic the behaviour of text output, whilst supporting any fonts & character encodings which your system can handle. This class currently requires Imagick.
Member Function Documentation
◆ flush()
| Mike42\Escpos\PrintBuffers\ImagePrintBuffer::flush | ( | ) |
Cause the buffer to send any partial input and wait on a newline.
If the printer is already on a new line, this does nothing.
Implements Mike42\Escpos\PrintBuffers\PrintBuffer.
◆ setFont()
| Mike42\Escpos\PrintBuffers\ImagePrintBuffer::setFont | ( | string | $font | ) |
Set path on disk to TTF font that will be used to render text to image, or 'null' to use a default.
ImageMagick will also accept a font name, but this will not port as well between systems.
- Parameters
-
string $font Font name or a filename
◆ setPrinter()
| Mike42\Escpos\PrintBuffers\ImagePrintBuffer::setPrinter | ( | Printer | $printer = null | ) |
Used by Escpos to hook up one-to-one link between buffers and printers.
- Parameters
-
Printer | null $printer New printer
Implements Mike42\Escpos\PrintBuffers\PrintBuffer.
◆ writeText()
| Mike42\Escpos\PrintBuffers\ImagePrintBuffer::writeText | ( | string | $text | ) |
Accept UTF-8 text for printing.
- Parameters
-
string $text Text to print
Implements Mike42\Escpos\PrintBuffers\PrintBuffer.
◆ writeTextRaw()
| Mike42\Escpos\PrintBuffers\ImagePrintBuffer::writeTextRaw | ( | string | $text | ) |
Accept 8-bit text in the current encoding and add it to the buffer.
- Parameters
-
string $text Text to print, already the target encoding.
Implements Mike42\Escpos\PrintBuffers\PrintBuffer.
