Hi there,
i’m trying to print out some images saved out from Touch.
I found a python script for this, wich workes as long as i run it through PyCharm.
If i run it within Touch it gives me some errors wich i don’t know how to handle.
import win32print
import win32ui
from PIL import Image, ImageWin
#
#Constants for GetDeviceCaps
#
#
#HORZRES / VERTRES = printable area
#
HORZRES = 8
VERTRES = 10
#
#LOGPIXELS = dots per inch
#
LOGPIXELSX = 88
LOGPIXELSY = 90
#
#PHYSICALWIDTH/HEIGHT = total area
#
PHYSICALWIDTH = 110
PHYSICALHEIGHT = 111
#
# PHYSICALOFFSETX/Y = left / top margin
#
PHYSICALOFFSETX = 112
PHYSICALOFFSETY = 113
printer_name = win32print.GetDefaultPrinter ()
file_name = "test.jpg"
#
#You can only write a Device-independent bitmap
#directly to a Windows device context; therefore
#we need (for ease) to use the Python Imaging
#Library to manipulate the image.
#
#Create a device context from a named printer
#and assess the printable size of the paper.
#
hDC = win32ui.CreateDC ()
hDC.CreatePrinterDC (printer_name)
printable_area = hDC.GetDeviceCaps (HORZRES), hDC.GetDeviceCaps (VERTRES)
printer_size = hDC.GetDeviceCaps (PHYSICALWIDTH), hDC.GetDeviceCaps (PHYSICALHEIGHT)
printer_margins = hDC.GetDeviceCaps (PHYSICALOFFSETX), hDC.GetDeviceCaps (PHYSICALOFFSETY)
#
#Open the image, rotate it if it's wider than
#it is high, and work out how much to multiply
#each pixel by to get it as big as possible on
#the page without distorting.
#
bmp = Image.open (file_name)
if bmp.size[0] > bmp.size[1]:
bmp = bmp.rotate (90)
ratios = [1.0 * printable_area[0] / bmp.size[0], 1.0 * printable_area[1] / bmp.size[1]]
scale = min (ratios)
#
#Start the print job, and draw the bitmap to
#the printer device at the scaled size.
#
hDC.StartDoc (file_name)
hDC.StartPage ()
dib = ImageWin.Dib (bmp)
scaled_width, scaled_height = [int (scale * i) for i in bmp.size]
x1 = int ((printer_size[0] - scaled_width) / 2)
y1 = int ((printer_size[1] - scaled_height) / 2)
x2 = x1 + scaled_width
y2 = y1 + scaled_height
dib.draw (hDC.GetHandleOutput (), (x1, y1, x2, y2))
hDC.EndPage ()
hDC.EndDoc ()
hDC.DeleteDC ()
I found different posts about that ‘_imaging’ thing but none of the mentioned solutions worked for me.
My current version of pillow is 5.1.0.
Thanks in advance
