Hi All,

word = "Nokia"

How do i print a word on canvas in center align ? i do not want to fixed coordinate on the canvas because the a word is changing dynamically so the word size would be increase like (word = "Computer"). Please help me is there any solution for this issue.

Hi,

Check out the graphics section from the PyS60 Library Reference. It has a paragraph about the measure_text method:

measure_text(text[, font=None, maxwidth=-1, maxadvance=-1])

Measures the size of the given text when drawn using the given font. Optionally you can specify the maximum width of the text or the maximum amount the graphics cursor is allowed to move (both in pixels).

Returns a tuple of three values:

• the bounding box for the text as a 4-tuple: (topleft-x, topleft-y, bottomright-x, bottomright-y)
• the number of pixels the graphics cursor would move to the right
• the number of characters of the text that fits into the given maximum width and advance

So you can measure the size of the word you want to write and calculate the coordinates at which you want to write it so it would be in the center.

This will help you:

size = img.measure_text(string, (None, None, FONT_BOLD))
img.text(((screen_width-size[1])/2, vertical_position), string, 0xffffff, (None, None, FONT_BOLD))

Well, what I usually do is measuring the text as mentioned before and do some calculations:

import graphics
import sysinfo

x, y = sysinfo.display_pixels() #gets width and height of the screen
img = graphics.Image.new((x,y))
text = "Welcome!"

((x1, y1, x2, y2), dummy, dummy) = \
      img.measure_text(text, font='title')
img.text((x/2-x2/2, y+y1), text, (255, 0, 0), 'title')

By the way, also check Font Test by Jouni Miettunen, which is a perfect example for this



Hope it helps,

Rafael.
