Hi there! I''m studying RMagick graphics manipulation gem, and I need to put small text about size 8 to 11 px on pictures. I found that text() method prints quite blurred text. And I could not get clear text chosing different values for methods font, font_family, font_style, font_weigth. I attached a picture. In the left of it you can see what RMagick generates for me and in the right you can see the example of clear text I need RMagick to generate for me. What can I do to get clear text. Any ideas?

In my text drawing, I set stroke to transparent and fill to the desired text color. Also, you could try turning off antialiasing. I ended up using anti-aliasing, but rendering the text at double size and scaling down for acceptable results. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Something like at attached picture (I used pixel editor :) to prepare it) And It seems to me that scaling down could not make accurate symbols.

I would have something like:
gc.stroke(''transparent'').stroke_antialias(false)
gc.fill(''black'')
The stroke_width setting won''t have any effect on the text. I also
never saw any variation from using the font_style or font_weight
settings. I''m not sure if turning off antialiasing has any effect on
text, since I now have that commented out in my code. I still turn
off antialiasing when drawing lines because I only draw rectangles.
On an angled line you might need it.
The font you choose may also have something to do with it. Run
convert -list font
at the command line to see the available fonts and families on your
system.

I''ve checked again and found that result defends on both callings @gc.stroke(''transparent'').stroke_antialias(false) @gc.text_antialias = false the best result (which I showed upper) produced by calling both methods. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

hmm...I never noticed the text_antialias method before. I''ll have to remember that the next time I run into issues. Glad I could help!
