Dear everyone,

I am new here, I need your help, thanks

how to define -tile, such as watermark's position, 45°degree, not too many , like below


I use this command, but it is too many watermarks and can not 45°degree

Code: Select all

composite -tile -gravity center logofuli.png myg182_01.jpg test.jpg

the result is below, not my wanted

The trick is to create logofuli.png at whatever size you need for the output, containing whatever image you need repeating.

thanks for your reply

I mean the logofuli.png is a fixed png file, how to add some parameter into this command

Code: Select all

composite -tile -gravity center logofuli.png myg182_01.jpg test.jpg

that can make the output watermark file like this:




not this

my english is a little poor, sorry, maybe i did not describe well.

Resize the logofuli.png to fit your image

1. Get the width and height of the output image
2. Resize your PNG file in accordance with the width & height obtained from (1)
convert -resize WidthXHeight logofuli.png logofuli_Resized.png
3. If you want the watermark to be low then you can adjust the width and height accordingly with what you obtained from (1)
4. Use logofuli_Resized.png and apply it on your output image

does this mean we can not add parameter to -tile command that can control the watermark's number and position?

You can rotate the watermark within the composite command:

Code: Select all

composite -tile -gravity center ( logofuli.png -rotate 30 ) myg182_01.jpg test.jpg

I don't know how to change the width and height within the composite command.

You can do more things using convert .... -composite than you can with composite. I suggest you learn the new syntax, since composite is old and may eventually be deprecated. See http://www.imagemagick.org/Usage/compose/#compose and http://www.imagemagick.org/Usage/canvas/#tile
