No output generated in [!1]

[el_supremo]

IM really doesn't like the "[" and I also can't find a way to escape it. It will generate the string if it is "1!]". But a workaround I stumbled on is to add a space at the end of the string.

Code: Select all

convert -size 100x -background none -font Arial -pointsize 72 -fill "#000000" -gravity west caption:"[!1] " test2.png

If this makes the text image too wide you could use -trim.

Another workaround is to put the text in a file. If you put [!1] in a text file, say t.txt, this will draw the text properly:

Code: Select all

convert -size 100x -background none -font Arial -pointsize 72 -fill "#000000" -gravity west caption:"@t.txt" test2.png

Reading the test for a file, or file stream will prevent IM from using any escapes or other text processing on that string.

You don't have to read a file, but could read from stdin "@-"

Code: Select all

    fortune | convert -size 100x caption:"@-" image.png

From a program you can feed the text by using a popen() to run the convert command, and print the text to it.

this is the safest way, to handle any type of text string input, label: caption: -annotate

Sorry space at the end? I don't follow.

This "[!1]" doesn't work, but this "[!1] " does.

We can reproduce the problem you reported and have a patch. Look for it in ImageMagick 6.7.3-0 Beta by sometime tomorrow. Thanks.

This does not work in IM 6.7.3.1 Q16 Mac OSX Tiger

convert -size 100x -background white -font Arial -pointsize 72 -fill "#000000" -gravity west caption:"[!1]" test2.png


But as el_supremo said, add a space before the closing ] and you get what you wanted anyway without the space showing.

convert -size 100x -background white -font Arial -pointsize 72 -fill "#000000" -gravity west caption:"[!1] " test2.png

We reverted the patch because it broke subimage parsing (.e.g. test.jpg[0]). We will need to revisit the problem and come up with a more robust patch.
