Caption uses tiny text

[powerofvoid]

Code: Select all

convert -size 300x700 caption:"fe fi fo fum" test.jpg

Got the left, expected something more like the right


Code for the right side version:

Code: Select all

 convert -size 300x700 -pointsize 180 caption:"fe fi fo fum" test2.jpg

Might be because I went back to using an old version of imagemagick when I reinstalled.

Code: Select all

convert --version

You need an upgrade. It works fine for me with

Code: Select all

convert -size 300x700 caption:"fe fi fo fum" test.jpg

using IM 6.9.1.4 Q16 Mac OSX. Very similar to your right side image.

Your IM version is about 140 versions old!

[powerofvoid]

I'll try that

Well, that works for small amounts of text, but...

convert -size 300x700 -caption:@lorempipsum.txt test5.jpg

No -caption: ---- remove the minus before caption

My guess is that there is too much text for the smallest pointsize you have on your system for the default font and this may mess up IM's ability to render it properly.

If you cut back on the amount of text and slowly build up, it seems to work fine, until you reach a point where it has no smaller fonts to use.

At that point, you will need to specify the desired pointsize that works for you. Such as

Code: Select all

convert -size 300x700 -pointsize 11 caption:@lorempipsum.txt test5.jpg

[powerofvoid]

convert -size 300x700 -caption:@lorempipsum.txt test5.jpg

No -caption: ---- remove the minus before caption

Code: Select all

convert -verbose -size 300x700 caption:@lorempipsum.txt test.jpg

Well, now it just keeps running for several minutes with no output.

Except that, as you pointed out, 11point font seems to work fine. Why is it using a font smaller than 11p?

[fmw42]

caption: without the minus is correct. Sometimes it takes a long time to render and if it is confused about the correct size, then it could be slow. Does it work without the line breaks?

Perhaps there is a bug. The developers will need to respond.

[magick]

The caption code is modest in its capabilities. For more robust text, use Pango. See http://www.imagemagick.org/Usage/text/#pango. With caption, we got slightly better results by formatting the text. We used fmt -60 to reformat the text and the caption looked reasonable.

[powerofvoid]

Pango seems to be working much better.

EDIT: Except that it doesn't automatically assign a font size to fill the space, which is an important part of what I'm trying to do.

How does one apply fmt -60? Is that a feature in the command line when using caption: or just in the caption: code? If in the code, is that being added in IM 6.9.1.5?

[magick]

The fmt utility is a command-line utility for formatting text. We use it from the vi editor like this:

• -> vi lorempipsum.txt
  :%!fmt -60
