Question about images in PDF and a bug

[wikimatze]

Hi Kouhei,

Question

I uploaded my pictures on flickr and you can find the markdown files under bitbucket. I normally took the medium size for them.

Creating the presentation in a terminal (I think it opens Rack) with rabbit slides_vim_and_git.md they look awesome and sharp. But creating a PDF out of them with rabbit -t rabbit-theme-nyankosakana -p --type file --slides-per-page 1 -o slides.pdf slides_vim_and_git.md the pictures are looking terrible. Is there a solution hint=

Bug

Render the following line on some slide

- `:Gstatus` ... git status
  - `<C-n>` ... go to the next file
  - `C-p` ... go to the previous file

will give me the following error when I hit the slide:

I found out, that the problem is based on the < and > signs.

But creating a PDF out of them with rabbit -t rabbit-theme-nyankosakana -p --type file --slides-per-page 1 -o slides.pdf slides_vim_and_git.md the pictures are looking terrible. Is there a solution hint=

Use relative_height='100' or relative_width='100' parameter like:

![](https://farm4.staticflickr.com/3945/15426451090_08b9a6f316_z_d.jpg){:relative_height='100'}

Rabbit scales your pictures according output device size automatically.

I found out, that the problem is based on the < and > signs.

I confirmed it. I'll fix it tonight.
