I've got wkhtmltopdf working with a header and footer image, and everything spaced well. But the task is to use a full page background image which looks like a sort of frame, with the page text in the center. I thought I could place this in the header, but it doesn't work - maybe the use of a full page header doesn't make sense here.
(These are multi-page documents, which could be of any length).
Any ideas of how to do this?
Thanks in advance.

I have a similar problem, this is what I understood so far:
It's not possible to center the text vertically on the page simply via CSS+wkhtmltopdf on a multi-page document (might find some complex javascript stuff, but it wasn't worth in my case);
since wkhtmltopdf uses webkit, and webkit doesn't support #page rules, it's not possible to define a "paged" background via CSS
Hence what? You will need a little hack and use pdftk
1. In your CSS define:
body {
background: white;
}
(if you have a body tag in your header.html and footer.html make sure that rule applies to them as well)
2. Create a one-page pdf with your background image (using the same page size as your final pdf)
3. Install pdftk and from command line:
$ pdftk yourfile.pdf background background.pdf output yourfile_b.pdf
4. Enjoy :)
You can use a solution BASED on webkit, like HTM2PDF - you'll be able to add a feature called 'stationary' where you can integrate any image as a full page background.

I am trying to set up a simple blog using Metalsmith and the fullPage.js library.
At the moment I have a problem where the height of the section divs upon intial loading are roughly 2 times the correct size.
Ie. when it initially loads the height in the console reads 1563px.
The odd thing is that once I resize my browser window in any way ie. make it larger or smaller, the div(class='section') height will then resize to its correct height in the console and in the browser, and everything is laid out correctly again (with regular sized divs as opposed to the super tall ones that were there previously.
This initial height inconsistency is causing many issues with alignment in my layout, such as the prev/next arrows as well as the div content.
here is a link to my public git repo for this project.
If you want to run this locally you can pull it down, run npm install, then run nf start. You will then be able to access it at localhost/3000.
If anyone has any suggestions that would be much appreciated.
Thanks.
It is not ideal to just public your source. A link reproducing the error would be much better.
In any case, I believe yours is a case of missing the compulsory DOCTYPE declaration at the very start of the page.
Take a look at any examples of fullpage.js. They all have it.
Add this in the first line of your resulting HTML files:
<!DOCTYPE html>
I have a local image that I would like to include in an .Rmd file which I will then knit and convert to HTML slides with Pandoc. Per this post, this will insert the local image :
Is there a way to modify this code to also set the image size?
The question is old, but still receives a lot of attention. As the existing answers are outdated, here a more up-to-date solution:
Resizing local images
As of knitr 1.12, there is the function include_graphics. From ?include_graphics (emphasis mine):
The major advantage of using this function is that it is portable in the sense that it works for all document formats that knitr supports, so you do not need to think if you have to use, for example, LaTeX or Markdown syntax, to embed an external image. Chunk options related to graphics output that work for normal R plots also work for these images, such as out.width and out.height.
Example:
```{r, out.width = "400px"}
knitr::include_graphics("path/to/image.png")
```
Advantages:
Over agastudy's answer: No need for external libraries or for re-rastering the image.
Over Shruti Kapoor's answer: No need to manually write HTML. Besides, the image is included in the self-contained version of the file.
Including generated images
To compose the path to a plot that is generated in a chunk (but not included), the chunk options opts_current$get("fig.path") (path to figure directory) as well as opts_current$get("label") (label of current chunk) may be useful. The following example uses fig.path to include the second of two images which were generated (but not displayed) in the first chunk:
```{r generate_figures, fig.show = "hide"}
library(knitr)
plot(1:10, col = "green")
plot(1:10, col = "red")
```
```{r}
include_graphics(sprintf("%sgenerate_figures-2.png", opts_current$get("fig.path")))
```
The general pattern of figure paths is [fig.path]/[chunklabel]-[i].[ext], where chunklabel is the label of the chunk where the plot has been generated, i is the plot index (within this chunk) and ext is the file extension (by default png in RMarkdown documents).
Un updated answer: in knitr 1.17 you can simply use
{width=250px}
edit as per comment from #jsb
Note this works only without spaces, e.g. {width=250px} not {width = 250px}
You can also read the image using png package for example and plot it like a regular plot using grid.raster from the grid package.
```{r fig.width=1, fig.height=10,echo=FALSE}
library(png)
library(grid)
img <- readPNG("path/to/your/image")
grid.raster(img)
```
With this method you have full control of the size of you image.
Here's some options that keep the file self-contained without retastering the image:
Wrap the image in div tags
<div style="width:300px; height:200px">
</div>
Use a stylesheet
test.Rmd
---
title: test
output: html_document
css: test.css
---
## Page with an image {#myImagePage}
test.css
#myImagePage img {
width: 400px;
height: 200px;
}
If you have more than one image you might need to use the nth-child pseudo-selector for this second option.
If you are converting to HTML, you can set the size of the image using HTML syntax using:
<img src="path/to/image" height="400px" width="300px" />
or whatever height and width you would want to give.
Had the same issue today and found another option with knitr 1.16 when knitting to PDF (which requires that you have pandoc installed):
{width=70%}
This method may require that you do a bit of trial and error to find the size that works for you. It is especially convenient because it makes putting two images side by side a prettier process. For example:
{width=70%}{width=30%}
You can get creative and stack a couple of these side by side and size them as you see fit. See https://rpubs.com/RatherBit/90926 for more ideas and examples.
Another option that worked for me is playing with the dpi option of knitr::include_graphics() like this:
```{r}
knitr::include_graphics("path/to/image.png", dpi = 100)
```
... which sure (unless you do the math) is trial and error compared to defining dimensions in the chunk, but maybe it will help somebody.
The knitr::include_graphics solution worked well for resizing the figures, but I was unable to figure out how to use it to produce side-by-side resized figures. I found this post useful for doing so.
I dont know what kind of success i'll have from this post but struggling at the moment to get a reply on the rockettheme forums.
I have downloaded this template (Kinetic) from Rockettheme.com (demo below;)
http://demo.rockettheme.com/?template=kinetic
I have changed it to come out looking like the link below;
http://evolve.gen.nz/
However im really struggling to differentiate the footer from the rest of the website. Im looking at changing it to a light grey however I cannot make it stretch right across the website as the footer is located in the container and stops at either edge of the container.
is there anyway to make a footer colour go right across the page?
(the same as the following website, if you go down to the bottom of the page and you will see a dark grey, charcoal colour)
http://www.colmanweb.co.nz/websites/refuge/
Any ideas on how I could get this achieved?
Thanks
You just need to edit the index.php file of the template, should be at templates/kinetic/index.php roughly. If you head to the bottom, you will find a div with rt-footer. You will want to pull this entire div statement out and paste it outside of the div with an id rt-surround. Your best bet is to find rt-debug and paste it just above.
I run a lot of sites off the base gantry template from Rocket Theme and do this type of thing often, so it should work.
Two issues you may run into. If you don't get the right closing div tag, you can get some weird output if the divs aren't closed properly. So be careful and use the indentation to help you.
Second, there may be some css styling that is specific to the old heirarchy. I doubt it in this case, but it can happen. You may have to fix some of the css styling.
i have an html file and i'm using Itext 2 with flying Saucer to convert it to a pdf file.
The problem is that if an image starts near the page end, flying saucer render a portion of it it the end of the current page and the rest in the beginning of the next page.
How to say that i want the entire image on one page only?
You can add this to your print css:
img {
page-break-inside: avoid;
}
The user guide (PDF) mentions it.
There appears to be a bug in FlyingSaucer that is causing issues with page-break-inside: avoid.
The issue manifests when css: orphans kicks in, when a paragraph is laid out towards the end of a page and the minimum number of lines cannot be rendered on the page. Then the block box layout state machine appears to go wrong.
We have pushed a fix to a fork here: https://github.com/krokiet/flyingsaucer/tree/master
At some point we will raise a pull request to get this merged back into the main code base.
I have the same problem but
img {page-break-inside: avoid;}
is not the final solution. Yes it has impact for result and in some situations it works but not always.
Here is some more details about the same or similar problem.

im building a webshop in Drupal and i was wondering if you could help me with the following problem:
I got one big image frame (500x500) and 5 little image thumbnails(95x95) underneath the big one.
How can i realise that if the visitor clicks on the thumbnail, the big image frame gets filled with that specific image?
jQuery is the right direction, but the strength of Drupal is based on doing things "the drupal way", which means, I guess in your case, to use Views as the origin for the thumbnails using imagecache + lightbox, and somehow change the main "frame".
I used jcarousel in some cases (for different but similar uses) and it works nice. I guess it is possible to trick it to do what you need, or - better - to find an existing module that do what you want.
I know, many Drupal buzzwords, and a stiff curve to overcome, but this is the right direction in case you want to base your site on Drupal.
If you don't need all of these, and want a static page+jquery, Drupal might be an overkill altogether.
If you use Views, Imagecache, and the Lightbox2 module, you can create image galleries out the arse and tell it to link the field to its large size and use Lightbox2 as the method. This is how I do most of my galleries.
Drupal uses jQuery so you can write a simple jQuery script to handle this (not sure if there's already a plugin to do that). Just add all the img tags (make sure all of them except the first one are hidden[display=none]). Then when a thumbnail is clicked/hovered do a $(big_img_holder).replace() with the tag for the image to be shown. Tell me if you want to see some code and I'll try to show you.
You can see this plugin as an exapmle. Just replace the numbers on the right with thumbnails and you're ready to go ;-)
