I'm using the mimo code app for coding. I saved a picture from google in the folder "Saved Pictures". The file name is "generic background". I did the code <="/Saved Pictures/generic background.jpg">. But the image does not show. Instead what shows is a small file. Don't really know how to get the image to show. I did used img src before =, but I need 10 reputations points to post an image even though I was just trying to show the code.
This question is motivated by the answer given in this question
Using the animate package without adobe
I want to create latex beamer presentations without relying on adobe, as it is a pain.
I followed the instructions given in the post's answer, and when compiling the given example code, the output were 4 .svg files, and I have no idea on what to do with them.
Something tells me they should be embedded into an html file that produce a slide-presentation, but I'm a complete noob in html and I've not been able to find an answer on how to achieve this.
No additional wrapper for the individual .svg files is necessary. Simply open the first .svg file in your browser and use the little arrows at the top right for navigation. They automatically link to the next slide.
I am working on the .md file in the following location:
https://github.com/markroche92/SDND-Traffic-Sign-Classification/blob/master/writeup_template.md
None of my linked images are appearing when I view the .md file in Github. I have used the following markdown code to attempt to link the images:
---

The following histogram shows the distribution of training, validation and
test set images per label:
![alt text][image1]
An example image was visualised for each label. Three are displayed below:
![alt text][image2]
![alt text][image3]
![alt text][image4]
Each image has three channels (red, green, blue). The three channels are
visualized below for an example image:
![alt text][image5]
However, none of the images seem to be appearing when .md is viewed on Github. Can anyone show me where I am going wrong here?
In the actual .md file you are not using relative URLs like in your supposed quote, but absolute ones like this:
https://github.com/markroche92/SDND-Traffic-Sign-Classification/blob/master/structure.JPG
This won’t work because it is actually a standard GitHub file page, not the image itself. To link to the image, remove /blob from the path and change the domain to rawgit.com – or actually use relative URLs with or without leading ./, but make sure to get the letter case right.
https://rawgit.com/markroche92/SDND-Traffic-Sign-Classification/master/structure.JPG
structure.JPG
I also had this issue on some of my images, but not others. It ended up being how I capitalized my image names in my markdown file. For example:
Image name on my computer:
oneGreatImage.png
Image name in my Markdown file:
onegreatImage.png
When I capitalized the G again and pushed the changes it loaded just fine.
It appears that GitHub is VERY picky about matching the filenames on the images so double check that.
I am working with an old system of palletes. When I export an image, it also creates an pallete with 15/16 colors. But when I try to replicate the same result, the program does not recognize the image which I just created. To analyse what happened, I opened some images with notepad and compared them with my "creation" and I noticed quite some differences.
But the most interesting thing was that at the beginning of my images' code was the type "BM6", while they should be "png" or "bmp". I think that is some thing of codification, but I cannot find anything about it.
If the image file is properly formed, then you can take your .bm6 file and simple change / rename the extension to .bmp. And it should suddenly be an image.
.bm6 can result from creating an image file using a text editor, as seen here.
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.
