I use heatmap.2 in R to draw a figure and save it as PDF format. When I opened the PDF files, it looked good.
PDF Figure
But when I loaded the PDF file into Inkscape. It seemed that the color key is not as bright as what I saw in PDF files.
PNG file exported from Inkscape. Please focus on the colorkey.
Can someone help me on this?
Thanks.
This has probably got something to do with the used colorspace, try changing the colorspace in the pdf-output device with the colormodel option.

I am using Qt PDF module to open a PDF file. How can I take a screenshot of part of the file and save it?
Since I guess this is impossible, I will convert the PDF to a image using pdf2image and work with images
I have used addlogo to my leaflet map which displays my organizations' logo on the bottom right of the map.
This is logo visible in the viewer within R. However when I save the map the logo is not visible in either a png or HTML format. Please view the code below and the attachments.
Any advice would be appreciated.

I have used webshot to save as HTML but still the same issue
save the file to png
mapshot(m, file = "myfilepath", remove_controls = NULL)
The output should be saved with the logo at the bottom right hand visible.
Instead of using webshot, you should consider to try webshot2. See my detailed answer to the similar case.
The code:
# Webshot and phantomjs have been previously installed.
library(webshot2)
So I know how to show images  but I want the image to be saved on the html file so when I open the html file on someone else's computer I should be able to see the image. I will get an error message saying the path is wrong if I try to knit the .Rmd file.
The image is referenced absolutely on my computer but I don't want that. Is there a way to do?
I apologize in advance if this question is a duplicate, but I'm having trouble finding a proper solution. Thanks
A simple solution would be to import the image into R and then print it.
I am trying to open a normal PDF file in Photoshop. This is how my file should look like
And this is how it looks opening it on Photoshop:
Since Photoshop is not my best area i am having hard time to describe what my problem is hence the bad title. Searching in google with no knowledge of what it is was also hard.
Any suggestions?
EDIT
Here is the PDF file as requested: https://files.fm/u/hq8c4kt9
Can you put a link to your pdf file ? It seems like your pdf have ellements outside of his dimensions. You can maybe try playing with the "crop to" options in the "import pdf" dialog. (first screenshot of this page)
When I make my knitr document, I see the html file in my directory. I load the file and it looks great.
However, I'm curious where the pictures are:
It gives me locations like:
img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAACQAAAAYACAYAAAAjFnetAAAEJGlDQ1BJQ0MgUHJvZmlsZQAAOBGFVd9v21QUPolvUqQWPyBYR4eKxa9VU1u5GxqtxgZJk6XtShal6dgqJOQ6N4mpGwfb6baqT3uBNwb8AUDZAw9IPCENBmJ72fbAtElThyqqSUh76MQ ...."
Where exactly is the image?
This IS the image directly encoded in html. http://en.wikipedia.org/wiki/Data_URI_scheme
see f.e. this stack overflow question: Embedding Base64 Images
