# Too much white space above png figure after latex-dvi-pdf compilation

I have searched the other question here extensively as the problem of spacing seems to re-occur often, but still have not found the solution to my specific problem:

I have way to much white space above my figure! Even after lowering the \floatsep (has no effect at all it seems). The figure itself does not have any white space on top (I have double checked). I have also tried by defining the bounding box instead of the natwidth,natheight, but still the same output so it is driving me crazy.

This is a MWE which results in the given picture which is of course not what I desire

• It is impossible to really debug without the image but you almost never want to specify natwidth and natheight if they are the actual natural size of the figure they are not needed, and if they are not exactly the size of the figure then strange things happen. If you could reproduce the problem using example-image (that most people have already) it would be easier to help Mar 4, 2016 at 11:28
• Welcome to TeX.SX! The first debugging step is to enclose the \includegraphics in an \fbox, so as to see whether the white space is in the picture itself. Mar 4, 2016 at 11:28
• egreg: the white space is not in the picture itself, as I said I already checked that as mentioned in the post Mar 4, 2016 at 12:23
• the problem can be reproduced with any png picture (of course after updating to the correct pixel size). Sorry I was not aware of the existence of example pictures and I am not quit sure how to use them Mar 4, 2016 at 12:27
• carlisle: I am specifying the natwidth and natheight because otherwise my picture was not showing because I am using the Latex->DVI->pdf sequence to compile. This is not my choice but cannot be changed as I am using a template of my university and otherwise a whole lot of other stuff will change which I have no idea on how to correct (I am new at this). So I have found this solution here. Mar 4, 2016 at 12:27

I think this might be down to conflicting definitions of the size of a 'pixel'. Using preview, I find that this image has size 14pt x 14pt (approximately), or 48 pixels x 48 pixels.

However, the following experiment using pdftex produces something quite different:

*\newdimen\mydimen
*\mydimen=1px
*\showthe\mydimen
> 1.00375pt.


So 1px = 1pt (more or less). Using the image in a document, and compiling with latex+dvipdfmx produces white space if I use 48px for natwidth and natheight, but the problem goes away if I use 14pt.

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\fbox{\includegraphics[natwidth=48px,natheight=48px,width=5cm]{xboard.png}}%
\fbox{\includegraphics[natwidth=14pt,natheight=14pt,width=5cm]{xboard.png}}%
\end{document}


So, try using measurements in points, rather than pixels.

david carlisle, since you made the comment about the natwidth definition I started searching more in this direction and more specifically how I can avoid to use this. So I have found that if I include this, it works without needing to define the size of the image and the annoying white space disappears. Unfortunately, also my figure in my more complex document disappeared. But I figured out that was because I was also using the color package which was apparently interfering, but I solved that by putting the color package before the graphicx package and my figure re-appeared. Thank you for your help!
