We are currently converting TIFF files to PDF using GraphicsMagick. The TIFF is coming from an eFAX and has a (pixel) resolution of 1728x2200.
If you do the conversion with tiff2pdf or just open it on Preview and convert export it to PDF, it is generated with a MediaBox value of 612x792 point, which is what is expected.
However graphics magick generates a MediaBox of 1728x4400 and a CropBox of 610x792. It all looks good if you open it on a PDF viewer because it's using the CropBox but if you're feeding it to GhostScript after, you don't get the Image on the full page but as a small square inside the document.
The lazy solutions would be to change for Tiff2PDF or add -dUseCropBox to our GhostScript command but I'd like to know what GraphicsMagick option should be used to have the PDF with the good MediaBox. It's like it doesn't understand that the resolution is in Pixels and not in Point. Hope somebody has insights
I opened one PNG file in Inkscape and exported it as SVG. When I opened that file with notepad I came to know that the PNG file is embedded within it. If the conversion happened then the resulting file should have only SVG related tags. It shouldn't embed the image within it. Or Am I doing anything wrong.
Note: Save as option also producing the same kind of file. I am using Inkscape version 0.48 in Windows 7 - 64 bit.
This is a bit of an old thread, but it comes up early in Google so I thought I'd contribute something.
In Inkscape, you must do a trace to change the image into SVG. Look at the Path | Trace bitmap menu item and play with the options on that screen.
After creating the trace, you can remove your source image and have a pure svg in your saved file.
I've found it helpful to create layers in Inkscape and move the source image to one layer and put the trace on another layer to let me make quick comparisons using the 'hide layer' buttons.
BTW, your source image can be anything - bmp, jpg, png, etc.
A .png file is a raster image file. In order to convert it to a vector graphic based format like .svg and have it be "native" svg rather than an included image you are going to either have to use a program that can rasterize it or in Inkscape trace the bitmap and turn it into paths. Inkscape provides information on tracing: http://inkscape.org/doc/tracing/tutorial-tracing.html
How do I convert an svg file to an image using Go ?
I found the amazing svgo library and would like to use it to generate a custom set of playing cards. The idea is to store the text and layout of a card in a text file and then read and process it with go. This would be a huge improvement of my current workflow where I use gimp to edit each individual card. The problem is that I need to have an image of the card for printing. Preferably png since the printing script so far only works with that format. But I could easily adapt it to accept jpeg, too.
Unfortunately svgo doesn't seem to offer export functionality. Can you recommend a go library to convert svg to png ?
One possible strategy is to write your SVG to files and invoke an external tool to convert them. For example, ImageMagick and its related GraphicsMagick will both convert SVG to PNG via command-line options. You would need to use the convert verb, possibly within their batch support if you're converting lots of images at once.
GraphicsMagick has bindings for C and Go and other languages that you could use directly from your Go scripts, although I've not tried this myself.
I can't find a native Go library to do it, but there seems to be a way to convert an HTML canvas element to PNG quite simply in Javascript.
You can therefore output SVG to an HTML canvas element, and then use JS to export to SVG.
See this answer for details.
I am trying to convert svg image to eps using Imagemagick. I am able to convert the image using Imagemagick, but the image size is too high when compared to the original image size and the content is not displayed correctly compared to the svg.
I was just wondering this too. However, it appears that Imagemagick might not be the best tool to do this.
Imagemagick is a "raster image processor," but SVG and EPS are vector formats. So using Imagemagick will cause those images to lose information as it has to convert from a vector format, to a raster format, and then back to vector. This probably explains why the contents of your image aren't correctly displayed.
Maybe consider using Inkscape to do this conversion using the following
# Works as of Version 0.92.4
inkscape ing.svg \
-E out.eps \
--export-ignore-filters \
--export-ps-level=3
where the -E flag is short for --export-eps to export EPS files.

What is the preferred way to convert various images, bitmap and vector, for use in a LaTeX and PDFLaTeX document?
There are many ways to do this, some make use of standard inclusions in the various LaTeX packages, others give better results.
You can include a PDF image directly into a LaTeX document if you want to produce your final output using pdflatex, but not if you want to produce a dvi file.
pdflatex can use PDF, PNG, and JPEG
latex/dvips can use PS, EPS
See more details:

I convert bitmaps into PNG, and vector graphics (e.g. SVG) into PDF. pdflatex understand both PNG and PDF.
If you have an image "as PDF", and you don't want to include it as pdf, you may want to extract the complete image data first with pdfimages. Other conversions may render the image only with reduced resolution.
My current preferred way is using bmeps and epstopdf included in MikTeX. For the generation of pdf and eps versions of a png.
In a file called convertimage.bat,
bmeps -p3 -c -e8f -tpng %1.png > %1.eps
epstopdf %1.eps
Use by including in the path and writing convertimage.bat filenameminusextension
Include in the documents using,
\begin{figure}[h]
\begin{center}
\includegraphics[scale=0.25]{path/to/fileminuxextension}
\caption{My caption here}
\label{somelabelforreference}
\end{center}
\end{figure}
I only use Encapsulated PostScript (.eps) figures (converting bitmaps with NetPBM first), since I always use dvips + ps2pdf anyway, and then I do \includegraphics{file}.
As John D. Cook says, your available image formats depend on whether you are using latex or pdflatex.
I find ImageMagick a useful tool for converting images between formats. Handles bitmap images, plus ps/pdf/eps (with ghostscript) and a zillion others. Available through apt, macports, etc.
I use a mac so I use GraphicConverter to load images and export as PDFs.
When I draw diagrams, I use Omnigraffle which lets me export as PDFs.
On windows I used to use Visio which supported EPSs which I also had no problems embedding.
The basic issues are that a) you want to handle raster and vector images differently and b) this introduces potential pitfalls.
The "right" thing to do depends a bit on your final output.
If your final output is going to be a .pdf file, and you don't need pstricks or anything else that these days you're probably better off just using pdflatex to directly produce the file.
In this case:
store all vector figures as .pdf
store all raster figures as .png (or jpeg if they were originally jpeg)
use graphicx package and \includegraphics{filename-without-suffix}
If you don't do the above, your raster figures will be converted to jpegs and may gain compression artifacts. png is the best bet if you can choose output.
If you are headed for .dvi file you're going to want .eps for everything. (You can gzip these files as long as you generate a bounding box file).
If you're careful you can do both. I store all vector figures as (compressed) .eps because there are a few things .pdf can't do that .eps can. I store all raster figures as .png. Using make, I can have temporary copies of these canonical versions generated on the fly for .dvi or .pdf output as needed.
Someone above pointed out the filename issue. You want to avoid "." in the file names, and avoid suffixes always in your latex file itself.
I always include images in PNG format.
If you compile your code with pdflatex, then you also can use the \includegraphics to include images in pdf (you have to include the package graphix
