How to convert eps files to png files with maintaining names?

In some folder on Linux I have got files *.eps and I would like to convert them into *.png with maintaining names, e.g.: ball.eps to ball.png. I tried to do:

but the result wasn’t satisfied. To do that I need to write some simple script maybe in Python or bash, so how can I take the files name from folder, e.g. in Python? Thanks.

Try the following script:

Hope it should work for you.

1. for file in *.eps gives the list of all files with .eps extension
2. filename=$(basename «$file») gives the original name of the file
3. filename=$ remove the extension .eps
4. convert $file $filename.png convert file to .png extension

edit: if you want the filenames to be the same, I don’t even think that you need a loop. You can do:

mogrify is like convert but it modifies files in-place, so you need to back them up elsewhere before you do this if you don’t want to lose the originals.

Using a loop, you can do this in bash:

The wildcard * in your attempt will expand to the list of all the files everywhere you use it, which isn’t what you want. By using a loop variable «$f» instead you’re only working with one file at a time.

You can also avoid calling basename and use:

This cuts off the eps from the end of the filename and adds png to it.

Since I landed here while looking for a way to fix convert: not authorized without loosening the security policy for the entire system, I might as well present some improvements to @vaibhav-jain’s answer.

First, if you’re rasterizing EPS to PNG, here’s how to skip ImageMagic and go straight to Ghostscript:

• -dSAFER puts Ghostscript in a sandboxed mode where Postscript code can only interact with the files you specified on the command line. (Yes, Postscript is turing-complete.)
• -dEPSCrop asks Ghostscript to not pad it out to the size of a printable page. (details)
• If you’re rasterizing EPS, you probably don’t want the default of 72 DPI, so -r300 specifies 300 DPI. (details)
• -sDEVICE is how you pick the output format (See the Devices section of the manual for other choices.)
• -o is a shorthand for -dBATCH -dNOPAUSE -sOutputFile= (details)

As for the other changes:

• It’s unnecessary to strip off the leading path unless you’re in a situation where you don’t want the output files to go into the same folder as the input ones. in that case, however, you can replace $(basename «$file») with $ (strip characters up to and including last / ) to stick to shell built-ins.
• If you’re using Zsh and want to write a one-off one-liner, Zsh allows nesting substitutions, so $<$%.*> is valid.
• Just as a matter of style, I prefer for . ; do over putting do on its own line.
• Nothing in the script requires bash, so use #!/bin/sh in such situations and you’ll get a lighter runtime environment (dash) on Debian-based systems and be compatible with BSDs that don’t install a /bin/bash by default.

Image format conversion from terminal?

Is there any way to convert image formats from Ubuntu terminal?

Particularly from eps to png/jpg or to any other formats.

You can use the imagemagick command line tool

You can use it like this:

For anyone who lands here trying to figure out how to work around ImageMagic’s convert: not authorized without reverting the change that was made to the system-wide security policy to close a vulnerability, here’s how to rasterize EPS files by calling Ghostscript directly:

• -dSAFER puts Ghostscript in a sandboxed mode where Postscript code can only interact with the files you specified on the command line. (Yes, the parts of EPS, PS, and PDF files that define the page contents are in a turing-complete programming language.)
• -DBATCH causes it to quit when it reaches the end of the input file, rather than switching to an interactive PostScript prompt.
• -dNOPAUSE prevents it from prompting to continue after each page
• -dEPSCrop asks for the rendered output to be cropped to the bounding box of the drawing rather than padded out to the declared page size (See the manual for details.)
• The -r600 specifies the DPI you want to render at
• The -sDEVICE specifies the output format (See the Devices section of the manual for other choices.)

UPDATE: I’ve since learned that -o foo.png is a cleaner, easier-to-remember shorthand for -dBATCH -dNOPAUSE -sOutputFile=foo.png so the better command would be this:

The manual also mentions that, some day, they eventually hope to be able to make -dSAFER the default though, given backwards compatibility needs, who knows if that will ever happen.

How to convert an .eps file into a .png in Python 3.6

With Python turtle I’m trying to save the canvas as a png. I’ve researched it and found a way to save it as an eps file without any modules, but I’m finding it hard to convert the eps file into a png.

Is there a way to convert eps to png without downloading another module? If not can someone tell me more about ImageMagick, because I have looked at it, but I’m confused how to use it? I’ve also seen it being linked to linux and is it outdated?

If not converting eps to png, is there a even simpler way to save the canvas as a png?

From the link you show, there is this Imagemagick command:

Most EPS files are vector images. They have no physical size in pixels, since it a vector drawing with commands that describe how to draw each object. It is not a raster image containing pixels and does not have any particular pixel set of dimensions.

So with vector files, you set the printing density to tell Imagemagick (which passes it off to Ghostscript to do the rasterizing work) to convert the vector data to raster data and then save it as a raster format output image. Nominal density is 72 dpi (sometimes 92 or 96). So if you use -density 288 with the following command:

It would result in an image that is 4 times larger in each dimension than if you just did

which for default dpi of 72 would be the same as

Note that 72*4=288.

Now you have a large high quality raster png, especially if the eps file was line drawing with thin lines like blue-prints.

However if that is too large and you want to reduce it back to its nominal size by 1/4, you could do (note 1/4 = 25%)

This process is sometimes called supersampling and would produce a better looking result than just doing

In the original command, they decide to get a high quality raster image and just resize to 1024×1024.

So you can resize to any size you want after producing a high definition raster image from the EPS vector image.

The larger the density you use, the higher the quality will be in the PNG, but it will take longer to process. So you have to trade time vs quality and pick the smallest density that produces good enough quality in a reasonable amount of time.

I do not know if Python Wand supports setting the density or if it supports reading PDF file, which requires Ghostscript. But you can use Python Subprocess module to make a call to an Imagemagick command line. See https://www.imagemagick.org/discourse-server/viewtopic.php?f=4&t=32920

I’ve been having problems with ImageMagick having had its security policy changed so it can’t interact with Ghostscript. (for good reason. but it’s questionable that it doesn’t allow you to locally override the default policy so web apps can be protected while whitelisted uses can still work.)

For anyone else slamming into convert: not authorized , here’s how to invoke Ghostscript directly:

• -dSAFER puts Ghostscript into sandboxed mode so you can interpret untrusted Postscript. (It should be default, but backwards compatibility.)
• -dEPSCrop asks Ghostscript to not pad it out to the size of a printable page. (details)
• ImageMagick’s -density 300 becomes -r300 when it invokes Ghostscript. (details)
• -sDEVICE is how you set the output format (See the Devices section of the manual for other choices.)
• -o is a shorthand for -dBATCH -dNOPAUSE -sOutputFile= (details)

You could then use ImageMagick’s mogrify command to resize it to fit exact pixel dimensions:

( mogrify is like convert but replaces the input file rather than writing to a new file.)

UPDATE: In hindsight, I should have checked whether Pillow supported EPS before posting that first answer.

The native Python solution would be to use Pillow’s support for invoking Ghostscript (like ImageMagick in that respect, but with a native Python API).

However, Pillow’s docs don’t explain how they arrive at a size in pixels and only take an optional multiplier ( scale ) for the default size rather than an absolute DPI value.

If that doesn’t bother you, and you’ve got both Pillow and Ghostscript installed, here’s how to do it without ImageMagick:
