Window Size Configuration (either default or not) Doesn't Seem to Work

[fededamian]

Hello maaaaz, and thanks again for this great tool and the support. Today I am reporting an issue that seems pretty obvious to me, so I don't know if it happens under certain conditions in my environments, although I tested it both on Linux and Mac. Let me know if I can provide more data than the following:

• Issue: Output screenshots have the content of the whole page, resulting in really long images, even though the default length should be 800 px and also when using the --window-size argument.
• Tested Version: webscreenshot 2.8 (but it happened with older versions too)
• Tested OS: Linux and Mac
• Reproduction steps on Linux: Run the following command and check the output image has more than 360 pixels on length.

python3 webscreenshot.py --no-xserver -r phantomjs -w 1 --window-size 640,360 -o ~ https://www.apple.com/mx/mac/

Hello @fededamian,

Thanks your support !

Indeed that bug seems to be trivial:

• But I'm just using the viewportsize option in PhantomJS
• This option seems to be bugged : https://stackoverflow.com/questions/13390859/viewportsize-seems-not-to-work-with-phantomjs

Could you try with another renderer ?

Thanks for the answer @maaaaz ,

Based on the README, I guess the other renderers have bigger issues than this one (no support for sites with invalid certs or no support for concurrency), so I think I'll stick with phantomjs and maybe add some post-processing of the image after I grab it.

That is a good idea, I guess you can do it with imagemagick

[fededamian]

I was able to achieve this goal by using the following imagemagick command (if the output of webscreenshot is a picture with the filename image.png):

convert image.png -crop 640x480+0+0 +repage -background black -extent 640x480+0+0 image.png

Which either crops or enlarges the image to the desired resolution.
