Convert-to jpg wmf on Linux, resolution issue.

Hello, first of all, I don’t speak English very well, I apologize if I make any mistake writing.

I am developing a website that import xlsx files and gets all the images. Some xlsx are generated by a third party software in windows and when images are extracted I get files in wmf format.

For example I want to convert a wmf image (136x77 px) to jpg and I use the command:

libreoffice --headless --convert-to jpg uploads/temp/image.wmf --outdir uploads/converted/

As result I get a jpg image (794x1123 px) with white background and the tiny wmf img centered.

How do I convert to jpg keeping size of original wmf?

The xlsx file has inside many images with different sizes.

Thank you!
Best regards,
Edu.-

Try using dedicated image processing utilities for the conversion, like ImageMagick.

Hi Mike, is a shared web hosting, I get libreoffice comand enabled. I will try to test with command convert. Thank you.

I know LO has many issues with that kind of image (EMF-WMF); here the meta-bug report.
Thus, I have reason to believe this is a bug.

Anyway, I am the same way as @Mike2 Kanganski: LO is the wrong app to handle with images;
use other tools like GIMP, imagemagick or online services, …
