Warn when exporting a bitmap with an invalid file extension.

[insaner]

i was running into strange errors after exporting some images from inkscape directly to jpg files (i usually do png files, but the requester of the image allows only jpg).. and when i opened the image in gimp and resaved it with another filename and then did a diff, i realized the one generated by inkscape was actually a png file but with a jpg extension..

dont know if inkscape handles jpg, but if it does, its not doing it during export, and if it doesnt, there should be some sort of warning if you choose a different extension (which usually is accompanied by the expectation that the file will be of that format.. you know, like what happens in gimp..)

thanks

You can only export to PNG (JPG is not currently supported).
Note that in the trunk version, the File>Export Bitmap entry was renamed File>Export PNG Image to prevent confusion.

See Bug #171390 "Extended Raster export support please".

Changing status, and setting importance to wishlist for the file extension handling (warning, automatic replacement...).

yeah i think a warning while Bug #171390 is still not resolved would be the best course of action for the time being.. and even after.. since unknown file extensions are bound to be tried by oblivious users (such as myself).. you can always support 21 image filetypes, and someone is going to want to try to save in filetype #22..

In 0.48 the .png is added auto to all exports. It prevent for example overwrite other files like current SVG.

In 0.91 on Windows 7, Inkscape will allow you to export a file in PNG format but with no extension. I think it should automatically add the extension to the end of the given filename like many other programs do.

@JazzyNico - It's not a warning, but effectively prevents from exporting with a wrong file ending: Can we close this report (for milestone 0.92)?

~suv - Confirmed, the report can be considered fixed.
Thanks!
