Prevent image conversion

maff · 06-08-2023, 11:04 AM

Hello

As part of our workflow we convert our EPUB files to Word docx to send to our reviewers for updating.

We have been using Calibre to do this. However, we changed our image format to SVG last year and now the text in the images appears in single lines rather than in text boxes, when converting to DOCX.

It looks like Calibre converts the SVG images to PNG during the conversion process.

Is there a way to prevent Calibre from converting images?

I have attached the EPUB file, the converted DOCX file, a screen shot showing the problem image in Word and a copy of the original SVG file.

Here is the conversion log:

Spoiler:

I did not change any of the conversion options.

Many thanks

Does Word even support SVG? At the time I wrote the DOCX output plugin it definitely didnt.

I was able to import that SVG into a blank DOCX file. As you said, it probably didn't when you DOCX output plugin.

LO Writer supports SVG, don't know since when or what input formats.
MS Word (don't know since which version & not tried my 2007) can't insert an SVG file, but at least on Word 2019, according to various sources inc MS, you can copy/paste SVG from Inkscape via clipboard.
This suggests copy/paste SVG into Word 2007 works, because there is a quality setting.

But as to what is done when you save / load a docx is another story. I'm not inclined to research it as I run Linux & LO, though I have some Windows boxes and XP, Win7 & Win10 on VMs and Word 2003 on WINE. Not sure which install has the MS Word 2007.

Edit:
Perhaps even when you copy/paste, saving the docx rasterises it, otherwise why would there be a quality setting?

It's a fairly recent addition, IIRC Office 2019.

Can someone attach a docx file with an embedded svg, I only have Word 2008 (last I can get working with WINE).

Here you go.

Well I added support it was fairly trivial to do, but I have no way to test it. Attached here is a docx to docx conversion of BetterRed's test file using the new code. Try it in word and see.

Both open in LO Writer 7.4x, though I can't tell if raster or vector. The t.docx properties have image.png as name and doc1.docx is empty.

my Word 2003 on WINE has no docx plugin. MS removed that patch/update from their site years ago (released some time in 2008?)

I thought my 2002/XP had a docx plugin, but not on the VM. Must be on a box somewhere. XP no longer connects to my server, so I'll have to put test files on a USB stick. The Win10 VM has no MS Office (possibly, but Start & Search is so "broken" on Win10, who knows?) and the Win7 VM has WordXP/2002, so the Word 2007 must be on a box somewhere.

LO doesnt support svg as far as i know. So it will use the raster rendering. IIRC the raster rendering has the far tusk not rendered well.

Word is coming up saying I can only view it. The permissions need to be fixed.

kovidgoyal · 06-09-2023, 07:24 AM

You can also try resizing the image it will not show jaggies if its svg when expanded.

What permissions, adding svg support didnt change any permissions. Presumably you downloaded the file as a readonly?

I downloaded the file and it opened in Word without any issues, the image displays perfectly.

Does version 6.20 have the support for SVG added?

Jon, Word is rightfully blocking the t.docx from edit because it came from the 'Net. You can click the Allow Edit button in Word or check the Unblock checkbox in the file's property box. Standard Windows behaviour.
