Posted: Tue Aug 11, 2009 7:32 am Post subject: vector graphics in NeoOffice |
|
I recall something about NeoOffice automatically converting vector graphics to bitmaps.
What I do not remember is if this is done for vector graphics on import, or when they get printed and/or exported.
Could someone enlighten me?
best wishes,

When you import a vector graphics format into NeoOffice, its underlying OpenOffice.org code imports it into a list of internal vector drawing commands. When you save the image, the underlying OpenOffice.org code will convert the internal vector drawing commands back into the image format that you are exporting to.
Where the imported image gets converted to bitmaps is when you copy the image. At that point, the underlying OpenOffice.org code creates a bitmap by executing the internal vector drawing commands and then hands that bitmap to the custom NeoOffice copy and paste code.
Hope that helps,

Indeed it helps.
So the bottom line is that you do not lose fidelity importing or keeping the image in your document, but you end up with a bitmap if you take it out of the document to somewhere else.
Good to know.
Thanks,

Yes, you do not lose fidelity. But, you still may see distortion when importing due to the inability of the OpenOffice.org code to properly interpret and match the images file format to internal vector commands. You really can see this with text size and kerning when importing PICT vector images.

One wonders why they keep maintaining that instead of going for something like cairo..
Or am I oversimplifying things, other than that ripping out code and replacing it is a tricky job?

Cairo is really for drawing things to the screen, rather than importing verctor graphics.
Anyway, when you create an application that supports editing vector graphics, you're always going to have to translate "other" vector formats into your native format to edit them. Depending on how "close" your native format is to the format you're importing, you may have more or less fidelity loss. E.g., Illustrator is good with PDF, since PDF and AI are closely related, but Illustrator does a lousy job with SVG, since it's rather different.
It's no different than with .doc and .odt
