Hi. :) ...
- Add jpeg export; for the moment I open gimp to export from png to jpeg.
Feature does not exist, but the reasoning, as far as I've heard are these:
1. JPEG is a bad format to output vector to raster because it uses lossy compression, and introduces artifacts along the otherwise pristine pixel edge of vector shapes. This gets worse the more compression you use. 2. JPEG is also a very old format that is only currently used because of popularity. 3. JPEG should not continue to be popular, and we want to try and push users to use better formats.
Now, as a career graphic designer who uses Inkscape all the time, I still use GIMP and scripts to convert exported pngs to jpegs.
Now why would I make such a horrible mistake, knowing full well of the limitations of JPEG?
1. Clients ask for it, and their software sometimes demands it. - If you don't give your clients what they ask for, they don't tend to pay you, or they do pay you, but then go somewhere else because you're a hassle to work with. 2. png compression is wonderful for vector rasterization, and absolutely terrible for detailed graphics. - Inkscape handles a mix of vector and raster, which is a large portion of what makes it an excellent drawing and graphics tool, thus there is no reason to artificially assume quality is preferred over file size. Often for web graphics, it is essential to get the file size down to be as small as possible. png can do it, but only for simple graphics. Since details must be preserved for the format to be lossless, any detail can not be compressed. 3. I dislike when software makes me go to other software to get what I need, when it could easily provide it. I don't require babysitting in this fashion. Most professional artists will feel the same way. 4. I understand the decision, but I disagree with it. We are not popular enough to push the issue, and it's a usability crutch for everyone who needs jpegs. I think a warning in the jpeg export dialog would be sufficient to warn people away. As it stands, it does not keep people from using jpegs, it just forces them use other software to do it, which wastes time, and is a major kink in Inkscape related graphics workflows.
That said, I usually save exported pngs anyway, but I don't do this because Inkscape has enlightened me. Indeed, no reason at all is given in the software for only allowing png export. I think enabling jpeg export gives us a great place to enlighten people about why they should prefer png to jpeg, then let them decide.
In the export to jpeg dialog, it could include this disclaimer in RED: You have chosen jpeg as an output format. JPEG is a lossy format that loses picture quality, and introduces nasty compression artefacts and kicks puppies for fun in it's spare time. We recommend export to png for lossless compression, and a better world, with happy puppies.
My 2p. ;) -C
- Add size templates for biggest screen size, one by ratio: 4:3, 5:4,
16:9, etc.
Do you mean ‘predefined sizes’? Well, you're right, I don't see anyone having a standard screen resolution.
- in addition a feature to export to several sizes from the size template
with the same ratio, with check box to select which one we want.
You probably mean ‘radio buttons’. A combobox would better fit me…
What do you think about these features ?
About JPEG and other raster exports, I also wonder why they're not allowed; I suppose it's not the purpose of the project… Actually, I think JPEG is a quite weird choice for vector graphics.
Concerning the predefined sizes… Looking at the current long list, my first idea would be to organize it with size categories so the one we want would be really easy to find; currently, I don't see why it would be helpful to have your screen resolution in a list when you can just type the values. Having those categories, a category for screen resolutions could be nice.
Concerning the ‘ratio export’, I don't think it's so hard either to type just one of the dimensions you want…
Is it the right place to talk about that and to do this kind of proposal?
The usual place is the bug tracker on Launchpad but it also works here.
Thx and sry for my en.
