[Gimp-user] GIMP and Tablets ...endless story, I expect.
Hello, I have an Aiptek6000U tablet, for which I finally got the kernel driver working. evtest reports what seems to be correct.

I configured the tablet through Edit-Preferences-Input Devices-Configure Extended Input devices-Device: Aiptek, Mode: Screen, Axes: X-1, Y-2, Pressure-3. Xtilt-none, Ytilt-none. Moving the Stylus cursor and pressure works. Now to the big BUT: To have the stylus drawing I have to press the lower button on it. This works *sometimes*. And there is no way to stop drawing again. Plus, switching tools is not possible, GIMP doesn't react to the keyboard while the stylus is in use. What I'm doing wrong? How is it supposed to work? Kind regards Jan -- gerard82 (via gimpusers.com) If you use KDE as a desktop you might wanna try kde-misc/wacomtablet. Despite it's name it supports quite a few graphic tablets and some Aiptek models among them.

[Gimp-user] Web development question?
Hey all. I would hope this might get some responses... I just today saved my first png file. In doing so Gimp came up with a choice box, as to parameters you can choose or not: Interlacing (Adam7) (whatever that is) Save background color Save gamma Save layer offset Save resolution Save creation time Can anyone tell me which of these options they use? What does Adam7 mean? I am looking to create some web pages with drupal. Can anyone tell me their process they use to do a similar goal? (With drupal or WP, etc.) What I'm thinking is that certain of the settings are compatible or not with the blogging engine or not? do you use png or jpeg?, etc. Just wondering. Trying to get up to speed. Thanks so much. Dan ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

PNG is quite useful for some effects. Say I wanted a div element to
have a gradient background - I could create a new image that's 1px
wide by the height of my div, add a gradient, export as PNG. Then the
css would be something like:
div { background: url(/path/to/png/file) repeat-x }
..and all divs would have a gradient background, using one tiny file
(and even IE6 will comply). Quite useful for things like faux drop
shadows, rounded corners, etc. too (but newer CSS techniques are
arguably better/easier).
My general rule is: photograph - JPEG, icon/effect -PNG. As with
every rule, there are exceptions ;)
Anyhoo, there are tons of uses for PNG in web design. Check out a
Joomla template sometime - most of those do a crazy amount of styling
using PNG files.

Very useful information. I'm in the habit of just pressing enter twice to export. :) I've always wondered what this stuff does, so this has been an interesting read. -Stefan Maerz ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

(With drupal or WP, etc.) What I'm thinking is that certain of the settings are compatible or not with the blogging engine or not? do you use png or jpeg?, etc. I usually use jpg format for nearly all web images, because comparable images saved in png normally have larger file sizes. The most potentially interesting feature of png is that it saves transparency, and *nearly* all web browsers now in use understand how to display png images with transparent areas. If you need a transparent background, and you need higher resolution or better scalability than the gif format provides, png might be your answer. Others may know uses for png that I am not aware of, but so far I have found no use for it in web design. In re transparency, most of the time you will not need it. If you load the page under construction in a web browser and use the eyedropperin the GIMP foreground/background color tool, you can set the exact value to make an opaque part of your image match the page background exactly. As a point of difference :) I find myself tending to save the majority of my images (in terms of developing the site - stripes, decorations, non-content stuff) as PNGs. Firstly, I make most of my images from scratch using minimal numbers of colours to minimise load time anyway so the PNG is almost invariably a lighter weight option. For larger pieces such as banners, photos, avatars, artwork, anything with lots of different colours, I would probably use JPG. On the transparency front, I find PNG a huge benefit over GIF. The obvious example is for logos/decorative images - GIFs do not have alpha transparency, a major issue for any shape other than a rectangle. Another benefit to using PNGs in websites is being able to make interesting and lightweight blocks of colour combinations using repeat-xy backgrounds of semi-transparent images. eg a 1px black image at 20% transparency, etc. I think the last time I saved anything in GIF was for a favicon...

But the moment I stop writing alternate style sheets for it, I just know my next client will be running it in Win2k and asking me why the pages are all broken and stuff. :o) There is a minor but sound reason for using png rather than jpg in many of these cases - the fact that png is lossless. It does result in somewhat larger files, but if the specific image wants to be compressed to an indexed-mode jpg for file size reasons, a png background is I believe somewhat less likely to create artifacts - or so it seems to me. I did not know that jpg had an indexed mode. I knew I would be getting some interesting feedback when I posted that answer. I have been doing this junk for so long that I developed an automatic habit of anti-aliasing transparent gif images by hand as per my earlier comments. And yes, it is time to abandon that and just use png images. Yay! :o) Steve ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

It just seems to me if one exports a GIMP image in indexed mode to jpg the file comes out smaller. Haven't run extensive tests on that, though. GIMP actually transforms back to RGB before going to jpg (asking if that's what you want first). So YMMV.
