Re: [Gimp-user] How to draw a line? :(
Did you read the actual straight line tutorial? It's here: http://www.gimp.org/tutorials/Straight_Line/ It details exactly what to do, step-by-step. Marco On May 12, 2006, at 9:02 PM, Simon Roberts wrote: I'm feeling particularly useless today, I'm pretty much a total beginner with GIMP, but I can't believe this is as hard as I seem to be making it. I want to draw a straight line. I'm using Gimp 2.2.4 I try the paintbrush, I have a color selected, and I can draw a squiggly line. The help says that holding shift down will make all these tools constrained to straight lines, but mine doensn't draw anything. It looks like it's trying to do measuement or something. I try the path tool (which I can't claim to understand) and then try to "stroke" the path. I get polygons while I'm messing about, I can also get curves, but I don't seem to be able to get an actual line that stays on the page. What I _want_ is a straight line, constrained to horizontal or vertical, drawn with the caligraphic brush (so it has a chiselled end) and using the "fade out" option, so it disappears smoothly over a distance.

Re: [Gimp-user] Is this compatible?
On Oct 7, 2006, at 7:25 PM, Chris Mohler wrote: Apologies - forgot to "reply-all" My advice would be to save your files in TIFF format. If you enable LZW compression, the file size will be significantly reduced without losing quality (unlike JPEG, and to some degree PNG). PNG is just as lossless as TIFF with LZW compression. There are ways of lossily compressing PNGs but they are non-standard and GIMP does not implement them as far as I know. Either will suffice in this case as photoshop reads both, though its support for PNG in certain situations (mostly having to do with 16 bits per channel images) is sub-par. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

If you save an RGB32 image as an indexed or grayscale PNG then yes, you've lost information. But that is inherent to grayscale and indexed images. You should have saved that as an RGB32 image, which PNG fully supports. In this case it isn't PNG throwing data away (like JPEG does), but the image editor (GIMP) converting to indexed/grayscale and then saving that. Indexed and grayscale modes in PNG are just as lossless as its non-indexed modes. However like I said there are methods of tuning the PNG's compression to be lossy, and yet still be PNG-compatible. No image editors that I know of implement these methods, however.

Uh, no. Think of that person in the mirror as someone else for a bit and forget the mirror is even there. If you were raising your right hand, then that person would be raising his left hand. Maybe it'd be even clearer if you stood across from someone and both raised your right hands. You'd find the other person's hand would be on your left side. Mirrors flip left and right. Always have, always will. Any text held up to a mirror would come out the same was as were it flipped.

Re: [Gimp-user] [Q] Resizing a PNG makes it BIGGER!
My guess is that this is because of the interpolation when resampling. Makes it less easily compressable. (Notice the 'anti-aliased' edges in the resized picture?)

If you want an alpha channel in your png, just use save as a png without flattening. It'll ask you to merge the visible layers for the export because png can't handle them, and save a png just like you want it to: with alpha channel.

First off -- unless you mean you want to see through parts of an image entirely, you mean translucency. Transparent -> invisible; translucent -> see-through. The alpha channel is basically a channel just like red, green, and blue, except that it determines the translucency of the pixel, instead of the colour. > what does that have to do with "alpha"?

I think 9 is the highest possible in zlib. Anyway, if no one has said it yet, this is most probably caused by you scaling the image with resampling turned on. This makes images less easy to compress when using the types of compression that PNG and such use. How about you put the images online somewhere so we can be sure of this?

If I understand what you want correctly, this is what you should do: Add a layer mask to the top layer (right-click; add layer mask) Click the layer mask preview (next to the layer preview) to make sure it's selected. For some unholy reason the border that shows it's selected is white here, but it's there. Select the gradient tool, and proceed to make a black to white gradient. Because the layer mask was selected, instead of a black/white gradient you'll see the layer become transparent where the layer mask is black, and translucent where it's gray. The white area will be opaque. Once again, this is my interpretation of what you want to achieve. I could be All Wrong.
