White Edges

White Edges
I have made a couple pretty nice text images, for friends, and myself. Many times this text image will have a border and consequently a transparency along a corner of the image because they are not always perfectly rectangle.

The problem is the images keep saving with a fine white line at the corner's of my image.

How can I make this sharper so it doesnt have this white edge that stands out from the image?

RE: White Edges
I found a plug in with an option to smoothen the image called G'MIC, but for whatever reason I can't install it. It saves to my folder as a .par2 extension. Its in the Gimp registry. I am still learning the ~/.gimp-2.6
Ctrl+H
Drag and drop method (we will stick with the other thread on this topic)

Here are the pics

Around the edges you can see a little, but on my screen when the pics are clearly visible, these white edges are very noticeable. Even the second looks faint, it is quite apparent.

RE: White Edges
They are due to either a bad cutout which didn't take in account the anti-aliasing, or to a "bucket-fill" on the background.

This question spurred me into writing a short article on the subject of these pesky anti-aliasing pixels, so it's now all explained here: http://gimpforums.com/thread-proper-subj...d-painting

Happy reading Smile

RE: White Edges
OK, here be another one Ofnuts; I have created this new image and I have two strange malfunctions. This first one has a pixaltion, yet it is not on a transparent background as in the original post. Here is the image :-

[Image: Screenshotat2012-01-07011054.png]

I tried using the wand and setting it to Alpha channel. This is not going to work because the background is an image as well.

Here in the second malfunction is this new scratchy effect I am getting. This started happening more recently. It could be from adding all my plug -ins, incorrectly Sad If I change the opacity it goes away, but sometimes I dont need to change the opacity. This can be as much as turning it down one or points and it disappears, but reappears if I keep moving the dial :-

RE: White Edges
Too hard to guess without seeing the whole XCF (or at least an image cropped to the relevant areas, saved as XCF with all layers...) . And how did you produce the "IDID" letters?

RE: White Edges
Hmm, well the scratches in the second pic were after I edited the original and only saved that as jpeg. I do have the pixilated look still with the xcf file.

Here are the layers :-

A screenshot of the Layers dialog isn't an "image cropped to the relevant areas, saved as XCF with all layers".

Me in my mechanic shop: "I can't diagnose your strange noise in your car without doing a test drive"
You: "Of course. Here is a picture of the Licence plate".

In other words, I need your original image, or, if you don't want to post in on the net, that image reasonably cropped to the problematic part.

What the digimon thats what this post is

No?

Do you mean each layer needs its own screen shot of the image?

It's a screenshot, seen from the top layer with compositing applied.

I don't want a screenshot, I want the XCF. I want to be able to check pixel py pixel on every layer what the RGB and alpha-channel values are and what the opacity mode is. So it's either every layer saved as a PNG plus indication of any opacity modes, or the plain XCF.

However, you seem to be overloooking that instead of linking to pictures outside of GimpForums (photobucket or else) you can attach XCFs right here on GimpForums (just enter the "full edit" mode when posting, or hit the "preview" button if you are in the "quick edit" mode) (see below)

RE: White Edges
This is not meant as a joke, or meant to be rude at all, but what you are saying I am not sure how to do.

I have attached a new image and it is a perfect example of my issue. Hopefully this is what you are asking, but if it is not please understand. I am going to follow the instructions to the best of my abilities.

Thank you.

RE: White Edges
The full image is indeed what I wanted. However I don't see anything wrong with that one. I can't see any undue pixelization/aliasing at 100% zoom. Maybe I'm not looking at the right place. At what coordinate should I look?

Are you by any chance working on a bigger picture that you scale down? This can cause aliasing to show up...

RE: White Edges
Hmm, you know it must be my Gimp program. I adde dall those plug ins through Nautilus remember? I finally learned how to install them in crtl+H, but I already installed quite a few.

Here is the image I have.

The settings in the layers box is how far I have gotten.

I was just adjusted the duplicated text layer and changing the mode around a bit. This is what I have been getting. It only started last week.

I am installing a whole new OS on a new PC this week so I will have to reinstall Gimp on that anyways. My guess is anything saved in XCF can be saved and then reopened with the separate layers on a reinstalled version of Gimp?

It should be a very strange bug in a plugin to shift every other line in some tiles in the main program. I'm wondering if that could be a hardware problem (memory). Not very low level in the hardware since it shows up in screen captures...

Yes, if you save as XCF you get the separate layers on your other computers. When you save as XCF I see your layers on mine Smile XCF is the format to save your Gimp work. Accept no substitute.
