Novice gimp user

I had a previous version of gimp along with some plugin i assume

I could open 10 images as layers, crop and then export all layers. I cannot seem to remember what plugin that was if it even was a plugin. The only thing i remember is that the output folder was always in system 32

Any clue what it might have been?

Have a printer requesting 8.5"x11", 300 dpi, 1/8" bleed.

Have a GIMP doc at 2625x3375 and 300 ppi. Printer says it's coming up as wrong size and 72 dpi. 

Am I missing something or are ppi and dpi not comparable?

Hi, I am working on an icon theme for Ubuntu. It is based on Yaru ( the default icon theme ). The difficult part is that there are many sizes of PNGs that Yaru ask for each image.

I was wondering if there can be some script or so that can resize an image into all Yaru-compatible icon sizes?  Something like we have for iconify.

   

An image needs to be in 256, 48, 3, 24, 22, 16 and 8 sizes for the icon theme to work properly.

For now, I am using a 256x256 for all. It causes burr ing at edges, in some cases, info windows show a big image than a small icon due to the parent image size.

Any help would be great. Thanks.

Wondering if someone could give me a little help.  I used an stl i modeled to create a grayscale heightmap for CNC carving but the outer edges are too steep (see red circle).


I figured I could fix this by applying a gradient around the boundary selection of the image in gIMP to soften the edge between my greyscale image and the black background.

After some google searching I saw there was a tutorial for gradient border select, and the image looks to be similar to the affect I'm trying to achieve, but it was on gimplearn, which seems to no longer exist.

I've included pictures of the greyscale image, what the result is in my carving software, and a picture of the effect i'm trying to achieve.

Any and all help appreciated!

Edit: seems most image hosting service are blocked on my work's network with the exception of tiny pic, which doesn't seem to load into the post correctly, I have included the links below.

Hey everyone, I'm new to GIMP and I usually just google my questions and get my answers pretty quickly, however, this issue I haven't found any answers for and its one that affects the functionality of my work process. 

I usually resize covers for paperbacks and hardcovers for Amazon and they have precise measurements for what they want as the covers. 

Usually on photoshop, I could get the measurement down to the third decimal place without any issues, this is on my PC experience. However, I'm now on a Mac and I'm using GIMP and when I try to do the same for the resize, once I set it and leave the numbers, it rounds up, so 13.025 inches becomes 13.030 inches and 9.917 inches becomes 9.920 inches. 

This won't do as Amazon would come back with an error that the size is still unmatched. 

How do I ensure that it stays at the exact numbers I selected?

Any assistance would be most appreciated. Enjoying GIMP as an alternative to Photoshop at the moment and want to continue to do so.

For a school project, I need to make a linear gradient go from a color to transparent. I'm no stranger to using Gimp and I know the steps I need to take in order to achieve such an effect but a strange issue has been occurring. There's this weird dithering effect on the side that is supposed to be transparent.

I already unchecked the dithering option in the gradient tools but the effect still persists. I've looked up tutorials but none really seem to have this issue. I've even reinstalled Gimp but nothings changed. Does anyone have any idea of what's going on or what I'm doing wrong?

PROBLEM STATEMENT
The coordinates of a fixed point in a drawing change after i use the move tool to move the drawing around so i can see other features and then return to the fixed point. The error is on the order of 300 on the x axis and 50 on the y axis and varies for each test. If I measure and move a short distance and return, I am within user error of about +- 2 units. 

CONTEXT
The image in GIMP is a scanned image of an architecture drawing.

ASSUMPTION
1) when an image is loaded into GIMP, the coordinate system of GIMP is aligned with the scanned data of the image. Hence The coordinates of any one
    point in the image should always be the same.
2) Using the GIMP Move tool, the tool moves only the viewer, not the drawing and its cooordinate system.
3) If i quit the drawing without making any changes in it, the coordinates of a fixed point within the image should have the exact same coordinates when
    the image is opened up once again. By exact i mean as exact as the user can replicate where he is measuring. I find +- 5 units acceptable variation.
    My errors are at least 300 units.

Please straighten out my misconceptions so that i can change what i am doing so that i can scan and extract coordinates with reliability and repeatability.

thank you

Hi All,
I wonder if someone could point me in the direction of a setting or let me know what I am doing wrong.

After making a selection I want to clear the background. I invert the selection and press the delete key to clear the selection. The problem I'm having is that it is also fading a little from outside of the (inverted) selection. I.E. fading a little from the part I want to keep.

Here is my process. I foreground select the object. Create a layer mask for the selection. Add a white background layer. Select object layer. Invert selection (because the layer mask has carried over some areas I don't want and were not selected. The press delete.

I'm sure it is just a setting but I can't work out which one.

Many thanks in advance for any help.

I am trying to create an svg path of an infinity symbol, but i can't seem to be able to do that,
every time i go to Select->To Path it creates multiple paths two for the outline and one for the holes.

i want to have it be just a single straight line.

i have attached what it looks like, as you can see its multiple items and not just a singular straight line.
