GIMP :: Wikipedia / Easily Generate Large Custom Palettes?
Sep 29, 2012
i would like to expand on the Floyd-Steinberg dithered palette examples on this Wikipedia page.
[URL]
Is there a way to tell GIMP to programmatically generate a 6-bit, 9-bit, or 12-bit color palette?
All the dithered examples you see were created by me a few years back, by individually picking grays/colors to construct a custom palette in GIMP, then translating the original 24-bit parrot/color bars down to the custom palette.
For example the 8-color Floyd-Steinberg dithered parrot and color bars, on the Wikimedia Commons. GIMP does an excellent job of making these, and if you squint at it or look at it from a distance, it looks full-color:
Sure, I'll manually create a 16-grays palette or an 8-color 3-bit color palette, but it starts to get intimidating to make a 64-color, or 512-color, or 4096-color palette by individually picking each color, one at a time.
Also, I do not see how to generate the non-regular palettes without a lot of manual custom color picking:

I am trying to generate A4 tiles of a large banner (13m x 3m).
In the layout mode, I can't seem to get the image size to be set at 100%. If I manually set the image size to 100% and click on apply, this drops back to 38%. 38% is the highest it seems accept.
Is this a limitation with CorelDraw? Is there a way around this?

In Inkscape, you can select multiple objects by simply using the Selecttool and putting a box around the objects. I unwittingly did the samething in Gimp. I chose the Select tool (R) and selected several images inone column. I thought, that I would see all the boxed-in layers selectedfor easy duplication, but nope.
So how can I quickly/easily select a box-full of layers at once, a laInkscape?

I am trying to edit a custom palette externally and have successfully done it in the past but now Draw is "breaking" my new palette.
I created a new palette within Corel Draw and added a single color. This is to create the XML file and generate a unique GUID. I can open and the close this palette with no issues. I can add colors via Draw with no issues. I then close Draw. I then open the file with a text editor (NotePad) and add the code for my new colors (pulled from a spread sheet). My code matches the code in the Draw-generated palette color. It also matches the code from another palette I successfully created over a year ago. The file saves just fine and can be reopened in the text editor. I then reopen Draw but my palette name is no longer in the palette list. Then if I manually try and add the palette by opening it, it opens but strips all colors. Then if I open the XML file with the text editor, the GUID is now all zeros and all colors have been stripped from the file. I have tried rebuilding the workspace and rebooting the PC but neither option seems to work.
PS here is a sample line of code for one of the colors I am trying to add.
"<color
cs="RGB" name="RLM00 Wasserhell"
tints="0.980392156862745,0.968627450980392,0.945098039215686"/>"

I was wondering about custom color swatch formats. Specifically in an ancient version of Photoshop (like 3.5) in addition to the preset swatches, there used to be a blank "scratch pad" type palette feature where you could put colors and smoosh them around just like a real artists palette then pick colors from there....is there anyway to do this in Photoshop 7 without creating a separated doc?
Also, you used to be able to create a swatch palette based on the colors in a given image by going to mode>indexed color ....that doesn't seem to be working for me...

I am trying to setup some palettes to use at work and am using blocks to do so. What I've found is that my palettes work if I have left the blocks in place in the file in which I am creating the palettes. However, if I have deleted the blocks from the file, the blocks in the paletette will not work. Is this normal or is there something deeper?

I use ACA 2012 on two seperate computers and would like to be able to have all my custom tool palettes, blocks, customizations, etc.. to migrate to both computers. I.e. I add a new tool to a tool palette on one computer and then when I'm working on second computer that new tool appears in palette in correct location. I would think the easist way to do this would to be to share the location of the tool palettes, customization files, etc.. at a common place (network share) but am unable to find all the files and settings to do this.

I have a custom tool palette all made up, it has three palette sets and 8-12 palettes per set.
Now, is it necessary to add the palette sets and palettes to the content browser before sharing the .atc file around the office? Also, once added to the content browser, I cannot change the properties of a block e.g. scale, layer, rotation prompt etc..

I have a custom palette set on two machines. If I save a file on one and then open it on the other, the second machine does not recognize the custom colors and leaves the object blank. I can click on the palette and correct this but can I set it so that the colors will load correctly when I open the files.

So I am trying to create a TP that has a few commands on it... the problem is I dont know where to start in order to make everything available to the others on my network...
I have created a new GROUP, dragged a palette into that group, made my commands, and they work on my PC... but how do I get them all so everone can see them. Exporting the "command tool samples" and importing it as "My layers" works, but the name is still command tool samples and breaks the actual command tool samples...

I've made some custom tool palettes that are on the network. I just have them pathed in the options, and set up as a group for users to access. Civil 3D is real sluggish when it comes to using these, and switching between the tabs, and trying to load them up. But Vanilla AutoCAD loads them and switches between tabs no problem. Is there a variable specific to C3D that needs to change to make it work more like it does in Vanilla AutoCAD?

I'm using Corel Draw X5 and I can't figure out how to add or edit colours in the CMYK (default) Custom Colour Palette. In X3 and earlier versions it was quite easy to add new colours and edit existing ones. I would also like to know how to move the order of the colours in the palette so that I can put one a custom colour near the top.
FYI I would like make these changes to the master / global CMYK palette, not just the one for a specific document palette.

When I try to import my custom tool palettes onto my co-workers computer, his machine does not see the xpg.
My machine is a 64 bit computer and his is a 32 bit.
Is there a way to convert the xpg to a different extension or will I have to set up his palettes from scratch?

I just migrated from 2006 to 2012... I was able to get my old custom tool palettes into 2012 by opening the Content Browser and idropping them. However I noticed that these palettes are not 'refreshable' like they used to be. In the Palette Properties it says *This palette is not shared from a catalog*... after doing a search of that message in these forums I found this thread: [URL]....
I followed David's instructions:
1. Created a new Palette Group
2. Created a new palette in that Group
3. i-dropped tools from my custom catalog in the Content Browser onto that new palette.
Still there is no 'refresh' option...???

How do I migrate my Custom Tool Palettes and Custom Toolbars from Civil 3D 2012 to Civil 3D 2014?
What files do I need to create or copy to transfer to 2014?
My Custom Tool Palette consists of Block Symbols, Border Sheets, Scales and Seals, Lisp Routines etc.
My Custom Toolbar is just a number of standard cad commands I've put together in my toolbar like Revision Cloud, Layer Isolate, Match Properties, Attach Image, etc.
Do I need to export out my cui file, do I need to create a Profile file, do I need to setup the same directory structure naming and copy my files into those same directory names?
Or is there some easy hidden Magic Button in Civil 3D that you click on and it does the rest?

IProblem 1: Tool Palettes on top of image.
I'm using a 15" thinkpad laptop, with I think 1024 x whatever highest resolution. When I use Gimp, my screen real estate is being eaten up by the tool palettes more so than the image I'm trying to work on. I like the tool palettes - I'd like them to stay open - BUT what I'd really like is for the image to lay over top of the palettes, rather than the palettes lying over top of my image.
Problem 2: Zooming and scrolling in the image.
I'm not too sure what was different about photoshop in this regard, but I'm having a bear of a time getting my images to zoom and scroll in the manner I was used to in photoshop. What can I change in the Gimp settings to make it behave more like photoshop in that regard? I found one setting to increase window size as the image zooms, but that was worse.
I like a lot of the aspects of Gimp, but these two things are preventing me from getting to use it very much presently.

We are using iPart - iAssembly workflow with Inv-2013 and Vault Basic 2013
My question is related to released state of iparts. Currently we are generating/ releasing
all the iparts when new member is added in order to manintain the parent child version relationship
Example : say i have a ipart 41020.ipt and i have members 41020- 001 ~ 008 . I check out the parent
from Vault and add 009 member to it.
Question :
Do I have to generate all and check those in to maintain the version relationship between the child and parent inside
Vault 2013 ?
Or
Only generating 009 will maintain version relationship inside Vault 2013

I opened a 1024x1024 image in GIMP, and manually broke it up into fully black and fully white sections. I'd like to output a file which is just a simple binary array of 8 bit numbers, such that every black pixel in the image has the value 0, and every white pixel has the value 1. This way, I can open it in my C program and then load the array into memory using the fread function.
I haven't been able to work out how to do this. I need to avoid using any files with metadata in them...And unfortunately, even the ppm format has a handful of characters at the beginning. Is there a way to do this?

I created some custom linetypes. When I copied them over to my drawing, the text in the linetypes came in extemely large. I really need to get this figured out as I am setting up a template for a new customer, and they want all these included.

I'm using Gimp on very very large image files, my current image is 22000 x 23000. Gimp has 24GB of memory assigned in the Preferences menu (out of 32) and is fine while editing. However whenever I save the image as an XCF or PSD it corrupts. Occasionally with an XCF it will be recoverable but only one layer will recover. If it's exported as a PSD next time I try to open the image it says there are too many layers and is corrupt.
Is this a bug or is there a way I can preserve my large images with layers?

I'm making a multiple monitor panorama and need to reverse the halves of the large image - 3840x1200 since my primary monitor is on the right.
So I can precisely select the parts I want since Select Rectangle has a precise mode in the tool options.But move has no precise mode.
Don't we need a precise mode in the Move tool too?
Not sure where to pass this along to the Gimpers, but it's the only thing I've found missing.

I have to reduce 4 very large TIF files [each one is about 250MB!] to a more manageable size to stitch together and apply as a watermark. They seem to have been taken at about 1.5km above the ground and are very high resolution at 8000x8000.
I still want to retain reasonable resolution at about 250m above the ground so my question is what is the best way to reduce each down?
Would I resizing them in actual size as well as reducing dpi?

I have to fill in a large area of shingle siding (vertical shake) with color and so far the only way I've discovered to accomplish this is to fill in each individual shake, one-by-one (and there are hundreds and hundreds of them). I'm using a pdf file oepned in Gimp. I tried saving it as a jpeg in the hopes of selecting an entire wall of shakes and coloring them with a single click, but it didn't work.

I have GIMP 2.8.8 installed on Ubuntu 13.10 amd64. The machine has 32Gb of RAM, and in GIMP preferences I have changed "Maximum new image size" to 4Gb and "Maximum undo memory" to 12Gb. However, if I try to open a large image in GIMP. it crashes while trying to open it - for example, this 15427 x 12549 pixel tif image available from the European Southern Observatory web site: [URL]
When I try to open this or similar sized images, the progress bar at the bottom of the file open dialog goes across to 100%, then GIMP stops responding for 10 or 15 seconds, and then the entire GIMP window disappears with no error message from either GIMP or the operating system, System Monitor shows no gimp process running, and the only entry I can find at the relevant time in any of the log files in /var/log is this:
Nov 22 06:15:36 nick-desktop kernel: [ 1458.563084] traps: gimp-2.8[4160] trap int3 ip:7f508c2dd3d9 sp:7fff6768a050 error:0
The same problem happens if I try to create a new large image - select New from the file menu, enter 12000 pixels for the width and height in the dialog, and OK. After 10 or 15 seconds of no response, the GIMP window vanishes. I can open or create and work on smaller images without any problem.
I also have the Windows version of Gimp 2.8.8 installed on my laptop, which is running Windows 8.1, and there I have no problem opening or creating the exact same images.
