I've tried adjusting levels, curves, color balance and the heal plug-in, but I can't remove the red blocky pixels in a series of pictures that look like the one below:
How I could fix up these pictures? Do I need to use a red-eye or noise removal method? I'm using GIMP 2.6.11 .
Drawing A has a grid system Xref-ed into it. It also has a block reference in it, repeated in various places throughout the drawing.
I Xref-ed the grid into the block to check something, and now I can't get it out. This means that the grid now repeats all over Drawing A as well and is generally being a nuisance.
If I try to unload the Xref within the block, it unloads it in Drawing A too. If I try to detach it from the block, it returns this message: Xref [Xref name] has multiple references. Not detached. If I try to detach the Xred from Drawing A, it returns the same message.
How do I unload the same Xref that occurs in a block in a drawing, and in the drawing itself, independently of each other?
2 days on GIMP. I need to adjust the clone tool so it's 1080 pixels vertical and about 20 pixels wide. I googled and searched, but I can't seem to find the right phrasing.

It is important that the pixels are removed in a random fashion - that is, if I modify a series of images in this way, I don't want the black areas to always appear in the same portions of the images.

And is it possible to increase/decrease of all semi transparent pixels at one time?
For example: When i choose the increasing tranparency-alpha value at 20
if a pixels transparency is 120, it will be 140
if 75, it will be 95
if 255, keep it same
if 0, keep it same

View 1 Replies View RelatedI get an AutoCAD drawing from my conveyor manufacturer who have buried a block (tagname) in all of their conveyor blocks.
The only way to remove them is to manually use BEDIT and erase the tagname block.
Is there a way through Autolisp to search all blocks in a drawings and if the tagname block is part of the definition of the conveyor block, erase the tagname block or redefine the conveyor block without the tagname block.
Remove the attributes from this block.
I just want to be left with the block with all its rotate and stretch features but with no option to add in text when I double click it.

View 9 Replies View RelatedI've just been sent some layouts by our planning team and they have attributes stating the size and name of all the furniture.
How can I quickly hide or delete the attributes as for my purposes the text is irrelevant and gets in the way?
I have tried the BATTMAN command but it doesn't seem to let me delete all of the attributes I have to leave one on each block. Currently all of the attributes are on the same layer as the lines (layer 0.)
I have a diagram scanned in one pixel mode (b&w). I want to change the line color from black to blue.
I tried this:
In the toolbox I altered the foreground color to blue. In the 'Select' menu I used the 'By color' option. I made sure the settings in the toolbox for 'Select by color' were set at default, then I clicked on a black pixel in the image. The black lines in the image became outlined with a dotted line. I then used the 'Fill with FG color' option from the edit menu. The sample color to the left of the menu item was blue. The image briefly 'repainted'. I removed the selection using 'Select' 'None' but the image lines remain black.
I rotated some pixels, but afterwards when I do something else, the pixels become unrotated. I tried saving the image, but that reverts the rotation, too. Why won't the pixels stay put?
View 1 Replies View RelatedI'm working with some "dirty" blocks that contain several attributes. I've cleaned the blocks up by wblocking, cleaning, & purging the newly created block. I also removed any attributes within the file, including those within blocks within the file. I then renamed the file and inserted it into the drawing, and did a replace block with another through express tools. The problem that I have is the blocks are replaced with the clean version, yet the attributes remain. Is there a solution to this. I do not want any attributes to remain and the only way I know how to fix it is to replace them one at a time.
Also, I'm using AutoCAD 2004.
How do you see the size of a selection (in pixels?). In Photoshop this would be in the info dialogue window. I'm not finding the equivalent in GIMP (2.6).
View 6 Replies View RelatedWhenever I use the Crop to Selection tool (with a rectangular selection), it doesn't actually crop TO the selection, it usually leaves an extra pixel on two edges.

View 5 Replies View RelatedI have a square selection that I'd like to map into a circle of equal size. I see apply lens and map object...sphere, but neither of these seem to do a proper job.
The algorithm I'm after would basically take the pixels of the square and map them onto their new locations within the circle so that each pixel moves inward toward the center until it reaches its appropriate location along the the line from the origin to its radius.
I'm about to the point to just code it in C++.
Is there a way to get a brush exactly 2 pixels square? If i set the Radius to 0.7, i get a 3 pixel brush, if set to 0.6, i get a 1 pixel square brush. I mainly use GIMP to touch up scanned in forms and tables and most of the lines are 2 pixels which means twice as much work to correct a skewed line.

how do i get rid of white pixels in the background
I'm working on a very small scale, and need to find a way to make an image which consists of 4 colors, randomly spread around the 16x16 pixels.
I have not been abel to get the desired affect with any of the noise filters, so I was thinking I could make 4 layers, one with each color, delete the parts I don't want and just merge them down.
Now, with such a small scale, I could do the work by hand, but I have to repeat the process at least a dozen times, and I want it to look truly random.
Here are some brushes at radii 0.1, 0.2, 0.3, 1, 10, and 50.I thought brush radius was measured in pixels, or would at least scale in a linear fashion, but this shows otherwise. Why the maximum brush radius is set to a (small) fraction of the full slider?
I just found the Size slider that's separate from brushes... Woops. Radius slider still confuses me, but it's not a problem anymore. I don't see a delete button around, either. :/
I have an image with an transparent background. I want to change all pixels that are not the background to one color. How do I do this? I can't select the pixels, they as arbitrariliy distibuted. I've played with threshold, but that's not working either. I tried Image-->Mode -> Indexed and then Use black and white palette, but that doesn't work either. I thought i would convert all non-transparent values to black, but instead its picking some threshold and making some black and others transparent. Example file attached.
View 4 Replies View RelatedI've just started playing around with GIMP. I've made two images containing a text to start with. For DPL2.tiff, the resolution (both X and Y) is 72 pixels/in, for DPL4.tiff it is 1 pixel/in.
My question is, shouldn't there be a noticeable difference in quality of the images?
I had a .JPEG of a leaf photographed against a white background. When I went to turn that white background into a transparent alpha channel, it seemed to work okay....except for the fact that when I then went to select the new alpha channel via the Fuzzy Select Tool, it wasn't selecting all these newly transparent pixels.
View 6 Replies View RelatedHow can I control the color of transparent pixels?
I save my image in RGBA (Windows bitmap). The RGB value of the completely transparent areas always turn completely black, and I want to control the color myself.
It may seem pointless, as the color is transparent, but I am using the image elsewhere (for creating mipmaps) where there is interpolation between pixels. Interpolating between 0 and 1 in opacity gives 50%, but the RGB part of the interpolation will mix with black, giving a dark halo.
1.I am working on a project where I need to set all pixels below a level as alpha channel, is there a quick way to achieve this? The level can be both set a prior or adjusted dynamically, the second way is preferred. Right now my workflow includes:1. duplicate layer.
2. use color level in duplicate layer, in menu COLOR -> LEVEL.
3. add alpha mask to original layer
4. copy duplicate layer into the alpha mask of the original.
5. delete duplicate layer.
6. If result is not ok then return to 1.As you can see this workflow is a headache, specially point 6 which is often achieved.
Whenever I paste an image from the internet into Gimp, the image is shifted 3 pixels to the right, and those three pixel columns wrap around to the left side. At the bottom of those three now leftmost columns are a red, green, and blue pixel.
What the bottom left corner looks like:
This only started recently and I can't think of anything I changed recently to trigger it.
I have a big wallpaper and i would like to set the firm logo in the left bodom corner with something like 40 pixel from the left border en 100 pixels from the bodom corner.
