Illustrator :: How To Easily Hatch Complex Grayscale Image
Mar 8, 2014
I've been trying to hatch a complex image with a single pattern, but with different stroke weights.
Here I added an image of a simple greyscale image with below the hatching that I'm trying to make. In short: I want to use only 45 deg. hatches in this direction. However, based on the grey value, I'd like the hatches to have different weights.
However, since this image is quite simple, only four different weights were needed. However, I'd like to know if there is an easy way to do this for complex images. For this image I just used pattern fills with different stroke weights, but I'd like a smoother and easier solution, preferably one where it would be possible to have many different weights without having to split up the image in thirty different parts and making thirty different pattern fills.
I'm not sure if this is possible, but I might be overlooking something. If it would be possible with a plugin, I'd like to know too. Even if there might be a workaround via Photoshop, and the end-result would not be a perfect vector, It'd be fine.
I've read that it is possible to "hand draft" small complex areas that a corridor cannot handle easily.
I have an intersection in an old neighborhood that is constrained by retaining walls, buildings, and so on. In this I have to fit in current ADA ramps. Due to constrained space I will have to get creative in my elevations and layouts.I'd like to somehow integrate it with the corridor.
I used to be able to hatch most anything without problem. Now with Civil 3d 2011 anything more complex that a box or a circle AutoCAD will not find the boundary even when the quick preview seems to find a boundary.
I've tried overlapping the lines and then trimming. I've tried extending to the other lines. I've tried setting the tolerance to 1/2". I've checked that the lines are snapped to endpoints and meet cleanly.
In testing I've found that sometimes it will find the boundary, and other times it will not even when nothing has changed? Noticing that they have to try multiple times and methods to get C3D 2011 to hatch correctly?
The attached file shows the different results (boundaries extracted from successful hatches) that I'm seeing, and sometimes can't find a boundary at all, sometimes it does. Seems to get different results when I regent and at different zooms (not sure if that's the correct terminology?).
I have a grayscale tif of a golf ball that I want to turn into one PMS color vector art, using only screens of that PMS color. I can convert it to vector easy enough but having no luck getting it to my chosen color.
I tried Illustrator support but some of the dialogue boxes they reference don't match what's there.
I'm working with a couple Illustrator stock patterns. I'd like to simply invert them so they're white instead of black. Any way to do this without actually editing the pattern itself? The one I'm working on is too complex to edit effectively...
I have been tying to figure out how I could easily embed multiple linked images easily. I have some 1000 .svg images which have about 1-7 .tif images linked in to them. I now need to get those links embedded and becouse of the amount of images I'm hoping to make an action out of it.
I have set up a 20x20 pixel grid and I want to easily try out a few mockup layouts. No matter what I try, Illustrator simply does not snap to grid. I have to zoom in really close to align each shape.
Surprisingly it does not snap to guides either, leaving me completely hopeless. I have snap to pixel on and all objects are set to align to pixel grid.
i regularly have to print out colours for sublimating fabric, and use illustrator to create a panel of blends to print out.
I put four colours in the corners, make an 18 step blend or the top two, then the bottom two, expand them then ungroup them, and then change the blend options to 8 steps and blend them vertically one by one.
all in all it's several minutes work, but i thought i could change the values of the four corners, and then use actions to blend the grid.
initially it stopped and told me ungroup was unavailable, so i created smaller steps, but still can't get it to work.
is this possible, or do i carry on manually crating grids? or is there another way?
Say I had a group of windows in one layer. A wall in a layer beneath and a giant flock of birds in the layer below that. How would I be able to make the birds visible in the windows while keeping the flock easily editable? CLipping masks seem to only work well with single objects.
I'm working on a part of an image that, I suppose, is "complex".
I'll start by saying I have no snap to options selected. I'm zoomed to a section of an image and moving the node arrows to create the pattern. Why do the arrows push each other out of the way? How do I manage node manipulation without the pushy arrows? Is it possible to have too many nodes? I only have this happen when working on something with a lot of nodes.
if it was indeed possible to remove text from an image with rather detailed background. I'm no stranger to Photoshop and the Adobe Family however I've tried several methods and all of them seem to work but finished result looks obviously doctored...
Here is the image, my client wants the price from the image to vanish, while retaining the background!I have tried myself to accomplish such a result but my attempts at this
I was sent a complex illustrator file recently that contained a lot of distress patterns and points that is basically impossible to work with. It takes 10-15 seconds just to select or deselect any of the objects. I'll I need to do is move the art around a little and resize stuff, but it's taking ages with the lag. I'm using CC on Windows 7 64bit. What options are there to work around this? Is there a way to tell Illustartor to stop rendering, so I can just move stuff around without it lagging so bad? I thought the new engine was supposed to be faster and better at rendering.
i keep getting the error message "Not enough Memory was available or an object was too complex" . . it's a small file and i have a new computer and this was happening on my old computer ?
I am trying to save an illustrator EPS file to a High Quality PDF file
I use some graphics software that accept the image in the form of grayscale as follow :the software then convert this grayscale to a 3d relief.is there a method to convert any image to such format with there details ?
I happened to download a rather dark black and white entry into Photoshop and noticed it was several shades lighter in Photoshop than in my browser. It loaded in Photoshop in Grayscale mode. So I tried this:
1. Open Photoshop.
2. Set the background colour to 53 Red, 53 Green, 53 Blue.
3. Select File - New, set the Width to 800 pixels; the Height to 600 pixels; leave Resolution at 72; set Color Mode to Grayscale - 8 bit; set Background Contents to Background Color; and click OK.
4. Save as a jpeg (maximum quality).
5. Open the jpeg in your browser.
When I do this the browser image (I tried both IE and Firefox) is a shade or two darker than the Photoshop image. I used the Colorzilla extension in Firefox to measure the actual color displayed and it comes out at 37 Red, 37 Green, 37 Blue.
I have a creative director who loves to bring grayscale tiffs into quark xpress, set the color of the tiff to one color and then select the image background "box" and set it to another color.
The result is visually ok, but it all has to be recreated in photoshop to print well. I have been using photoshop for years, and a duotone is not the answer, at least with the curves i have played around with.
What is the best way to recreate this effect in photoshop?
I downloaded an image of the internet to edit [URL]......
Because I want to edit the base and put clothes on it and such. I opened the image in gimp and added the lines for the clothes on multiple layers. I went in to color it and the color showed up grey, any color i used turned out to be grey. Then I looked up at where they put the name of the image and it says: (greyscale, 6 layers) I assume that why i cant color it. is their any way to change this so i can add and edit color?
Lately I have been experiencing this weird problem. Every time I try to convert my image to grayscale mode, instead of just being black and white the image turns purple. Is there anyway to fix this problem? ....
I will submit the Black and white ad created in Photoshop to the magazine. The requiment is that for grayscale images, the shadow density should be no darker than 90% and highlights should be no lighter than 3%. I don't know how to check the percentage on the document I made. I checked HELP in Photoshop and website. But I couldn't really get answer from them. I have little knowledge of printing. Please give me advice or helpful website.
I have a grayscale image that I want to apply color to. I know how to do that by just colorizing it, but instead, I want to apply a color for the whole document. I know how to do this if I want it to be, say, blue (where black is 100 percent of my blue and 50% gray is 50% of my blue, etc.). But, what if I want a unique gradient across the image (where 100% is blue, 50% is 50% red, 10% is yellow, etc.)? How would I do that?
eliminate the fragments from a grayscale image. I used a JPG. You never get just black and white because of the edge transition. So, the image was made bitmap transparent, and contone recolored light and dark to red. You don't get edge blending this way. Xara alphe channel traces to black, therefore the image needs to be something other than black. I made a bitmap copy/alpha for tracing. You need a copy othewise the trace image would be gray scale. Xara seeems to take what is in memory. I think you can see the alpha channel traces black. Xara appears to trace from the bottom up, and the bottom of the image will trace to the background object.
I need to transform a selection of ranges of grayscale image in colors. For example: using GSM of a gray scale image as a parameter I want to recode pixels from 0 to 20 in red, 21 to 40 in orange, 41 to 60 in yellow and so forth... until pixel valued 256 in GSM.
I have very complex file, with hundreds of paths, shapes, text, outlined text, etc... It's a brochure with graphs, scematich drawings and text.
Last moment, the client like the reverse the colors from (current) Black on white, to all White on dark gray background.
Problem is, I can't seem to find easy way to just change the colors, without selecting one by one, every single object. When I selest all and choose white, it start filling paths with solid fill... Editing it wastes allot of my time and I have many pages to do.
Is there any way to simple change color of everything at once, just from black to white ? Or do I have to go object by object manually ?
With Eyedropper Tool click unselected Source Object, (which has 1 fill and 2 stroke attributes) the Eyedropper Tool stem detects Source Object's attributes...then, pressing Option key, click on Destination Object (which contains a default fill and stroke).The Destination Object only receives the base fill and stroke of the Source Object... it should receive all the attributes of the Source Object.
NOTE: 'New Art has Basic Appearance' is unchecked in the Appearance Panel.
