GIMP :: Maintain Vector Stroke Width During Rasterization Import?
May 18, 2012
I was wondering if there was any way to maintain stroke width (with antialiasing off) when importing/resampling vector files, like pdf. photoshop does this, i think.
i made a test case that shows the issue in the attached files. the PDF is a 1px-stroked square. when i try to rasterize it to 100dpi (or any dpi other than 72) using Gimp or any tool that relies on ghostscript for rasterization (imagemagick, mupdf, xpdf) i get a square with unevenly stroked edges. photoshop's algo maintains the stroke width in favor of maybe less optimal positioning.
is there any way to make Gimp or any other pdf->png rasterization tool (ghostscript included) prioritize stroke widths over positioning?
What are some of the things I can do to prevent rasterization of vector images when I create them in CorelDraw? Do transparency and gradients cause rasterization?
Trying to use the width tool, I ran into the following problem. I would like to have a smooth transition of the stroke width between two width points while keeping the original stroke width unchanged outside of that line segment.
There are four width points here: two end points and two in between. The original stroke width is 200. The two on the left have one side set to 100 while the two on the right have one side set to 50. I would like to eliminate the distortion of the line width occuring in the first and third line segments. The only solution that I have come up with so far is to place two additional width points very close to the two middle width points: one with a 100-unit side to the left of the second point in the picture and one with a 50-unit side to the right of the third point in the picture. Yet there will be a small distirtion in between.
I've been trying to find out whether gimp can import and edit vector graphics made e.g. with Inkscape as vector graphics and save them as vectorgraphics, for example in pdf. I'm mainly asking this because I need to make some ads for printing and they need to be in good quality and the best way to keep simple graphics in printable quality is to use them in vector graphics. An ad usually requires a background image and for editing those I need gimp. So in the end I need to combine these two elements and when I do it in inkscape I can't practically do anything to the background image, not even crop it properly, if it needs something to be done (It's kind of hard to imagine what the image needs when you don't have the other elements on top of it). To my mind it'd be a lot easier to finish it in gimp where I can do something to the background images, but is it possible?
In Illustrator I want to maintain the stroke settings while creating several paths with the pen tool. However, every time I start a new path, the stroke settings revert to what must be a default. E.g. I set 16pt + Variable width profile + Basic and stroke a path. When I start a new path, the settings revert to 1pt + Uniform + Basic, and I have to reset back to my original. Other art programs I've used maintain the tool settings most recently used until they are manually changed. How can I get the settings to stay through multiple uses of the pen tool?
I'm having trouble with the spacing of my text when I import a .rtf file. The spaces change width based on the width of the columns. The problem does not effect all the paragraphs only select ones. If I change the width of the column the spacing of the text will fix itself. All of the text is the same text style. I have attached a copy for reference.
I have tried numerous times to import from ver3 into ver4 and each time, no matter what I try, I end up with a different look (brightness, contrast etc.) The last time I tried, I reset both 3 and 4 to adobe defaults, then imported 3 to 4 checking none for presets and did not upgrade to image (left the exclamation mark), and the image in 4 looks substantially different that the one in 3. Also, all the sliders are readjusted with this "none" import. They are not at default, which would be zeroed, but all at different settings than the ones in 3. 4's image has less contrast and the color set in the hsl in 3 has been substantially lightened. What am I doing wrong? I read that others can get them into 4 (not upgrading, leaving the exclamation mark) and they are virtually the same rendering.
when I used to paint with Photoshop 7 and a mouse, I had it set up so that my brush strokes would fade gradually as I dragged the brush across the piece, like a real paintbrush running dry with each stroke.
Ever since I upgraded to Photoshop CS and a Wacom Graphire tablet, I can't figure out how to set my brush tool up like I used to have it (I prefer it for speed painting). Currently, my brush strokes vary in width based on the amount of pressure I apply. :B
how to adjust my settings so that the level of pressure on the tablet determines the stroke's transparency as well? Or at least point me to the right thread?
I'm having trouble with stroke option in illustrator. It was working just fine but now its stuck at 1pt and I cant increase or decrease the stroke width no matter what I do.
I have an open path in Photoshop CS4. When I go to stroke the path, Photoshop makes a stroke that closes the path from end to end. I want to stroke just the path with a specified stroke width in a specific color.
I do cartoons and I want to be able to use the pen tool, brush tool and/or even blob brush tool to draw. I'm trying to draw a straight line that has a varied stroke width, so it looks like it's drawn with a felt tip marker or maybe a pencil. The natural random/varied stroke width is what I'm looking for.
I see the "vaiable width profile" drop down box in the tool bar but I only see one option that looks like this (it says "width profile 2" when I mouse over it). Although this varies in width, it's too consistent and doesn't look natural at all. Is there a way to get a varied stroke width for straight lines? I have a pen talet and have tried pen pressure as well but I've not found an easy way to do this.
I'm looking for an existing, or a way to create, a shortcut that will adjust the stoke width in Illustrator as I draw. Something similar to the bracket key in Photoshop for changing brush size on the fly.
I can't believe Illustrator doesn't do this automatically. If you create a stroke profile on one side of the stroke by holding Alt/ Option while dragging with the Width Tool and then mirror the object, the stroke profile doesn't mirror accordingly. You have to go to the Stroke panel and click one of the flipping buttons for each stroke of the mirrored artwork. This makes mirroring complex artwork very time consuming. Mirroring with transform effect doesn't have this problem but this makes the usage and editing of the mirrored object difficult.
I'm just posting this before making a feature request in case I'm missing something. And to check if this problem has been already raised and the feature request made.
I am tried to open the following svg in the illustrator but it was not scaled the stroke-width of the text, even I have changed the units into px. And its kinda merged svg from both illustrator and inkscape generated svgs.

I am trying to create seamless pattern repeats. Most of the time when I do this I get thin lines between the tiles (I place the original pattern and move>copy it to exact measurements). I have read in other forums that these are 'ghost' lines which don't appear when the design is printed out, but I've had fabric samples printed that do contain a line. Also sometimes the motifs on the edge of each tile don't match up - see the slight line down the orange / white cups here:
I move>copy the motifs using the exact measurements of the artboard, I line up my clipping mask with the artboard and they are exactly the same size, and they have no stroke width. I can't work out why it still does not work.
Even before I copy and tile the design I sometimes have a thin white line down one side - see below.
So i have this piece and i need to be able to colour different sections of the stroke around the whole piece with different colours. Also, i need to be able to change the width uniformly on sections between anchor points. I DO NOT want to use live paint as it takes away the sections of stroke i have tapered off already, however, the effect you get when using the live paint selection tool is exactly what i need
Is there a way of doing this at all?? It seems that i should be able to do it but i'm not able to find the right button, option or combination of both.......
Am I the only one who has edited a stroke with the stroke width tool, then outlined the stroke only to find a countless number of points and noticeably unsmooth edges? Is there a setting or certain way to ensure that the stroke width tool won't corrupt the smoothness of my shapes? The stroke width tool is the most handy new feature I can imagine, but this problem makes it almost entirely useless, unless designing something where precision and smoothness are not important.
i have made a custom stroke width profile and want to back it up for future use i found two files called variablewidth or something but the date modified wasn't congruent to when i created the profile.
where can i find the files that contain this preset to back up?
In Illustrator CS6 and CC, when the stroke width tool is used on a curve, the curve is actually made up of a series of straight lines instead of smooth vector curves:
whereas in CS5 it looks perfect.These images may be too small to see the details, but the difference is there. Is there a workaround for this? Or is it recognized as a bug?
I have 2x user presets (one for each of 2x camera's), which I use to apply to images on Import.
When moving a catalog from my laptop (rMPB) to the desktop (iMac) (created of just one image folder), using the export / import catalog routine, these presets just list as "unavailable preset" in the Develop Status metadata sorting options in the library module.
I have exported these presets from the laptop and imported them to the desktop and then re- exported/imported the catalog but the results are the same. Is there a way for these presets to be recognized and sorted by correctly when importing a catalog?
I've created a rectangle and a shape with the bezier tool. I've tried to make the stroke thicker but can't. I've tried selecting the path/mask several ways and chosen different tools in the toolbox but no matter what I do, the Stroke option in the menu is greyed out.
is there a way to do this?
either edit the stroke afterwards - or even specify the width before drawing a path?
I use and really like Corel Draw X3 (almost 3 years) and will keep that version on one P4 computer that runs win xp pro 32 bit.
X3 has been a great version that never crashes but it is getting slow as I increase the number of objects and symbols in my files. I have a new comp with win 7 pro 64 bit running CDraw X6 and the latest epilog 64 bit driver for my mini 24. I have been using the new X6 for 3 days .
In X3 a hairline or .001 is a vector cut. A line width of .005 and above are raster lines and they work well in my Epilog mini 24. I am using a 1.5" diam lens. In X6 a .005 line will not raster but only vectors. If I change it to .006 it becomes a raster line and will engrave OK.
The big Question:
Is there a way to make .005 raster as it did in X3? I have hundreds of files that are all .005 line width. I don't mind changing them but would rather not.
Could this change be because of the latest Epilog 64 bit driver that I am using with win 7 pro? Almost all my files have oddles of very fine detail (.005) and they would look a bit muddy changing the line width to .006.
