GIMP :: How To Process Drawings To Scanned Into High Definition Image
Mar 13, 2011
I love to draw, I would like to use my drawings on some iPhone game. I am wondering how I can process the drawings I scanned into a high definition image? I do my drawings in old fashion paper and pencil way, once The drawings were scanned, the resulting images look very rough, for example, the lines are showing the pencil marks, a straight line has a few bumps in the middle, and circles seem a bit off, is there a way in Gimp to do some fine tuning on the images?

how can I make my images HD (high definition) in Gimp? like there are HD TVs I want to make my images have an HD look to it. I know it is possible to convert SD to HD because I've seen old sports games that were played before HD TVs were invented and the game was converted into HD. although it is not the same as if it was originally recorded in HD
whether the image looks like a SD to HD conversion or looks pure HD, it doesn't really matter to me...
how to I make my images look HD?

Are there any books, articles on High Definition Range for further study out there? Something that would explain the values in the HDR Pro dialog box?

I have just bought a High Def camcorder hoping to get a better picture result onto DVD. I have been using VideoStudio 12 (pro2) for some time now and have only transfered normal camcorder video onto DVD in the past. Do I need to do anything different in the editing/ DVD stage to gain the benifit of High Def ? and would using a Blu Ray disc change anything? Can I get recordable Blu Ray discs, and do I have to have a High Def / Blu Ray recorder on my laptop to get the result I need?

I am purchasing a new computer and whether nVidia or AMD would be better for use with Photoshop CS6. In my previous computers, I've only ever had an integrated video card and they worked okay enough with Photoshop. But now I have the opportunity to purchase a computer with an nVidia/2 Gig Vram or an AMD Radeon/1 gig VRAM video card.
I know so much depends on the cpu speed, ram, whether or not you have multiple hard drives, etcetera. What I want for all the other components of the computer, but I have no working knowledge of video cards.
I use Photoshop for photo editing and I also want to eventually use it for High Definition Photography editing.

I would like to scan an image and clean it afterwards because areas of the same color in the original image (a poker card, so a simple logo with white, black, red, blue and yellow areas) end up to have spots of different color.
Is there a way to improve scan fidelity or edit the image with Gimp in order to smooth these differences and recreate the same areas of uniform color?

Using Gimp 2.8 in Windows 7. I have a scanned image of a topological map. At areas where the contour lines get too close, squares appear in between the image (See attached photo). Is there a good way to remove these extra squares in the contour lines rather than tracing the lines manually?

I am currently running Gimp 2.8 and am a new user. How to make an image's background white. I have a watercolor painting that I have scanned into my computer, however you can see some shadows from the grain and edges of the paper. I have tried some different ways to change the background completely to white, but I feel like maybe I'm missing out on a quicker method. So far, the one I've been working on is taking me longer than it took to even draw and paint the picture in the first place. That method was to use the fuzzy (lasso) tool, make a rough outline of my painting, use the quick mask button in the bottom left hand corner and follow up by using the pencil tool to make a more precise line around the image.
Another tutorial I found showed I should use the Select by color tool, select an area that should be white in my image and press Ctrl+x. However, when I pushed ctrl+x, I saw no change in my background and my image remained outlined in the shifting lines that the select by color tool causes.
Is there a way to achieve a plain white background with out going through the long process of tracing around the detailed image?
It should be noted that I'm not hugely familiar with Gimp as I've only used it a couple of times with tutorials. So, the more basic you can describe something, the better. I am also running Windows 7.

What is wrong with my GIMP? This behavior persists in every 2.6 and 2.8 build I've tried, in fact I'm pretty sure I first discovered it somewhere in 2.4 .
It's GTK bug #644032 - certain adjustments made to the Hue-Saturation tool (with overlap) may have problems handling the red/magenta wraparound properly. Which was supposed to be fixed eons ago (and with exception of this one specific usecase, it already WAS - see GTK #527085).
It originally happened while trying to adjust the color balance on a scanned image containing ambiguously red/magenta hues (yes I know we have an actual tool for Color Balance, but I've never been able to quite wrap my head around what adjustments yield which results). I have attached a sample file demonstrating expected vs. actual results with this usecase. My GIMP is clearly screwing the pooch on these adjustments ... but HOW, because even when I browse the online git repo the relevant source code looks like it should work perfectly (I've even mentally stepped through it and verified correct results, unlike my actual GIMP).
Try performing the same adjustments on your GIMP (note which build and version) - do you get the same results I do?

I need to find out what process is employed to separate an image from its background. An image from one of the image services for example. I need for the actual image to be shed of the often white background in order to better work with an existing background on the graphic. It seems straight forward enough, I just have limited computer graphic chops.

I have been trying to save an image at 1200 dpi. The image turns solid black.
I had this problem once before (months ago). I know it has something to do with the Resource Consumption settings (i.e. Edit -> Preferences -> Environment - > Resource Consumption).
I got it figured out before but I reloaded Gimp on my computer so the settings went back to default. It has something to do with increasing the cache size or the total new image size or something. I can't remember.

So I couldn't think of a better place to put this. I have something that I'm thinking of having professionally printed. What are the steps I should take to make sure I produce a high quality image? File format, Dpi and so forth. Make a list of steps to creating a high quality image file that will look good printed from a print shop.

I'm trying to use 3dsmax 2011 graphite freeform polydraw tools to retopologize a scanned high poly model.
Here are the steps I went through:
1-Imported the high poly mesh (.obj)
2-Converted to editable poly
3-Used ProOptimizer modifier to make the model "lighter" for my pc
4-In the polydraw tools, I selected "Draw On: Surface"
5-"picked" the high poly model
6-Selected offset 0,2
7-Created new object using the polydraw tools "New Object"
8-Froze the high poly model
9-Started retopologizing
The problem is that during the retopology process, my mesh doesn't ''stick'' to the reference high poly model... so I have to stop every now and then to adjust it which takes a lot of time.
I do know that there are a lot more specialized retopo tools like Topogun and 3Dcoat, but acquiring a new tool is not an option at the moment.

my girlfriend's birthday is coming up, and I wanted to do something a little bit different. She's a great artist, and she's drawn a lot of pictures of us together. She's so busy though, that she never has time to finish the drawing completely, so she can't get around to coloring it. I was wondering if you guys could point in the right direction of how to color scanned black and white drawings?

When I used to use photoshop a long time ago (version 5) there was a technique I used to use to draw over the lines of a picture so that I could colour it how I wished and use the shading and burning tools etc to add more life to a picture. However I no longer know how to do this and I'm on version 7.
Basically it involved the lines tool, I would draw around each line of the picture, then add the end use a tool which made the lines smoother and more curved so it didnt look like it was drawn with a ruler, then it would be easy to select the areas in between each line and colour.
When I try to do this in 7 it creates a layer for each seperate line, and I dont remember whether it used to do this or not. Also I cant for the life of me find a way to smoothen them all out and make them as one whole layer like before, instead im left with many awful lines which overlap etc.
how I can do this effect, or a better way of doing so. I read one tutorial that said go over the lines with the pen tool, but that doesnt work at all, and going over with the brush doesnt leave nice defined lines at all and makes it hard to select the blank areas.
I'm using scanned colour drawings of mine.

I have several hundred TIF images at 1200 dpi+ which represent scans of hand drawings on parchment paper using pencil or ink-pen (.2mm or thereabouts) of 4000 year old cuneiform documents. The drawings were made over an extended period of time, the paper varied, and ultimately, the scans reflect this in that some lines are darker than others and there are occasional 'smudgy' areas etc.
What I would like to do prior to publication is to sharpen the images and make them consistent across the repertoire as black on white background.
how various Photoshop (CS5, Mac) commands do what they do, but I've found several that seem like they might get me where I want to go: Levels (Auto?), Threshold, Shadows/Highlights. I'd like to automate to run over a directory of images if possible. At the same time, I might have to change the dpi and output format of the new images.
In this case, the drawing is fairly clear (not much 'grey' background) but the lines are not as black and sharp as they could be.

how to get them clean and crisp? black ink drawings is what im scannin in, ive figured this much out; scan it in at a high resolution (i scaned in at 600dpi), scan it in grayscale, mess with the levels. the overall goal is to scan in a line drawing and color it.
im trying to get the lines to be a uniform solid black. ionno if this is something i should try to get when im actually drawing it or something that is best left to PS. it looks pretty good on paper but when i got it in PS the lines are not as solid as i thought.

I am a newbie to Illustrator. I have scanned in a drawing and opened in illustrator. As it was a jpeg, I then image traced it to turn into vectors - it looks very messy, is there a better way?
I now want to colour parts of it in, but it only allows me to use black, white or gradients in between, how do I add colour? The document colour mode is RGB.

We have created a complex Inventor drawing (Inventor 2013) of a very large plant item which we need to print at about 2AO to put up on a wall for training use. We want to create a high resolution PDF file of the drawing first and then print the PDF having checked the quality and resolution in Acrobat Reader.
We have tried exporting to PDF but we found that the colour shaded fills, behind the lines, are too compressed and the resolution very poor. We tried increasing the paper size but this did not work.We have tried creating a plot file by printing to file using the driver of a large roll feed plotter and then creating a PDF from the resulting file. This was a little more successful but still a long way short of the resolution or line quality we require. When you zoom in the curved lines are very jagged and the colour fill still not good.
We tried printing to a generic Postscript driver but this was even worse as we didn't have enough control over paper size or resolution.

is there a way of exporting my AutoCAD drawings in high quality? Maybe Tiff?
The problems I have with exporting is that if export a drawing as a *.wmf the thick lines come out too thick even when using the 0.3 mm thickness. If i use the 0.25 mm thickness the lines are as thin as with the default thickness.
The contour lines of an image I imported into my AutoCAD drawing are coming all blurry when I export into wmf file even when using the 600 dpi resolution (highest available on the menu).
Inside my AutoCAD drawing my image map has a very high quality but when I export it, with AutoCAD polylines on top of it, the drawing comes out horrible.
I painted a blue polyline to represent a river in a contour map. This is for a civil engineering project. When I export the drawing, the polyline comes out too thick and the image behind comes out blurry. This happens even when using the highest definition possible for a wmf export (600 dpi).
I've read in another thread about a way of exporting into tiff. I followed the directions but the thread is not well explained. It doesn't say whether it is necesary to have or buy certain software. And it doesn't say what to do next to export the tiff drawing.
how to export high quality AutoCAD drawings?

My problem is related with the quality of a image.
My question is how to maintain high quality (original quality) of a image after resizing it?
If i resize it with same ratio like:
2816x2112px to 1600x1200px (4:3)
2816x1584px to 1920x1080px (16:9)
Mainly i use scale image option in Gimp. But now i need to resize many images for my work so i tried David's Batch Processor to resize my images. After using it, i found there is some quality promble with the resized image.
Then i tried, the scale option with, use quality setting from original image and JPEG quality parameter is 95, in gimp but the problem is same. I did it with also with David's batch processor- JPEG quality parameter is 95.
Other thing is that, the original image 2816x2112px (4:3), size- 3.6 MB is displaying in image viewer with 47% and the resized image 1600x1200px (4:3). size- 1.2 MB is displaying in image viewer with 83%, So my questions are: How can i check the quality of a image after resizing it, means the image is exactly same as the original? Or Is David's Batch Processor maintain the original quality of the images after resizing?. I realy need to resize many images for my work.

I'm trying to get myself a little better with digital art, but still not too comfortable with the idea of doing the initial drawing without pen and paper. The only downside is that I can't really get those crisp colors with just pencil colors.
how do I go about setting things up to where I can color in a scanned, non-colored inked page, but without worrying about overlapping my inks and making it look messy in general. I imagine it would have something to do with copying and pasting new layers, but I just can't get a handle on what I'm supposed to do. I also know about messing with opacity to let outlines show through, but there's still the issue of color dulling the black when it overlaps.

I just got a new computer. I had Photo Shop Elements on my old one. I appears that Gimp can do the same things for free. One thing Photo Shop Elements did was provide a way to scan as many photos as would fit on your scanner and then provide a way to separate them. Can Gimp do that? Sometimes I would need to use Elements to open a scanned photo. Would Gimp open a photo scanned on Elements?
I am trying to decide whether to buy Elements for my new Windows 8 or download Gimp.
