Yes, simply use "Nearest neighbour" as the resample algorithm in the "image size" dialog (image -> image size) Edit: @CAI gives a nice tip - "It's also worth mentioning, if you don't want any distortion at all, multiply the scale by whole multipliers (so 2x, 3x, 4x or 200%, 300%, 400% etc.)"

Just think of pixel like an atom. The atom is a smallest particle of matter. Where as a pixel is a smallest particle of digital image. An atom has neutron, proton & electron whereas a pixel has red, green & blue values :) The number of pixels per inches or centimeter (cm) etc. is called the "resolution". A higher resolution means more pixels per ...

File > Save for Web and then enter the pixel dimensions by clicking the Image Size tab on the right of the Save for Web window. Or am I not understanding you correctly?

A pixel is a pixel is a pixel. Resolution (as in PPI/DPI) is meaningless* in a digital context, the only time it is meaningful is when you are printing (or otherwise transferring to a physical medium) your image. A 100 × 100 pixel image saved at 72PPI will show on your screen exactly the same as the same as a 100 × 100 pixel image saved ...

You'll want to use the Pencil tool instead of Brush tool. It allows you to do pixel level edits without any anti-aliasing (the fuzzy area). It's located below the Brush tool or can be accessed by repeatedly pressingShift+B until it cycles around.

On a normal monitor imaging element is in a square matrix. We then call the aspect ratio of that pixel 1. Aspect ratio is just the width/height. A aspect ratio of 1 is a square and a aspect of 16/9 is elongated. In the case of monitors we have 2 separate aspect ratios the ratio of the monitor and the shape of each pixel, called pixel aspect ratio. These two ...

In the top right corner fly out menu of the transform panel, you can select or deselect "Align New Objects To Pixel Grid" globally for all future objects/paths (see below image) For each already created path/object use the checkbox in the transform panel itself The paths within the symbol might be set to "Align To Pixel Grid". Disabling it for the specific ...

After a few minutes more of poking around in Gimp I finally noticed that the selection tool had an anti-aliasing option, that was turned on. If this is not selected you get hard edged fills.

Sadly, menu Extensions -> Render -> Grids > Grid... does only take pixels as the measurement. So I am pretty sure conversion is the way to do it. I find the easiest, most accurate way to do conversion calculations for Inkscape is to do it in Inkscape. Use the rectangle tool to draw a rectangle on the canvas, then in the tools control bar for the rectangle ...

If a client of mine asked for a 1920x1080px image, the first thing I need to know the intended use. Is it for the web, print, or both? In the print world, a pixel (or picture element - [pict-el]) has no meaning or definition. Pixels can not be measured in any way. They have no predefined size or unit in order to calculate their size. Therefore are not a "...

Using File → Save for Web and entering the dimensions will do what you're after. Also, Illustrator uses vector scaling, so the results are better than if you tried the same thing in Photoshop — entering dimensions that don't match the document in Photoshop means the image will be bitmap scaled. Please note that you have to click Apply after changing the ...

Not exactly, but... ... there is a way to achieve the effect you describe. Apparently you can change the scaling mode for smart objects, but it's a global setting that takes effect for newly created Smart Objects: Preferences > General > Image Interpolation. So the procedure is like this: Open your background image Set Preferences > General > Image ...

Pixel fonts aren't terribly different from tiny print fonts when you get right down to it*. The one big exception is that you know what the medium will do with pixel fonts -- a very big advantage. There really isn't an ideal pixel grid, per se. Obviously a larger grid gives you more room to work. The smallest types I've seen work successfully are 7px ...

As people have commented, coding would yield the best solution. You can get a good approximation using Image > Adjustments > Gradient Map... Fill a canvas with 400% noise: Filter using Pixelate > Mosaic... Increase the saturation: And re-tone the image with Gradient Map: Result:

No this is not possible. To be entirely sure I went through every option that the layer has. A workaround might be setting up guides with the size you want the pixels to be and then using the Pencil tool to fill them.


11

No. I'd approach it one of these two ways: Use a multiplier for your pixel brush size, and just use nearest neighbour interpolation to resize your image to the correct size without deforming it. (let's say you had to blow up your pixel art 10x, just use a 10px square brush). You can always have a second view zoommed out to simulate the final size. ...

As of GIMP 2.8, the way to paint with a 1 pixel brush using the pencil tool is setting the brush size to "1" in the Pencil tool options, when painting, regardless of Brush's shape or native size. In previous GIMP versions, the "pixel" Brush which was an image one pixel in size was available in the UI. It is currently hidden, and available only for scripts ...

I'm not sure if this is the case, but sometimes the icons are made with a double stroke to mimic a fake stroke width. At the icons below there are three different strokes: 1px 1px black + 2px grey 2px This is the second icon structure:

Joe Gillespie did some great micro screen font work under the MiniFonts moniker. These are still available via MyFonts. Silkscreen is a related design by Jason Kottke.

There is a very fast and efficient method to remove single pixel noise from a transparent background shown in this example picture: Use the fuzzy select tool to select the fully transparent background with following settings: Select Antialiasing Select Feather Edges Adjust feather radius to include the size of all noize pixels. Tick Select transparent ...

I prefer to use Inkscape's built-in document grid option. Press Shift+Ctrl+D or navigate to File→Document Properties→Grids Select Rectangular Grid and hit the New button. You can then edit the properties (and units) of the created grid in the same dialog.

It depends on what results you want. If you want it to look "blocky" (i.e. each pixel in the original becomes a square in the result) then MrMerrick's answer is correct. If you don't want it to look either blurry or blocky then you need a dedicated pixel art scaling algorithm. I'm not sure if such algorithsm are available for photoshop, I did find a plugin ...

Another possibility, here; try drawing your images using vector shapes. There is a little time investment, but the potential afterwards could pay dividends. Start by setting your grid size (say grid line every 10 pixels, with only 1 subdivision). Turn on grid snap. Using the pen tool draw your shape. For any parts of the shape that are separated (i.e. on a ...

Short answer: One pixel can contain one color (and one value for opacity, but that's not relevant here). The different letters/number you see in your color code are the values that constitute it. HTML colors are defined using a hexadecimal notation (HEX), those are the letters/numbers you see, and they are the combination of Red, Green, and Blue color ...

There is a computer science paper (really, fun memo) titled, "A pixel is not a little square" by Alvoy Ray Smith. A pixel is a point sample. It exists only at a point. For a color picture, a pixel might actually contain three samples, one for each primary color contributing to the picture at the sampling point. We can still think of this as a point ...

As you put it, vectorizing every pixel makes no sense. Imagine you vectorize every pixel and then resize it. You simply have bigger squares. The exact same thing happens if you change the ppi on an output, you have bigger pixels. You do not need to resample it. You want to get rid of the blurriness. That is a totally different issue. That happens when the ...

The View → Pixel Aspect Ratio setting in Photoshop simulates non-square (elongated, rectangular) pixels on a square-pixel screen, primarily for preview purposes. Photoshop does this simply by scaling the work area along one of the axes to get the desired, simulated pixel shape. The scaling takes place for display purposes only; when you change the pixel ...

It's only for print/manufacturing conversions. The operating system does not, most of the time, know what kind of screen is attached to the computer. So it does not even try to guess. Because it can not know it can not scale to physical size. But even in cases where it does, it does not even try because that would be even worse. DPI/PPI/LPI and physical ...

you're probably best to do this when setting up a new document in the document set up dialogue box. i think you can also turn it off in the preferences which would be a good idea because in my experience it does nothing but cause trouble!

Ok turns out that the 'Hardness' setting of 1 was the problem... I thought that hardness would affect antialiasing of the edge of the brush, and that a one pixel brush would need to have a hard edge or it would be invisible. It seems that the edge is not within the brush width, but around it, so that a one pixel brush with an edge is three pixels wide ...
