What Is the Difference Between 32 Bit Float and 32 Bit Fixed Pixel Types?

Lets keep things simple by thinking about a monochrome image.To represent out image we cut it up into a grid of pixels and record a number representing the light intensity at each pixel. For simplicity lets assume that the value linearly represents the ammount of light (reality is a little more complicated than that, but it's close enough for now). However we still have to actually represent that number as a bit pattern. There are an infinite number of possible light intensity values but only a finite number of possible bit patterns of a given size. Clearly we must make a compromise.There are basically two strategies for representing numbers on computers, fixed-point and floating point (integers can be considered a special case of fixed point). There is also the question of signed verses unsigned.In a fixed point number we fix the scale factor in advance. So for example to represent numbers in the range 0 to 1 inclusive we might use a 32-bit unsigned number with a scale factor of 1/(232-1). In a floating point number we allow a range of scale factors to be chosen. We do this by splitting our bits up. Some bits are used to store a binary number and other bits are used to store what power of 2 to scale that binary number by (there is a bit of extra trickery in practice, read IEEE 754 if you really want the gory details). With floating point numbers we can store a very wide range of numbers but the precision varies depending on the value of the number. When dealing with a camera, screen or printer our hardware determines the darkest possible and lightest possible values and typically breaks up the possible values in between in a roughly equal manner. Negative values do not really make any physical sense since there is no such thing as negative light. On the other hand when we get into the world of 3D modelling it can be useful to represent a much wider range of brightness values. There can be a vast difference in brightness between the brightest and darkest parts of the world and while negative light does not physically exist that does not mean you can not have it in a 3D model. So formats using signed floating point numbers can start to make sense.Of course there is a price to pay. The 32-bit signed floating point number can represent much larger and much smaller values than the 32-bit unsigned fixed point number but in some cases it will have a lower precision.

1. What is an 8 Mega Pixel Camera?

Ruch explained what megapixels are. 90% of shutterbugs would be satisfied with 5 to 8 megapixels for point and shoot cameras. I would add that features on a point and shoot are more important than megapixels

2. Achieving 1 pixel outline around sprites which changes colour depending on the background?

I think there is a simple/dump way of achieving this (which I have not tried yet on code).Assets:What you do is render the game in 3 layers:You also need a "hidden" layer, one that will not be rendered directly on the scene. This layer will contain the "outline" sprites (which should be aligned with the regular sprites). This layer will be in turn used as the mask of the "border-color" layer.I got the following working on Pixelmator (something like Photoshop) real quick with sprites I found on the Internet:The border-color image is simply the background with inverted colours

3. How to save power point slide as a 8000 x 4500 pixel image?

When you save a slide as JPG/PNG/BMP/etc, it exports at 96dpi, so you get an image size that's the slide width (in inches) times 96. Typical widescreen PPT slide is 13.333 wide, so this fits.You can use a bit of VBA to arf out a higher resolution image; until recently, even VBA was limited to exporting images 3070 pixels wide, max. But as of Office 2016, you can create considerably higher resolution images. Example VBA:.

4. Why is the media query pixel half the spec pixel value?

In my opinion, we need to explore some aspects of the history of the monitors and displays.The early digital images were made of really big picture elements, pixels, because of the poor processing power.As processing power evolved, you can process more pixels on a screen, therefore, less noticeable. At some point, the pixel size was good enough, so more pixels could be used now for bigger screens, maintaining somehow an average pixel density, (how many pixels were on a physical unit, an inch).One example is that you could find for example computers using, let's say, 800x600px on a 15 inches monitor or 1024x768 on 17 inches ones an improved system.This would be the times when Windows defined its resolution to be 96 PPI as being superior to the 72 PPI defined by apple on the earlier Apple systems. ..All this time the pixels were just projected on cathodic ray monitors; in an analogic way, they were not an intrinsic part of the monitor, of the display.Then the digital displays came into the game. Plasma and LCD monitors had a specific native matrix of display elements. Now the minimum size of a displayed element of an image was defined by the actual size of this display elements. Where the projection of the pixels once defined the resolution now they were defined by this display elements.The term pixel was already established. No new term was invented for this digitally controlled display elements. .. And the confusion started. The CSS specification started when the displays were still CRT based, and on a time when the pixel density was more or less stable.So using px as a unit was a reasonably good idea. In fact was a better idea than the previous one, using the "Medium unit". This unit was defined by the browser alone, to whatever the developers considered "medium". To prevent this discrepancies, people used more and more the unit px which was stable enough.As miniaturization of the components made portability a reality, this extra power was not used only for bigger displays, now were used for the original usage. .. more definition using smaller pixels. As a marketing strategy, Apple uses the retina display concept to emphasize the resolution using small display elements.But as you reduce the pixel size you can not use it to define text size, because your text would be tiny and unreadable.There are different "pixels" involved now. The display elements, the actual digital picture element in the case of images, and the px CSS units.To solve this we add more ingredients to the salad... 2x and 3x assets, real pixels and declared pixels. ..Declared unitA phone (or screen) needs to declare to the browser a pixel size, to be used as a reference for the CSS units.This is the smaller unit. 375px in this case. This unit is the one used to define for example the text size and the images size to be displayed on the screen.Hardware resolutionAnd this is the real capacity of the screen due to the physical dimensions of its display elements. Normally it is a FullHD screen bigger or smaller in physical size depending on the model.This resolution is greater than the declared one, and this extra power is used to render more definition to text, and behind the scenes to pull a higher resolution asset... a 2x image or a 3x one
