What file format to elect: bitmap or vector?
By: morleyvinkOne of the first 10 interrogatives people can ask while inventing their first icon styling or barely investigating this question is the next one: "Why so many icons were developed in bitmap file type while vector format provides all parameters of a thing?"
So as we think that among our clients we can discover a lot of newbies in icon styling by that reason let us first learn basic information about bitmap and vector file types.
We can guarantee that this file was invented in bitmap format if it ends with ".jpg", ".png", ".tiff" and others. Bitmap format means that this file is created in pixels and as we know pixel is a tiny square of light and our computer monitor is nothing more than a variety of pixels combined together. Pixel signifies "picture element". It is very simple to see these small squares of light if you have at home such kind of monitor as LCD flat panel screen. In all 24x24 Awesome Icons that were invented in bitmap we have a chance to discover 576 pixels. In numeric code of an image every pixel will be just a number of bits. Naturally if you need to create a large picture you have to own more pixels for inventing it.
You will face with a vector graphic file if you would meet a file which ends with ".eps", ".svg" and others. This graphic file type consists of geometric and mathematical info. So to make 24x24 Best Icons in this file type we just have to write color and original size, but keep in mind icon in vectors could fit for any parametres because it will be invented in geometric proportions such as location of four nooks in pixel squares. This file type needs only 6 bits of data compared with bitmap which requires 576 bits.
So chief privileges of vector format are scale for any graphic file parametres and smaller amount of bits compared with bitmap one. But why web graphic creators continue to create details for every parametres?
The answer is very technical and easy - the deal is in relativity. So all becomes quite natural in practice, do similar icons in miscellanious pixel proportions: 24x24 Icons, 32X32 Icons, 48x48 Icons and perhaps 16x16 Icons. Also produce similar icon it in one vector parametres for example let it will be 24x24 Icon and then scale it mathematically to the similar parametres as bitmap file type.
Created? Now see attentively all icons, don't you remark the dissemblance? Surely you will because it is very hard not to notice it, the thing is that every icon looks very neatly in bitmap file type, but when we look at icons in vector file type we have an opportunity to remark that only icon with original format, 24x24, looks excellent and other icons look diffused.
"But how you can explain it, if you said they can scale to any parametres?"- you will potentially interrogate. Our report will be also technical and easy, the deal is that many laptops present days still labour with pixel based screens, that is why if you bring vector picture firstly done in such proportions as 24x24 and need to scale it to 16x16 certainly you will meet with a mismatch of relative proportions and the picture will look diffused.
