![]() ![]() Now see the following the picture can you see any difference between two pictures These samples pictures are in the demo and with the source in the release folder. When you are going to try my demo ,you will find three pictures ,use them with the program using the password 'aaaaa' (take care it is CASE SENSTIVE) and read my msg to you then vote for my work. Well since it is just one bit change in each byte so our eye never be able to see the such difference.Saving the result back to the bmp file.Then adding to it 1 or not depending on the srcBin array.Reading the bmp file and ANDing each byte with the mask 254 '1111 1110'.Reading the text file and converting each char.Using the code Hiding the text in the bmp file technique: If we have 'H' '0100 1001' and we want to change the last bit to 0 simply we ANDed 'H' with the mask 254 ('1111 1110), the result will be '0100 1000' and if the last bit is '0' and we want to change it to 1 so we first ANDed with the same mask then add 1. How To change a certain bit in a byte using MASK: In the c/c++ there is a bitwise operator ,one of these operators is the AND " & ", to see the AND operation look at the following table : In general the bmp file consists in of two parts a header and the data part. Selecting a region changes the language and/or content on are many methods to convert from decimal to binary but I found this is from the fastest methods. As the default native format of Adobe Illustrator, AI files will only continue to grow in popularity. While people still use EPS files, designers and illustrators can just as easily create the same image types in AI files. Illustrator is also useful for typography design - creating fonts - and AI files are known for their ability to display fonts with precision.ĪI files are becoming increasingly more commonplace than EPS. Graphic designers often use them for logos, icons, posters, and prints. Today, JPEGs, GIFs, and PNGs have replaced EPS for web use cases. However, EPS remains useful for printing - especially with images that contain complex graphics and high-resolution elements.ĪI files are popular for small-scale graphics, especially for those with clean, sharp lines. The original use of EPS files was to embed images in websites and print advanced graphics. With layers, transparency helps graphic designers build artwork that they can use anywhere a design needs to seamlessly appear on top of various backgrounds, like a logo on a webpage. A single page contains all its image data plus many different artboards, making the AI format easy to manipulate.Īnother advantage of AI files is they support transparency. AI files have the added benefit of being information-rich - they hold a lot of image data detail, making them easy to edit.įor artwork, AI files can handle more complex images than EPS files. You can scale vectors down to a business card size or up to the size of a billboard and get the same high quality for both. Many designers prefer to use the vector format for certain types of projects due to its precision, quality, and scalability. They’re ideal for scaling because their foundational lines and shapes retain their ratios at any size.ĮPS files can process both bitmap and vector images. Vector graphics use geometry and mathematical proportions - built on a system of points, lines, arcs, curves, and polygons - to create images. When you scale a pixel-based image to a larger size than intended, it won’t have enough pixels to maintain picture quality at the new size. However, pixel-based images are difficult to scale because they consist of many individual pixels. ![]() Each pixel has its own color, which - when combined in large groups - creates a large, detail-rich image. However, because it’s the proprietary file format for Illustrator, most Adobe users still prefer AI.Ī bitmap image is a map of pixels. Today, you can use either EPS or AI files to create both simple and complex drawings, illustrations, designs, and more. It wasn’t until the release of Illustrator 9.0 that Adobe began to move away from the EPS file in favor of the PGF file, which later became the AI file. In its early releases, Illustrator used EPS as its standard file format. Adobe Illustrator debuted in 1987 and quickly became a leader in graphic design software. ![]()
