Can You Get Syphilis On Back Of Tongue

electronic books mp3 players



The release of devices like the Kindle, iPad and a host of readers of books, have renewed interest in the books.
Consumer prices of these readers in general are above $ 100.

You can read digital books on devices more economical?

The answer is yes, assuming you have no problem in sacrificing image quality, you can actually read text on tiny screens such as those in MP3 players or digital cameras.
In fact, some newer MP3 players already have software to read eBooks.

Without having these players, we decided to do an experiment to see if you can download a book in a media player that is not originally designed to read e-books.

The following are the steps taken and results achieved.

A first step was to obtain fonts (fonts) small, so you can put much text on a tiny screen. In this experiment we use a free source called 04b03.

A second step was to convert text to images, (The player in question, insignia ns-4v17b, has the ability to play JPG on a small screen of 220 x 176 pixels).

In theory this should be easy, and think that maybe there is software that makes it automatically. We did not find anything. A program that seemed appropriate for this task is ImageMagick, which can convert text to images, but in practice this software is not easy to convert long texts on small images. (It may be possible if a pre-formatted text using some script)

Finding no suitable software, we decided to write a visual basic program that performs the following tasks:

1. Open a text file (downloaded from Project Gutenberg ) and load the text line by line.
2. Make the "word wrap" with a certain number of columns to ensure that the text in the image.
3. Print the text in parts in a box of images (PictureBox) using the font tiny.
4. Save each image in a separate BMP file of 220 x 176 pixels.

then proceeded to upload the images to the mp3 player (This is done using the utility that comes with the CD player)

After several attempts and calibrations we carry an entire book on mp3 player. The images are saved in JPG format, which is somewhat inefficient but no problem because the player has 4GB of memory.

The end result?

Very satisfying!
The generated pages are quite readable (see photo above), but could use a magnifying glass to avoid eyestrain.

Another experiment was to reformat the images to be seen in a camera. This requires generate JPG format to comply with DCF. A free program that does this is Image Creator, which was developed for use with Panasonic digital projectors. Instructables In explaining the steps .
The method works, but the program does not give too many chances to reduce the resolution of the images, which end up being quite large in relation to the resolution of the display of the camera.

In conclusion, the method is feasible and economical that many devices have a screen (cameras, MP3 players, digital photo viewers, etc.) can be used to read e-books. Obviously the most efficient is that the devices run software that directly display TXT files, which is already happening, for example in the folowing devices: Jwin

All these are very economical and cost between 20-30 dollars on Amazon
