Resize a picture in Windows


You can change the size or resolution of a digital picture by changing:

  • The number of pixels. The resolution, or sharpness, of a picture is determined by the number of pixels it has. More pixels improve the resolution of a picture, which allows you to make a larger print without reducing visual quality. Keep in mind, however, that the more pixels a picture has, the larger its file size will be.
  • The file size. The amount of space a picture takes up on your computer and how long it takes to send as an e‑mail attachment is determined by the picture's file size. Although more pixels often means a larger file size, the picture's file type (JPEG or TIFF, for example) usually has more to do with file size. For example, a picture saved using TIFF will be much larger than the same picture saved using JPEG. This is because JPEG pictures can be compressed, which makes the file smaller at the cost of slightly lower visual quality.
    If the picture isn't already a JPEG, you can usually save a significant amount of space by saving the file as a JPEG, and then deleting the original TIFF version from your computer. For information about saving a picture as a different type of picture file using Paint, see Change a picture's file type (file format) using Paint.
To resize a picture using Paint

    If the Maintain aspect ratio check box is selected, you only need to enter the horizontal value (width) or vertical value (height). The other box in the Resize area is updated automatically.
  5. Do one of the following in the Resize area, and then click OK:
    • To resize your picture by a certain percentage, click Percentage, and then enter a percentage to reduce the width by in the Horizontal box or a percentage to reduce the height by in the Vertical box.
    • To resize the picture so it's a specific size, click Pixels, and then enter a new width in the Horizontal box or new height in the Vertical box.
  6. Click the Paint button Picture of the Paint button, point to Save as, and then click the picture file type for the resized image.

Algunos trucos para LaTeX



Aquí van algunos truquillos para la inmensa minoría que se está iniciando en el mejor sistema de composición tipográfica jamás creado:LaTeX. Espero que les sea útil.
  • Control de viudas y huérfanas. Para el que no lo sepa, las viudas y las huérfanas son aquellas líneas de principio o fin de párrafo que se quedan solas al final o al inicio de una página, dando un aspecto feo y tipográficamente incorrecto. Curiosamente, LaTeX no penaliza por defecto estas líneas. Para que lo haga, basta con escribir en nuestro preámbulo las siguientes órdenes: 
          \clubpenalty=10000
          \widowpenalty=10000
           ...y no habrá viuda o huérfana que se le resista.
  • Establecer sangría de primera línea. Esta sangría en LaTeX es por defecto un poco más larga de lo que la tradición tipográfica española prescribe (1em, es decir, el tamaño medio de la fuente y que equivale a la anchura de la letra "m". También se conoce esta medida como "cuadratín"). Bueno, si a alguien le quita el sueño este comportamiento, declararemos en nuestro preámbulo una nueva sangría de primera línea:


          \setlength{\parindent}{1em}
  • Usar letras capitulares. Basta con echar mano del paquete "lettrine", incluido en TeXLive y MikTeX. Un ejemplo de uso:


          \lettrine{E}n un lugar de la Mancha...
           En fin, eso es todo. Ya caerán más trucos.
