Overview
Se concluye que independientemente de la herramienta que se utilice, es el formato de la imagen lo que influye en el tamaño final.& The objective was to determine the influence of different image formats and tools used for compression on the final size of the images, to know which are the optimal formats for compression. The sample was made up of five digital image files with BMP extension, taken in different scenarios and at different times at the researcher's discretion. The technique used was the analysis of digital image files and as an instrument a double input matrix, where the conversions of BMP files to six different extensions of image files were registered, with four different tools for manipulation of image files. The experimental design was factorial, where the two factors were the image compression formats and tools and the dependent variable the final image file size. Factorial ANOVA statistical analysis was applied with a = 0.05. It was obtained that the format of smaller size was the JPG when using as tool the Illustrator and the one of greater size the one of greater extension the PSD also obtained with the Illustrator. The statistical analysis showed that the format factor significantly influences the final size of the images (p < 0.05) and the tool factor does not show significant influence on the size of the images (p > 0.05), nor is the interaction between the factors significant. It is concluded that regardless of the tool used, it is the image format that influences the final size. El objetivo de este trabajo fue el determinar la influencia de diferentes formatos de imagen y herramientas que se utilizan para la compresión en el tamaño final de las mismas, para conocer cuáles son los formatos óptimos para la compresión. La muestra estuvo conformada por cinco archivos de imágenes digitales con extensión .bmp, tomadas en diferentes escenarios y horas a criterio del investigador. La técnica empleada fue el análisis de archivos de imágenes digitales y como instrumento una matriz de doble entrada, donde se registraron las conversiones de los archivos .bmp a seis diferentes extensiones de archivos de imágenes, con cuatro diferentes herramientas de manipulación de archivos de imágenes. El diseño experimental fue factorial, donde los dos factores fueron los formatos y las herramientas de compresión de imágenes y la variable dependiente, el tamaño final del archivo de imagen. Se aplicó análisis estadístico ANOVA factorial con a = 0,05. Se obtuvo que el formato de menor tamaño fue el .jpg al utilizar como herramienta el Illustrator y el de mayor tamaño el .psd, también obtenido con el Illustrator. El análisis estadístico mostró que el factor formato influye de forma significativa en el tamaño final de las imágenes (p < 0,05) y el factor herramienta no muestra influencia significativa en el tamaño de las imágenes (p > 0,05), como tampoco es significativa la interacción entre los factores. Se concluye que independientemente de la herramienta que se utilice, es el formato de la imagen lo que influye en el tamaño final.
