WIDTH
HEIGHT
MIP_MAPPED
MAINTAIN_RATIO
ALPHA_VALUE

best wishes to all

Hi Flavio,

X - lower left corner X coordinate of the image
Y- lower left corner Y coordinate of the image
WIDTH - size of the image in projection coordinates units
HEIGHT - size of the image in projection coordinates unts
MIP_MAPPED - if the image appears white, activate this option to solve the problem
MAINTAIN_RATIO - calculate the X or Y image size based on the Y or X size (calculated through the number of pixels)
ALPHA_VALUE - transparency value

Hope this helps,
Luis
