Hi all  

im making some gauges whit a 8 bit 256 color alpha mask as highlight


and i have some trouble  


image tools do not apcept any image that not a multiple of 2
exp 256,512,1024 etc etc

my 8 bit 256 color alpha mask image was 290 pixel by 290 and i not whant to resize all my gauges

it is posible to resize an image after they have been altered whit image tools ?

and what tool  i need to resize my 8 bit  alpha mask image whit out losing the alpha ?
