Transparent jpg in one file?

(Nirvan) #1

Hi all, I have image like this: http://imageshack.us/a/img811/5332/nw5h.png But in png this file is very large. If there is possibity to make transparent image from this: http://imageshack.us/a/img20/555/gplr.jpg to convert black pixels to transparent. size of game will be much lower. ( I know about png optimization but lowest size will be 150 with lower quality ) Exists this possibility?

Thanks.

Edit: Ok I can load jpg file and then set image blend to “add” but with this render time will not be much slower? Because previously when I was using add blend mode render time was bigger.

You can set an Image's drawMask property to your image, and this should make areas that are black fully transparent and areas that are white fully opaque.

sligthly offtopic: flash can store PNGs in lossy compression internal formats (JPEG if I am correct). there was a reducer tool created by joa ebert, but now it seems to evolved into sth more called “apparat”. https://github.com/joa/apparat with this you can reduce size of SWF by forcing lossy compression to all store bitmaps.
