gm.Thumb default output to JPG lost PNG transparent background

yinhm opened this issue · 1 comments

in gm.go file: gm.Thumb func default output to JPG,

line 125        fmt.Sprintf("JPG:%s", outfile),

This would lost PNG transparent background, should we keep image format as it is?

This should be solved by pull request #52, which is now merged 😄
