Re: [MACTCL] Issue with image bitmask support

[Trevor W. <pha...@me...>]

Here’s a test script.  If the script works correctly, the image should be green ‘C’ shape with blue on the inside of the C shape and white on the outside. If the script fails, image will not contain any blue on the inside of the C.  I am only seeing this issue on the Mac (version 8.5.18).  It appears to work with 8.5.8 but broken in 8.5.9.  I verified that at least 8.5.15 on a Kubuntu 15.04 system appears to render the graphic properly.

set data "#define left_width 8\n#define left_height 20\nstatic char left_bits\[\] = {\n0xc0, 0xf0, 0x38, 0x0c, 0x06, 0x06, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x06, 0x06, 0x0c, 0x38, 0xf0, 0xc0};"

set mask "#define left_mask_width 8\n#define left_mask_height 20\nstatic char left_mask_bits\[\] = {\n0xff, 0xff, 0x3f, 0x0f, 0x07, 0x07, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x03, 0x07, 0x07, 0x0f, 0x3f, 0xff, 0xff};"

set img [image create bitmap -data $data -maskdata $mask -foreground green -background white]

pack [label .l -image $img -borderwidth 0 -background blue] 



Thanks,
Trevor
