imageData probeConfirms whether headless xTalk server can decode an image and expose pixels (spec §7).
| Step | Result | Detail |
|---|---|---|
| decode embedded test PNG (base64) | OK | 75 bytes (expected 75) |
| create invisible image | OK | image control created |
| put PNG bytes into image | OK | no error thrown |
| formattedWidth x formattedHeight | OK | 2 x 2 (expected 2 x 2) |
| imageData length | OK | 16 bytes (expected 16 = 2*2*4) |
| bytes per pixel | OK | 4 |
| pixel (0,0) expected RED | OK | 255,255,0,0 |
| pixel (1,0) expected GREEN | OK | 255,0,255,0 |
| pixel (0,1) expected BLUE | OK | 255,0,0,255 |
| pixel (1,1) expected WHITE | OK | 255,255,255,255 |
| channel byte order (§7.2 = 0,R,G,B) | OK | 0,R,G,B confirmed |
| luminance §7.3 of RED pixel | OK | 63 (=R since r<>g) |
| luminance §7.3 of WHITE pixel | OK | 255 (=255) |
