-## Important 
-
-**By default, the PSX will consider black pixels (0,0,0,0) as transparent**.  
-In order to display those black pixels as black, you have to set the STP on black (1,0,0,0).   
-Black pixels and non-black pixels with the STP bit will display as semi-transparent when using `SetSemiTrans()`.  
-
-## STP on black 
- 
-Use this to display black pixels as black, not transparent.
-The **inverted** alpha mask of the TIM  corresponds to the position of black (0,0,0) pixels in the image.
-
-```bash
-img2tim -b -org 640 0 -o stpOnBlack.tim av.png
-```
-
-## STP on non-black 
-
-Black pixels will be considered as transparent, and non-black pixels will receive semi-transparency with `SetSemiTrans()`.  
-
-The alpha mask of the TIM  corresponds to the position of non-black (n,n,n) pixels in the image.
-Additionally, a setting allows you to define the RGB value to be considered transparent ; `-tcol` . This does not set any STP flag. 
-
-```bash
-img2tim -t -org 320 0 -o stpOnNonBlack.tim av.png
-```
-
-## Use alpha channel
-
-The alpha mask of the TIM  corresponds to the existing alpha channel of the image (PNG, GIF, TGA, TIFF).
-Additionally, a setting allows you to define the threshold for the alpha value to be considered transparent ; `-alpt` . This does not set any STP flag.
-
-```bash
-img2tim -usealpha -org 640 256 -o stpOnNonBlack.tim av.png
-```
-
-## Use color index
-
-When using 8/4bpp palettized images, you can specify the index number of the color to be considered transparent. This does not set any STP flag.
-
-You can set the STP bit by CLUT color with PsyQ's `TIMTOOL.EXE`. This allows you do do cool stuff like oly having specific colors being rendered as semi-transparent by `SetSemiTrans()`.
-
-```bash
-img2tim -b -bpp 8 -tindex 0 -org 640 256 -plt 0 481 -o stpOnColIndex.tim av8.png
-```
-
-## Black transparency work-around
-
-Using a pseudo-black color with one of the channels value to 10, i.e : `255,255,10` can be done so you dont have to set the STP bit on full black.  
-This allows you to keep the pseudo-black opaque when using `SetSemiTrans()`.
