Unwanted Pixels in zt picture

Jay,

You had posted at one time, an answer to how to prevent or remove the unwanted white pixels from a gimp picture before inserting it into zoot. Can you post that again? Thanks

There are many possible causes to getting unwanted white pixels. Two of those causes in GIMP involve reducing the number of colors of an image and not changing the top leftmost pixel after other GIMP operations. Here is my post that talked about how to do those in a way that do not cause unwanted pixels:

If you have white (or any other color) pixels that you want to become transparent, and there are no other pixels that you want to leave at that color, you can do the following in GIMP:
Click the Select by Color Tool, set Threshold to 0 (if you only want a specific shade of that color to become transparent), click on one of the pixels you want to become transparent (which selects all pixels of that color), click the Foreground color rectangle, set "HTML notation" to ff00ff in the Change Foreground Color window and click OK (which sets the current color to that magenta color most people use for the background color of ZT images), click the Bucket Fill Tool, click the circle next to "Fill whole selection", click on one of the selected pixels to set all of the selected pixels to magenta, and press the Delete key to turn it to transparent. The Color Picker Tool can be used to confirm the transparent color used to be magenta. Neither Zoot nor APE understand transparency; they look at what the color used to be. To be safe, before saving into a ".png", I always change all other transparent colors to magenta and make them transparent again, since GIMP often changes the transparency color from magenta to black. Steps 8 and 9 in the above post say how to do that. If there are some white pixels you want to keep as white, you would have to change the unwanted white pixels 1 by 1, which is why trying to prevent unwanted pixels is usually preferred to trying to remove unwanted pixels.

Thanks Jay. I just wasn't able to find it in the questions area which I thought was where it was posted for Maxx.
