Hej hcma catbody, jeg er ikke pro bruger af sitet så dine links hjælper mig ikke, jeg har paintshop pro.

Paint Shop Pro lets you assign a transparent value to any color in the image palette. This is useful when working with certain file formats, such as GIF and PNG. You can make any color from the image or the current background color transparent. Note that the image must be paletted before you can use this command.

Paint Shop Pro has a Transparent GIF Saver that makes it even easier to create transparent GIFs. Choose File > Export > Transparent GIF, and use the options in the tabs to set the image transparency. If you prefer to have the program guide use through the process, click the Use Wizard button at the lower left of the dialog box.
To assign a transparent color:

1    Choose Colors > Set Palette Transparency. The Set Palette Transparency dialog box opens.

2    Set the transparency by selecting the appropriate option:

·    To undo the transparency of a color, select No transparency.

·    To assign the background color, select Set the transparency value to the current background color.

·    To assign a color by palette number, enter the number in the palette entry box. The corresponding color appears in the color box.

·    To select a color directly from the image, move the cursor over the image. It becomes the Dropper tool. Click the image to select a color. The third option is chosen, the palette entry box displays the new color’s palette number, and the color box displays the new color.

3    To view the transparency before applying it to the image, click the Proof button. Paint Shop Pro removes the color from the image.

4    Click OK to close the dialog box and make the selected color transparent.
