How to make a GIF inside a picturebox transparent

Does anyone knows how to make an animated GIF inside a picturebox transparent, so the background of the form can be seen?

    After many unsuccessful attempts this is how I did it and it is working like a charm. I have 8 animations running at the same time in the same form.

    First test that the GIF animation does not have a transparent background by dropping a picturebox into VB.NET form and selecting a GIF for the image property, then select property: BACKCOLOR / WEB / TRANSPARENT, the GIF animation will start playing in the designer and you could see immediately if its background is transparent or not.

    If it is not these are the EASY steps to make it transparent:

    1. Download a free 60 days demo copy of Paint Shop Pro 8 (it comes with Animation Shop 3)
    2. Start the programs and select; File > Jasc Software > Launch Animation Shop
    3. Open the GIF in Animation Shop and select; Edit > Select All > Copy
    4. Move to Paint Shop Pro 8 and select; Edit > Paste > As Animation As Multiple Images
    5. Pick any of the images and click on icon named GIF Optimizer on opened window click on Use Wizard > Use Matching Color To Transparent > choose the color if the background and select the defaults provided until the wizard is finished.
    6. Do the same with all the rest of the images.
    7. Go back to Animation Shop and click on Animation Wizard
    8. Accept all the defaults provided until the wizard is finished
    9. Saved your new transparent GIF animation to the Bin folder of your VB.NET solution

    Write the code below and voila!!!

    Hope this help. Let me know


    Private pbWaterDropsFast As New PictureBox
    Private WaterDropsFast As Bitmap

    WaterDropsFast = New Bitmap("WaterDropsTransparent.gif")
    With pbWaterDropsFast
    .SizeMode = PictureBoxSizeMode.AutoSize
    .Location = New Point(724, 96)
    .Image = WaterDropsFast
    .BackColor = System.Drawing.Color.Transparent
    End With

  • picis mate how do u do it with a bmp???

    Oh, there's an easier way than downloading that software and going through all those steps. I've done it a few months ago. It will work with GIF and BMP, I tested it on both.

    There is a selection somewhere to make a certain color the transparent color. When you put the picture on your form, look through the things it lets you modify. I forget which it was, but I could tell the program to make a certain color transparent. You DO need to know the exact color, in RGB. For example, blue is (0,0,255) and green is (0,255,0).
    When you make the GIF or BMP in your paint program, make the background or whatever part of the picture you want to be transparent exactly this color. Any other shade, no matter how close it is to this color, will not be transparent.
    This is great for drawing things that require layers. In my game, I have tiles for the ground, and on top of that I have tiles with partial transparency like trees, rocks, animated characters etc.

    If you continue having trouble with this, repost. I'll see if I can dig up the exact code I used to make the transparency.
