The last set of options will help you carefully examine color replacement areas and explore other GIF properties. The "Pause One Frame" option lets you pause the GIF and view any frame in detail. When the background color is changed, the changed GIF animation can be looped in the preview window through the "Loop All Frames" option. By default, the score is 10, which means 10% of similar color tones will be matched among the selected color. To expand the range of colors you will be replacing, you can increase the fuzzy color match score. If you don't know the color's name or code, you can use the color-picker helper tool and pick colors from a color palette. The special color name "transparent" can be used to specify transparency. You can also use a hex code, such as "#008000" or an RGB code, such as "rgb(255, 192, 203)". To replace the color of an input GIF, use the options and enter the color's name. You can add a solid color background to a transparent GIF, remove a solid color background from a GIF and make it transparent, or change one background color in a GIF with another color.

One by one loop through the frames, then dump back bytes to the file. of the wanted transparent color, then enter the index in the specific field (which is a Byte) accordingly.

(2) Find out from the global or the local pallete entries (within the boundary of the No of global or the No of local entries as the case may be) what is the index No. (1) Change the frame's "use transparent color" flag to "Yes". If "Yes", nothing further to be done for this frame. Establish whether this frame is coded to "use transparent color". of local palette entries (will be of use). Establish whether a specific frame uses global palette, if it says "No", Local Pallete exists, obtain the No. of global palette entries (will be of use) Ascertain whether Global Palette exists The answer is "Yes" on the premise that one is familiar with the GIF file structure, as the job will entail, e.g. If hImg 0 Then Call GdipDisposeImage(hImg)Ĭan we make the background of an animated gif transparent ?Ĭan we do that in VB without the use of an intermediary transparent container or third party libraries?
