Obviously, if GDI saves a GIF, it does not create a new palette. The best you can ever do is use something to limit the compression to attempt to keep the integrity of the file. The only task is creating the palette accordingly. Answer (1 of 3): In a fairly real sense, you can’t. So any image that contains a maximum of 256 different colors can be represented by a GIF.
Batchphoto reduce quality code#
So I will try to find some reusable code that does the conversion. However, for some cases it would be a solution to create an PNG8. It is more than just calling a GDI function ConvertToIndexedAndTryTheBest. We have 150+ professionals and experienced graphic designers/artists, who will always be ready to provide the highest quality image. I looked into converting a Format32bppArgb into a Format8bppIndexed. The transparent areas should stay transparent.Īctually, I am no GDI guru at all.

Now I want to reduce the bitmap's quality.There are many filled pixels in the image, but there are also transparent areas.There is a bitmap in memory, 4 channels, ARGB.However, it is not, because the alpha gets lost.
Batchphoto reduce quality software#
This "saving to a file and reading into bitmap" would be the solution. Introducing BatchPhoto, a photo size reducing software for Win & Mac.

Almost the same as saving the JPG to file and then reading it again into memory. My actual question was "can I simulate that quality reduction feature in memory"? Is there some GDI function, taking a bitmap and reducing its quality. I was not to mean that I have a JPG and want to to something with it. It was simply an introduction into my question. In my original post I mentioned JPG and its "quality reduction" feature, which can be used in GDI by means of ImageCodecInfo and EncoderParameters. Probably I should take some English lessons "describing a technical question clearly".
