Base64 string to Texture2D problem

Found it :slight_smile:

when you convert base64 data image is a byte array containing the JPG OR PNG FORMAT is not a FColor array.

you can create an texture directly by using :

FImageUtils::ImportBufferAsTexture2D(BGRA8PixelData);

and also you need send only the base64 data , so you need to extract data:image/png;base64,

UTexture2D* ATcpSocketConnection::Base64_ToImage(FString Source)
{
	TArray<uint8> data_buffer;
	FString Left, Right;
        // you need to remove Data:image....,
	Source.Split(TEXT(","),&Left,&Right);
	if (Right == "") return nullptr;
	bool isDecode = FBase64::Decode(Right, data_buffer);
	if (isDecode) {
		return CreateBitTextureAtRuntime(data_buffer);
	}
	else {
		return nullptr;
	}
}


UTexture2D* ATcpSocketConnection::CreateBitTextureAtRuntime(TArray<uint8> BGRA8PixelData)
{
	UTexture2D * Texture = FImageUtils::ImportBufferAsTexture2D(BGRA8PixelData);
	Texture->MipGenSettings = TMGS_NoMipmaps;
	Texture->CompressionSettings = TextureCompressionSettings::TC_VectorDisplacementmap;
	Texture->MipGenSettings = TextureMipGenSettings::TMGS_NoMipmaps;
	Texture->SRGB = false;
	Texture->Filter = TextureFilter::TF_Nearest;
	Texture->UpdateResource();
	return Texture;
}

hope it’s help :slight_smile:
Have a nice day
