Solução de formato de arquivo Adobe Photoshop
APIs de alto código e aplicativos gratuitos para PSD, PSB com capacidade de reduzir o tamanho dos arquivos e compactar usando possibilidades não documentadas
Reduzir o tamanho dos arquivos PSD
Reduzir o tamanho de um PSD grande é uma operação simples se você usar o Aspose.PSD. A redução do tamanho pode ser arquivada removendo os dados de cache dos arquivos PSD, mesclando camadas e convertendo para o formato PSD com a menor quantidade de bits por cor. Além disso, você pode alterar o modo de cor do arquivo PSD, por exemplo, mudar da cor CMYK para a cor RGBA reduz o tamanho do arquivo PSD. Este aplicativo usou recursos não documentados do formato PSD, portanto, o resultado final pode ser quebrado. Use o PSD File Reduce somente se você souber claramente o que deseja arquivar.
