Values

jpg → const OutputFormat

JPG (JPEG)

  • Compression: Lossy
  • Quality: Lower quality due to lossy compression, but high enough for most photographic images.
  • File Size: Generally small due to compression.
  • Use Case: Web images, digital photos, where small file size is important and some quality loss is acceptable.
png → const OutputFormat

PNG (Portable Network Graphics)

  • Compression: Lossless
  • Quality: High quality with no loss of data, supports transparency (alpha channel).
  • File Size: Larger than JPG due to lossless compression.
  • Use Case: Images requiring transparency, web graphics, icons, and images where quality is important.
tiff → const OutputFormat

TIFF (Tagged Image File Format)

  • Compression: Both lossless and lossy (usually lossless).
  • Quality: Very high quality, suitable for professional photography and printing.
  • File Size: Very large, especially with lossless compression.
  • Use Case: Professional photography, desktop publishing, scanning, and archival storage.
bmp → const OutputFormat

BMP (Bitmap)

  • Compression: None or lossless
  • Quality: Very high quality with no loss of data.
  • File Size: Very large, as it stores image data without compression.
  • Use Case: Simple graphics and images on Windows platforms, where file size is not a concern.
cur → const OutputFormat

CUR (Cursor)

  • Compression: Typically none
  • Quality: Varies, usually optimized for small size and simplicity.
  • File Size: Small, designed for cursors.
  • Use Case: Mouse pointers/cursors in Windows operating systems.
pvr → const OutputFormat

PVR (PowerVR Texture)

  • Compression: Lossy and specialized for texture compression
  • Quality: Varies based on compression level; optimized for use in graphics rendering, especially in games.
  • File Size: Generally small, efficient for textures.
  • Use Case: Texture maps in 3D graphics, especially in mobile and console games.
tga → const OutputFormat

TGA (Targa)

  • Compression: None or lossless
  • Quality: High quality, supports alpha channels.
  • File Size: Larger due to optional compression.
  • Use Case: Video game textures, simple animations, and image processing where alpha channel is needed.
ico → const OutputFormat

ICO (Icon)

  • Compression: Typically none or simple RLE (Run-Length Encoding)
  • Quality: Varies; can include multiple sizes and bit depths.
  • File Size: Small, optimized for icons.
  • Use Case: Icons for software applications and operating systems.
