Image content components

These components accept an image/* MIME type. Common web and camera formats come first. Download a .wasm file and run it with qipx run, or use the recipe finder to connect compatible decoders, transforms, and encoders.

• jpeg-strip-gps-exif.wasm removes GPS coordinates from EXIF metadata without decoding the image.
• jpeg-to-bmp-b8g8r8a8-srgb.wasm decodes JPEG to an 8-bit sRGB BMP image.
• jpeg-to-ktx2-r8g8b8a8-srgb.wasm decodes JPEG to an 8-bit sRGB KTX2 image.

Related tool: JPEG location stripper.

PNG (image/png) #

• png-to-bmp-b8g8r8a8-srgb.wasm decodes PNG to an 8-bit sRGB BMP image.

SVG (image/svg+xml) #

• svg-rasterize-thorvg-to-ktx2-r8g8b8a8-srgb.wasm uses ThorVG's CPU renderer for broader SVG paint support and antialiased RGBA8 sRGB KTX2 output. This build does not include fonts or embedded raster-image decoders.
• svg-rasterize-to-ktx2-rgba32float-bt709-linear-simd.wasm uses SIMD scanline path coverage with a 4 by 4 sample grid and linear-light compositing, then writes linear BT.709 RGBA32F KTX2.
• svg-rasterize-to-ktx2-r8g8b8a8-srgb-simd.wasm uses the same antialiasing path, then quantizes the completed image to canonical RGBA8 sRGB KTX2.
• svg-rasterize-to-ktx2-r8g8b8a8-srgb.wasm provides the faster center-sampled baseline in canonical RGBA8 sRGB KTX2.
• svg-rasterize-to-bmp-b8g8r8a8-srgb.wasm provides BMP output for stages that still require it.

It preserves paths, groups, affine transforms, supported native gradients, and element/group opacity; unsupported SVG rejects rather than rasterizing.
• svg-to-data-uri.wasm percent-encodes SVG bytes as a data URI.

GIF (image/gif) #

KTX2 (image/ktx2) #

Generate

• solid-color-oklch-to-ktx2-rgba32float-display-p3-linear.wasm generates a straight-alpha linear Display P3 float32 KTX2 surface from width, height, lightness, chroma, hue_degrees, and alpha uniforms. It reduces out-of-gamut OKLCH chroma while preserving lightness and hue.

Resize

• ktx2-rgba32float-display-p3-linear-resize-up-mitchell.wasm enlarges linear Display P3 float32 KTX2 and preserves HDR RGB values.

The components filter in linear light with premultiplied alpha. They expose width and height uniforms, preserve aspect ratio when one dimension is omitted, and recoverably reject the opposite scaling direction.

Rotate and flip

• ktx2-r8g8b8a8-srgb-rotate-and-flip.wasm rotates canonical RGBA8 sRGB KTX2 by right angles and flips it horizontally or vertically without changing channel values.
• ktx2-rgba32float-rotate-and-flip.wasm provides the same operation for linear BT.709, linear Display P3, and transfer-encoded Display P3 RGBA32F KTX2, preserving each profile's metadata.

Both components accept rotation_degrees=0|90|180|270, flip_horizontal=0|1, and flip_vertical=0|1. Rotation is clockwise and happens before either flip.
