Import/Export & ImageMagick
|
|
|
|
Import/Export is currently hardcoded to use ImageMagick and the RGB colormodel.
|
|
Additionally, export is broken and even when working, only supported exporting
|
|
to images with one layer.
|
|
|
|
Kimgio is not suitable for Chalk since it only supports importing images as one
|
|
QImage.
|
|
|
|
The new design should support plugins instead of hardcoded filters, so we can
|
|
add an ImageMagick plugin, an openExr plugin or any other kind of image readers.
|
|
|
|
Issues:
|
|
|
|
* conflicts -- more than one plugin might want to support JPEG, for instance.
|
|
* configuration -- compression settings, optional flattening, adding
|
|
profiles, colorspace conversion
|
|
* identification -- no sane way to distinguish a particular type of tiff from
|
|
another type, for instance.
|
|
* colormodel integration -- basically, there are cmyk, rgb and grayscale
|
|
images in a variety of bit depths (e.g., openexr supports 16 bit and half).
|
|
Colorspaces must interpret the file data to build Chalk pixels and must
|
|
unpack chalk pixels to a format a file exporter (e.g, ImageMagick pixel
|
|
packets) can work with. This means that plugins can depend on the presence
|
|
of other plugins.
|
|
* Import/export should be lossless -- i.e., all extra information any file
|
|
format may attach to the image should be kept around and used on export.
|
|
Examples are Exif data and profiles, but also Gimp comments.
|
|
|
|
|
|
KisAnnotation contains metadata about an image that is grabbed from
|
|
a file, such as exif data or TIFF tags and that we should be able to save.

KisAnnotation

KisAnnotation(QString type, QString annotation);
