Antetype uses the sRGB color space to store all color information (since version 1.1.8). The sRGB color space has been chosen because it is display, device and operating system independent and ideal for managing colours that are to be displayed on a computer screen rather than printed.

In order to make sure that all color information is stored in sRGB all color references that are passed to Antetype must be converted to the sRGB color space.

Images

When an image is imported into Antetype it is automatically converted to the sRGB color space and stored as an image with an sRGB color space. This means that the colors in an image are all converted from their original values to the equivalent values in the sRGB color space. The conversion process in most circumstances will be loss less, but there may be circumstances where color information will be lost. If you are encountering problems with the colors of an imported image the best suggestion is to make sure that the image is saved directly with an sRGB profile when it is generated.

It is not possible currently for us to change the color space of PDF files that are imported into Antetype if you import PDF images you may encounter color mismatches still, in these circumstances we would recommend using a bitmap format to import the images, or manually ensure that the contents of the PDF are in the sRGB color space.

Color Panel

The most common way to set colors in Antetype is via the OS X standard color panel. The color panel provides various ways for a user to chose a color: OS X standard color pickers, 3rd party color pickers and via the magnifying glass to directly sample a color from the screen. These methods do not always result in an sRGB color being sent to Antetype and in circumstances where a non sRGB color has been chosen Antetype automatically converts the color to sRGB. This conversion process can result in the controls in the Color Panel "jumping" as the chosen color is altered to an sRGB equivalent.




In an OS X application using the magnifying glass to sample colors from the display does not function as might be expected. The color values that are sampled by the magnifying glass are in the color space of the display and therefore differ depending on the display used when sampling. To make color sampling more accurate and consistent Antetype converts the sampled values into sRGB unfortunately some information can be lost in the reverse conversion to sRGB. Depending on the color space of the display the colors sampled with this method may not always match a sRGB color that has been manually set.

For users with OS X 10.8 or higher Antetype is able to sample with 100% accuracy when the magnifying glass is used sample a color from an Antetype window. We have modified the color panel so that it always returns the exact sRGB that was set within Antetype, this is done without conversion and therefore no information is lost during the process.

Antetype Color Picker

An optional third party color picker (shown in the image above) that has been developed by the Antetype team can be installed from the preferences panel within the application.

Exporting images

All images that are exported from Antetype are exported in the sRGB color space, this can be done either with or without the color space profile information being attached to the image.

Exporting an image without a color space profile reduces the size of the image and if the image is to be viewed on a mobile device (iOS, Android or Windows Mobile) or in a web browser (Safari, Internet Explorer, Firefox or Chrome) it will be rendered with an assumption that the color space is sRGB.

Where there is a need to embed the color space profile in the exported image this can be done but will increase the size of the image, use this option if you will edit an image further in image editing software.

File format

The file format used by Antetype 1.1.8+ stores color information in a new format and expects all images to be in the sRGB format. This means that files edited in a prior version of Antetype must be upgraded to the new format this upgrade is handled automatically the first time that an older file is opened in Antetype.

During the upgrade process a copy is made of the original file and places in the OS X trash to be retrieved if for some reason you need to access the pre-upgraded file.
