Create Slack-optimized animated GIFs by assembling programmatically generated frames with PIL and numpy, then using a GIFBuilder utility to apply dimension, color quantization, and frame-rate constraints. This ensures the output meets Slack's specific media requirements.

Slack emoji GIFs are typically constrained to 128x128 pixels, while larger message GIFs can be 480x480. Validators check these dimensions along with file size and frame count to verify Slack readiness before sharing the animated graphics.

Validate Slack readiness by running the GIF through built-in validators that check dimensions, file size, and frame count against Slack's media guidelines. This automated verification prevents upload failures and ensures compatibility.

Apply easing functions to frame animations using the provided frame helpers and easing concepts built on PIL and numpy. This allows you to design polished, custom animations rather than simple linear frame transitions.

Yes, the GIFBuilder-based assembly supports both 128x128 emoji-sized GIFs and larger 480x480 Slack stories. It adjusts color budgets and frame rates automatically to match the specific constraints of each output format.

Slack GIFs fail requirements when color budgets exceed limits or frame counts are too high. The quantization and validation utilities identify these issues by checking file size, dimensions, and frame rate against Slack's specific media constraints.
