Dataset Card for Crello

Dataset Summary

The Crello dataset is compiled for the study of vector graphic documents. The dataset contains document meta-data such as canvas size and pre-rendered elements such as images or text boxes. The original templates were collected from crello.com (now create.vista.com) and converted to a low-resolution format suitable for machine learning analysis.

Usage

import datasets

dataset = datasets.load_dataset("cyberagent/crello", revision="5.0.0")

Supported Tasks and Leaderboards

CanvasVAE studies unsupervised document generation.

Languages

Almost all design templates use English.

Dataset Structure

Data Instances

Each instance has scalar attributes (canvas) and sequence attributes (elements). Categorical values are stored as integer values. Check ClassLabel features of the dataset for the list of categorical labels.

To get a label for categorical values, use the int2str method:

data = dataset['train'] # obtain the train set
key = "font"
example = data[0] # obtain the first sample in train set

data.features[key].feature.int2str(example[key]) # obtain the text equivalent of the encoded values

Data Fields

In the following, categorical fields are shown as categorical type, but the actual storage is int64.

Canvas attributes

Field	Type	Shape	Description
id	string	()	Template ID from create.vista.com
group	categorical	()	Broad design groups, such as social media posts or blog headers
format	categorical	()	Detailed design formats, such as Instagram post or postcard
category	categorical	()	Topic category of the design, such as holiday celebration
canvas_width	int64	()	Canvas pixel width
canvas_height	int64	()	Canvas pixel height
length	int64	()	Length of elements
suitability	categorical	(None,)	List of display tags, only mobile tag exists
keywords	string	(None,)	List of keywords associated to this template
industries	categorical	(None,)	List of industry tags like marketingAds
preview	image	()	Preview image of the template for convenience
cluster_index	int64	()	Cluster index used to split the dataset; only for debugging
non_text_preview	image	()	Preview image of the template without text

Element attributes

Field	Type	Shape	Description
type	categorical	(None,)	Element type, such as vector shape, image, or text
left	float32	(None,)	Element left position
top	float32	(None,)	Element top position
width	float32	(None,)	Element width
height	float32	(None,)	Element height
color	string	(None, None)	RGB color palette of the vector graphic element
opacity	float32	(None,)	Opacity in [0, 1] range
image	image	(None,)	Pre-rendered preview of the element encoded in PNG format
text	string	(None,)	Text content in UTF-8 encoding for text element
font	categorical	(None,)	Font family name for text element
font_size	float32	(None,)	Font size (height) in pixels
text_align	categorical	(None,)	Horizontal text alignment, left, center, right for text element
angle	float32	(None,)	Element rotation angle (degree) w.r.t. the center of the element
font_bold	boolean	(None, None)	Character-wise flag to indicate bold font
font_italic	boolean	(None, None)	Character-wise flag to indicate italic font
text_color	string	(None, None)	Character-wise rgba color
text_line	int64	(None, None)	Character-wise index of line number
capitalize	boolean	(None,)	Binary flag to capitalize letters
line_height	float32	(None,)	Scaling parameter to line height, default is 1.0
letter_spacing	float32	(None,)	Adjustment parameter for letter spacing, default is 0.0
font_v3	string	(None, None)	(font_v3, probs) for relavant text
text_html_code	string	()	text html code using font
text_html_code_v3	string	()	text html code using font_v3

left and top can be negative because elements can be bigger than the canvas size. text_line indicates the index of the text line. For example, the following indicates that Be is in the first line and the rest in the next line. The newline character \n if present is ignored in rendering.

{
  "text": "Be\nambitious!",
  "text_line": [0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 1],
}

Note that the color and pre-rendered images do not necessarily accurately reproduce the original design templates. The original template is accessible at the following URL if still available.

Data Splits

The Crello dataset has 3 splits: train, validation, and test. The current split is generated based on appearance-based clustering.

Visualization

Each example can be visualized in the following approach using cr-renderer.

Note the renderer does not guarantee a similar appearance to the original template. Currently, the quality of text rendering is far from perfect.

Dataset Creation

Curation Rationale

The Crello dataset is compiled for the general study of vector graphic documents, with the goal of producing a dataset that offers complete vector graphic information suitable for neural methodologies.

Source Data

Initial Data Collection and Normalization

The dataset is initially scraped from the former crello.com and pre-processed to the above format.

Who are the source language producers?

While create.vista.com owns those templates, the templates seem to be originally created by a specific group of design studios.

Personal and Sensitive Information

The dataset does not contain any personal information about the creator but may contain a picture of people in the design template.

Considerations for Using the Data

Social Impact of Dataset

This dataset was developed for advancing the general study of vector graphic documents, especially for generative systems of graphic design. Successful utilization might enable the automation of creative workflow that human designers get involved in.

Discussion of Biases

The templates contained in the dataset reflect the biases appearing in the source data, which could present gender biases in specific design categories.

Other Known Limitations

Due to the unknown data specification of the source data, the color and pre-rendered images do not necessarily accurately reproduce the original design templates. The original template is accessible at the following URL if still available.

Additional Information

Dataset Curators

The Crello dataset was developed by Kota Yamaguchi.

Licensing Information

The origin of the dataset is create.vista.com (formally, crello.com). The distributor ("We") do not own the copyrights of the original design templates. By using the Crello dataset, the user of this dataset ("You") must agree to the VistaCreate License Agreements.

The dataset is distributed under CDLA-Permissive-2.0 license.
