You can specify part of the image to modify in addition to a text\ndescription of the updates (mask-base editing), or you can use a text prompt to\nupdate the entire image (mask-free editing).\n\nTypes of available editing tools\n--------------------------------\n\nThe following are types of editing that Imagen supports:\n\n- **Mask-based editing** - Lets you specify a targeted area to apply edits to.\n This method of editing is good for edits that apply to only parts of an\n image. Mask-based editing is useful for the following types of image edits:\n\n - [Insert objects into an image](/vertex-ai/generative-ai/docs/image/edit-insert-objects)\n - [Remove objects from an image](/vertex-ai/generative-ai/docs/image/edit-remove-objects)\n - [Expand the content of an image](/vertex-ai/generative-ai/docs/image/edit-outpainting)\n - [Replace the background of an image](/vertex-ai/generative-ai/docs/image/edit-product-image)\n- **Mask-free editing** - Lets you edit an image without a mask (specific\n area). This method of editing is good for edits that belong to the entire\n image, or when the location of the edits is not as important for your use\n case. For location-specific editing, use mask-based editing.\n\n For more information, see [Edit images using text prompts](/vertex-ai/generative-ai/docs/image/edit-images).\n\nLocations\n---------\n\nA location is a [region](/about/locations) you can specify in a request to\ncontrol where data is stored at rest. For a list of available regions, see [Generative AI on Vertex AI locations](/vertex-ai/generative-ai/docs/learn/locations-genai).\n\nSafety filtering\n----------------\n\nBoth input data and output content are checked for offensive material when you\nsend an image editing request to Imagen. This means offensive\ninput data from a text prompt or from a base image you provide can be blocked.\nSimilarly, offensive output images might also be blocked, affecting the number\nof generated images you get in a response.\n\nFor more information about safety filtering and blocked content handling, see\n[Responsible AI and usage guidelines for\nImagen](/vertex-ai/generative-ai/docs/image/responsible-ai-imagen#safety-filters).\n\nModel versions\n--------------\n\nThere are multiple image generation models that you can use. Each model may have\nlimits that are specific to that model. For more\ninformation, see [Imagen\nmodels](/vertex-ai/generative-ai/docs/models#imagen-models).\n\nWhat's next\n-----------\n\n- [Insert objects into an image](/vertex-ai/generative-ai/docs/image/edit-insert-objects)\n- [Remove objects from an image](/vertex-ai/generative-ai/docs/image/edit-remove-objects)\n- [Expand the content of an image](/vertex-ai/generative-ai/docs/image/edit-outpainting)\n- [Edit product images](/vertex-ai/generative-ai/docs/image/edit-product-image)\n\n- [Edit images using text prompts](/vertex-ai/generative-ai/docs/image/edit-images)."]]
