Abstract

To create a thumbnail version of an image associated with respective content (e.g., a web page), a computer process herein receives an identification of content formatted according to a first format. Based on the identification of the content to be converted into a thumbnail, the computer invokes a first service to utilize the content formatted according to the first format (e.g., HTML) and produce a rendition of the content according to a second format (e.g., a PDF format). The computer then invokes a second service to produce a rendition of the content according to a third format based on the rendition of the content according to the second format. The format of the thumbnail has a lower resolution compared to a respective imaging resolution associated with the PDF format to reduce network resources required to transfer the thumbnail rendition of the content to other users in a collaborative whiteboard session.

Claims

receiving an identification of content formatted according to a first format;

based on the identification of content, invoking a first service to utilize the content formatted according to the first format to produce a rendition of the content according to a second format;

invoking a second service to produce a rendition of the content according to a third format based on the rendition of the content according to the second format, the third format supporting reduced resolution thumbnail imaging of the content compared to a respective resolution supported by the second format;

initiating display of the rendition of the content formatted according to the third format to collaboration windows of members in a collaboration system; and

wherein the identification of content is a content identifier and wherein receiving the identification of content occurs in response to a first member of a collaborative whiteboard session in the collaboration system dragging and dropping a visual rendition of the content identifier onto an editable whiteboard for sharing the content as specified by the content identifier with a second member of the collaborative whiteboard session, the second member being at a remote location with respect to the first member;

wherein invoking the first service includes converting the content into a PDF (Portable Document Format) viewing format; and

wherein invoking the second service includes converting the content formatted according to the PDF viewing format into a thumbnail rendition of the content, the thumbnail rendition of the content having a reduced resolution format compared to a resolution of the PDF viewing format.

2. A computer-implemented method as in claim 1, wherein invoking the second service to produce the rendition of the content according to the third format results in generation of a thumbnail rendition of the content requiring less memory resources for storage than respective memory resources required to store the rendition of the content according to the second format.
