Image conversion methods

摘要

Methods and apparatus for image conversion are provided. A computing device can receive image data having line(s) of pixels encoded using a first format. The first format can specify a repeat count for a corresponding line of pixels. The computing device can convert the image data from the first format to a second format. The conversion can include: for a designated input line, determining whether the repeat count for the designated input line is greater than one; and after determining that the repeat count is greater than one: generating a designated output line encoded in the second run-length encoded format that corresponds to the designated input line, and duplicating the designated output line a number of times based on the repeat count. The computing device can provide an output comprising the image data encoded in the second format.

主权项

1. A method, comprising:
receiving image data encoded using a first run-length encoded format, wherein the image data comprises one or more lines of pixels, and wherein the first run-length encoded format comprises a repeated-line code specifying a repeat count; performing a conversion of the image data from the first run-length encoded format to a second run-length encoded format, wherein the second run-length encoded format differs from the first run-length encoded format, and wherein performing the conversion comprises:
for a designated input line of the image data encoded in the first run-length encoded format, determining whether the repeat count for the designated input line is greater than one; andafter determining that the repeat count is greater than one,
generating a designated output line that is encoded in the second run-length encoded format and that corresponds to the designated input line, andduplicating the designated output line a number of times, wherein the number of times is based on the repeat count; and providing an output comprising the image data encoded in the second run-length encoded format.
