Abstract: A compressed font file including compressed data is received. The compressed data is decompressed to generate decompressed data. An attempt to validate the decompressed data is made. Within the decompressed data, a predetermined pattern of invalid data corresponding to an element of a font file is detected. The font file is reconstructed by replacing at least some of the invalid data with the element.

Abstract: A method for storing information may include determining whether a received data object fits inside a particular one of a plurality of free blocks in a memory bitmap. Each of the plurality of free blocks may include a column of the memory bitmap with a top margin, a bottom margin, and a predetermined width. If the received data object fits, the received data object may be stored in the particular one of the plurality of free blocks, starting at the margin of the particular one of the plurality of free blocks. The particular one of the plurality of data blocks may be resized by moving the margin to start below or next to the stored received data object. The determining may include, for each of the plurality of free blocks, a height of the received data object may be compared with a height of each of the free data blocks.

Abstract translation: 用于存储信息的方法可以包括确定接收到的数据对象是否适合存储器位图中的多个空闲块中的特定一个。 多个空闲块中的每一个可以包括具有顶边距，底边距和预定宽度的存储位图的列。 如果所接收的数据对象适合，则接收的数据对象可以存储在多个空闲块中的特定的一个空闲块中，从多个空闲块中的特定一个空闲块开始。 可以通过移动余量来开始多个数据块中的特定一个数据块，以开始在所存储的接收数据对象的下面或旁边。 对于多个空闲块中的每一个，确定可以包括将接收到的数据对象的高度与每个空闲数据块的高度进行比较。

Abstract: A request for a font file including a first font table and a second font table is received. A first entropy encoder is selected, based on characteristics of the first font table, front among a plurality of entropy encoders. A second entropy encoder is selected, based on characteristics of the second font table, front among the plurality of entropy encoders. The first entropy encoder is applied to the first font table. The second entropy encoder is applied to the second font table. Compressed data corresponding to the first and second font tables are combined to generate a compressed font file. The compressed font file is transmitted.
