Image Formats

图像格式

Images and videos can be loaded much easier and faster in Cinema 4D R19, which is important, for example, when working with the Motion Tracker and when using video textures.

在 Cinema 4D R19中，图像和视频可以更容易、更快地加载，这一点非常重要，例如，在使用运动跟踪器和使用视频纹理时。

The following image formats can be loaded (e.g., as a texture in a material) or exported (e.g., as a rendered image):

下列图像格式可以加载(例如，作为材质中的纹理)或导出(例如，作为渲染图像) :

The various image formats and their properties. 各种图像格式及其属性Multi-Pages 多页 is only for import; if multiple entries exist, these are for loading or saving; 只用于导入; 如果存在多个条目，则这些条目用于加载或保存;"i" “我” for bit depth represents indexed colors. 对于位深度表示被索引的颜色

As the table shows, the TIFF format offers the greatest flexibility, which is why this is the most widely used image format in production pipelines (also because it can be compressed loss-free).

如表所示，TIFF 格式提供了最大的灵活性，这就是为什么它是生产管道中使用最广泛的图像格式(也是因为它可以压缩为无损)。

Image formats and maximum resolutions

图像格式和最大分辨率

Cinema 4D can render images with a maximum resolution of 128,000 x 128,000 pixels. However, not all image or video formats can handle this large resolution.

JPEG

Save Options

保存选项

Quality: Defines the JPEG quality.

质量: 定义 JPEG 质量。

B3D

BodyPaint 3D proprietory image format. Saves textures, including all layers, layer masks and alpha channels.

BodyPaint 3D prietory image format。保存纹理，包括所有层，层蒙版和 alpha 通道。

RLA/RPF

The RPF format is a further development of the RLA format. Both formats add numerous channels to the rendered image that can be edited in compositing programs.

RPF 格式是 RLA 格式的进一步发展。这两种格式都向渲染的图像添加了许多通道，可以在合成程序中进行编辑。

Save Options

保存选项

Depending on which options are enabled, corresponding information will be written into the file (RLA has fewer options than the RPF format; functions of the same name work identically).

根据启用了哪些选项，相应的信息将被写入文件(RLA 的选项比 RPF 格式少; 同名的函数工作方式相同)。

  • Subpixel Weight 亚像素权重: Information about sub-pixel color. : 关于亚像素颜色的信息
  • Z: This channel contains information about the camera’s distance from the object and makes it possible to calculate depth of field effects. 这个通道包含摄像机与物体的距离信息，使得计算景深效果成为可能

  • Transparency 透明度: Transparency information for the object. 对象的透明度信息

OpenEXR

A HDR image for mat that can be saved with either 16 (float comma) or 32-bit (float comma/integer) per color channel. OpenEXR is the more current format compared to other commonly used HDR formats (Radiance (HDR)). Furthermore, OpenEXR can contain any number of channels.

每个颜色通道可以保存16(浮点逗号)或32位(浮点逗号/整数)的 mat HDR 图像。与其他常用的 HDR 格式(Radiance (HDR))相比，OpenEXR 是比较通用的格式。此外，OpenEXR 可以包含任意数量的通道。

HDR formats are well-suited for compositing or as Image-Based Lighting (lighting via Global Illumination). See also Color Depth.

HDR 格式非常适合合成或作为图像照明(通过全局光源照明)。

Save Options

保存选项

Comperssion Method: You can select from a range of loss-free or lossy compression methods.

综合方法: 你可以选择一系列的无损失或有损数据压缩方法。

16-bit Float Comma: Saves in a special, less precise float comma format that can be edited faster.

16位浮点逗号: 以一种特殊的、不太精确的浮点逗号格式保存，可以更快地编辑。

Layer Numbering: Disable this option of you don’t want to use the Cinema 4D OpenEXR layer numbering system (_0001, _0002, etc.).

层编号: 禁用这个选项，你不想使用C4D OpenEXR 层编号系统(0001,0002等)。

Radiance (HDR)

辐照度(HDR)

This is the normal HDR image format. Even though this is labeled as 32-bit in the table above, this is not quite correct. HDR tricks a little and uses 8 bits per color channel plus a common exponent. When saving, use one of the other real 32-bit formats.

这是正常的 HDR 图像格式。尽管在上面的表格中将其标记为32位，但这并不完全正确。HDR 略施小计，每个彩色通道使用8位，外加一个常见的指数。保存时，使用另一种真正的32位格式。

PNG

巴布亚新几内亚

A commonly used graphics format with loss-free compression, i.e., the image size can, depending on the scene, be about half or one-third the size of a TIFF image (PNG does not support CMYK as TIFF does).

一种常用的无损压缩图形格式，也就是说，根据场景的不同，图像的大小可以是 TIFF 图像大小的一半或三分之一(PNG 不像 TIFF 那样支持 CMYK)。

Save Options

保存选项

The Interlaced option can be enabled, which produces a result similar to JPEG: these images will be displayed in their entirety much faster in the browser.

可以启用隔行选项，这会产生一个类似于 JPEG 的结果: 这些图片将在浏览器中以更快的速度全部显示。

DPX

An image format commonly used in movie production and used in post-production (i.e., for the processing from camera to projector).

一种常用于电影制作和后期制作的图像格式(例如，用于从摄影机到放映机的处理)。

The following are not supported when loaded:

加载时不支持以下内容:

Save Options

保存选项

The Planar option can be enabled if required by the software in which the image will subsequently be edited. Internally, the color channels will be saved as a single block.

如果随后编辑图像的软件需要，可以启用 Planar 选项。在内部，颜色通道将保存为一个单一的块。

The Bit Depth setting lets you set a color depth of 10 or 12 bits.

位深度设置允许你设置10或12位的颜色深度。

DDS

直接数字频率合成器

DDS (Direct Draw Surface) is a Microsoft container image format developed in the course of their DirectX development. It is used in the field of gaming. All DDS formats, including alpha channels, can be read.

DDS (Direct Draw Surface)是在 DirectX 开发过程中开发的微软容器图像格式。它被用于游戏领域。可以读取所有的 DDS 格式，包括 alpha 通道。

The following DDS formats can be loaded into Cinema 4D as described:

Compression

压缩

Several compression formats are available for DDS images:

DDS 图像有几种压缩格式:

  • No Compression 无压缩 will generate no compression loss at all. 根本不会产生压缩损失
  • DTX1: Maximum compression; should not contain alpha channels. : 最大压缩; 不应包含 alpha 通道
  • DTX3: Medium compression; well-suited for alpha channels that clearly define regions. : 中等压缩; 非常适合于明确定义区域的阿尔法通道
  • DTX5: Low compression; saves alpha channels that define regions that define regions using grayscale gradients (= best quality). : 低压缩; 保存定义区域的 alpha 通道，使用灰度梯度定义区域(= 最佳质量)

MipMaps: MipMap technology, which is often used in the gaming industry, that projects textures onto objects in different resolutions depending on the objects’ distance from the camera. Additional lower resolution versions of the original texture are saved, which naturally increases the image file size.

MipMap: MipMap 技术，通常用于游戏行业，根据物体与相机的距离，将纹理投影到不同分辨率的物体上。其他低分辨率版本的原始纹理保存，这自然增加了图像文件大小。

Note that the output resolution has to be higher in multiples of 4 if one of the compression modes is used. Otherwise a warning prompt will appear and the resolution will be set to the next best size.

请注意，如果使用其中一种压缩模式，则输出分辨率必须以4的倍数为单位更高。否则将出现警告提示，并将分辨率设置为下一个最佳大小。
